Garage Door Opener
A garage door opener controller wires into an existing opener and puts the door in Home Assistant: open, close, and where it sits in its travel, plus the obstruction sensor and the opener's own light.

ratgdo32
The ratgdo32 is an ESP32 board that wires into an existing garage opener's terminals and puts the door, the opener light, the remote lock, and the obstruction sensor into Home Assistant over the LAN. It speaks Chamberlain and LiftMaster Security+ 2.0 and 1.0 natively, or dry contact on any other opener that exposes dry contact terminals.

ratgdo32 disco
The ratgdo32 disco is the ratgdo32 with a downward-aimed laser rangefinder and a beeper added, so Home Assistant knows whether the car is in the bay and not just whether the door is open. Same wiring, same opener support, same local ESPHome project.
