I did the backup and restore procedure, that did not solve my problem.
I did more searches on my Jasco ZW4104 switch I was trying to add and I found a post for a different Hub that I was able to make some sense of it. Here is what I did for the ISY.
To Remove
1. Remove/Exclude a Z-Wave Device
2. Press and hold the button in the center of Lamp Module's front.
3. Plug the Lamp Module back into a outlet while holding down the button.
4. Release the button after the Lamp Module is plugged in.
5. Press release the button again
6. Press release the button a second time.
To Add
1. Add/Include a Z-Wave Device
Repeat steps 2 thru 6
Thanks for all your help. I had a better understanding on how to add a Jasco ZW4104.
