I understand now. You want to do this all via UPB.
The UMI only responds to Link Activate commands. It doesn't do anything if sent Deactivate or other commands.
You'll need to connect the contacts of the garage door to a UMI output (e.g. pins 1&2). Connect it in parallel with the wall button.
You'll need a Link to operate the door - "Operate Garage Door"
In the "Receive Channel 1" tab, set ouput number 1 to receive the link and "Close" when it receives it.
In the "Options" menu tab set output channel 1 to momentary.
When you send the link activate the contacts close momentarily and operate the door. But it's just like pushing the button.
If the door is open, it will close. If the door is closed, it will open. If it is moving it will stop. If stopped it will reverse directions.
Is the contact wired so it is closed when the door is closed? Or the other way around?
Assuming it is wired to close when the door is closed.
Connect the contact to a UMI Contact Input. Only inputs 2 and 3 take dry contacts. (Input 2 dry contacts pins 9 & 10).
You can do the detect two ways. Using two links is probably better for automation.
One link method:
You'll need one link to signal the door status - "Garage Door Status"
Configure Input 2 to N.C. (Normally Closed).
When the door is closed, the contact has continuity.
When the door opens, the contact breaks continuity, and the UMI transmits Activate Garage Door Status.
When the door closes, the contact makes continuity, and the UMI transmits Deactivate Garage Door Status.
Two link method:
You'll need one link to signal the door open status - "Garage Door Open"
You'll need one link to signal the door closed status - "Garage Door Closed"
Configure Input 2 to Custom and select the "Garage Door Open" link for an open condition and the "Garage Door Closed" for a closed event.
When the door is closed, the contact has continuity.
When the door opens, the contact breaks continuity, and the UMI transmits Activate Garage Door Open.
When the door closes, the contact makes continuity, and the UMI transmits Activate Garage Door Closed.
It won't transmit the Closed relative link until the door is fully closed.
This won't check the door status though, so it's possible to get out of synch.
Here's a quick app guide.

You can do some more fancy things, to get a better status monitoring of the door.
I think there is a pretty good tutorial around here.
