"On May 27-28, 2026, Volkswagen deactivated the API that allowed owners of VW Group electric vehicles (VW, Audi, Skoda, Cupra) to access their vehicle data via third-party tools like EVCC and Home Assistant. This disrupted smart charging solutions, including solar surplus charging. VW had announced the transition on April 2, 2026. Developers are working on workarounds, but long-term free access is uncertain. The EU Data Act (2023/2854), in force since September 2025, is invoked; a petition demands enforcement."
