Good video! I'm an learned electrician, so yeah, DON'T mess with something you don't know! besides that, I love the shelly's too, I actually use the 2PM one as a single relay to turn on 2 different light sources independantly: For example, in the bathroom I only turn on the furniture light when brushing teeth, washing hands, etc, it's even motion activated with a Aqara sensor (you gotta love HA), or when we take a shower, I go with voice command to turn on the main lights. In the office I'm using it to turn on two LED panels independantly from each other (mine or my wifes), so that when one person is here, not all lights are on, only the one you need. I've also installed the 4PM (DIN rail), to turn on different circuits in my garden, so we can have light at the place where we are, and not all around + at night, when someone would try to break in, there is an automation that turns on all off the lights when motion is detected on one of the cameras. Keep up the good work and nicely explained!
Not many have the opportunity to build an smart home from scratch. But if you have a hard time finding information about that. At least that’s how I feel. There are many products to “make something smart” or to retrofit smart home, prolly because there is a bigger market for that. But the topic of building an smart home from scratch is not that “mainstream”. For example there is not that much info on Bus System like KNX and so on. I’m grateful for any source / product for building an smart home from scratch.
Another great video, thanks. i put a smart relay on the extractor fan spur from my bathroom light. when guests would come to stay, they would switch on the main bathroom light, sending the loud extractor fan running. so i use a relay and a home assistant routine to disabale the extractor fan between 11pm and 7am so as not to wake evryone up or panic the guest who feels instant remorse (we've all done it)
You touched upon power consumption in your video a little. I’ve had PIR sensor switches installed about 11 years ago in my house. Recently I got a thermal camera for different reasons but discovered all my sensor switches emitting heat. I took one off the wall and measured it. 1 watt of consumption regardless of when switch relay was energised or not! I’ve got 14 PIR switches in my house, so it adds up to having 3x 4W 860lm light bulbs being switched on all the time. It’s a lot, and it demonstrates that while home automation makes life a bit easier, it comes at a cost of having an increased baseload. Now the more I look into it, the more I realise that the problem is the inherent inefficiency with AC-DC switched mode power supplies when load -> 0. They all consume power when there’s zero load! It’s something that manufacturers haven’t addressed properly yet, but I wander if they could be a bit more clever with their designs to eliminate this zero load drain.
Another couple of awesome benefits of smart relays: you can make your light switches do anything you want. Shellys, for example have a "detached" mode which turns that switch into an interface button that you can program to do whatever you want! Set a scene, turn off a different light, or fire an automation. On top of that, these relays can be wired into a 3-way (or 2-way if you're not american) circuit if you know what you're doing. I managed to do that for my main floor lights via access to the attic. I have a few shelly dimmers up there in junction boxes that are successfully controlled from a switch on either side of the room. It's great!
Did those shelly relays need a ZigBee Hub? Or did you installed the wifi ones and connected them directly to your router? I'm thinking of those relays, but I need the 2way ones (ie staircase which is controlled from 2 sides). And by the front door I need to connect a 2way relay (which will control 2 build-in lights) with a motion and light sensor, so they turn on automatically only at night. (or manually with a switch). what would be the best choise? Can you send me the product names? Thanks!
@@gustonator Shelly’s use Wifi, so no need for an additional hub. And any of the Shelly’s can work with a 3-way circuit (or 2-way for non-Americans) as long as you have a constant hot wire you can access. The Hook Up UA-cam channel has a video about how to wire a Shelly into a configuration with multiple light switches.
I'm in the middle of doing some major system design for a venue. Basically the goal is to have a tablet mounted to the wall that controls everything in the room; lights, projector, roller blinds, sound system etc. To achieve this I'm planning on using a few simple things; - 1st is Home Assistant (which will be controlling things like smart plugs and switches) - 2nd is a raspberry pi running Bitfocus Companion (which will control both Home Assistant and everything else) - 3rd is a Tablet securely mounted to the wall, running "Full Kiosk Browser" with the Companion buttons on it for control. The main thing is getting all the right relay types for all the lights (I am wanting to keep all the switches that are there), then once I've fully mapped everything out I can get a qualified electrician to install it for me. In the main hall there are about 7 switches for the lights (I don't think any of them are dimmable)
@@HomeAutomationGuy Bitfocus is just a web based/network based control software that allows you to run macros on multiple applications and hardware at once. It's usually paired with a "Stream Deck"
Hey there, awesome video! What would be your suggestion of a solution when you are building a brand new house and want to do home automation? Would you still do it with relays and physical switches, and would you use some specific switch type?
In the USA we have Phillips hue set up, which required their own hub, it worked well through their app. That was until our hub became unresponsive and now I have to manually turn them on to the color I want. I am however interested in a relay to control outdoor lighting so we can turn on entryway lighting., via an app. So I’ll be looking into the home assistant option, thanks for your insight.
Since you mentioned the diagrams, I noticed that you had your blue neutral wire, illustrated to the center of the lamp in your brown hot wire on the shell of the lamp socket. That's backwards if we're talking illustrations... Awesome illustration ...
I recently deployed 20 switches (Sonoff of course) in the house in UK - after thinking too much how to deal with lack of the N in the switch box on the wall, I realised that all lamps in my house have all the necessary wires ... on the ceiling, where the lamp is connected. So now all my switches became smart ones ;-)
Can you provide a diagram pls? Does this also mean the switch on your wall will always stay on ON position otherwise the relay won't work otherwise ? Or can you still switch on via switch on wall and the the smart one?
@@bimiuk4051 You do not need to leave the switch on. The switch can work as a toggle. So you switch it, and it will toggle the light on or off. You can also toggle it on and off via the app or smart home system.
There are Xiaomi smart ceiling lights in most places of my home and wireless switches, so I don't need a lot of relays. But in few places, where I left "traditional" lights, I use Sonoff zigbee and WiFi switches and even Moes Dimmer. Of course, I use Home Assistant instead of their "default" ecosystems And I replaced traditional two-positional wall switches with non-fixing switches (in some switches you just need to insert small spring inside to make the button return after pushing)
Hi, thank you for your time to teach us! Got a question as a newbie i am with these smart things: if you would have smartify your lighting, what would you use for togling lights on/off (no dimming), a classic on/off swith or a one time push button that looks like a switch but comes back to initial state, ready to be pushed again. i would like the last option because with a switch you will get most times the on/off state reversed. but then, any of those relays out there to go with such a switch?
