Trouble pairing Schlage RS200HC motion sensor

Just like the subject says. I’ve tried to connect using the exact device (Motion Sensors -> Schlage Motion Sensor) and the generic one (Connect New Device). It’s not a range issue–I’ve got the motion sensor literally right next to the hub.

Anything else I can try? Any diagnostics available?

This is weird. It finally paired, but SmartThings thought it was a door sensor, not motion.

Edited to add: I have two of them, and now they are both doing the same thing: I can get them paired, but SmartThings thinks they are door sensors, and always Open. The motion detect functionality doesn’t work at all, maybe not surprisingly.

The guys at support helped me. They couldn’t explain the bad pairing, but they pointed out I could change it through the web interface and that worked fine.
