Is anyone developing a Kevo smart lock binding?
Until Kwikset/UniKey release the Home Connect Bridge with Z-Wave and Zigbee support or an API to commuicate with the Kevo Plus IP-to-BLE bridge, I think the only option is to use the same method the Homebridge Kevo binding and pyKevo Python library uses - emulate a user using the Kevo cloud web interface.

If no one else is working on one, I may give it a try - it would be my first OpenHAB development, though.
