Zwavejs: Z-Wave controller status has changed to Unresponsive

[jtp10181]

You mentioned reboot and shut down, did you pull power for 30 seconds so the radio will fully power off? Also how is hub being powered, see info below:

Z-Wave Issues

For partial or total loss of Z-Wave control (radio seems dead), before doing anything else please shut down the hub from settings and unplug for 30 seconds, then re-plug to boot back up. This will allow the radios to fully power down and restart. A regular reboot only restarts the platform and not the radio hardware.

What info to provide for troubleshooting assistance:

• 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

Also, since you said it works fine on ZIP, what is your actual issue with SmartStart and LR? You never said what the original problem was, just that is was a "common" problem???
