Fun project. Though it’s kind of unreal how complicated it is to set up HA and I literally do this for a living, both embedded sw and backend web dev. Docker compose with a zwave management server, reverse proxies for TLS, vlan isolation for the server, macvlan for HA container so it does see the host network, etc, etc. All to turn on and off a lightbulb with the sun. All the while AI is telling me to configure thing…
I set up HA from scratch on a new mini PC with Proxmox and HAOS in about 30 mins having never touched either before.
For VLANs, I just used port-based VLAN to attach it to the IoT VLAN, with firewall rule to allow UI access, but Proxmox has tagging support if preferred.