Thanks for another great video! Relays are such a great way to smartify a house and still keep it friendly to people that might not be familiar with smart homes in general. I wish I knew about these back when I used to live with my parents that had a chandelier with 12 x E12 Candle type light bulbs that were incredibly expensive to replace with Hue/other mdoels.
I really like the versatility of relais but I had to use a bunch of light switches instead. The reason is that I have an off-the-grid house where all lights are powered by 24V DC but all relais seem to expect 110/230V AC.
I’m thinking about getting the Sonoff No-neutral Mini. Need to find a small dumb reverse relay( big AC switch to connect low power DC instead of the other normal way round) as I don’t have normal switches at present and every example I find is huge and will never fit in a light box.
In your "Don't buy the wrong smart light switch" you mention at "8:30" that you use Zigbee as the protocol for your switches. This video kinda recommends Shelly which is connected via wifi. Reading about Shelly it sounds great - and it even support power monitoring. What would you recommend as the Zigbee alternative?
I use Zigbee for all my sensors and my smart light switches where it makes sense, but for those where I don't want to replace the switch or have a different device that I want to power I use Shelly. Sonoff have some good smart relays that are Zigbee based, but they make a loud clicking sound when they engage which I find annoying
This is the first video that I have ever upvoted (in 20 years using the internet). So many videos out there have a 5 minute intro begging for subscribers and upvotes. Your simple request was refreshing. Plus the video was informative. Thank you.
Philips have some CR10 dimmable 25 and 36 degree cone CRI 97. I have a boat load installed with shelly dimmers. Real nice in Switzerland with neutrals everywhere and light switches being instantly convertible into NC or NO push buttons.
Great video 👍. Smart relays are great and if there was one that would take 240v from a PIR and turn it into a wireless signal, my life would be complete 😀
Hi Alan. Thanks for another excellent video. Just came across your channel recently and I’ve been a happy subscriber ever since. Which relay of smart switch would you recommend for heavy loads like Water Heater, cooker or swimming pool pumps? Have you considered making the main switchboard smart? Thanks again?
I'd suggest looking at the Shelly devices, they have some DIN rail mounted ones that are capable of switching heavy loads. I have a few energy monitoring devices in my switchboard, but other than that everything is dumb. I rely on my heating system to turn on and off the water heater and the cooker and ovens use around 1W on idle. Also living in London, a swimming is not on my radar
Hi Alan. Thanks for your response and suggestions. I’d looking into the Shelly products….I’m in the Middle East so swimming pool is essential for hot summers 😂
We are building a new house and thinking about a smart home installation. What is more interesting to do, systems like KNX or those Shelly/Zigbee smart relays ? Price wise
Thanks for a great video. One question, can relays handle 2 way switching - i.e. 2 switches controlling one light. Most of the switches I have are simple one light one switch set ups but the stairs have a switch at the top and a switch at the bottom. Although I could have one switch physically connect and the second connect logically through Home Assistant, if there is somewhere I would prefer to work properly without HA it's the place where you can bounce down a flight of stairs if you cant see what you're standing on. I have looked at smart switches but haven't found one yet that can cope with proper physical 2 way switching.
Great content and just what the home automation novice needs to get started. I just flipped from another channel's video titled "Beginners guide to Shelly Relays" and 75% of a 13 minute video was how to wire the relays. I like your emphasis on leaving this task to professionals. I live in a country where DIY electrical work is illegal, for good reason. In fact every website that sells these relays is required to publish a notice that they require a licensed electrician to install.
Hey, Mr Guy, that was such a clear explanation with the moving wires, that I think I'm going to buy some of those Shellys. Can I buy them over here in the USA?
great video. Shelly seems to have the best reviews but do not seem to be Homekit compliant? I have moved from Smartthings to Homekit and need to replace my relays.
I don't think they are natively compatible with HomeKit, but I've seen several blogs that explain how to connect them in. I'm unfortunately not a HomeKit expert, but I wish you all the best with it!
A really great video, it's just disappointing that Shelly are predominantly operated via Wi-Fi I'm currently looking for this functionality and importantly reliability with HA but with Zigbee rather than Wi-Fi The only options seem to be rolling the dice on Amazon or Alibaba, and hoping for the best, not great when installing in the walls, whilst I have them open up for other decorating work
@@HomeAutomationGuy Thank you, I'll take a look. I'm trying to keep my WiFi free, and am favouring Zigbee (while also managing both Zigbee and WiFi channels, to reduce interference)
Hey, great video! Which product would you use for a three gang switch set? Our kitchen has one panel with separate switches for ceiling lights, island lights and cabinet lights. Not sure which would save the most space in the backbone, as electrician says there's no permanent live in the ceiling to be able to install at the rose for instance. The main lights are also on two way switches. Any advice greatly appreciated.
Thanks for this video and I do like the "moving" wires animations! I notice that you have adopted the term "smart relay" as used by Shelly to describe any kind of smart module. I think this is technically inaccurate (for example, a relay and a dimmer are clearly quite different) and potentially misleading. So, I prefer to name them as follows: smartmodule switch (solid state on/off control) smartmodule dimmer (solid state on/off/dim control) smartmodule relay (contact closure on/off control) As you point out some smartmodules are available that can work without a Neutral, but AFAIK there are none that use a relay for contact closure control. Relays typically need more power to operate than can be provided by a current through an LED bulb without it glowing or flickering when "off", so a smartmodule relay will need a Neutral.
I have been looking at the Sonoff relays for the last two years, but considering my sub-optimal Philips Hue experience (god their switches are bad and ‘Friends of Hue’ ones overpriced) and it’s inconsistent integration into HomeKit, I resolved to waiting for Matter to come into use before adding any more smart home tech. I love playing around with this stuff, but I don’t want to spend a few minutes explaining to family and guests how to turn a light on or off every time they are over. My wife just about puts up with it, most of the time. When Sonoff have matter relays that I can put behind my existing wall switches (1- 2- and 3-Gang), they will have all my money.
