Support 3rd party Z-Wave Plus Recessed Door/Window Sensors. Allows for concealed and cleaner installation for doors (main entry doors, or service doors). Another option would be to support the GE Enbrighten Z-Wave Plus Smart Door Sensor that attaches to the door hinge. Both of these solve mounting issues with the normally supplied Ring contact sensor with door gaps, and molding issues.
Ring could rebrand and certify an existing z-wave sensor.
this is standard with most alarm systems.
