Just curious who else may be working on this. I have been struggling with getting just the right settings to work with a harmony 650. I think having to load Microsoft Media Player and Media Player SE keyboard settings and then futz with all the settings to try to get it to control kodi the way you want it is a bit antiquated. I have been working on a Raspberry-Kodi device type and hope that logitech will pick it up and put it in their library. Then that would be all you need to install. I know, a pipe dream.
Anyone else doing anything similar? I have been moderately successful.
