Frequently asked questions (FAQ)
Can Home Assistant run on a VPS?
Yes as a container. USB Zigbee sticks need bare metal/Proxmox passthrough – not a remote VPS.
HAOS or Docker?
At home with a stick: HAOS. In a datacenter: container + MQTT/Zigbee in the LAN via VPN.
Which port?
UI 8123. Never expose 8123 raw. Use a TLS proxy and strong auth.
Remote access?
WireGuard into the LAN or a TLS proxy. Nabu Casa is convenient; self-host keeps data in DE.
