We need additional details, explained below. Along with some extra tips.

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.

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).

For C-7 Hub, make sure you do not have a Z-Wave firmware update: [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.

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

Hub should be running for at least 12hrs without reboot, and state how long in your post (you can find uptime on Logs > Device Stats)
