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.

The campsite HAOS Pi now runs the ESPHome CAN node natively ("OneControl
CAN", *.onecontrol_can_*); the BLE integration is fully torn out (config
entry, custom_components on the Pi, stale MQTT registry orphans) and the
camper dashboard rewritten — water-pump tile dropped on purpose (pump is
panel-only), awning + fault sensors added.
New canbus/ha/mqtt_bridge_onecontrol.yaml (deployed to the Pi as
packages/mqtt_bridge.yaml) bridges the CAN entities to the home broker
via MQTT Discovery, same pattern as the gazebo bridge. Kept the old
unique_ids so home entity ids and recorder history carried over; added
an availability topic and explicit command-topic allowlists (3 switches
+ awning — a future debug entity must not become remotely controllable
for free). Round-trip verified from home HA.
