    RPi1/Zero, RPi3

    My config
    RPi B 256MB with Raspian Jessie powered via microUSB port
    WS2812b - 208 leds powered with 5 V 15 A
    USB Grabber ID 1b71:3002
    Hdmi splitter

    My hyperion.config.json

    tried with and without commented lines in device section.

    When I use ws2812b driver I get red screen of death and RPi hangs.
    The same thing is with ws281x. So I can not run it with pin 12 - GPIO18.
    I can boot with ws2812b or ws281x when I disconnect grabber then hyperion is failed to start

    I have changed driver to ws2812spi and it partialy works.
    I tried it with RPi B 256MB, RPi B+ and borrowed RPi3.

    On RPi3 it works for a while and then it generaly loosing backlight of right side of TV but I got also from time to time gap on the bottom(begin of LED string) side instead of this left side.

    With RPi B and B+ works without right side (end of LED string) what is more I got LED blinks.
    Booteffect works at start for all leds and setting color of leds from HyperCon also works for all leds.

    added to /boot/cmdline.txt line spidev.bufsiz=32768
    Finaly I would like to use Hyperion on RPi B.
    Could you please advise what I do wrong.

    Hey, i believe that everything is ok...those ws2812b leds are just sometimes a little bit tricky...to get rid of this problem without testint to much things would be to get an arduino between the rpi and the leds as a "controller"
