To be honest, part of the reason I leaned towards having the radios on the same box, was simplicity.
I have a box, with a VM, VM is backed up, new box could be stood up if needed and restored from a backup.
The other was, when I knock over the network (don’t ask…), I don’t lose logged data from the various sensors.

If you did want to be able to fail over quickly, so long as you make the USB device paths match (ie, have them on the same device in proxmox), you should be able to swap things over inside 10 minutes.

“Bots? No, no, those are active users. They also don’t use adblockers, so they’ve better than regular users!”

Is there a particular reason you want to put your z-wave controller on the network, rather than just plugging it into the proxmox hardware? (Assuming I’ve read your post correctly). Are you looking to do high availability on the VM or something?

I found running HAOS in a VM, and passing through USB devices worked really well, and I just bought the bog-standard z-wave dongle from Aeotec.

I haven’t had a single zigbee button need a battery replacement yet.

Very accurate.
When we had the northern lights here, we pulled over on the way to the dark-sky location, and the aurora filled the sky.
After it died back a bit, we drove on to the dark-sky, where we spent 3 hours sitting in the dark working out if the green bits were going to spike up again.
