Defrost trigger for car windshield

Hi,

I’m working on a project where I want to automatically start preheating my car when there’s a high chance of the windshield freezing. I use a local app that sends me a notification when freezing conditions are expected. I’m looking for a way to trigger my car’s preheating system automatically based on that notification, so I don’t have to start it manually through the car app.

Does anyone have any ideas on how to make this happen or suggestions for a good trigger?

Thanks a lot for any input!

Welcome! :smile:

We need more detail… What car? What “local app”? Are you actually using Home Assistant at the moment?

I’ve edited your post title to make it more specific.
