I also am having a problem with my Yale lock with z-wave plus module. The model number for the lock is listed in the add device section but it will not sinc with the base station. Can anyone help 
Hi @Ppaw323. How close is the Base Station when attempting to add the Yale Lock? If this lock is on the Works With Ring page, it should be able to add to the Base Station. Is there are specific step that the Lock is failing at? If so, please screenshot the error you are getting and post it here. Thank you.
