For the beginners who are trying this for the first time, my experience of issues encountered:
1.There is a specific direction for the Wemos Mini to be plugged in, follow the arrow on your LED Strip
2.If only the first and last LED lights up after plugging in, there may be some issue with the soldering/contacts with the pins (it was the ground pin for me), try to resolder the pins to the board.
Happy DIY/Automating.
It's amazing how many times I have to come back to this video 😂
Spot on tutorial. I have mine up and running following your instructions. Only thing I would add, is double check the LED strip and make sure you wire the LED strip with the arrows (on the strip) pointing away from the ESP8266.
Really appreciate how detailed this tutorial is :) worked a charm once I figured out the USB I was using didn't carry data
Glad it helped!
Thanks for this. Great video - really clear and easy to follow! My LED is now up and running and attached to HA.
Well done. clean and simple. Also a super concise view into node red... like seriously I need to start playing with that
Thank you - no point in overcomplicating things! The more you play the more advanced stuff you can do without it having to getting complicated!
Thanks for this tutorial.
It really helped me choose a good led strip to use with ESP8266 and flash with esphome.
Glad it helped!
Another well explained video. thanks for that!
Glad you liked it!
Thank you so much for this video! I've built and it works! Amazing!
Great to hear!
Excellent video, thanks. You explain everything very clearly
Glad it was helpful!
Thanks for this detailed video! Turns out it's pretty easy peasy, lemon squeezy 🍋
Glad it helped!
Great video, I think I'll have a go at this myself over Christmas.
Good luck!
Excellent video. All useful information and no useless banter.
Your explanation very help full. Really appreciate.
I like your style of explaining esp 32
Thank you very much, the chip I was using was actually an ESP8266 not the ESP32. The 8266 is a cheaper single core version, although both work in a very similar way.
Very useful, thanks Will!
Glad it was helpful!
Great stuff. Thanks.
Glad you enjoyed it!
Thanks for your support to HA community!!! you have one more subscriber
Thank you, much appreciated!
Hi, when i connect esp32 to my router it's all okay, but when i try to connect it to the router upstairs i got an 4 way handshake timeout. Do you know what this means? It's both 2.4 wifi
love it... very good clip ^^
Thank you very much!
Hey, any idea how can I upload my own scripts build in arduino IDE? And then choose the given preset with a int value?
Nice work! just what i needed!
Glad I could help!
@@WillSurridgeTech I fired one of my controllers (my bad), but i learned and got more on the way, thanks again!
Hello,
I have a question about the Addressable Scan effect. Is it possible to specify the color here?
greetings
what power supply did you use? did you have to use a 5v usb break out board? I think d1 mini usb is 3.3v
Is it safe to run that much amperage through the D1 mini? I've been reading that the most you should run is 1 Amp and with 60 LEDs on a 1 metre strip you're looking at 2ish Amps.
heyy..it all works fine for me. But when i try to change the colors, the led lights flicker, and sometimes the particular part is in a different color. Anything I messed up?
Thanks you helped me fixing the rgb color mix up
Glad I could help!
Hi Will. I followed the guide and purchased the wemos from your link. Everything worked fine for a couple of minutes but then the wemos got too hot and the light strip slowly faded out. The wemos no longer works. The USB adapter I was using to power it says its 5V 1.5A. Not sure what went wrong I've ordered another wemos but from a different source as the reviews for the ones on amazon say they are clones and the original ones perform better
Nice video! It help me a lot! Is there a way to turn on the effect instead of white? (whitout to go choosing it)
I have a Govee H6125. Is it possible to connect it trough Bluetooth with an ESP32 with Bluetooth? Can’t figure out how to do it.
So no issue with the data line being at 3.3v and the striplight at 5v?
Hi Will,
I followed your video and my led strip turns on and dims but if i for example change the color to red one led turns red the second green and third blue and so on. I cant get all leds to turn the same color. Is there something i can try to fix this ?
Thanks
Hmmm, that’s a very odd problem...if you have any strip spare then try it on that - making sure you change the number of pixels of corse
is this way better than the WLED integration? Which way is more user friendly? I mainly want to make a nightlight that automatically turns on when we turn our smart tv off. I currently have wled setup on a wemos d1 mini and hyperion on a Rpi zero combined for an ambilight on the back of our tv and these are set to turn on and off automatically when the tv turns on or off. Id like to have a nightlight set to come on and play a preset effect if the tv is turned off during certain hours. Would WLED be easier than esphome? can i copy the wled source code in the master file and paste it into esphome and compile it from esphome?
