All my Aqara door/window sensors have started failing since last week. I have 6 GE ZigBee switches downstairs and almost all these sensors are connected to one of these switches. These have been very stable the last 6-7 months since I added these switches.
I have tried dropping and re-adding them, new batteries, hard booting the hub, rebooting from IDE. The only working sensor is connected to a ZigBee repeater. Interestingly at one point the repeater seemed to be hung too, I had to recycle it to bring it back to life.
Interestingly 2 of the failing sensors are directly connected to the hub. Almost all these sensors are in line of sight of the hub. Even though IDE tells me ZigBee is operational, I am not totally sure.
Any suggestions what else to try ?
