If you’ve got a spare garage remote control, a raspberry pi or Arduino board, a soldering iron, an optocoupler, and a sense of adventure, you can easily integrate your existing garage door opener into Home Assistant or what have you.
In fact, the Arduino starter kit comes with a few optocouplers and instructions for basically exactly this project!
Or you can get a tube of a dozen 4N25 optocouplers for like $8 on amazon.
