RF motion sensor shows as light (RFLink)

I have a new device recognised by RFLink as a light but it is a motion sensor.

I can’t find an answer how to show it as a sensor with a state like “on/off”. Now it show a slider to set it on or off. I would like to be able to trigger other events with its state.

There are two other topics about it. One says something about creating a sensor but I am not sure how to do that.

Events show up like this and would like to use the command:
got event: {‘id’: ‘newkaku_009fb000_3’, ‘command’: ‘off’}
