Ring Alarm, Schlage Locks, and Hubitat Challenge!

Thread necromancy proves successful in this case. I have written this integration to control the Ring Alarm from HE.

I don't know how RM works with keypads attached directly to HE but you can control the Alarm from HE and get information and control (in some cases) devices attached to the Ring Alarm. The hurdle you will have is triggering that event off a successful code enter in HE on your HE paired keypad.
