SmartThings Motion Sensor Trigger

Sorry I'm thick, but I can't figure out how to trigger something like a like with a motion sensor. Do I check the status like every second with an interval or does it somehow send it from smartThings to node-red.

How is smartthings connected to node red? Are you using a contrib node? If so which one (node-red-contrib-something)?

I'm using this one. https://flows.nodered.org/node/node-red-contrib-smartthings

I got it to work, I noticed the debug link and worked through that. I made sure everything was set to local using the full URL with port. Then the http request node and started getting updates.
