RPi + OpenELEC hyperion.service won't start

    Hardware config: Raspi 1 + logic level converter (5V to 3,3V) + ws2812b strip
    Tested with Raspi 1 + LibreElec (v6, 7 and 8), Raspi 1 + OpenElec v8, Raspi 1 + Raspbian lite jessie, Raspi 1 + Raspbian lite stretch.
    JSON config file with device type "ws2812b" OR "ws281x" (same behaviour).

    Installed a fresh OS, installed hyperion (tested from HyperCon and also manually from terminal), sent the config file (created from hyperCon but also a manual one). Always the same behaviour.

    Result: Unable to start hyperion
    hyperion.service: Failed with result 'signal'.
    However Hyperion starts successfully when tried a config JSON with device type ws2801

    LED strip works with the same config and strandtest.py from https://core-electronics.com.au/tutorials/ws2812-addressable-leds-raspberry-pi-quickstart-guide.html

    Seems to be an issue with hyperion V1.03.4 (from April 2018) and ws2812b drivers.
    Is there any way to install a previous version of hyperion?

    Thank you
