I don't know anything about Venus OS but was going to do Home Assistant automatons for our skoolie. Will check out out tomorrow.

I’m definitely setting up home assistant, a node, and plex servers on proxmox to consolidate to single piece of hardware for server.
But I went Victron and VenuOS is the open source variant of the CerboGX that can be installed on a pi.
Now I have on that same pi, 4 relays for automation!
