There’s a great project for the DIY tinkerers called RatGDO that hooks into the MyQ garage door openers and unlocks all of the feature of the app and more.

Using a ESP8266 and Home Assistant, I can open and close the door to any position, turn on and off the light, see the reading of the obstruction sensor, and lock the remotes from opening or closing the door.

There’s also some open schematics called Rat-ratgdo