Hi! Great video! Do you know of any DC relays compatible with 12v (2 to 5 A is all I need) that provide a voltage reading in the app or Homebridge, or Home Assistant? Ideally something zigbee or lora or maybe matter (or wifi it it has a low power sleep mode chip for periodic transmissions of data ). I have some small solar controllers in my camper suv that I want to control based on weather, day/night, and or battery voltage. Any thoughts from someone like yourself, who has seen lots of models, would be amazing. 🙏
GREAT VIDEO. and yes love the diagrams as they do help make sense and even the super cheesy sense of humour. But dont quit your day job anytime soon. :)
Using a similar switch but control to physical light switch is different from one in the video. It uses output and input from relay to complete the circuit to switch. States in instructions in red not to connect live to it 😅 Should check what's the voltage of it one day.
Hello .. i just moved i to a house and i want to make some automatizations...but...i have some problems...2 lights from my living room and 2 from my dining area ar swithed on and off ffrom the same switch. Is there any way i can use some relays ot smart switches to disconect them one from another. And turn them on off separately with some pressence or pressure sensor.s? Everything is messed up. 😊
You can use smart light bulbs in those fittings, and leave the switch at the wall turned on permanently. Then you can control them via the smart home platform rather than the switch, and place covers over the physical switches with battery powered smart switches on top.
Great video ! I am looking for smart dimmer relais for homekit which do not cost 100 bucks, unfortunately i could not find any. Does someone know dimmers which would be good with homekit ?
Which relay would you recommend for a roller door for a robot mower. I need a 2 channel relay that works with home assistant. Are there any that have a combination of either wifi/zigbee/zwave together this radio frequency for a keyfob. Is it better to use a separate rf module and smart relay?
I use a Shelly 2.5 relay for roller doors. But I use it with Home Assistant and it's WiFi based. I don't personally know of any out of the box solutions that will work with a keyfob like you wish (that doesn't mean one doesn't exist!)
@HomeAutomationGuy after looking what's a available and speaking to an electrician, I would need a nc relay on each channel to prevent a short by activating both channels at the same time. Eg if I am playing with the door and an automation runs at the same time. I think I'll just go with the one smart relay. The aqara t2 runs on zigbee.
I have smart switch with neutral wired needed. Can I connect the neutral wire to smart switch (N-in), but connect neutral wire to lamp without using (N-out) from smart switch?
Interesting example, what make is the example ? Interesting because with that one, with it having a separate trigger wire, you can use it on a lugging circuit that has more than one switching point. I don't think any smart light switch does that.
Hi, with these relays can i have one for my wall sockets? And am i able to get relays that physical turining o. Can be prevented and only switched on by the person having the app or website?
I’m trying to find a smart relay that uses zigbee, and can work in a 3-gang switch and has dimming functionality. Any idea if such a product exists, or am I a dreamer?
So does the physical switch just change the state of the relay? For example, the switch is in the on position with the light on, I then turn the light off via HomeAssistant so now the light is off but the switch is in the on position. What happens when i flip the switch to off?
Yes, the switch becomes a toggle. So the light switch position doesn't match the "state" of the switch anymore, and that really annoys my OCD. This is why I personally use smart switches instead of relays. Relays are a good idea if you have specific styles of switches that you want to maintain - or find some press button style switches that don't show their state via an up down position.
I want to be able to, when someone makes a booking into my Airbnb I want that booking to trigger the sauna to heat up and when the door opens for my virtual recording to treat them by there name can we do this ? How much to consult with me ?
I’m looking for one that takes the load off the switch. I have a smart switch but the limit is 300 watts of power. So I want the smart feature but looking for a way to have the load off the relay switch I place. So the smart switch doesn’t carry the load. Any advice?
5:58 if you don't even know what a neutral wire is or why it's important, you shouldn't be messing with electricity, period. my father was an electrician, so i probably know more about electrical installations than the average joe, but i know there is still stuff that i don't know.
liked, subribed, any tips and trics on matter & thread for a new house? use HA als central unit? Matter & thread gu10 downward lights but 'im stuck at the switches? What should I take? I would like 4 buttons on every switch so I have some ones left for new functions I would like to add. Matter & Thread switches with mutliple buttons, where are they?
I wish Shelly smart devices were compatible with 12Ga wiring required in new homes. My Home built in 2010 has zero 14 ga wiring. Our home inspector won’t allow them in any switch boxes because you’d have to lower gauge which isn’t allowed by IRC. Hey Shelly if your reading this how about make your devices capable of holding a 12 Ga wiring which is required on most circuits in the United States. It makes your device illegal to place behind light switch.
Though the Shelly or sonoff Wi-Fi products work well i would be hesitant to build a house around an all WiFi setup. Especially with technologies like BLE , or Thread/ matter there must be better solutions to have that don’t give you this big Wi-Fi radiation cloud in your home. When I started out with home automation 2& years ago I was using x10, which had a lot of flaws , but the usage of the existing wiring to transmit data didn’t cause any huge issues with radiation etc. I wish that somebody would take that concept and bring it into this century . It must be technically possible to achieve something like that and make it super reliable. Also 20 years ago I believe Jung already had wireless switches that used piezo technology to deliver the power to transmit its signal, without the need of batteries. Would be a perfect companion with ble
Nice work! Question- if you already have smart bulbs installed could you use the relay in conjunction with those bulbs? Why would you do that you ask? IDK LOL just curious, I can't think why I would want to. Any use cases where that would make sense? Personally I am smart bulb poor- I have so many that I am locked in to that option. Always looking for an excuse to buy more smart stuff however!
Actually, you can. If you want to use Adaptive Lighting (also called Circadian Lighting) with your ambient White CCT bulbs, you will need (use) the relay (or certain smart switches) to maintain power to the smart bulb. The wall switch can then the use to give the perceived impression of a tradition wall switch or dimmer. You will need Home Assistant to manage this. Ideally, you could also use a relay and bulb using the same protocol (e.g. Zigbee, Z-wave, Thread) and use binding. Home Automation 401!!
