Seeing as I never get replies to tickets:

when I click on pair new device (ZigBee on iHost)

What does it mean? It isn’t pairing. I just clicked on button and last pairing was Friday.

It was on 1.11.1

After backing up my Flows on node Red and Homebridge I reset it and it ended. It would appear that some sort of flag is being set as true that isn’t being cleared.

Reminded me the importance of being able to back up the Zigbee network, which given Zigbee to Home Assistant and Zigbee2MQTT both use an interoperable standard file type would seem sensible.
Also scenes need to be able to backed up somewhere. I’ve largely moved over to Node Red Flows principally for that reason but oddly some devices only appear in scenes.
