Hi,

Let it be said, I'm a complete Proxmox noob here. Trying my best, but it's a new world.

I have a Home Assistant setup running in a VM. I'm trying to seperate Z2M from Home Assistant and run it in a container instead so it is not dependant on Home Assistant.

I have a SLZB-MR3U which I use as Zigbee coordinator. I want to keep using it over LAN instead of USB due to the placement of my Proxmox server.

How can I make Proxmox "see" the SLZB-MR3U over my LAN?

I have setup the MQTT Broker and the Zigbee2MQTT container, but I need the latter to use the SLZB-MR3U. And I have no idea how to do that.

Just ask for details if needed, I have no idea which to giv up front.

Thanks in advance for any assistance.
 
The Proxmox host shouldn't need to see your coordinator (but can, depending on your configuration). Only your container with the Z2M service needs to be on the same network. The default bridge vmbr0 exposes all your services on the network your host is on [0], so the container should just have access to the LAN devices.

You can verify this is the case by trying to ping your container from another device on your network.

Ok, thanks for helping. It makes sense. I managed to get further with your help and you are right, the zigbee2mqtt actually sees my coordinator. Now my next issue is that I can't make zigbee2mqtt connect to mqtt. It just hangs when I attemp to start zigbee2mqtt.

Sigh...I'm so useless at this.. I have checked PW etc. But this is probably a question for the that specific mqtt community somewhere.


Edit: Looks like I got it started, some issue in my configuration.yaml :)