Just be aware that if the smart bulbs lose power they'll be unavailable in your home automation system. If they're Zigbee they also will stop acting as repeaters when they're off and may mess up your Zigbee mesh network
Is there a Smart Relay (either for DIN or into the wall socket) that supports LAN cable instead of wifi? I do not want to rely on the wifi connection for them.
I'm in the process of smartifying my home now and I've seen this relays before. My problem with them is space in the wall is already limited so wouldn't it be tough to fit these in already cramped gang boxes?
Ever come across a dumb small relay that is switched by high AC but connects a small current? My current light switches aren’t completely dumb but also not smart. They can be turned on by RF and use a tiny amount of current. I was thinking of connecting them to a relay and the relay to the switch connectors on a No-neutral Sonoff Mini. I have no neutral wire. I can easily find relays that are switched by AC 230 but they are humongous.
Hi, I'm looking at zigbee+rf relays as I don't have neutral at the switches and I want to install relays in the roofspace and use RF switches instead to switch the relay (as well as Home Assistant). Do you know of any good model that would allow that (and pair with HA)?
I have 1 room where i could use a relay, all other rooms use round dimmers that i turn, iv been looking for a video about smart dimmers but dont find anything good.
so i use smart lights, they are set for times and intensities etc, different scenes and voice commands. when i have guests they will switch the physical switch off, urggghhh. with one of these my smart lights will still work as planned? even when guests fiddle with the switch?
I'm searching for a smart relay that will keep power to my smart light bulbs (hue) and will act light a smart switch, but then also act like a regular dumb switch if there is no connection to the hue hub. Basically internally programmed, IF connection --> send signal to Hue hub to toggle, IF no connection --> power to lamp via relay. This can probably be done with ESPHome and Shelly, but shelly is Wifi, and not zigbee. If this doesn't exist, how do people react when the hub or network is down. My philosophy for home automation follows, "An escalator can never break: it can only become stairs".
The Aqara H1 Smart Switches have "Decoupled Mode" which can do exactly as you describe (With some scripting to switch it to non-decoupled mode if your Automation System is down)
Using a smart switch for a led will work but you will need a capacitor 1 micro farad ( looks like an upside down U so 1 u) connected across live-neutral
Thanks for the video! I have a conundrum, after hearing you talk about trying to keep things looking nice-I thought maybe you could help. I have a bathroom with an exhaust fan/light over shower. I wired whole house on Lutron RA2. I wanted to use the Lutron combo switch to operate fan w/timers and light separate all in one switch. The light is LED and Lutron’s combo switch only works with fans + lights that are halogen.🙄 Is there a Lutron compatible relay or something I could use with a Lutron 3button pico remote that would have one button for fan (program it to just be 30min timer) and one button each for on/off of the light and fan? Or something else that wouldn’t look like garbage? Single gang for minimal switches. 🙏
@@HomeAutomationGuy ah interesting. What if we weren’t talking about Lutron? Same scenario-single gang to control a fan (with timer ideally) and an LED light.
Many smart relays are not made for switching LED lights! I've had problems with this myself. This who have the 'zero crossing ' feature are great at controlling LED lights
So you seem like a mostly Zigbee guy, even though the Shelly relays are not Zigbee you prefer those over others? I ask because I need some relays but really do not want to use Wi-Fi smart devices and prefer Zigbee. I actually don't have any Wi-Fi smart devices in my home right now, and don't even know how to connect them to home assistant if I were to get any. I strictly use Zigbee right now.
I used to be against WiFi devices too, but now I use them if the features of them are better than the Zigbee alternatives. This is how I feel about the Shelly, they're great, reliable and open. Home Assistant auto discovers the Shelly devices once they're connected to the WiFi and they show up as normal switch entities.
How I can operate this smart switch when I'm not at home? It's connected to wifi but when I'm on driveway my phone isn't connected to wifi and I can't operate switch. Feel so dumb with new technologies
Your Wi-Fi is connected to the internet. Your phone is also connected to the internet. That’s how it works. If it doesn’t work for your, then there’s something blocking the smart switch’s access to the public internet, limiting it to only access your local network.
@@Rediwed1 but when I'm not at home my phone is not connected to wifi. I use this smart switch for territory lightning but when I'm on driveway I'm too far to turn on lights. For my understanding there is option connecting with cloud but I doubt that I will get it. Maybe switch works perfectly fine with Alexa but this far I can't operate switch from a distance
@raitisvjaters9737 Yes, you will need a smart home platform that allows for connectivity outside of the home. Alexa is an option, but not a good one at all. If you want simple, your best bet is something like apple HomeKit. If you want powerful and flexible, you’d need Home Assistant (and either setup port forwarding to access remotely for free, or pay for their relay service).
Dieing is always a possibility with electricity. Exploding is unlikely, unless you are dealing with high power. Not only should you be qualified to do the work, you need to understand the applicable electric code.
I use Shelly switches a lot . However they are quite unreliable, sometimes they will just not respond to the Wi-Fi or light switch commands and I have to open the light switch to disconnect and connect the Shelly just to restart it.
I have dozens of Shelly relays inside my walls (every single outlet or light is connected to one) and I don't have this problem you described. Isn't the problem in your Wi-Fi network?
Wifi probably is not the problem in this case because relay should respond to switch input even without wifi. Did you try restarting it from HA or Web interface?
Good video! I'm an learned electrician, so yeah, DON'T mess with something you don't know! besides that, I love the shelly's too, I actually use the 2PM one as a single relay to turn on 2 different light sources independantly: For example, in the bathroom I only turn on the furniture light when brushing teeth, washing hands, etc, it's even motion activated with a Aqara sensor (you gotta love HA), or when we take a shower, I go with voice command to turn on the main lights.

How is the smart relay now? After 1 year how usefull is it and do you have any complaints on the product?
@@adhilvp4751 it continues to be rock solid. No complaints at all!

I took one off the wall and measured it. 1 watt of consumption regardless of when switch relay was energised or not!

I'm in the middle of doing some major system design for a venue. Basically the goal is to have a tablet mounted to the wall that controls everything in the room; lights, projector, roller blinds, sound system etc.
