What is ha_vag-eu-data-act?

This is a custom integration for Home Assistant that pulls vehicle data from the official Volkswagen Group EU Data Act portal. Home Assistant is an open-source home automation platform that many people run on a local device to monitor and control smart home hardware. This integration extends it to display data from VW Group vehicles. The EU Data Act is a European regulation that gives vehicle owners the right to access data generated by their own cars. Volkswagen Group set up an official portal under this regulation where owners of VW, Audi, Skoda, SEAT, Cupra, Bentley, and Volkswagen Commercial Vehicles can request their vehicle data. Before this integration existed, people used unofficial third-party APIs, but VW restricted access to those in 2026. This integration uses the official legal route instead. The way it works: you first set up a continuous data request on the VW Group portal, choosing a 15-minute delivery frequency and selecting the full dataset rather than a charging-only subset. The portal then delivers ZIP files with your vehicle data on that schedule. The Home Assistant integration reads those ZIP files and turns the data into sensors you can display on a dashboard or use in automations. Data is read-only and updates roughly every 15 minutes, so there is no ability to send commands to the vehicle such as starting climate control or initiating charging. The integration automatically creates helper sensors for the Home Assistant Energy dashboard, tracking cumulative charged energy in kilowatt-hours, monthly mileage, and monthly electric consumption where available. It also creates a sensor for the energy added during the most recent charging session. Installation is done through HACS, which is the standard community add-on manager for Home Assistant, or manually by copying files. After installation you add the integration through the Home Assistant settings interface, select your brand, and enter your account credentials for that brand's login (VW ID, myAudi, Cupra ID, etc.). The integration is currently in beta and is intended for EU vehicle owners. Porsche is not supported because it does not appear on the same portal.
