It turns out that it is not possible to backup and restore Zigbee with the Zigbee chip we use. So the service when it comes out will not have this feature.
As is the case now, the database contains all of the Zigbee devices, so when restored they are in the restored database also. But they must be manually re-paired. This is not difficult, but it is a manual process. They will reconnect to the database when they pair, so apps are not affected by this process.
