# Campsite presence / occupancy package.
#
# Occupancy truth: the gas water heater — always on while camping, always
# turned off when leaving (propane). WiFi presence (MikroTik Chateau
# device_trackers) is the second, internet-independent signal; until that
# integration is set up the wifi sensor reads `unavailable` and everything
# downstream treats it as "no veto" (failsafes key on GPS, dead-man stays
# quiet).
#
# Deploy to Pi: /config/packages/campsite_presence.yaml
# Repo copy:    canbus/ha/campsite_presence.yaml
#
# ⚠️ FIRST DEPLOY: `template:` may be a new domain on this instance — full
# core restart, then confirm the sensors exist (see dsi_fault_alert.yaml for
# the reload_all trap).
