GE Z-Wave Smart Dimmer not responding

[jtp10181]

I would also try power cycling the switch at the circuit breaker (assuming this is a wall switch and not a plug module).

Also please read this help topic (relevant parts quoted below) and supply the requested information for further troubleshooting:

Help for Hub Related Issues

Please provide the following info (if you are not sure just say so)

All Hub Issues

• Model of Hub
• Platform/firmware on hub

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.

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
• Provide screenshots showing entire Z-Wave details Page
  • Click the Refresh Statistics button before taking screenshots
  • 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)
• Provide screenshot of Z-Wave Topology Map (red/blue squares)
