Volkswagen blocks Home Assistant by requiring client assertion
Original: Volkswagen blocks Home Assistant by requiring client assertion
Why This Matters
Shows automakers increasingly blocking third-party smart home integrations
Volkswagen has blocked Home Assistant integration by implementing client assertion requirements in their authentication system. Users report login failures while the official Android app continues working normally.
A GitHub issue reveals that Volkswagen's car connectivity service has blocked Home Assistant integration through new authentication requirements. Users of the homeassistant-volkswagencarnet integration can no longer log in to access their vehicle data, while the official Volkswagen Connect Android app continues functioning. The issue appears to stem from Volkswagen implementing client assertion requirements in their authentication flow. Multiple users have confirmed they can still access vwid.vwgroup.io and use the smartphone app, indicating the problem is specific to third-party integrations rather than Volkswagen's core services.
