I couldn’t find this problem reported on the forum. So in case anybody else has this problem:
When installing the Schlage FE599 into a UI7-VeraEdge system, there is no option to add that particular lock.
I tried using the one other Schlage lock which was available to add (a Schlage deadbolt), but that did not work. The lock was included but there was no lock functionality - there was no ability to lock/unlock, change pin codes, etc…
So I excluded the lock, and then I added the lock under “Generic Zwave devices”.
This seems to have worked OK.
