Ahhh, I see where you are going with it. So, you want to add other Z-Wave contact/motion/[other] sensors to Ring? Yeah, as I understand it, they only allow their branded sensors to participate in the actual security functions, which makes sense from a liability aspect.
This thread might help. There are some who managed to get the Ring Security System integrated into HE, but it looks, um, convoluted.
