I have had them for almost 6 months without any problems. Whether through the application (eWeLink), voice control with Google Nest Hub, or simply as a touch switch, everything works fine. But let's start from the beginning.
First of all, in order for the switch to work, a neutral wire is needed (easy if there is a socket near the switch). To mount it on the wall, a box with "ears" is needed. If the old box does not have "ears," you can put small pieces of wood on the right and left sides, sticking them on the existing box, and then screw the switch onto them (photo). I'm just suggesting this as an idea.
Now let's move on to the settings part. Because I don't trust the built-in routers at all when it comes to their Wi-Fi and coverage, I preferred to disable their Wi-Fi and get a Ubiquity access point to have peace of mind (optional, of course). The switches do not support 5GHz network, so make sure that the 2.4GHz is enabled for it to find a network. For some reason, the eWeLink application could not directly find any of the 8 switches I installed, so I paired them with Wi-Fi by putting them in compatibility mode.
To enter compatibility mode, a button needs to be pressed for 5 seconds, and once the LED blinks 2 times quickly and 1 time for a longer period, then press the same button again for another 5 seconds. All of this is done while the eWeLink is in scanning mode for switches. The truth is, it took me about 10 minutes to set up the first switch, but after that, it only takes half a minute to set up each switch.
I have never experienced any random disconnections in the 6+ months that I have had them. When the power was cut off a couple of times, they automatically reconnected without any issues.
