Hi, I would like to use my Sonoff basic for controlling the garage door.
To be able to do that, I need to short a signal line coming from and back to the motor.
The only idea I have is to cut the mains connection coming to the relay on the Sonoff and use the relay for switching. Also I would need to flash the firmware, because there is no known way of controlling the Sonoff for such short periods.
I have no problems with voiding the warranty.
Thanks a lot!
