My garage door is dumb and I searched for a way to make it a bit more intelligent, one way is to buy the HomeLink Module for your Tesla. But still, you have to interact with it to open or close the door and its not cheap. I already have a running IOBroker installation for different home automation things, TeslaMate and a big Zigbee installation at home, so i have a good base to start here.

Attention: You have to be familiar with Tasmota, MQTT, IOBroker (or similar), Zigbee (or similar), basic wiring and soldering! This is definitely nerd stuff and not for the average Tesla driver out there, you’ll need some kind of insanity to complete this tutorial 😉
