I bought the Iris version of the Linear (GD00Z-1) and successfully connected it to my SmartThings hub at our cabin in NJ. The garage door opener is an older Sears version, (at least 6-7 year old). Works like a charm. I recently installed two new Craftsman openers and after connecting the GD00Z-1 up, linked it, and it works as expected, however, the door does not open. I put a Ohm Meter on the wires coming from the GD00Z-1, and it provides a momentary contact closure when given the close command. I thought that the wall button doe the Craftsman was a normally open contact and closes with you push it. I plan on asking my wife to push the button and check it to see if I am correct.
I can’t imagine it being normally closed and then opens when you push the button?
This setup at our other house in 20 minutes! Is this the version of garage door opener that I have that uses a backwards button?
