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. Read more
