Hi there!
I recently installed Raspberry Pi OS + Kodi 18.7 + HyperionNG from scratch on a RPi3+, having happily used the old hyperion for about 2 years.
I start hyperiond from a script I call from ~/.config/lxsession/LXDE-pi/autostart. It all works quite well, even my tiny Kodi add-on to toggle the LEDs on/off and the CEC power-on/off-toggler.
I haven't looked at the CPU usage of the old hyperion, but for the NG it seems a bit high: "top" reports about 55% usage of one core. Is this normal?
Thanks!
