ZWave Issues with Warranty Hub

[jtp10181]

How is your C8 being powered? Sorry if this was asked before but I did not see it.
If not the OE supplied power block, you need to test with that for a baseline.

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.

• 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)
• Provide screenshots showing entire Z-Wave details Page
• Provide screenshot of Z-Wave Topology Map (red/blue squares)

Also, all of those nodes with the "Discover" button need to be removed.

Simple first steps - try these first

1. If a Discover button appears for a partially included device, selecting that button can allow a device to successfully complete joining the Z-Wave mesh.
2. Shut down the hub and restart it to force restarting of the Z-Wave radio - this can help w/ghost issues:
   -- a. Shut down your hub from the Settings menu.
   -- b. Then pull the USB power plug (recommended to do at the wall connection, not at the hub as the hub connection can be a little fragile, at least on some C-7 hubs) to completely remove power from your hub after it's shut down.
   -- c. Wait 30s
   -- d. Plug the hub in again.

Using the hub's built-in ghost removal tools
Below is a detailed summary from @jtp10181 of best way to use the hubs built-in ghost removal tools. Try these tools first before trying Ghost removal with a UZB stick:

• Click Refresh on the device ONCE, wait for the page to refresh. The Remove button should then appear. Click Remove ONCE. Again, wait. May want to have logs open while doing this as well.
• Sometimes it takes multiple tries of the Refresh button to get the Remove button to appear. Try to be patient and NOT click Refresh furiously. If you start getting "Zwave busy" error messages in your logs, power down and reboot again.
• It is common for it to take multiple tries at the Refresh/Remove buttons to remove a ghost, give it at least five or six attempts before assuming it's not going to work. Shutting down/restarting between successful removals can also help.