To achieve this I'm planning on using a few simple things;
- 1st is Home Assistant (which will be controlling things like smart plugs and switches)
- 2nd is a raspberry pi running Bitfocus Companion (which will control both Home Assistant and everything else)
- 3rd is a Tablet securely mounted to the wall, running "Full Kiosk Browser" with the Companion buttons on it for control.
The main thing is getting all the right relay types for all the lights (I am wanting to keep all the switches that are there), then once I've fully mapped everything out I can get a qualified electrician to install it for me. In the main hall there are about 7 switches for the lights (I don't think any of them are dimmable)
I don't know what Bitfocus is, but the rest of your setup sounds very similar to mine!
@@HomeAutomationGuy Bitfocus is just a web based/network based control software that allows you to run macros on multiple applications and hardware at once. It's usually paired with a "Stream Deck"
Hey there, awesome video! What would be your suggestion of a solution when you are building a brand new house and want to do home automation? Would you still do it with relays and physical switches, and would you use some specific switch type?
In the USA we have Phillips hue set up, which required their own hub, it worked well through their app. That was until our hub became unresponsive and now I have to manually turn them on to the color I want. I am however interested in a relay to control outdoor lighting so we can turn on entryway lighting., via an app. So I’ll be looking into the home assistant option, thanks for your insight.
Amasing video! Thank you so much. Exactly what i needed.
Since you mentioned the diagrams, I noticed that you had your blue neutral wire, illustrated to the center of the lamp in your brown hot wire on the shell of the lamp socket. That's backwards if we're talking illustrations... Awesome illustration ...
Fair comment! I appreciate the note!
I recently deployed 20 switches (Sonoff of course) in the house in UK - after thinking too much how to deal with lack of the N in the switch box on the wall, I realised that all lamps in my house have all the necessary wires ... on the ceiling, where the lamp is connected. So now all my switches became smart ones ;-)
Perfect!
Yep, done the same with mine, all controlled via a rasperry pi
@@Mr31Vince mine too - home assistant of course ;-)
Can you provide a diagram pls?
Does this also mean the switch on your wall will always stay on ON position otherwise the relay won't work otherwise ?
Or can you still switch on via switch on wall and the the smart one?
@@bimiuk4051 You do not need to leave the switch on. The switch can work as a toggle. So you switch it, and it will toggle the light on or off. You can also toggle it on and off via the app or smart home system.
There are Xiaomi smart ceiling lights in most places of my home and wireless switches, so I don't need a lot of relays. But in few places, where I left "traditional" lights, I use Sonoff zigbee and WiFi switches and even Moes Dimmer. Of course, I use Home Assistant instead of their "default" ecosystems
And I replaced traditional two-positional wall switches with non-fixing switches (in some switches you just need to insert small spring inside to make the button return after pushing)
Hi, thank you for your time to teach us! Got a question as a newbie i am with these smart things: if you would have smartify your lighting, what would you use for togling lights on/off (no dimming), a classic on/off swith or a one time push button that looks like a switch but comes back to initial state, ready to be pushed again. i would like the last option because with a switch you will get most times the on/off state reversed. but then, any of those relays out there to go with such a switch?
Thanks for another great video! Relays are such a great way to smartify a house and still keep it friendly to people that might not be familiar with smart homes in general. I wish I knew about these back when I used to live with my parents that had a chandelier with 12 x E12 Candle type light bulbs that were incredibly expensive to replace with Hue/other mdoels.
I really like the versatility of relais but I had to use a bunch of light switches instead. The reason is that I have an off-the-grid house where all lights are powered by 24V DC but all relais seem to expect 110/230V AC.
Great video. Most houses I work on don’t have the neutral at the switch which is a shame. Still chasing the “perfect” solution
I’m thinking about getting the Sonoff No-neutral Mini. Need to find a small dumb reverse relay( big AC switch to connect low power DC instead of the other normal way round) as I don’t have normal switches at present and every example I find is huge and will never fit in a light box.
thanks for the video. I'm glad you're not sponsored though, that would taint your reviews for me.
In your "Don't buy the wrong smart light switch" you mention at "8:30" that you use Zigbee as the protocol for your switches. This video kinda recommends Shelly which is connected via wifi.
Reading about Shelly it sounds great - and it even support power monitoring. What would you recommend as the Zigbee alternative?
I use Zigbee for all my sensors and my smart light switches where it makes sense, but for those where I don't want to replace the switch or have a different device that I want to power I use Shelly. Sonoff have some good smart relays that are Zigbee based, but they make a loud clicking sound when they engage which I find annoying
This is the first video that I have ever upvoted (in 20 years using the internet). So many videos out there have a 5 minute intro begging for subscribers and upvotes. Your simple request was refreshing. Plus the video was informative. Thank you.
Thank you!
Philips have some CR10 dimmable 25 and 36 degree cone CRI 97. I have a boat load installed with shelly dimmers. Real nice in Switzerland with neutrals everywhere and light switches being instantly convertible into NC or NO push buttons.
They're really great, with so many positives! I just wish they'd fit nicely into my UK Back boxes.
I know this is an older video, but the animation was awesome. Oh yeah the stuff about relay was pretty ok too 😂.
Great video 👍. Smart relays are great and if there was one that would take 240v from a PIR and turn it into a wireless signal, my life would be complete 😀
Hi Alan. Thanks for another excellent video. Just came across your channel recently and I’ve been a happy subscriber ever since. Which relay of smart switch would you recommend for heavy loads like Water Heater, cooker or swimming pool pumps? Have you considered making the main switchboard smart? Thanks again?
I'd suggest looking at the Shelly devices, they have some DIN rail mounted ones that are capable of switching heavy loads. I have a few energy monitoring devices in my switchboard, but other than that everything is dumb. I rely on my heating system to turn on and off the water heater and the cooker and ovens use around 1W on idle. Also living in London, a swimming is not on my radar
Hi Alan. Thanks for your response and suggestions. I’d looking into the Shelly products….I’m in the Middle East so swimming pool is essential for hot summers 😂
We are building a new house and thinking about a smart home installation. What is more interesting to do, systems like KNX or those Shelly/Zigbee smart relays ? Price wise
Thanks for a great video. One question, can relays handle 2 way switching - i.e. 2 switches controlling one light. Most of the switches I have are simple one light one switch set ups but the stairs have a switch at the top and a switch at the bottom. Although I could have one switch physically connect and the second connect logically through Home Assistant, if there is somewhere I would prefer to work properly without HA it's the place where you can bounce down a flight of stairs if you cant see what you're standing on. I have looked at smart switches but haven't found one yet that can cope with proper physical 2 way switching.
