You can Check in the following document, page 47, says that remote controllers that comply with Microsoft Consumer Infrared usage models (RC-6) should work with NUCs, so you could try any (RC-6) model.
Intel® NUC6iSYB Technical Product Specification:
I use these two models; they both work just fine with all of the NUCs I have (WY, RY, SY and (brand new!) KY):
I prefer the Rosewill unit; the AverMedia unit is just a tad too small to be comfortable. The Rosewill unit came with a USB IR Receiver but I don't use it. The AverMedia unit is not RC6-compliant; I use the Generic setting for it.
A few weeks ago I bought this one for use with my NUC. 4,65 euro in the toys section of my supermarket.
Grundig RC 7 in 1.
I tried to configure it using the "auto learning" feature of the RC. No Joy. The RC came with a manual with hundreds of codes, but the print was so small I couldn't read it. I gave up.
Then, when I read this post, I picked it up again. I found the manual as an online PDF, and in the "AUX" section I found this code:
I entered 0621 into the remote, pressed the RC power button and Eureka, the NUC went to sleep. Pressed again and presto, the NUC woke up. Entered my PIN with the remote and wham I'm on the Desktop.
Second I tried it in good old MCE* which I prefer over KODI. It worked.
With one catch, I could not find the "Enter" button. With the remote, I can scroll left-right, up/down, but apparently don't have a button on the RC mapped to the enter/ACK/return function.
Perhaps someone here knows how to do that mapping manually?
