SONOFF ZBMINI ZigBee Mini Smart Light Switch(2 Way), Works with Alexa, SmartThings Hub, Google Home&SONOFF ZBBridge, ZigBee Hub Required, Neutral Wire Required

I've now installed maybe 50+ of these, all controlled by zigbee2mqtt with a couple of different coordinators from sonoff to more exotic brands. These little switches work great with everything. They're small, easy to install, and reliable as heck. To be clear these are inexpensive, but they're not cheap.Things to watch out for:1. Get the right size standard screw driver. A good screw driver (not a cheap one) is a must to tighten the screws properly2. Don't strip too much wire. The screw terminals aren't too deep, and bare wire isn't a good idea.3. The plastic tab over the reset button can be tricky because it makes it a little hard to get tactile feedback to know when the reset button is actually pressed. If you remember to allow joining on your network BEFORE you power these, you'll never even need to reset them, though.To give you a sense of their quality, out of all the modules I've purchased (more than 50) ONE of them had a damaged reset button tab, and it wasn't damaged enough to be a problem. That's the worst thing I can say about these.

Hue bridge found it no problem. Now I can control the dumb porch lights and don’t need an unreliable timer switch anymore.

The SONOFF ZBMINI is a good solution to upgrade a regular switch into a smart switch.The device is thicker than expected, making it difficult to connect to an American single gang box with additional wires and a few wire nuts. The connector on the ZBMINI is good if their is very low tension on the wires, but as I pushed the entire assembly into the box, the connectors let loose. Eventually I switched the box for a double gang box to make room.The ZBMINI quickly registers when the light switch is changed, turning the light on or off.The ZBMINI easily connected to my Echo Plus Zigbee hub and is natively controlled by the Echo system. The response from the app is very quick, less than a second. The Echo app does not register when the switch is manually changed, so the app showed the power still on when I manually turned off the switch.I did not install the manufacturer app because the app collects some data about myself that I don't want shared.

A little hard to install because it's so small and I have a touch of arthritis. But it needs to be small to fit inside a utility box. If you have a neutral at the switch install it there; it's less than half the price of an in-wall switch. Otherwise install it in the fixture's utility box on the neutral side of the circuit and your existing switch will behave as in a 3-way. The ZigBee signal is strong enough to penetrate my metal utility box, which I thought might be a problem but was pleasantly surprised to see that it wasn't. I'll probably never buy in-wall smart switches again – I like this solution better.

Never could connect it. Not very easy to install and connect.

This thing is tiny enough to fit inside a normal switch box with lots of room to spare. It paired instantly to my Home Assistant Zigbee integration, and joined the mesh of other Zigbee devices from several different manufacturers.One nice feature is a pair of terminals that you can hook a manual switch to. This way, it can look and operate just like a "regular" light switch, and still be controlled by a smart home system. It seems this feature could also solve the problem of two-way light switches which don't have neutral wires available. Just put this device where the power feeds in and attach the switch loops to these terminals, instead of mains power.

I usually do not write negative reviews but I really feel I need to do it for this device. I ordered 1 and when I got around to install it, it worked for 10 min or so and died. I liked the size - not much compares, so I ordered another - same thing happened. I am using it to switch on/off to 9W LED spots - so I am not pulling a lot power. I opened the one of them and there are no sign of high power damage (like shorts) - they simply stop working after less then 1 hour. In the hour they work they do what the need to do, but it is not acceptable that they die right away

Works with my 3-way hallway light circuit that even has a 4-way switch in the middle. A much cheaper alternative to installing smart 3-way switches at every location in the circuit. The diagram is in the booklet. Certain 3-way wiring setups may require an extra wire running up to the device you're controlling, but mine did not. But yeah it's an easy way to add voice control to an existing 3-way or single pole circuit. It paired quickly with my Alexa Echo which is also a Zigbee hub. This device solved several problems for me. :)
