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 Code: 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
