I am using my Pi 3 running OpenElec mainly as a media player with Kodi. I don't usually stream content on the Internet but either play off a local share directly using Kodi or more recently, streaming from a local Plex server using the KodiPlexConnect addon for Kodi.
Ideally I would just use my TV remote (the Pi is connected to the TV via a HDMI bug, Receiver and then TV) but that chain seems to break the CEC connection so I end up having to use a wireless keyboard which is not ideal.
Looking around for an IR solution led me to look at these type of units.
Looks like it should work as it just emulates a wireless keyboard. I am currently using a Logitech wireless keyboard but that is 2.4GHz I think since there is no IR and it connects via USB. What do GZ'er think? Then the remote can be learnt but a universal one to make it even easier again.
