Sonoff to control garage door.
1 remotely control your door anytime and anywhere via an app on the smartphone or tablet.
3 you must set the sonoff to interlock mode so that when the garage door motor is powered to open then any power to close is disconnected.

Nodemcu esp8266 chip for door sensor.
It can turn your non smart door lock into a smart wifi door lock.
2 share access permission with anyone so that he or she will also remote lock or unlock your door.
In addition to using the sonoff sv to open and close the door i used the gpio 14 pin on the board to add the door sensor to the sonoff sv.
Much much more compact.
2 controlling a garage door motor is not that simple because the motor can be powered to open or close and must not be powered to open and close at same time otherwise the motor will be damaged.
