Hi, I've been struggling to fix the issue with this ambilight system and was hoping you could help with it. System: RPi3 Arduino Uno R3 Hyperion Fushicai USBTV007 Video Grabber [EasyCAP] HDMI switcher Converter from HDMI to AV Openelec OS WS2812B LEDs (7v) (273 LEDs with leds on the corners) The sketch I am using for arduino and the config.json for hyperion are in attachment. I tested the grabber and screenshots are being taken correctly. I tested the LEDs with the arduino and they are responding as it should. Whenever I initialize hyperion the LEDs work which I think is due to the sketch code because if I set up an hyperion boot sequence it does not work. Hyperion logs don't show anything wrong (also in attachment). I try to set static colours through hyperion-remote but the LEDs do not respond. I know the Note: On grabber I am using "device" : "/dev/myframegrabber" instead /dev/video0 which is just a reference and it should be working. Problem is not with the grabber since I can't even trigger static colours through the hyperion-remote. I believe if hyperion wasn't really communicating with arduino then it wouldn't trigger the LEDs at the server initialization. Even though I am not sure what is triggering the LEDs on server initialization because hyperion bootsequences does not work. If you need anything else to be able to help me with this problem let me know. Thank you very much.