Great content and just what the home automation novice needs to get started. I just flipped from another channel's video titled "Beginners guide to Shelly Relays" and 75% of a 13 minute video was how to wire the relays. I like your emphasis on leaving this task to professionals. I live in a country where DIY electrical work is illegal, for good reason. In fact every website that sells these relays is required to publish a notice that they require a licensed electrician to install.
Hey, Mr Guy, that was such a clear explanation with the moving wires, that I think I'm going to buy some of those Shellys. Can I buy them over here in the USA?
Yes, Shelly Store or Amazon. Shelly is Wifi only. You might also consider Sonoff, which are Zigbee also.
I'm not sure Rick, best to check their website to make sure they're 120v compatible. Glad you also liked the moving wires 😉
Im about to rig my new build in Australia with 40-50 shelly devices, pretty interested to see how they work out.
Few people would be interested in this mate
great video. Shelly seems to have the best reviews but do not seem to be Homekit compliant? I have moved from Smartthings to Homekit and need to replace my relays.
I don't think they are natively compatible with HomeKit, but I've seen several blogs that explain how to connect them in. I'm unfortunately not a HomeKit expert, but I wish you all the best with it!
A really great video, it's just disappointing that Shelly are predominantly operated via Wi-Fi
I'm currently looking for this functionality and importantly reliability with HA but with Zigbee rather than Wi-Fi
The only options seem to be rolling the dice on Amazon or Alibaba, and hoping for the best, not great when installing in the walls, whilst I have them open up for other decorating work
The newer Sonoff relays are pretty good. I think they come in Zigbee connectivity. Aqara have some relays too now, but I've not personally tried them
@@HomeAutomationGuy Thank you, I'll take a look. I'm trying to keep my WiFi free, and am favouring Zigbee (while also managing both Zigbee and WiFi channels, to reduce interference)
Hey, great video! Which product would you use for a three gang switch set? Our kitchen has one panel with separate switches for ceiling lights, island lights and cabinet lights. Not sure which would save the most space in the backbone, as electrician says there's no permanent live in the ceiling to be able to install at the rose for instance. The main lights are also on two way switches. Any advice greatly appreciated.
Thanks for this video and I do like the "moving" wires animations!
I notice that you have adopted the term "smart relay" as used by Shelly to describe any kind of smart module. I think this is technically inaccurate (for example, a relay and a dimmer are clearly quite different) and potentially misleading.
So, I prefer to name them as follows:
smartmodule switch (solid state on/off control)
smartmodule dimmer (solid state on/off/dim control)
smartmodule relay (contact closure on/off control)
As you point out some smartmodules are available that can work without a Neutral, but AFAIK there are none that use a relay for contact closure control. Relays typically need more power to operate than can be provided by a current through an LED bulb without it glowing or flickering when "off", so a smartmodule relay will need a Neutral.
Totally agree, I use this exact same terminology.
How’s your family dealing with the switch position doesn’t indicate on/off like it used to? Or are they just cool with it
The family is fine with it.... But it definitely messes with my personal OCD. The Shelly push button switches make it way less obvious and triggering
No different to two way switching in the UK. Switching from two places, top of stairs and bottom of stairs.
Thanks! can you hsare how to install a two way relay? I am not been able to control 1 light with two different switches
What's the pairing process look like? Will I need to get them out of the wall/ceiling if it loses connectivity?
Can you show how you cabled one of these up?
I have been looking at the Sonoff relays for the last two years, but considering my sub-optimal Philips Hue experience (god their switches are bad and ‘Friends of Hue’ ones overpriced) and it’s inconsistent integration into HomeKit, I resolved to waiting for Matter to come into use before adding any more smart home tech.
I love playing around with this stuff, but I don’t want to spend a few minutes explaining to family and guests how to turn a light on or off every time they are over. My wife just about puts up with it, most of the time.
When Sonoff have matter relays that I can put behind my existing wall switches (1- 2- and 3-Gang), they will have all my money.
Hi! Great video! Do you know of any DC relays compatible with 12v (2 to 5 A is all I need) that provide a voltage reading in the app or Homebridge, or Home Assistant? Ideally something zigbee or lora or maybe matter (or wifi it it has a low power sleep mode chip for periodic transmissions of data ). I have some small solar controllers in my camper suv that I want to control based on weather, day/night, and or battery voltage. Any thoughts from someone like yourself, who has seen lots of models, would be amazing. 🙏
Hi there lovely video. Does Shelley work with Hubitat?
I believe so. I found some drivers for it here
github.com/ShellyUSA/Hubitat-Drivers
GREAT VIDEO. and yes love the diagrams as they do help make sense and even the super cheesy sense of humour. But dont quit your day job anytime soon. :)
This is all just a hobby, I'm definitely not quitting the day job! Thanks for the message though!
Using a similar switch but control to physical light switch is different from one in the video.
It uses output and input from relay to complete the circuit to switch.
States in instructions in red not to connect live to it 😅
Should check what's the voltage of it one day.
What about 6-7-7-6 switch scheme? Is there any relay to manage more switches in circuit?
Hello .. i just moved i to a house and i want to make some automatizations...but...i have some problems...2 lights from my living room and 2 from my dining area ar swithed on and off ffrom the same switch. Is there any way i can use some relays ot smart switches to disconect them one from another. And turn them on off separately with some pressence or pressure sensor.s? Everything is messed up. 😊
You can use smart light bulbs in those fittings, and leave the switch at the wall turned on permanently. Then you can control them via the smart home platform rather than the switch, and place covers over the physical switches with battery powered smart switches on top.
Great video ! I am looking for smart dimmer relais for homekit which do not cost 100 bucks, unfortunately i could not find any. Does someone know dimmers which would be good with homekit ?