WLED is definitely more powerful; if you want more advanced function and effects then I'd head over there
If I understood correctly, both the LEDs and the ESP microcontroller will be powered by 5V.
By looking at datasheets, the ESP operates at 3.3V, so the GPIO pin will output 3.3V when high.
However, the "VIH" (High-level Input) for the LED controllers is 0.7VDD; which I understand as 0.7*5V = 3.5V, which is higher than the 3.3V output from the microcontroller.
Do we need some kind of voltage conversion? Or do we just hope for the best and operate slightly outside the manufacturer margin? Or is my understanding wrong?
(I want to build one of these, so this is a concern I have.)
If you're only doing a short run it will work fine :) For longer runs you will want a logic level shifter (amzn.to/2X5fjf1) or you could use WLED (ua-cam.com/video/HPAPAPn2kME/v-deo.html) and select the option to skip first LED - this increases the voltage for you by using the first LED as a voltage shifter
Hi Will, could you please suggest how I can add more lights effects than the standards given in ESPHome light-effects for example collorPaletteLed, colorTemperature, cylon, DemoReel100, Fire2012, and more. These are examples of FastLed. Kindly suggest.
They are the only effects you can do with ESPHome; if you want more effects I'd suggest WLED (ua-cam.com/video/HPAPAPn2kME/v-deo.html)
Thanks for the useful tutorial.
However, if I set the effect and turn off the light and turn it on again, the effect is set to none.
How do I make the effect settings persist?
Maybe try using NodeRed or automation to call the effects, if you just want to use lovelace to turn it on, you can expose the nodered module as a switch. This is example of the Data Json format I use: {"effect":"Rainbow Effect With Custom Values"}
Name of effect is specific to what you add to your yaml.
this is cool!
just for my understanding, all the required power for the LED strips comes form the Wemos D1 Mini (which is powered by a USB mini port)... right? and this is possible because the selected LED strip is 5V... while it will not work if the LED would be 12 V... is that right?
if for example I have a two meter LED strip -> 0.18 W *60 (LET per meter) * 2 (2 meters) = 21.6 W ..... with a Voltage of 5V -> 4.32 A
Where can I see the Ampere ? will it work also for power injection the same configuration?
Thank you!
You are correct, for this setup, I got all the power from the D1 mini. The D1 mini runs on 5v so if your LEDs ran off 12V this setup wouldn't work. That's the correct calculation too, my PSU is rated at about 2A so as long as you don't have full brightness white on constantly then its fine. For power injection, you just need to connect the power from the same place to the same pins somewhere down the strip
If you want to run more LEDs then check out my other video using WLED and a beefier PSU where I also include some power injection!
Hi, great video, thx. I have question how to manage many ESP devices and avoid to lose them after router restart? I can add only 10 static IP. What if I add the new device to ESP integration with host name, is this help me?
You can add a static ip on the device (esphome.io/components/wifi.html) or look to upgrade your DHCP server away from your router - I use pihole (tutorial video on it on my channel)
can you please share the whole cave_led.yml file? you went so fast with the effects that im sure it confused others as well. i really need the syntax n format of multiple effects
Nice video
Thanks Daniel!
This is exactly what I was looking for. However, instead of effects, how can I address and change colours of individual LEDs e.g. in a string of 4 LEDs?
Hi Will, Thanks for creating such an informative video. Arduino source code (.ino) is missing if we are using esp8266. Could you please clarify the doubt?
Hi Sanjeev, you dont need arduino code at all - if you use the ESPhome addon in home assistant then you can write in yaml your settings and it will create a .bin file to flash your esp chip with
Great tutorial! I have been messing around with FastLED and powering my LED strip with an Arduino Uno but I want to make my setup run through HomeAssistant on my phone. I have some LED designs programmed through the Arduino IDE. How difficult is it to move these programs into ESPHome. Will it require starting from scratch in yaml?
Thank you
To be honest, I'm not sure - you could always use the mqtt library in arduino and integrate with that instead?
Awesome! If this helps somebody:
I had troubles with ESPHome flasher 1.3.0 and Big Sur.
