You don't need a device-specific driver...members on that thread are using it with the Generic Zigbee Motion Detector driver. That's the same driver you'd use w/almost any zigbee motion detector, like the Iris V2 and V3, and the SmartThings/Aeotec motion sensor, etc.
From the thread:
You should always confirm (search in the forum/post a question) if any of the Generic Zigbee or Generic Z-Wave drivers included on Hubitat will work with a device. In many (most) cases they work fine w/many devices that don't have/need custom drivers.
