I have EcoStar door opener which seems not have direct control terminals. I mean: open circuit means command "open door" and close circuit means command "close door".
Instead, it have two terminals which which is like push button. Meaning, every close circuit is like button push. In every push button it will either start door opening/closing or stop the ongoing door operation (if on going at the circuit closing) Opening/closing will be chosed by the last operation. If last door was closed, next time it will be opened and so on.
How should I connect the Athom Garage Door opener? Is there any way to modify the code? Is it open source?
