RFXCOM Setting up China motion Sensor

I have my RFXCOM Transceiver connected in OPENHABIAN running on a RP2. In the Devices I have the transceiver setup and apparently working. I have some inexpensive motion sesnors form china that I am trying to add to Openhab. These will be my first non-network devices in OH2.

In the log file tail output in Openhab, I see the RFXCOM433trx capturing the motion sensor output form my two devices (id’s 853500, 323212)

These are simple motion sensor devices that the Openhab plugin is detecting as Lighting controls. How can I submit this to be fixed in the Binding and also how do I set these up to work as motion sensing devices?

There is NO documentation with these devices nor a recommended gateway or protocol available.
