Ever accidentally opened your car’s trunk by squashing the keyfob in your pocket? Or returned to your car after what should have been a quick charging stop, only to find out it’s not fully charged? I have! The app can alert you if you forgot to lock your car or accidentally left a door or the trunk open. Notifications: - A door is open. - A door is unlocked. - Charging stopped. Features: - Set the minimum time a door or trunk needs to be open or unlocked before you’re alerted. - Configure a State of Charge (SoC) threshold, so that charging is only considered stopped below this limit. - Choose whether you want charging stopped notifications when DC fast charging, or for AC charging as well. Supported vehicles: The app should work with all connected Audi models. Please let us know if you experience any issues. Disclaimer: Car Notifier is not affiliated with, endorsed by, or officially connected to Audi AG in any way. It uses an unofficial and undocumented API, which may change at any time. If the API changes, the app might stop working, and depending on the change, we might not be able to make it work again.
