Trouble getting Keymaster going w/ Z-Wave Lock

Hi everybody,

Following the steps in the Keymaster Wiki here, and I hit a wall: I don’t get to see my lock in the U/I for Keymaster:

as the notes say I should get a prompt and it does not apprear at all.

I did the pre-steps and the lock is a brand new Schlage BE469

Any advice?
Thanks!
