Zigbee devices not responding after restoring a backup
Every Zigbee device needs to be sent a repair command to start working on your new Homey Pro. To do so, go to the device settings on the Homey Mobile App and click “Try to repair” under Maintenance. In the Homey Web App, you can right-click the device tile and click repair.
