All my Sonoff SNZB-02 temperature and humidity sensors have just gone offline… No major changes to anything. Tried doing a full restore from 2 day old backup but same.
Ah, as I’ve been typing this, I’ve noticed that one of my hard wired switches (Sonoff 01MINIZB) is also unresponsive. It shows as green on visualisation map, but when you toggle, it shows the error message below. Perhaps the temp sensors route via this one router?
