I have been using Hyperion Classic on a Intel HTPC for a fair while now without any issues.I checked the forum and saw that NG has progressed an awful lot - I am not a coder and a complete noob when it come to Linux but I am capable enough to have gotten Hyperion Classic installed and working :).
I now have NG working and all the leds operate etc and the ambilight effect in Librelec is great.
The issue I have is that if I power off the HTPC I get the RGB sequence but no rainbow effect or any ambilight within Kodi.
The server doesnt appear to be working as I cannot connect via phone app but if I use the web gui I can manually turn the leds on.
I am using APA102 Led's and the kit I originally had was a Lightberry kit that has been modded to have more led's so it uses an Arduino.
I have messed around adding various Hyperion Kodi add-ons and was wondering if these could be interfering with the system - all uninstalled now I must add.
