Yale Conexis L1 Z Wave not working

Avoid using the brand name option to pair the device (esp for Yale locks) as some of them default to using a cloud connection or bridge pairing instead of the direct Z-Wave pairing which can lead to trouble and loss of features.
Instead using the Generic Z-Wave device or the Scan nearby option to pair your lock within a few ft of the hub.
