I spent a small fortune to replace all the switches iny downstairs with these smart touch switches. I was nervous about the install. I did have it all done professionally as far as wiring them and such.In reading reviews about touch not working if installed with the power on before putting the glass plate on, I simply couldn't stop expressing this to my installer. In spite of that, I came home to find several of the switches powered on without the glass front plate.However, they still worked once the plate was put back on and they work amazingly.I use Google Home/Assistant for controlling my smart devices. The integration from the Tuya app was easy. Set up in the app was... Mostly easy. Oddly, the single switches gave me some trouble as the app was not finding them. To solve, I simply followed the reset instructions on the single switches (starting from the off position, press the power button 6 times and hold on the sixth press until you hear 3 beeps). I did have some difficulty and had to repeat that process a few times on a couple of the switches, but afterward, the app found them without issue.Oddly, the backlights are on when the switch is one, verse backlights being on when the switch is off... At least I think that's the case. It seems different on some switches. This doesn't bother me much, so I haven't fully investigated what's up.Overall, this was worth every penny I paid for the smart switches. I even hooked one up to my garbage disposal, which is nice when cooking and having dirty hands to be able to just.say, "Hey Google, turn on the garbage disposal."They look great. I have several dimmers, 1 gangs and one 4 gang. I was able to reduce the wall space needed for switches since a 4 gang controller is the same size as a single gang controller, and it all looks so much sleeker. They blend well I to my wall, making them less intrusive in the overall design.I highly recommend them, but be smart about the names of the switch in the app if you plan to use voice control. I jokingly named my kitchen lights, "Julia" after Julia Childs, but saying, "Hey Google, turn on Julia" is a bit creepy. ?
