Ty for this info. I'm not enough able to compile hyperion myself. Anyway, could you please point me to the correct options to use the hyperion-aml in the config files? I'm using amlgrabber atm with no success. What should i add to the config file to use the hyperion-aml code?
Original hypercon in latest version, very nice install hyperion if you just add him correct ip, login and password, for libreelec login: root password: libreelec. And remember on hypercon first you generate config file after that you choose it and send to the device. You must stop hyperion, send chosen config and start process again.
From hypercon most important settings are "device", wrongly set could be problematic, next leds, wrongly set could only lights wrong led nothing more 
next settings is too choose proper grabber, if you use as me libreelec on amlogic device and arduino device properly set, just connected to usb port.
For arduino and amlogic boxes you need use amlgrabber for hardware decoded media and framegrabber for rest and kodi gui. But if you want lights for both you must set lower number for higher priority in amlgrabber, for example 890 for framegrabber and 889 for amlgrabber. At start, i use both but i saw flickering light sometimes on movie and figure out its fault of subtitles which looks like try use framegrabber i think, i try set higher priority for amlgrabber but it not help so i remove framegrabber from my config.
Next settings is colour calibration at start i though it will be difficult but on hyperion wiki you will find very useful pictures for set all. In those settings very important is white balance and greyscale for gamma settings, default gamma is 2.5 my leds work much better on 2.0, but as i say you need set it for yourself. And as i wrote before amlgrabber work only for hardware decode media, as pictures are not hardware decoded for colour calibration you must add framegrabber
Ok so wonderiuy if you set correctly device when you connecting device to usb port you should see flashing leds which inform you that arduino work and use own start effect from sketch but just after that you should see hyperion boot effect, if you dont see it its looks like you have wrong set device in config or your config is fault for example missing comma or parenthesis.
If you see boot effect just add to your config amlgrabber for example:
"amlgrabber" :
{
"width" : 64,
"height" : 64,
"frequency_Hz" : 20.0,
"priority" : 889
},
"framegrabber" :
{
"width" : 64,
"height" : 64,
"frequency_Hz" : 20.0,
"priority" : 890
},
You could delete framegrabber to be sure it not mess in priority. But you will not have lights on pictures or kodi gui.
I try compile ng version but i cant find proper crosscompile instruction and dont have additional amlogic device to build compiler
so its not eco-friendly 
wetek hub is quite offen in their interest
