I recommend using bluetooth for a remote or at least a FLIRC. Only for wake up using IR.
I did start with IR RC6 on my Haswell NUC. That was painfull slow with my Harmony 650.
The i moved on to FLIRC with Harmony FLIRC HTPC profile, that was much faster. A FLIRC acts as a keyboard and works all the time without OS software support. But you need a windows to make firmware updates. I did an update only once as it was new and use the preprogrammed factory profiles.
Now i use a Harmony Elite with bluetooth. This is faster then my eyes, when it is scrolling.
Built in ir doesnt work well on NUC7CJYH . i basically have to be right at it for it to work. Take 2 step away and it stopped responding. i been using usb mce ir. I will look into FLIRC. thank you
