OBD2 BLE for Home Assistant
Plug-inRead Bluetooth car sensors from Home Assistant
This integration connects Home Assistant to a Bluetooth LE OBD-II dongle and creates sensors from selected diagnostic commands. You can choose polling intervals and retain sensor values while the vehicle is away.
You need working Home Assistant Bluetooth coverage, including a suitable ESPHome proxy if the car is far from the server. The integration discovers specific advertised names and BLE services rather than every ELM327-branded adapter. A Classic Bluetooth adapter is a different transport and is not covered.
