HomeAssistantOS - Configuring multiple network interfaces

I am running HomeAssistant OS in a Proxmox VM, on a network with multiple VLANs used to segregate systems. HomeAssistant needs access to three VLANs to operate properly.

  • I see that configuration.yaml allows for a network: section, but options are not documented anywhere.
  • From the terminal add-on, I see that ha network info shows all interfaces/vlans, but configuration from this tool is also not documented anywhere.

Is there anywhere I can find information on either the YAML or command syntax to properly use multiple interfaces?
