Incident log
2026-07-22 — two HA instances controlling the house in parallel
Symptom: automations firing twice from a single physical trigger — e.g.
turn_on_led_nad_blatem_1 firing the same day from the same button press,
mirror_on at 04:30 and gniazdka_w_lazience_on at 05:00 all firing on
both instances.
How detected: comparing last_triggered from restore_state across the
two instances showed identical automation IDs firing at the same times on
both — the container on piha (homeassistant5, HA 2026.4.3, location_name
KEN, mounted at /home/pi/homeassistant/config) never actually stopped
running after the migration to the RPi4/HAOS instance at 192.168.31.7; it
stayed alive and MQTT-connected, so both were independently reacting to the
same physical events.
Root cause: instances.yaml had ken pointed at the piha container —
that was the pre-migration instance, not the real one. The actual home
instance had already moved to Home Assistant OS on a dedicated RPi4
(192.168.31.7:8123, ingress ha.kapala.org via NPM, confirmed HAOS via
observer :4357, HACS installed, 118 automations), but the repo never
followed the move.
Decision: 192.168.31.7 (HAOS/RPi4) is canonical ken. The piha
container is renamed ken-legacy in instances.yaml, status: archived.
Plan: archival import for historical reference → docker stop (not rm)
→ one week of observation → decide on docker rm. See docs/backlog.md
for the ha-diag-agent re-pointing and wind-down follow-ups this incident
generated.
