I've recently setup an Adalight clone using the following:
Asus Chromebox with Ubuntu 16.10
Kodi v17.0 with Hyperion plugin
Hyperiond V1.03.2
UNO R3
218 - WS2812b LEDs
Just for reference, I've got a resistor and capacitor per the Arduino setup and a common ground between the board and lights.
I've got everything setup and running pretty well. It works with video playback and using the effects/static colors. All pixels behave normally, displaying to correct colors at the correct times as well as shut off as needed. Also all the adjustments in HyperCon/hyperion-remote work correctly. However, when I cancel any set effects and stop video playback I have a few pixels that stay lit at varying levels white. It starts this way as soon as the bootup display finishes. For right now, I use the cli to set "All Black" to all pixels at a slightly higher priority than the internal grabber. (hyperion-remote -p 876 -c 000000) That keeps all pixels shut off when no effects are running or nothing is coming from the grabber.
All pixels behave normally when connected to just the Arduino as well as with it connected to a PC as long as I don't have hyperiond running.
Aside from any obvious issues I may have overlooked, what is the behavior of hyperiond at idle and do we have any control over it?
