I think it should at least be able to pair with the hub using the stock z-wave motion sensor handler. Custom device handlers can add additional functionality.
Sometimes even brand new z-wave devices need to be excluded before they can be paired to a z-wave controller. Put the hub in general device exclusion mode, then follow the instructions that come with the monoprice sensor for excluding it from a controller. Then try pairing again.
Yeah… it took me about 3 days to figure that out, too. I think the installation guide needs a picture!!

Yeah it’s a little tricky at times, here’s a guide (should add pictures to it)
INCLUSION INSTRUCTIONS: It is recommended to install the Device Handler BEFORE paring the device for easier setup. To pair the device, Select Add New Device from the MarketPlace on your ST phone app. Then open the motion sensor device cover. Push a pin into the little hole behind the sensor and press it a couple of times. The close the cover after it shows up. If you’re doing an inclusion after an exclusion, remove the battery first and then reinsert it and then follow the above instructions, otherwise the device doesn’t always pair up.
