Hi @Isage !

This part is «&nbsp;normal&nbsp;», the Zigbee2mqtt integration doesn’t yet handle restoring to another instance, but it’s a development in progress 🙂

If you want to follow the development, it’s here:

In practice, currently after a restore you have to redo the entire Zigbee2mqtt configuration, because the Zigbee2mqtt security key does not exist on the new instance.

I would recommend deleting your Zigbee devices in Gladys and recreating them.

I know it’s not pleasant to do, but as long as the Zigbee2mqtt integration doesn’t handle it we have no choice; it doesn’t really have anything to do with Gladys Plus 🙂
