This project is a custom integration for Home Assistant that pulls in live data from Volkswagen's EU Data Act portal and turns it into trackable sensors. Under EU data regulations, Volkswagen is required to make your vehicle's telemetry available to you, and this portal generates a snapshot of that data roughly every 15 minutes. The integration downloads those snapshots automatically and makes the values visible inside your Home Assistant dashboard. Once set up, you log in with your Volkswagen ID credentials and select which car to monitor. The integration then provides a set of ready-to-use sensors covering things like battery charge level, target charge setting, current charging power, odometer, interior temperatures, charge state, door lock status, and whether the parking brake is engaged. Anything beyond that curated set is also exposed as a diagnostic sensor, disabled by default, that you can turn on individually if you want it. Before the integration will work, you need to set up a continuous data request on the Volkswagen portal itself. The integration only downloads data that the portal is already generating. If you have not activated a 15-minute data stream on your account, there is nothing for it to fetch. The setup steps for enabling that are described in the README. Installation can be done through HACS, which is a community add-on manager for Home Assistant, or manually by copying the component folder into the right directory. After restarting Home Assistant, you add it like any other integration through the settings menu. One noted limitation is that the integration does not import historical data. It only records values from the moment it is running. There is also a bundled command-line tool for debugging login problems outside Home Assistant, and a script for regenerating the data field dictionary from an updated official PDF.
