Griffin PowerMate Bluetooth remote setup

Hi, does anyone have some instructions on how to setup a Powermate bluetooth remote with pi musicbox?

Is this device reporting itself as HID ? If yes I could help. I did connected this:
to my custom mopidy box. I guess pi musicbox should be the same.

I will check how I did that if I get home, pls. send me a message if I forget to.

basically you need two things, first is to make this device show in the system as input device (/dev/input/). And second is to use mopidy-evtdev plugin.
