Z-wave network failure -please help!

@njm722 Regarding below:

@rlithgow1

Those need to me removed. Click the refresh button on the device line until the remove button appears and click remove (may take a few times per device). IF you cannot remove the devices you will need a z-wave stick to remove them. Your z-wave radio is likely working fine, it's your mesh that's trashed.

More info on that process to use the hub's built-in ghost removal tools below...follow the steps exactly as listed.

Details

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.
• From some anecdotal evidence, removal of a ghost device may be more successful if the device the ghost was created from is disconnected from power while you're trying to remove the ghost. If it's a plug, you can unplug it. If it's a switch and has an air-gap, pull the air gap. You can also flip a circuit breaker to temporarily remove power from a mains powered device. I'm most cases may not help at all with removal, but an option you can consider trying.

If above doesn't work, then see section 4 of the Ghost Removal post:

How To Remove Ghosts using hub tools or a UZB Stick

The information below can help you resolve problems w/your Z-Wave mesh caused by Z-Wave device "ghosts." Section 4 of this guide and the PDF download included in it covers using a Z-Wave USB stick to remove ghosts. That section only applies to Z-Wave devices joined as "mesh" devices. Z-Wave LR devices may be joined as either Mesh or LR. If joined as LR you can't them with a secondary controller like a USB Z-Wave stick, you can only do it from the primary controller (the HE hub).
