My #HomeAssistant system has been so stable for a year in the previous house and six months in the current place. But since an ordinary update last week, #ZHA handling of two zigbee devices (Aqara and Sonoff switches) has been constantly losing contact with them.

Guess I have some debugging to do. I got them back on line, and automations working again yesterday, but 12hrs later they've failed again.

Surely can't be be just me, given lack of changes – I'll check forums later I guess.
