I bought 2 and they worked great so I bought 2 more. Just after a year, one of the first ones started dropping the wifi signal so I couldn't control it. Had to unplug it for a *long* time to get it to reconnect to wifi again when I plugged it back in. A few weeks later the second one started doing the same thing, but it's out of warranty too. Yesterday the 3rd one (that I bought 7 months ago) dropped the wifi and went offline, but it's under warranty still so it's going back. When they go offline, the blue LED goes out and it shows as "Offline" in the app. I can still turn them on and off with the button on the side, but that's it. The distance from the wifi router doesn't seem to matter, and unplugging them for just a minute to restart them doesn't work either. They need to be unplugged for at least a day it seems. Greg B

works but very hard to guess how to configure the app.

I purchased two of these, one paired just fine with my 2.4Ghz Wifi, but the other will just not connect no matter what i do, I must have tried 20 different times in 5 different locations in my house.
