Issue of the topic:
I have 6 items that are in my inbox and discover file that I am trying to remove.

I have performed the following steps to try and remove the things:
sudo systemctl stop openhab.service
sudo openhab-cli clear-cache
I have removed the jsondb discovery files.
I have removed the jsondb backup discover files.
sudo systemctl start openhab.service
sudo systemctl daemon-reload

I have also used the openhab-cli to remove them from things:inbox to remove them by thingId.

They keep coming back!

Thank you for your assistance!

Z-Wave devices that reappear are zombie devices defined in the network on your controller so, from OH perspective, they exist. Too many zombie nodes can cause network performance issues. SyLabs PC Controller software for Windows can usually remove them. Some people have had some success with OpenZWave Control Panel on Linux.

Thank you very much for the information. I did not know about the SyLabs software. I was able to remove all the zombied nodes.

Note to anyone trying to remove their zombies. I used the SyLabs software. I made note of the NODES that were zombied and then shutdown my PI and plugged my USB Controller into my PC. Using the SyLabs application I then found the nodes in my controller and “-failed” them so they would be removed from the controller list. Once complete, I plugged my USB back into my PI and started it all up again.
