I found this today: Its primarily for fleet tracking, but it looks like individual users can access for free.
Basically they connect to your cars API for you, and you use their API to show the status and functions of your car.
It should be pretty easy for someone with the know how to turn this into an integration for Home Assistant.
I guess a person could sign up, configure their vehicle, get the API key, and then dothe rest necessary in Home Assistant.
Thoughts?
