Deploy Network UPS Tools to monitor the server-room UPS units and feed data to
Home Assistant for power-usage tracking.
APC Smart-UPS C 1500 is fully operational: battery charge, runtime, load,
voltage, and status all reporting via usbhid-ups + APC HID 0.100 subdriver.
upsd listens on Tailscale (100.121.189.98:3493) for HA polling; local upsmon
provides graceful hypervisor shutdown on battery-low.
Key deployment fix: the udev rule must cover SUBSYSTEM=="usb" (raw
/dev/bus/usb) in addition to hidraw, because usbhid-ups opens the raw USB
device file after dropping to the nut user via setuid(). Matching only hidraw
causes EACCES on driver start.
Tripp Lite UPS (09ae:3016) is blocked — driver matches TrippLite HID 0.85
subdriver but fails reading the 878-byte HID Report Descriptor (EAGAIN via USB
hub). Needs physical reseat to direct motherboard USB port. Driver masked to
prevent restart-loop spam.

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)
