Everything was ok but out of nowhere yesterday the wall switch is unusable, if you touch nothing happens, and it shows a red line in the third button.
I've removed it from the wall, checked the wires, everything ok.
What is happening?
For some reason the device was wiped.
I've joined its wifi, restored my configuration backup and it is working again.
In a Discord channel I was advised to run "setoption65 1" in the tasmota console, to avoid this situation.
