As other people wrote, the diode on the switch is on when it is on, for me it’s not a big tragedy and a minus, I set it and don’t worry, if I need to turn on the light in the dark, I do it through the phone or by command. The bigger problem is that the switch is fixed only in certain places with screws, for example, I don’t have a place in the socket where screws, bolts, etc. are screwed in, an example in 1 photo, which means if you have the same one, then without crabs it won’t get up normally and you’ll have to wildly farm, if it works out at all, I managed to drive a screw between the socket box and the wall, but now everything hangs crookedly, obliquely, one corner is pressed against the wall, the other moves away from it, in general, the , I’ll do the repair, I'll put the normal sockets. The switches are also very sensitive, one of them is located behind the sofa, and sometimes, if you lean heavily on the pillow that acts as a backrest, the switch works, this is not a plus, not a minus, you can just move the sofa a little, but the fact is, they sensitive. If you like old switches that have two positions, up and down, then it’s more like just a button that you press and it stays in one place in any state. Two switches are connected to Aqara M2 and to Alice, in the "Light" category, sometimes a second or two out of sync starts between them, that is, the light turns on on one, then after a while on the other, with the same shutdown, I don't know which of them whole system problem. Also, when you turn it on / off, you will hear a loud click throughout the room, indicating that the switch has been activated. Well, actually, as they said, there really are traces on it. In terms of reliability and longevity, I will look further, it seems that nothing has shorted out, has not shorted out, has not caught fire, does not turn on the light by itself (it seems that there was just one moment and I couldn’t even understand from the magazine, I’m on the machine turned off the light or something settled in the switch except for Alice .
