A couple weeks ago I noticed that Hyperion couldnt connect to the LEDs any more ("cannot connect to host" error message) but I was too busy to investigate. Today I turned everything back on and it appeared that things are working again BUT it looks like the blue LEDs no longer work.. My setup is: RP3 with the clock, digital in, and ground connected directly to the LED strip, and power (5v) + ground also connected to the LED strip by means of a 5V10A power supply. My wiring diagram looks like this: http://awesomepi.com/wp-content/upl...bilight_ws2801_raspberry_pi_howto_connect.png I also have this this switch between the LEDs and the power supply: https://www.amazon.com/gp/product/B077KX7YHH/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1 Not sure where I need to start looking, but my first instinct is that the power supply maybe damaged the LED strip because when it first stopped working I was able to get it to work again temporarily by jiggling the power cord.
Measure the voltage at the led strip. Different colour leds have differing forward voltage requirements. Blue being the highest (about 3 ish volts)
