wesandClaude Opus 4.8 6733a79390 canbus: furnace + water-heater status sensors (running + DSI fault) 
Decode node 89 (furnace) read-only: Furnace Running (page-3 b0 bit0) and
Furnace DSI Fault (b0 bit5), same type-0x1E DSI encoding as the water
heater. The furnace is thermostat-controlled, not a Lippert load — it
sits on the bus only to report ignition state. Captures only ever showed
0x80 (off), so the 0x81 running / 0xA0 fault bytes are inferred by
parallel to node 95; confirm on the first real burn.

Add Water Heater Heating (node 95 page-3 x[3] bit7 = burner actively
firing) — distinct from the on/off switch, which only reflects "enabled".

Carry all three through the MQTT bridge to home HA, add the furnace
DSI-fault Octavia alert mirroring the water heater, and update the README
node map (89 was "unknown switched load"). Campsite + home Camper
dashboards updated live.

# Campsite MQTT Bridge — publishes the OneControl CAN entities to home
# Mosquitto (cyrion, 192.168.88.69) via MQTT Discovery so they auto-appear
# on the home HA (192.168.88.40) as device "Campsite OneControl".
#
# Source side is the ESPHome IDS-CAN node ("OneControl CAN", entities
# *.onecontrol_can_*) — NOT the retired BLE integration.
# No water pump and no slide covers on purpose: those are panel-only
# (see canbus/HANDOFF.md safety notes).
