Users of the Home Assistant Volkswagen Carnet integration are reporting authentication failures that prevent login, despite the official Volkswagen mobile app and web portal remaining fully functional for them.
Key Points
- Users report an "authentication expired" error when attempting to log in through the Home Assistant integration.
- The official Volkswagen Connect Android app and the vwgroup.io web portal continue to operate without issues.
- Affected users have confirmed their credentials are valid and that no multi-factor authentication is enabled on their accounts.
- The bug prevents the integration from connecting to vehicle data, rendering the Home Assistant dashboard unable to interact with the car.
