hi there, I made the ambilight with the raspberry pi 3 and ws2812b. I put the data input in rpi pin 12. Gnd to pin 6 and power supply. 5v to power supply. In hyperion I made the hardware like: Ws281x. The leds turns on but no ambilight. I read here on this forum that it is possible to use it without an arduino. Could somebody help me???
