Drive HA's REST config-flow endpoint to add the NUT integration programmatically,
no manual UI clicks required. The script (setup-ha-nut.sh + ha-nut-setup.py) is
idempotent — skips if a NUT entry already exists.
Key finding: HAOS runs Tailscale as an isolated add-on container, so the HA core
container cannot route to Tailscale IPs. Added a LAN listener (192.168.3.11:3493)
to upsd so HA can reach it over the shared vmbr0 bridge. Both VMs (pfv-bms HA at
192.168.3.12 and pfv-tsys1 at 192.168.3.11) are on the same bridge.
Integration is live — sensors for battery charge (100%), status (Online), and
status data (OL) are reporting.
Secrets (HA token, NUT password) are read from ~/.config/pfvcluster/ and never
committed to the repo.

Architecture
- Proxmox hosts: 7 standalone PVE installs managed via PDM
- DNS: Technitium (authoritative) + Pi-hole (recursive) on pfv-netinfra-01/02
- NTP: pfv-netinfra-01/02 (redundant, LAN IPs, stratum 2/3)
- Production: Cloudron VPS in Reston VA (this cluster is R&D only)
- Backups: Proxmox Backup Server (PBS)
