My new wireless remote Rii i7 only partial works on OSMC. On OpenELEC fully working. Please, add functionality for keys: Home, Volume Down, Back. Other keys work. Thanks. (Raspberry Pi2)
As I suspect none of the OSMC devs have this remote there is no easy way for us to do this. I would suggest that you look up on kodi.tv how to edit a custom remote.xml to customise the buttons that currently don’t do what you want.
Not all remotes can be expected to work perfectly out of the box without some customisation as there are simply too many makes and models with little standardisation of the codes for some of the less common buttons.
Try this, not sure if it will fix every button or not Volume Down / Mute key failure [SOVLED] - #4 by Dilligaf
On OpenELEC works, not IR (lirc), but 2,4 GHz radio. http://www.amazon.com/EVERSTAR®-Rii-Wireless-Keyboard-Microfiber/dp/B00J63593U
