Imperfect but about the best available now
October 15, 2018
I have purchased a number of different styles of smart switches to work with the SmartLife app. While this one isn't perfect it's the best available right now in my opinion. Unique to this switch is a small rocker under the main switch -- clicking the left side reset/reconnects the switch with existing settings, while clicking the right side is used to pair with the app. The reset function allows you to "reboot" the switch with existing settings without cycling the power at the circuit breaker.
The blue Wifi symbol is lit all the time, and the green LED lights up when the switch is on. Both of these are a little "fuzzy" in appearance but are readily visible in almost all lighting conditions while simultaneously not being obnoxious.
The white color of this plastic is a pretty good match for standard switchplates from Levition or Lutron, unlike some other brands. There is a metal bracket behind the plastic that has threads for the switchplate screws. Unfortunately this means that the short screws found with "screwless" wallplates do not reach. I had to replace them with 6-32 3/8" screws from a hardware store. In addition the metal bracket is in two parts, and only one part is attached to the ground wire. The ground wire attaches only to the top part (and not to any internal circuit board). I would prefer an all plastic mounting (and no ground wire) or a full metal plate (such as the Dewenwils switch sold on Amazon). The thicker mounting also does not allow the switch to protrude into standard cover plates as fully as a true Decora-style switch but it's not bad.
The relay clicking noise isn't that loud and doesn't have a cheesy "sproing" sound like some.
I'm still looking forward to the day where manufacturers understand that these switches go into real homes where they are typically wired in multi-gang setups and should work flawlessly with industry standard mountings. Also would love to see a switch where you click up/on and down/off rather than a button that toggles between on/off.
But for now... about the best available. Photo shows installation with an Eaton 9522WS Wallplate. Note how edges of switch are recessed behind wallplate a little more than they should be.
