Connecting Existing Open/Close Sensors To New SmartThings Hub

I just figured out a way to do this using my existing sensors:

Using existing Home Security System (Honeywell, Vista, etc) Sensors with Smartthings

So like many people I have a Security System already wired into my house. Door sensors, window sensors, Motion detectors, etc. When we moved in I played around with it and figure out the code to use it; but never had any intention of hooking it up to ADT or any of the other security companies. As I’ve been getting deeper and deeper into HA, it’s always bothered me that I couldnt figure out a way to utilize those existing sensors in my SmartThings environment. Why buy new wireless motions, door sensors etc, when I already have a great setup of wired ones in place?! When browsing around for solutions, I noticed that many of the Z-wave door sensors have an external sensor port; where you can wire an external sensor into the Z-Wave sensor. My logic was, why not just use this external port …
