Hi, I run Z2M in a separate proxmox container. When I got home from work today, none of the connections work. I cant turn on lights from the Z2M ui or via home assistant. However, in the home assistant addon MQTT explorer I can see that devices (motion sensors for example) receives events.

I am running the SLZB 06.

I'm at a loss - could someone please help me figure it out? I've rebooted both the atenna and z2m.

All devices in Z2M reports "Data request failed with error: No network route (205)"

How is the SLZB-06 configured in z2m? By IP or hostname? If it’s by IP just triple check it didn’t have a new IP assigned

Maybe check the baud rate? I had issue with my fixed dongle; a recent update messed up the default settings
