@scott.sr I moved your post to a new thread.

Lets start with some basic info:

Z-Wave Issues

Confirm that hub's Z-Wave regional radio frequency matches that of your device. Check hub's region on Z-Wave Details page to ensure that is set to your local region (E.G. EU - 868.4 MHz, 869.85 MHz for European countries).

Make sure you do not have a Z-Wave firmware update available: [Instructions HERE]
The Update Firmware button is hidden when the Z-Wave firmware is already up to date.
Use http://YOUR.HUB.IP/hub/zwaveVersion to check your version info.

Z-Wave Details Page Docs: Z-Wave Details | Hubitat Documentation

How is Hub being powered? Supplied power block or other (explain)

PoE power (with splitter) is known to cause major Z-Wave issues on the C-8 hub.

See this post for detailed write up on PoE testing: PoE and the C8 (with extensive testing)
