Handoff: "hasn't worked in months" = HA VM had no IPv4

Root cause

HA VM 706 (pve173) was running but had no IPv4 on enp0s18 — only IPv6 (ULA fd70:582a:b527:d4c8:fdaf:a8f9:f05a:40b6). DHCP method auto, empty address list. Uptime 57d at discovery → lease lost around late Aug 2026; why it never renewed is unknown. Effect: HA couldn't reach Mosquitto (.154), Caddy couldn't reach .146, Google Home → HA dead. The lgtv bridge on steel141 was healthy the whole time (polling correctly, connected to broker) — it just never received a command.

Fix (2026-10-22)

Omada reservation: network-tools/omada_reserve_ip.py reserve BC:24:11:3F:DC:7B 192.168.0.146
Re-ran DHCP from HA (ha network update enp0s18 --ipv4-method auto) → got .43 (router kept the existing lease; one disable/auto cycle didn't change it).
Set HAOS static: ha network update enp0s18 --ipv4-method static --ipv4-address 192.168.0.146/24 --ipv4-gateway 192.168.0.1 --ipv4-nameserver 192.168.0.1.
ha core restart.

Verified

.146 pings; hass.sethpc.xyz → 200.
switch.big_tv_lg_tv = off (matches TV) → MQTT path is live.

Not verified / open

Seth to test: "Hey Google, turn on the TV" (not done by me at 23:00).
Projector media_player.mitsubishi_projector unavailable — projector itself is off the network (PJLink :4352 closed, inactive in Omada). Probably powered off at the wall; separate from this outage.
media_player.lg_webos_tv_cd04 unavailable is expected while the TV is off.
Stale .43 lease will just expire.
Recovery path if HA goes dark again: reach it over IPv6 ULA above (ssh seth@<ULA>, bash -lc "ha network info").