After a couple of tries, 1.2.0 on Catalina, worked perfectly.
Good to know, I haven’t made the jump yet!
you are miss so must. like how to i connected to the home assistant server? USB all the time?
I have just one question. I can't find information, what's maximum amount of individual RGB LEDs that d1 mini can handle?
I'm not sure there is an official max; but if you're planning a long string and want complicated effects then look to use an ESP32 instead
I'm sorry but how did you do the "cave switch" condition? And what is your cave switch?
Very informative video, as I'm looking at adding some strip lights soon.
However, I think the table from The Hook Up is incorrect for referencing wattage. For the WS2812B it says, and you quoted in your calculation, that each LED is 0.18W. But, according to the manufacturer BTF, each LED is 0.3W which is almost double?
Great video! Finally a video which explains every from a-z without outdated info or missing info... By the Way... Do you know where to find extra Light effects or can you dive into more Lambda programming? I'd like to try to create some more advanced light effects ...
Glad it's useful! For more advanced light effects I'd recommend looking at WLED (I've done a video on that to for my outdoor lights)
The latest Home Assistant doesn't show the three dots for the menu that are used to bring up the color and effect panel. Instead, you have to click on the light icon. Great video. Thanks.
Thanks for the info!

Great and helpful video, thx a lot. A question: how can i configure it to turn green 100%, instead of the effect? In the "service data" i can add "effect" but adding color, like green: 100% or color_correct: [100%, 50%, 100%] does not work.... Thank for your reply in advance!
Check the light.turn_on action
esphome.io/components/light/index.html
Yeh, check the light.turn_on service - www.home-assistant.io/integrations/light/#service-lightturn_on
I'm terribly confused, you mentioned that you need a 5v module because the 3.3v version can't run off the 5v power supply - then went on to use the 3v and reccomend the 3v. Can you clarify please? Should we not buy the Module you've linked in the description and buy a 5v or use the 3.3v one that you said we shouldn't then said we should use?
I see many people placing a 100390 Ohm resistor between Nodemcu D(x) and the led strip data wire. Is it useless in this case?
Thank you
I'm not sure why they would do that as that would reduce the data signal voltage further. It's already 3.3V which is on the limit of what the LEDs will respond to (hence for a long you need a logic level shifter).
Will. Great video. I am generally new to this and have managed to set up a NodeMCU with WLED with a single NMCU per led strip. My question: Is it one NodeMCU per 'task'? Or can one set up a single NodeMCU that controls lights as well as having (say) a temperature sensor etc? I hope that makes sense...Also, does ESPHome replace WLED or would I need to use both things?
If you use ESPHome you can add in extra tasks just by listing them in the esphome config file; but with WLED I dont think you can add any other things to it
ESPHome and WLED are separate ways of controlling the strip - you need one or the other, not both
@@WillSurridgeTech Thanks Will. And when you say add in extra tasks, I guess you just assign a different pin right?
Exactly!
I'd love to add some more Smart home stuff to my house, like you said in an earlier video I started with a echo dot, I then added TADO for the Central Heating and today I took delivery of a Ring Doorbell. Now, I'm an average Joe and need things to be as easy as possible, so adding some LED strips under my kitchen units, looks great, I could also add some to my decking outside, but I can't solder and although I watched the whole video I lost you after the first few minutes - is there an easier way to do this without all the programming and soldering, or if I want what you have achieved I need to do the donkey work and learn a bit of coding?
Hi David, there are always ways around soldering if you get something like this (amzn.to/3i9JLwq) - make sure it’s compatible with your led strip - this is for GRB analogue strip, but you can find similar ones for digital strips too; then they can integrate with HA using the MagicHome integration
@@WillSurridgeTech Thanks Will, that looks so much easier. Do I need to buy specific strips of lights for that controller?
Yes you will need to make sure the strips are compatible - for analogue that means checking the RGB order, for digital it means checking voltage, whether it needs a clock etc...the product description should say
Would be great to have more effects toward my readings to be helping and warning rather than a Rainbow but takes me another lifetime to learn what you have :-) video was very interesting to watch and I have most of it setup to a point, just not like yourself! And I have no clue on the codes in Node-Red as I have never used it before. I also do not have ESPhome on my setup and seem to have a lot of Hugs as it is, and not at all sure if I have room for more or ways around your setup. All I know is my stairs need replacing and making back to New and was thinking of something like your setup but jsut in a different manner to get medical readings to control the lighting now that would be an effect to be studying :-) Thanks for your video which as helped me with clues to slowly trying!
