Using fingerprints in Home Assistant

Sometimes it can be useful to load the fingerprints used for our pytest suite in the development of the Home Assistant component.

Set up bimmer_connected

Clone the repository to ~/bimmer_connected:

git clone ~/bimmer_connected


Make sure that you can access this path from inside your Home Assistant virtual environment!

Edit the _get_vehicles() function in and add the following code between self._get_oauth_token() and for brand in CarBrand::

from pathlib import Path
files = (Path().home() / "bimmer_connected" / "test" / "responses").rglob("vehicles_v2_*_0.json")
for file in files:
  for vehicle_dict in json.load(open(file, 'r')):
    # If vehicle already exists, just update it's state
    existing_vehicle = self.get_vehicle(vehicle_dict["vin"])
    if existing_vehicle:
      self._vehicles.append(MyBMWVehicle(self, vehicle_dict))

Set up Home Assistant

If not already done, set up the Home Assistant development environment.

Now start Home Assistant at least once and let all python packages install (hass -c ./config). If not already done, set up the BMW Connected Drive Integration in Home Assistant. Shut down Homeassistant afterwards.

In the Home Assistant virtual environment, install the freshly adjusted version of bimmer_connected:

pip3 install -e ~/bimmer_connected

Start Home Assistant using hass -c ./config --skip-pip and see all cars we have fingerprints of + your own cars.


If --skip-pip is omitted when starting Home Assistant, the version of bimmer_connected defined in homeassistant/components/bmw_connected_drive/manifest.json will be loaded and the Home Assistant last two steps have to be executed again.
