I have purchased the official remote control.
Unfortunately it arrived with no instructions.
I have a Raspberry Pi 3 with native bluetooth.
How can I pair the remote with the RasPi?
It’s not Bluetooth, it’s RF. Just plug in the supplied USB dongle and remove the plastic tab between the battery and the remote.
I hope you like the remote 
Ahh OK, thanks - I thought that was a bluetooth dongle - all working now!
Thanks for reporting back, I’m glad it’s all working . Thanks for supporting OSMC
Got another remote based query.
Is it possible to launch Kodi on windows, using the remote?
You would need something like EventGhost for that.
