What Hubitat model and firmware do you have?
Edit: I see now from the title of your post that you have a C-5. That may be your problem, because I believe, as reported by Bryan Copeland, that the Ring Gen 2 devices need to be paired S2, which the C-5 cannot do.
What security level do you have them paired at?
Here’s why I ask:
I personally found S2 pairing necessary to get my six Ring Alarm Range Extender v2 devices to report battery/mains status. There are some in this forum who have vehemently argued whether this point is true, but my experience matches what Bryan Copeland has reported.
