There are three key documents that you need to read first. I'm trying to locate them right now.
The main thing to keep in mind is to check after every inclusion to see that you have a device created, and that it works (from the device page). If not, STOP and remove that device before trying to include another. Doesn't hurt to reboot the hub (from settings). If you have a "ghost" from a failed inclusion, it needs to be removed before proceeding.
In order to remove failed nodes, please go to the Z-Wave Details page, then select the Refresh button for the node you'd like to remove. After the page reloads, then select Remove . Note that you may need to repeat the procedure several times for the Remove button to appear.
Here is one key document:
And another:
The third has the info given above to STOP and remove the ghost device if when you get a ghost device from a bad inclusion.
