SONOFFZBMINIL2 Extreme Zigbee Smart Light Switch (2 Way), Works with Alexa, SmartThings Hub, Google Home&SONOFF ZBBridge-P, ZigBee Hub Required, No Neutral Required

This sensor seems to work flawlessly, it connects to Home Assistant instantly as long as you have a good zigbee network in your dwelling. The wiring diagram can be a little confusing if you are not used to reading them. However most people that deal with Home Assistant can manage the install.

I got this to smarten up a light switch in my old house. I tried a dedicated smart switch from the same manufacturer first, but the electrical boxes behind my light switches were physically too narrow for it to fit inside. This little relay, on the other hand, was tiny enough to fit behind my existing light switch.Installation was easy enough. Trim excess wire off of the existing wire connected to your switch, so that there is no exposed copper when you attach the wires to the relay. The live wire goes in the "Load In" terminal, the other one goes in Load Out. Then wire the relay to your existing switch with the S1 and S2 terminals. (I harvested wire from an old computer power cable for this.)This is a Zigbee relay, so you will need some sort of Zigbee coordinator/hub in order to operate it. I had no trouble connecting it to my existing Zigbee network in Home Assistant using ZHA. Once set up, you can control it either via your Zigbee network or with the old physical switch.Do your research before using this. I've been advised to not use this with inductive loads, such as fluorescent lights.

Small, connects quickly, worked with SmartThings *eventually*.When in tried setting it up with the smartthings app it would not read the QR code and wouldn't finish the setup. Then later I found it insralled in SmartThings not assigned to a room. Every time I tried to pair it it seemed like it wouldn't stay in pairing mode, but I think it was connecting quickly and that's why the light stopped blinking, I just couldn't see that it was connected because it didn't work with the wizard.Will easily fit behind an existing switch

I bought this little box without knowing for certain if it would do what I wanted it to do. I put some smart wafer lights in my kitchen ceiling, but they do not respond to my SmartThings commands if the double-pole light switch they are connected to is switched off. I was hoping the installation of this switch would remotely turn the switch on and enable the lights to still work.When I first got this thing, I chickened out of installing it in this switch because I wasn't 100% confident I understood the wiring diagram, and I wasn't even sure it would do what I wanted it to do even if it was installed properly. So it stayed unused for about 6 weeks until I got the bright idea to use it on a single-pole switch that operated a track light over the kitchen sink that predated my foray into SmartThings connectivity. I still battled my insecurities about the wiring diagram but proceeded anyway, connecting the wires as I best understood it.When I powered the circuit back on, I could tell I had done it right because every time I touched the test button on the Sonoff module, the lights went from on to off or vice versa. But after downloading the recommended app (eWeLink) on my smartphone, I could not get the module to be recognized. With SmartThings, there is compatibility with other apps, so once you get the native app to recognize the device, you can import it into SmartThings. Anyway, I tried a number of times to initialize the module so the eWeLink app could connect, but never succeeded. Finally out of desperation, I opened up my SmartThings app and initiated the Add Device command, and it recognized it almost immediately. So now I can control these track lights through SmartThings. And the wild thing is that the single-pole wall switch now behaves like a double-pole switch. If you want to turn the lights on by activating the wall switch, you simply flick the switch up if it's down, or down if it's up. The "on" and "off" label embossed on the toggle is no longer relevant.

Purchased 3. 2 would pair but randomly disconnected from hub or turned on/off by themselves. The 3rd one would never pair.

I live in an older house and don't have neutral wire in my switch junction boxes, so I grabbed this to add smart functionality to my dining room light, which has direct wired LED tubes. Note: this is not suitable for a tube fixture that has not been designed or retrofitted for direct wire LEDs, as fluorescent lights are an inductive load and can fry the device when you shut them off. I used a short piece of lamp cord as a jumper between the switch connections and the device. With a little work, I was able to fit it into the shallow 2 gang box that switch is located in. Device paired immediately with ZHA on Home Assistant and has worked perfectly since.

For some reason, all the switches in my house are dark brown and have no neutral. Been looking to Alexify my light switches for a while now but could not find either brown switches or no-neutral alternatives until I found these.Installation in the wall was super easy and I could potentially easily fit one of these inside the box for each of the three switches in there.Pairing instructions aren't very clear and if you never used zigbee or z-wave items before, you might need some extra help. Apparently, I didn't need to download an app as my SmartThings hub easily found it and connected it to Alexa without problems.I wasn't sure how well it would work so I bought only 1 to test. However, after installation of this one, I bought 8 more! :) I might buy more soon.

Seems to work okay with Alexa. Couldn't connect to IKEA hub. LED for pairing doesn't work, I've never seen it light up. Size is good, really small, and wiring is easy. eWeLink app sucks, only works on 2.4ghz Wi-Fi, not 5ghz.
