I updated my CoreELEC / Logitech Harmony 650 remote setup guide notes:
CoreELEC / Logitech Harmony 650 Guide
The guide covers using a Harmony 650 (or similar) with two of the most popular CoreELEC machines - Odroid N2+ and Ugoos AM6B+
In particular, with this edit, I’ve added an easy fix for those running in to issues powering on a Ugoos AM6B+ machine via their Harmony remote.
Hope it is useful for someone!
