When they were not showing up in Hubitat and would not join. They were likely still connected as a ghost device.
but if you connected the Xbee3 to the computer and ran XTCU. In the top right corner select "switch to network working mode" and then slect "scan".
As a ghost device you would see a bunch of devices connected.
If it was not connected to any network only the Xbee3 itself would appear.
Glad you got it going.
Once setup correctly they are pretty solid.
I recently moved 2 Xbee3 routers and 2 Xbee3 end devices from my C-3 hub to a new networked C-5 hub to run in a multi hub setup with no issues.