Hey Will! Just wondering what the max current output of the 5v and 3.3v pins are on the Wemos D1 Mini.
Great videos! Thanks!
I believe it’s 500mA
@@WillSurridgeTech your LED strip would draw about 2.1 Amps, right? how could you use the 5v pin from the Wemos d1 mini then?
I'm guessing the 5V pin actually is connected directly to the 5V of the USB port so the current doesnt go through the D1 mini
The D4 is 3.3V correct? How can you control the data signal?
@@WillSurridgeTech That is technically true but you REALLY do not want to pump 2.5 Amps through that flimsy PCB, the tracks are not designed to do that. This is risking your esp dev board at bast and a house burning down kinda fire hazard at worst. I'd advise you to update the video accordingly. Otherwise thank you for the video the rest of it was spot on!
Thanks you helped me save a lot and have better leds than Philips even sells
Glad I could help
Cool video. If I wanted to make this same strip using all the same kit as you have but at 2m that means I'd need a 4.5A usb adapter, right? Do they exist? Are there other methods for providing power to the strip?
You probably won't be able to get USB ones, but you can get them in another format with much higher currents if required - amzn.to/2LVxEW2
Step up the voltage and get a power shield with a D1 mini. Can run up to 24v providing all kinds of power
Good idea, I've never used them before, but they look good! Thanks!
I tried this and it's not working. Light isn't turning on. Everything looks fine in the log. Using a NodeMCU esp8266. Any ideas?
Figured it out, LEDs werent getting power. Vin wasn't actually Vin - the pin I wanted was VV.
glad you got it :)
Great video will.
I came on looking for something on how to get ESPHome to do LEDs and this covers exactly what I wanted to know.
Thanks alot.
Glad I could help
"We should see our devices listed online", but i dont see that. i can see the d1 mini online on my router, but not in esphome.
In newer version is a green line. Its ok now
glad it works now
A led strip is a strip with led's on it.
No shit sherlock
Banter can never leave us brits
Great video btw. Keep it up!
3 questions (no googling)
1. What does LED stand for?
2. Where did you get that shirt?
3. What does FET stand for?
1 - Light Emitting Diode
2 - Shop called Renaissance (www.renaissance-menswear.co.uk) but made by a company called Merc
3 - Field Effect Transistor
@@WillSurridgeTech Where's my heart?
Nice video. Have you tried WLED? If so, what do you prefer from ESPHome?
Hi Paul, yes I have - I think they both have a place - sometimes WLED can be difficult and slow if you want to do something simple, but for more advanced effects and features it is much better. I'm going to a video using WLED in the next few weeks for my outside lighting so you can compare them both.
Just use wled more effects and just as easy to use
I find WLED can be a bit slower to respond to simple things, and the home assistant integration isn't as good for custom effects. I'm planning on doing a video using WLED for my outside lighting in the next few weeks to give a comparison.
Custom efects can be created by api or Simple Chrome extension named Blade's wled extension , than can copy settings to macro in setup And your Custom efect is done

Thank you for the link, I didn't know about that!
Aww men, just chill out, your content is useful, thanks for that but watching your vid I had a feeling that you will get a stroke or heart-attack in any moment. Just take it easy. :)
Thanks for the Video. You need to slow down mate. Also you probably need to upgrade your router, these days there is no need for a reboot...
Thanks for the tip
Great video but sometimes you are going to fast for people that arent familiar with it.
Sorry about that - I've slowed down since then!
@@WillSurridgeTech keep up the good work you got an extra subscriber from Belgium!
Thank you
I think you meant static DHCP lease. A static IP address I think means entirely bypassing DHCP which means you wouldn't have to make any changes in your router
good point!
Less head would be better, this way it is annoying for me.
Slooooooooow down, watched quite a few of your vids and been frustrated each time with the pace of them. Great content and knowledge but for me a slower pace would make them spot on. I dread to think what people outside the UK can understand. Not a complaint, hopefully constructive feedback.
Thank you :) I know i started off quite fast, hopefully my more recent videos are at a better pace for you
Blimey. Irritating!!
