few days ago one of my ceiling lamps suddently disappeared from AP. According to AP logs, it just stopped communicating (without proper wifi disconnect). Bad is, that it didn’t try to connect again. I let it half a day like that and nothing … it didn’t even attempted to connect to AP. However BT remote was still working. Actually that was the only working thing.
After switching off AC power for like 10 seconds, problem was resolved. Other lamps are connected to AP for 17 days and still work.
However, i would like to know, what happend and how to prevent it in future, as i have full house of these lamps. Any ideas what could be reason? And is there a way to “debug” these problems somehow?
