I have a Wiser wireless 1-channel wall switch from Schneider Electric, the WDE002906 (shows up as FLS/SYSTEM-M/4 in Home Assistant). I am able to add it in ZHA and use it for a while, but after a few days/weeks it drops out and my automation no longer fires and no events appear in the logbook. If I remove the device and add it again it works for another while.
Looking at the network visualization, the button is connected to a Wiser wall dimmer in the same room. The value on the line is between 185 and 202 (not sure what this value is, is it LQI?).
I tried to search the logs but not sure what to look for…
How do I troubleshoot this?
