The Z-Wave Sensor CS driver supports the indoor version of the Ring Z-Wave Gen 2 contact sensor. @csstup can probably add this fingerprint, but I don’t know if it will provide the functionality you need. For the indoor version, the driver supports contact sensor status, button status, tamper alert, battery level, and Z-Wave network ID.
I presume that the outdoor version of this sensor is backwards compatible with older Z-Wave versions since there is no ST hub that supports Gen8/Z-Wave LR.
