Ok for a super simple non technical test I took a motion sensor down to my community mailbox (out of range of my mesh) approx 40 minutes ago. Just brought it home and let it sit for ~5 minutes. Then went in front of the sensor and it lit green meaning the sensor detected motion. So far no event being registered in Hubitat. I will update later this evening if it reports. This is an Iris v2 motion sensor.
[Edit]It has now checked in. Just minutes after this post. I would still suggest more research and trials to be certain this will work ok.
Also some good reading I found on the subject : How does Iris or Smartthings presence fob work? What makes them special?
