Using Enerwave ZWN-RSM1S for Garage Door Opener

Hello,

I’m currently using the MyQ app to open/close my garage. However, I want to be able to open/close it from Smarthings instead. From looking at some of the threads it looks like the common approach is to use a relay. I found a Enerwave ZWN-RSM1S relay lying around which I think should work.

I’m a newbie to all the stuff and I’m a little confused on what I need to do from the Smartthings end to get this working as momentary switch. If someone can give me some tips on how to get started I will greatly appreciate it.
