This is an ESPHome implementation of a 2-door garage cover that doesn't need a relay. You just have to connect the D1 and D2 pins to the buttons inside your garage door controller. I connected mine to the wall controller, but I suppose that you can use a remote. If you want to use another ESP board or other pins, make sure that you use pins that are not used by special functions or toggled at boot, otherwise your door might open when the device restart after a power outage. The sensors connected to the D5 and D6 pins are standard reed magnetic switches.
