Hi,

I have harmony remote with flirc, I take TV samsung profile on harmony because I havn't samsung tv and set the profile then I programmed the remote with flirc with kodi profile in the flirc app .

but on the RPI 3 B+ , one click press give me 2 click instead one in the Libreelec on Rpi , Also  , you can feel that the remote not smooth with it .

What I need to do to fix that ? 

Thanks.
