Hi there,
I have (or actually had) a stable ZHA Zigee network running for years, mostly containing of powersockets and some lightbulbs. The controller is a Sonoff Zigbee USB dongle. Today at around 20:00 suddenly all sensors, switches, powersockets and bulbs stopped working. Ofcourse I tried a HA reboot, but unfortunately this didn’t help.
The strange thing is that, when I switch a powersocket on via Home Assitant, it immediately goes on, however the socket does not seem to report the status back to home assistant. After a few seconds, it displays an error “Action light/turn_on could not be executed. Connection Lost”. I am not a Zigbee expert, but it looks like the communication from my Zigbee controller to the zigbee devices is still operational, but that no signals are received back anymore. I am starting to expect my Sonoff controller died.
Nothing was changed. Anyone a idea?