I had a lot of trouble finding dimmer relays. I only found the Shelly, but I'm not sure if it works with homekit
@@HomeAutomationGuy thank you for the response! The relais from shelly i saw werent compatible with homekit, but i will check if I find any
Which relay would you recommend for a roller door for a robot mower. I need a 2 channel relay that works with home assistant. Are there any that have a combination of either wifi/zigbee/zwave together this radio frequency for a keyfob. Is it better to use a separate rf module and smart relay?
I use a Shelly 2.5 relay for roller doors. But I use it with Home Assistant and it's WiFi based. I don't personally know of any out of the box solutions that will work with a keyfob like you wish (that doesn't mean one doesn't exist!)
@HomeAutomationGuy after looking what's a available and speaking to an electrician, I would need a nc relay on each channel to prevent a short by activating both channels at the same time. Eg if I am playing with the door and an automation runs at the same time. I think I'll just go with the one smart relay. The aqara t2 runs on zigbee.
I have smart switch with neutral wired needed. Can I connect the neutral wire to smart switch (N-in), but connect neutral wire to lamp without using (N-out) from smart switch?
Any chance you could recommend a relay that works well with Hue?
(Shelly doesn't do Zigbee)
Interesting example, what make is the example ?
Interesting because with that one, with it having a separate trigger wire, you can use it on a lugging circuit that has more than one switching point. I don't think any smart light switch does that.
Hi, with these relays can i have one for my wall sockets? And am i able to get relays that physical turining o. Can be prevented and only switched on by the person having the app or website?
Are there relays that support two way switching?
I’m trying to find a smart relay that uses zigbee, and can work in a 3-gang switch and has dimming functionality. Any idea if such a product exists, or am I a dreamer?
Sonoff and Aqara make Zigbee relays, but I am not sure if they do any that are 3-gang and dimming.
If a relay is used to switch off a lamp, will the lamp still use some energy? Or does the relay itself keep using energy?
The relay will continue to use a little bit of energy to power the WiFi and onboard computer chippies
Is there a smart relay that is compatible with HomeKit? Thank you!
Not easily. You need to flash it with special HomeKit compatible firmware which isn't a walk in the park
So does the physical switch just change the state of the relay? For example, the switch is in the on position with the light on, I then turn the light off via HomeAssistant so now the light is off but the switch is in the on position. What happens when i flip the switch to off?
Yes, the switch becomes a toggle. So the light switch position doesn't match the "state" of the switch anymore, and that really annoys my OCD. This is why I personally use smart switches instead of relays.
Relays are a good idea if you have specific styles of switches that you want to maintain - or find some press button style switches that don't show their state via an up down position.
I want to be able to, when someone makes a booking into my Airbnb I want that booking to trigger the sauna to heat up and when the door opens for my virtual recording to treat them by there name can we do this ? How much to consult with me ?
Thank you! Very helpful
Do you know of any relay solution. for 3 gang/switch + 3 way + dimmer ?
I’m looking for one that takes the load off the switch. I have a smart switch but the limit is 300 watts of power. So I want the smart feature but looking for a way to have the load off the relay switch I place. So the smart switch doesn’t carry the load. Any advice?
Take a look at the Shelly Pro range of relays. They support 40A or so, and I believe they take the load off the switch.
5:58 if you don't even know what a neutral wire is or why it's important, you shouldn't be messing with electricity, period.
my father was an electrician, so i probably know more about electrical installations than the average joe, but i know there is still stuff that i don't know.
liked, subribed, any tips and trics on matter & thread for a new house? use HA als central unit? Matter & thread gu10 downward lights but 'im stuck at the switches? What should I take? I would like 4 buttons on every switch so I have some ones left for new functions I would like to add. Matter & Thread switches with mutliple buttons, where are they?
I wish Shelly smart devices were compatible with 12Ga wiring required in new homes. My Home built in 2010 has zero 14 ga wiring. Our home inspector won’t allow them in any switch boxes because you’d have to lower gauge which isn’t allowed by IRC.
Hey Shelly if your reading this how about make your devices capable of holding a 12 Ga wiring which is required on most circuits in the United States. It makes your device illegal to place behind light switch.
Though the Shelly or sonoff Wi-Fi products work well i would be hesitant to build a house around an all WiFi setup. Especially with technologies like BLE , or Thread/ matter there must be better solutions to have that don’t give you this big Wi-Fi radiation cloud in your home. When I started out with home automation 2& years ago I was using x10, which had a lot of flaws , but the usage of the existing wiring to transmit data didn’t cause any huge issues with radiation etc. I wish that somebody would take that concept and bring it into this century . It must be technically possible to achieve something like that and make it super reliable. Also 20 years ago I believe Jung already had wireless switches that used piezo technology to deliver the power to transmit its signal, without the need of batteries. Would be a perfect companion with ble
Nice work! Question- if you already have smart bulbs installed could you use the relay in conjunction with those bulbs? Why would you do that you ask? IDK LOL just curious, I can't think why I would want to. Any use cases where that would make sense? Personally I am smart bulb poor- I have so many that I am locked in to that option. Always looking for an excuse to buy more smart stuff however!
Actually, you can. If you want to use Adaptive Lighting (also called Circadian Lighting) with your ambient White CCT bulbs, you will need (use) the relay (or certain smart switches) to maintain power to the smart bulb. The wall switch can then the use to give the perceived impression of a tradition wall switch or dimmer. You will need Home Assistant to manage this. Ideally, you could also use a relay and bulb using the same protocol (e.g. Zigbee, Z-wave, Thread) and use binding. Home Automation 401!!
Just be aware that if the smart bulbs lose power they'll be unavailable in your home automation system. If they're Zigbee they also will stop acting as repeaters when they're off and may mess up your Zigbee mesh network
Is there a Smart Relay (either for DIN or into the wall socket) that supports LAN cable instead of wifi? I do not want to rely on the wifi connection for them.
The Shelley pro series that are DIN rai mounted work on Wi-Fi and have a LAN port for Ethernet connection
I'm in the process of smartifying my home now and I've seen this relays before. My problem with them is space in the wall is already limited so wouldn't it be tough to fit these in already cramped gang boxes?
