I have added the opener to smartthings without issue. The device shows when the garage door is open or closed. But when I attempt to open or close the door from the app the Iris module will sound and blink to notify of the pending action and smartthings app will say it is opening or closing but nothing happens. The garage door opener is a standard Craftsman chain drive model. I have attempted to reverse the wires just to see if changes and nothing. On the motor there is an open up arrow button (manual controls on the motor) and a down and the up will blink once and down 3 times upon either open or close attempt but nothing happens.
Model is a Craftsman 54990
