A small system-signed bridge app reads the CAN service and publishes live vehicle data to an MQTT broker with Home Assistant auto-discovery, so the car shows up automatically as a device with sensors.

Published values include: SoC, range, HV voltage/current, power, speed, inside/outside temp, doors, windows, central lock, a charging flag, and an estimated time-to-full (there is no native time-to-full — see control). It also republishes the current speed limit / over-speed state from the map-matcher (see speedwarning).

The bridge joins a known Wi-Fi when in range, uses MQTT last-will for availability, and can fall back to a phone hotspot.