Ever come across a dumb small relay that is switched by high AC but connects a small current? My current light switches aren’t completely dumb but also not smart. They can be turned on by RF and use a tiny amount of current. I was thinking of connecting them to a relay and the relay to the switch connectors on a No-neutral Sonoff Mini. I have no neutral wire. I can easily find relays that are switched by AC 230 but they are humongous.
We have neutral wires in uk lighting circuit, whatcha onnabowwt?
But they're not always available at the switch
No links for Shelly?
Hi, I'm looking at zigbee+rf relays as I don't have neutral at the switches and I want to install relays in the roofspace and use RF switches instead to switch the relay (as well as Home Assistant). Do you know of any good model that would allow that (and pair with HA)?
are there any smart relays that work in Europe 230V that work with thread? I can not find anything
"If you do something wrong you may explode!" 😂
I have 1 room where i could use a relay, all other rooms use round dimmers that i turn, iv been looking for a video about smart dimmers but dont find anything good.
so i use smart lights, they are set for times and intensities etc, different scenes and voice commands. when i have guests they will switch the physical switch off, urggghhh. with one of these my smart lights will still work as planned? even when guests fiddle with the switch?
I'm searching for a smart relay that will keep power to my smart light bulbs (hue) and will act light a smart switch, but then also act like a regular dumb switch if there is no connection to the hue hub. Basically internally programmed, IF connection --> send signal to Hue hub to toggle, IF no connection --> power to lamp via relay. This can probably be done with ESPHome and Shelly, but shelly is Wifi, and not zigbee. If this doesn't exist, how do people react when the hub or network is down. My philosophy for home automation follows, "An escalator can never break: it can only become stairs".
The Aqara H1 Smart Switches have "Decoupled Mode" which can do exactly as you describe (With some scripting to switch it to non-decoupled mode if your Automation System is down)
Using a smart switch for a led will work but you will need a capacitor 1 micro farad ( looks like an upside down U so 1 u) connected across live-neutral
Perfect video
Thank you!
W power point można takie rzeczy animować???
I did!
Thanks for the video! I have a conundrum, after hearing you talk about trying to keep things looking nice-I thought maybe you could help.
I have a bathroom with an exhaust fan/light over shower. I wired whole house on Lutron RA2. I wanted to use the Lutron combo switch to operate fan w/timers and light separate all in one switch. The light is LED and Lutron’s combo switch only works with fans + lights that are halogen.🙄
Is there a Lutron compatible relay or something I could use with a Lutron 3button pico remote that would have one button for fan (program it to just be 30min timer) and one button each for on/off of the light and fan? Or something else that wouldn’t look like garbage? Single gang for minimal switches. 🙏
I'm not familiar with Lutron, I am not sure that they are that popular here in Europe / UK
@@HomeAutomationGuy ah interesting. What if we weren’t talking about Lutron? Same scenario-single gang to control a fan (with timer ideally) and an LED light.
Many thanks broh
do smart relayswork with dimmer switches?
There are some smart relays that work as dimmers, but you need to be careful with what combinations you use.
Hello! automation guy. Let us see if you can be helpful to me! Can I connect a 3 gang wifi relay to my existing fan dimmer, if yes how?
is there smart relays that can be wired to something like arduino or raspbery pi?
That is outside of my comfort level, so I can really comment. Messing with higher voltages and home made equipment scares me 🤣
Many smart relays are not made for switching LED lights! I've had problems with this myself. This who have the 'zero crossing ' feature are great at controlling LED lights
App side of it ?
I make my own smart relays with esp32 or esp8266
So you seem like a mostly Zigbee guy, even though the Shelly relays are not Zigbee you prefer those over others? I ask because I need some relays but really do not want to use Wi-Fi smart devices and prefer Zigbee. I actually don't have any Wi-Fi smart devices in my home right now, and don't even know how to connect them to home assistant if I were to get any. I strictly use Zigbee right now.
I used to be against WiFi devices too, but now I use them if the features of them are better than the Zigbee alternatives. This is how I feel about the Shelly, they're great, reliable and open. Home Assistant auto discovers the Shelly devices once they're connected to the WiFi and they show up as normal switch entities.
i need a kind of relay which keeps the lights powerd all the time because my lights are also smart
How I can operate this smart switch when I'm not at home? It's connected to wifi but when I'm on driveway my phone isn't connected to wifi and I can't operate switch. Feel so dumb with new technologies
Your Wi-Fi is connected to the internet. Your phone is also connected to the internet. That’s how it works. If it doesn’t work for your, then there’s something blocking the smart switch’s access to the public internet, limiting it to only access your local network.
@@Rediwed1 but when I'm not at home my phone is not connected to wifi. I use this smart switch for territory lightning but when I'm on driveway I'm too far to turn on lights. For my understanding there is option connecting with cloud but I doubt that I will get it. Maybe switch works perfectly fine with Alexa but this far I can't operate switch from a distance
@raitisvjaters9737
Yes, you will need a smart home platform that allows for connectivity outside of the home. Alexa is an option, but not a good one at all. If you want simple, your best bet is something like apple HomeKit. If you want powerful and flexible, you’d need Home Assistant (and either setup port forwarding to access remotely for free, or pay for their relay service).
Not going to work for me, about 85% of my boxes are full of wiring. No space for a relay.
I wish my wiring was as new as 1950s :)
Can any one help me I need a wifi operated bell push switch
I haven't seen one of those gadgets yet that can fit inside a US single box with a switch in it.
Use wifi light bulb simpler.
Dieing is always a possibility with electricity. Exploding is unlikely, unless you are dealing with high power.
Not only should you be qualified to do the work, you need to understand the applicable electric code.

I use Shelly switches a lot . However they are quite unreliable, sometimes they will just not respond to the Wi-Fi or light switch commands and I have to open the light switch to disconnect and connect the Shelly just to restart it.
I have dozens of Shelly relays inside my walls (every single outlet or light is connected to one) and I don't have this problem you described. Isn't the problem in your Wi-Fi network?
Wifi probably is not the problem in this case because relay should respond to switch input even without wifi. Did you try restarting it from HA or Web interface?
I'm an electrician i can confirm. you will explode
See! I nailed it.
