I just tried to migrate from Zigbee2MQTT to ZHA. After removing the entities and uninstalling Zigbee2MQTT, I installed ZHA. Unfortunately I was unable to pair any device. (Aqara sensors)
Then I tried Zigbee2MQTT but now unfortunately I can’t find devices anymore.
Is there a reset function somewhere? I had already removed Zigbee.db.
Did you remove them from the zigbee network? Devices wont pair again once they are assigned to a network until you remove them.
You will need to call the equivalent to ‘Remove Node’ from the ZHA/Zigbee device controlling the bridge, then set your device to pairing mode immediately after. It should receive the ‘remove node’ command. Now it will be able to be added by calling the ‘Add Node’ process.
