Water heater = occupancy truth. New Pi package campsite_presence.yaml:
rv_occupied + phones_on_campsite_wifi template sensors (wifi one stays
unavailable until the MikroTik integration lands — load-bearing for the
dead-man trigger), MQTT bridging home, a local notify-only dead-man
(heater on, no phones on WiFi 3h), and disabled pre-staged lot-light
automations for the future shed Shelly.
dsi_fault_alert.yaml gains the Octavia MQTT relay (campsite/octavia/say)
so home HA — which has no file access — can speak through the verified
webhook path.
Home-side (UI-managed, not in repo): quick failsafe (both out of the
enlarged 150m campsite zone 25 min → fans/lights off + summary ping) and
heater failsafe (2h → heater off with bridge round-trip confirmation).
Both verified live; fan states snapshot-restored after the test.
