If you are looking to connect the output to Smartthings and it has no/nc contacts see the following link.

Triggering Alexa tone/notification using NO/NC relay or 12v DC output from RE-4K Plus Receiver (driveway alert system)

Use an EcoLink Z-wave tilt sensor. It has a set of contacts that can be connected to the NC/NO contacts in the the driveway controller. It shows up in ST as a contact sensor, so it can also trigger Alexa Routines. And it is less than $12.
