About

Sentry Owl for Tesla

Features
Read full description

Sentry Owl tells you the moment someone is at your Tesla. Connect your Tesla account once. When Sentry Mode sees activity, you get one push with what happened. Open the alert to see the moment, the camera views, and what the car did about it. Pick what the car does when its own alarm goes off: stay quiet, honk once, or honk and flash until you stop it from your phone. Off by default, your choice always. Set a schedule so Sentry arms itself when and where you want. A different week for home, for work, and for everywhere else. The app goes by where the car reports it is. It never asks for your phone's location. Not sure yet? Open the app and tap the demo to see real alerts without connecting anything. Sentry Owl needs a Tesla that supports Sentry Mode. Some features depend on your car's model and software version. Sentry Owl is an independent app and is not affiliated with Tesla.
