Great! I spent ages flashing my wifi Minis with Tasmota (and bricking half of them in the process) and now Sonoff come out with the ideal alternative which would slot into my extensive Zigbee mesh. It'll be interesting to see how these work with ZHA, if you have that.
ZBMini has finally been delivered to me. I must say I'm not satisfied with the quality of its power supply. It uses an capacitive dropper inside instead of transformer which means that the microcontroller, as well as its S1 and S2 outputs are not isolated from mains power supply. I prefer the design of Basic ZBR3 which has proper transformer. Also, I'm not satisfied with the switch delay of this mini. It's below 500ms, but still noticeable. I'll try to modify the RC circuit near the S1 and S2 inputs in order to reduce debounce time, hoping that debounce delay is not implemented in software.
Hello. Good job I switch to Zigbee since my bad experience with a DW2 door switch using obsolete 802.11b ... not working with Ubiquity AP. Anyway I would like to know if the ZBMINI can be powered with DC. I just need a device to monitor my garage door open/close status so I would power it with DC with a Reed switch. To your knowledge, is it possible ?
Can I check if the zbmini functions as a zigbee router? I have the zbmini connected to the sonoff hub and tried to connect a door sensor (also sonoff) but some how it is missing a 3 meters. Even when moving the zbmini 4 meters closer to the the door sensor it is still missing 3 meters. So I was thinking that maybe the zbmini isn't working as the router, but I don't know how to check this.
It should relay the messages automatically since it's powered constantly and its MG21 built which has the router functions available. Can't vouch for the firmware implementation. I would have to check in the Zigbee2Mqtt how does it appear as
Will the light switch work normally after this is installed? I'm trying to keep my house dumb while at the same time making it smart. I want everything to work normally and smart at the same time.
I'm planning to use this to make my current switches smart. Can this device also control external smart bulbs? Or is it just capable of switching mains?
You can't control external bulbs directly, but you could add this as an automation scenario (when switch gets toggled, turn light X) in the eWeLink app or using NodeRED - check out my Smarter Switch video
Thanks for video. 1. If wall switcher is on then is it poss switch off light with app ? 2. If light was switched off with app then is it poss switch on back with wall switcher ?
Hello, thanks for this review. I would like to know if the Sonoff ZB Mini has compatibility with the Google Assistant... I mean: can I say "OK Google turn on / turn off Sonoff ZB Mini" etc. Thanks in advance.
Hi can I use it to make my plug (socket) smart ? Or is it only usable as a switch for light ? Sorry if the question is stupid but I’m new to this smart home stuff
You can make the socket smart too but consider current draw. If you are fine with rating you will need to split the live wire and put this switch before your socket
Do you if you setup the swicth and then connect with an Amazon echo device with a zigbee hub built in, do you still need the app installed on your phone?
If you link the app via ZigBee to Alexa hub with Zigbee (not tested the compatibility as I don;'t have the zibee enabled alexa) then you won't need an app.
I was very excited to get this in the post yesterday. I wired it up to a light above my bed and can control it with a Lonsonho Zigbee wall switch and Sonoff Zigbee button all connected to the Sonoff Zigbee Bridge which all works perfectly. Only problem is when I turn off the light, I can hear a high pitched noise coming from the Sonoff Zigbee Mini. Any ideas?
I downloaded a frequency analyser app (I don't have access to any pro tools) and the ZigBee Mini emits a 7200Hz tone when it is off. The noise disappears when it is turned on.
Hi Mat, thanks for your videos, they are great! I have a question: Do you think there is a way of adding an extra microcontroller to the zbmini to let the zbmini understand more mqtt instructions like dimming etc (with actually executing the extra functionality by the MC)? The MC can maybe use the 3.3V/5V pins of the zbmini for power supply and the rx/tx pins for communication. I really don't know if there are any diy community efforts in this direction, that's why i ask :). My current idea is to use the zbmini to switch a 12V power supply which runs the LED strip plus a esp8266 to control the strip via WiFi. This rises the question why using zigbee at all :D (and not using a tasmotized sonoff mini for example). But all my IOT stuff is based on zigbee and honestly i don't want to use WiFi for my IOT devices. The only benefit i see for "my" solutions is that the WiFi connection is only active when the device is active, but at the end it's somehow unsatisfactory to use zigbee for switching and WiFi for controlling then. Thanks, moik.
It would be easier to get small ZigBee dev boards and make a small device yourself than try to modify the zbmini. I have a couple of these boards they look like esp32 d1 boards and have more pins than you would need for your purpose.
yeah the xbee boards ... they are annoyingly expensive. would be great if there will be a low budget alternative in the future like the expressif stuff.
Hello! I am new in Smart home. Just have Aqara hub and 1 switch. Need sonoff mini r2. Could you please tell me what I need: 1. Sonoff Mini r2 2. Sonoff Mini r2 Zigbee? Why? And and does it works with Homekit?
You would need the Zigbee version but I cannot confirm if it would work directly. The best approach if you want to mix and match ecosystem is through cc2531

Excellent video, I'm new with these switches and I want to place some of them in my house and I'm deciding between Sonoff Min (WiFi) and Sonoff ZB Mini (ZigBee), which one is better and why ? if I choose the WiFi one does it take part of my WiFi bandwith slowing down my entire "internet speed" ?

I'd go with ZigBee. They act at router for your mesh and are easier to control with 3rd party. WiFi speed wouldn't be affected until you have excess of devices

Hi! Other than lighting, can this be used with appliances like air conditioning units? Thanks! Helpful vid!
Yes they can as long as you stick to current rating listed for the product
Doesn't seem to be much separation between the high voltage and low voltage on the pcb.
The usual dilemma size Vs space.
Reason for flashing its firmware could be to add a temperatur sensor or other sensors
Dev pads are there. The main reason anyone is flashing is to drop the shackles of the cloud imposed.
But extra functionality is always welcome

You need a hub for ZigBee devices to link it with eWeLink. You can only bind it with eWeLink or HA. You can't have both unless you go with eWeLink API

Changes are small over the original design so the main points stand. The DIY mode is better now so it's little easier to deal with.
