Just getting all setup, installed hyperion.ng on a pi zero. Picture grabber all works (I can see it all working on the Hyperion config page). But my led don't light up at start up. And on the remote page I turn on the LED device and it just gets switched back off. Nothing working. I have a WS2812B strip hooked up the gpio18. I have wired up the pi and the strip to the same power supply, and I have continuity throughout the wiring. I have chosen ws218x in the device config page, and still nothing. There is nothing in the logs either. Any ideas what I've done wrong?
