Sometime this evening, all communication between zigbee devices and HA seemed to have stopped.
I don’t recall having changed anything, the devices have not been unavailable for long enough to show as unavailable in HA.
I have rebooted the HA host computer, I have restarted the zigbee integration and I have unplugged and re-plugged the zigbee coordinator. None of those steps got communication for the zigbee network up again.
I can see my PIR’s tripping as they should but HA is just not seeing the traffic.
How can I tell if I suddenly have interference with a wifi channel (possibly a new network in the area)
What else can I try to figure out why things are not working ?
