The gnashing of teeth here reads like software people trying to solve a simple hardware problem.
You don't need anyone's permission or API to control any garage door opener --- smart or dumb. The suggested "ratgo" device is one option but looks kinda overpriced to me.
Every garage door opener has 2 sets of dry contacts. One set controls the open/close function and normally connects to a physical button on the inside wall. This is easily shared with any other device. The other set is a limit switch that tells the motor to stop once the door is open. This too can be easily shared and read.
All that is required for full control is a wifi device with 1 output and 1 input that speaks Home Assistant. Sonoff or some other manufacturer must have an affordable one. If not, maybe I'll make one. It's not that hard with readily available hardware.
