So ive updated my SHS to 12.12 and overnight my zigbee is dead. It started with my Tuya brand devices but now i cant add any zigbee devices either. I have snapshots of pre update but on boot it brings back 12.12. I did disconnect the ethernet during boot but this didnt really solve the issue! These are the messages im getting in the shs log and when i try to use a device i get a timeout message and when i try to add a device i get an unable to connect. I suspect the bridge may be faulty but i could add zwave so only the zigbee chip. I restored an older snapshot snd the issue remained BUT the zigbee stack warnings in the image did not populate the logs. Few question. If i change/replace my bridge (add new one first) then remove the old, Will all devices drop offline? Has anyone seen these messages before? Any clues? Much appreciated.
