Lost connection to Zigbee devices

Configuration Zigbee
1

I am a HA n00b but have managed to control my water heater using a SLZB Zigbee coordinator and a Zigbee relay.
The coordinator in question is the one named “Framhus” and the relay is called “Namron VVB kjeller”
After working for months I suddenly lost the connection to the relay.
All updates for HA and coordinator are installed and warm and coold restarts tried but no connection to relay.
I know I can rip out and re-add devices but I don’t want to lose my setup and automations.
How do I get this on track again without losing everything?

Edit: For some reason HA seems to believe that the relay belongs to coordinator “Uthus” which I now have disconnected. It has always belonged to “Framhus”
Can the relay be “moved” to coordinator “Framhus”?

Have you checked the logs for clues?

Several weeks passed and several reboots, don’t think I can wind back…
(Fresh nick BTW :wink: )

It should say why it fails setup when you do a restart.

This is simple log after reboot:

the SLZB is reachable at this IP (it hasn’t changed?) Try reflashing the firmware on it.

.136 is the other (Uthus) that I am not using…
Framhus is at .193…
Both are up to date.
So does HA believe that the relay is connected to .136 and how did that happen?

I’m not sure I am following you - are you using two coordinators (as coordinators, not one as a coordinator and one as a router)? In a Zigbee network you can only have one coordinator, and it seems you have setup ZHA to use the .136 device as the coordinator, and it fails starting up because it cannot contact it.

Funny thing I haven’t…the one at .193 (Framhus) is the one I’ve been using.
Maybe move the one at .136 to the house and se if it does the trick?
