Help - Deconz Wrong IP

My Zigbee devices have stopped working as Deconz is failing to start up. On investigation it looks like the Gateway IP has changed for Deconz so it can’t connect - however - I can’t work out where to set the gateway IP in HomeAssistant as it is now pointing to the wrong IP.

Any ideas?

I would remove Deconz and re-add it.

I have the same problem after a restore, the IP changed fron 172.30.33.1 to 172.30.33.4 If I uninstal deconz do I loose all my config?

Just to make sure you are doing the right thing: you’ll not uninstall the deConz software, but removing the integration from HA and than add it again and assigning the new IP in case it is not discovered automatically.
By doing so device names are preserved but you will lose the locations of the devices (if previously assigned)
