Some time has passed since my previous post about fixing the issue that a Tesla does not allow scheduling preconditioning (de-icing) the car prior to a drive in the winter. The original post used an Azure Logic app as its core.
What you see above is a Logic app for my car only; the first step “When an event starts” is linked to a Tesla calendar in my personal Google Calendar. The “StartHVAC” and “EndHVAC” call out to serverless functions that hardcoded contain the data for my personal car. And the emails go to a hardcoded email address of mine. Totally not reusable, but working.
After publishing that post, people started to ask if they could use the same functionality as well. Ahm, I did just say it was not reusable, didn’t I? But being a good friend, I ventured out and rewrote the whole thing to support multiple calendars and cars.

The last few blogs had a “not my usual content” text here, but this one is about software development. As it turns out Tesla is missing a -for me- very critical piece of functionality; being able to start the airconditioning (AC) system at a certain time. It is possible to turn on the AC immediately via the app using the fan icon (see the image below), but not automatically at 06:00, while I’m still counting sheep in my bed.
But to my amazement, every Tesla car is accessible via the internet through a REST API. This API is what the Tesla app uses to access the vehicle. Using this API is not officially supported, but Tesla does not seem to mind people accessing it.
Okay! That is interesting! I’m a software engineer, I can handle a REST API…
