"Volkswagen modified its vehicle API in late May 2026, cutting off third-party tools like EVCC and Home Assistant from real-time vehicle data. The change affects owners of VW, Audi, Cupra, and Skoda EVs. The transition was announced on April 2, and the old API was shut down from May 18. Users lost access on May 27-28. The EU Data Act, effective September 2025, mandates easy access to vehicle data. VW now offers only delayed ZIP exports. Developers are seeking workarounds; a petition demands compliance."
