Mine is connected by wire to a wall mounted opener. On the App, I click to close the up arrow on the garage unit blinks and the wall mount light turns off. I hear the relay and nothing happens. On the App, I click to open the down arrows on my garage unit blinks. (sounds backwards) Seem like the garagdget is sending the wrong signal and causing my wall mount to turn off also. I tried unwiring my wall mount and had only the garagdget. No go.
Also tried switching the wires blue to black to see if it mattered.
When i use the wall mount the light button never turns off.
Maybe my garage is too smart for garadget? The wall mount utilize only two wires to turn lights on/off, garage up/down, lock, and learn.
Garagdget needs a firmware to fix this.
