As a new user, I am sharing how I added this new LR version of the lock to the C8 Pro platform 2.4.0.151.
Beginning by adding lock code manager app to Hubitat. If you plan to bridge to Apple Homekit, also add Homekit integration app:
Apps>+Add App>Lock Code Manager
Apps>+Add App>Homekit Integration
Place the lock in pairing mode and add device as a generic zwave lock:
Devices>+Add devices>Find by brand>Kwikset>Kwikset connect 620>Add
Devices>[your-device-name]>Device Info>Type>Generic ZWave Lock
If you plan to bridge to Homekit:
Devices>[your-device-name]>Device Info>Homekit enabled>Yes
This is just a basic explanation in case it helps someone else with the newest version of this lock. There may be other ways and/or other steps. I am a beginner here.
