2Lame2bTrue not sure, how much testing you did, but I did a bit^^
I'm using an Odroid c2 now, which uses the same CPU as LePotato. I'm using an Arduino nano.
At first, I used the Arduino code from hyperion wiki itself, but somehow it didn't work well.
Now I'm using: GitHub - dmadison/Adalight-FastLED: Adalight with FastLED support
and it's perfect 
I only changed the Gpio Pins, and the amount and type of LEDs, and thats it.
It cointains the "Magic Word" thing as well, but it's working, so I'm not complaining.
Maybe, you need to switch from Libreelec to Coreelec, because one of the Coreelec developers made a few changes to Hyperion, so it works better with the AML CPU.
