CarConnectivity connector for the Volkswagen EU Data Act portal (read-only)

CarConnectivity Connector for the Volkswagen EU Data Act Portal

A CarConnectivity connector that reads vehicle data from the Volkswagen EU Data Act portal (eu-data-act.drivesomethinggreater.com).

Why this connector exists

Volkswagen has blocked WeConnect API access for all 3rd-party integrations, which breaks the carconnectivity-connector-volkswagen connector. For personal use, the EU Data Act portal is the remaining access path. Its data has important limitations:

• Read-only. No commands are possible (lock/unlock, climatization, charge start/stop, etc.).
• ~15-minute cadence. Data is delivered as batch datasets roughly every 15 minutes, not live.
• Partial data. Some WeConnect data points are absent (e.g. GPS location; estimated range is often missing). Only the data points present in a dataset are exposed.

This connector authenticates against the portal (OIDC login, reusing the proven flow from the homeassistant-vw-eu-data-act integration), downloads the newest dataset per vehicle, and maps the available data points onto native CarConnectivity attributes as read-only values.

Prerequisites — enable continuous data on the portal first

Before adding the connector, you must enable a continuous 15-minute data request for your vehicle on the EU Data Act portal. The connector only downloads the datasets the portal generates — it cannot create the data request for you, and without an active request there will be nothing to fetch.

1. Open https://eu-data-act.drivesomethinggreater.com/ and log in with your Volkswagen ID (the same email/password you'll use in the connector config).
2. Go to Data clusters → Vehicle overview.
3. Connect your car to the site if it isn't already listed (follow the on-screen pairing/consent steps for your VIN).
4. Click Get customised data for the vehicle and follow the instructions to configure a continuous data request with a 15-minute frequency.
5. Wait until the portal starts producing datasets (you'll see ZIP files appear in the vehicle's data delivery list, roughly every 15 minutes). The first file can take a little while to show up.

Once datasets are being generated, continue with the installation below.

The connector polls at most every 15 minutes because that is how often the portal publishes new data — a shorter interval cannot produce fresher values.

Installation

pip install -e .

Requires carconnectivity>=0.11.9.

Configuration

Add a connector of type vw_eu_data_act to your carconnectivity.json:

{
  "carConnectivity": {
    "connectors": [
      {
        "type": "vw_eu_data_act",
        "config": {
          "username": "[e-mail]",
          "password": "your-portal-password",
          "interval": 900,
          "country": "si",
          "language": "sl",
          "brand": "VOLKSWAGEN_PASSENGER_CARS"
        }
      }
    ]
  }
}

Key	Default	Description
username / password	—	VW ID credentials. May instead be provided in .netrc under machine vw_eu_data_act.
netrc	~/.netrc	Path to a netrc file (used when username/password are omitted).
interval	900	Base poll interval (seconds, min 60). The connector also auto-schedules ~15 min after the newest dataset.
country / language / brand	si / sl / VOLKSWAGEN_PASSENGER_CARS	OIDC state components.
vin	—	Optional. Restrict to a single VIN; otherwise all consented vehicles are used.
hide_vins	[]	VINs to exclude.

Exposed data points (read-only)

EU Data Act field	CarConnectivity attribute
mileage.value	vehicle.odometer (km)
battery_state_report.soc	electric drive.level (%)
battery_state_report.charge_power	vehicle.charging.power (kW)
charging_state_report.current_charge_state	vehicle.charging.state
settings.target_soc	vehicle.charging.settings.target_level (%)
range (when present)	electric drive.range (km)
min_temperature / max_temperature	battery.temperature_min / temperature_max (°C)
window_heating_state	vehicle.window_heatings.heating_state
locked	vehicle.doors.lock_state

Fields without a native CarConnectivity home (parking brake, charge-mode options, raw diagnostics) are not exposed.
