The metalab needs some new lights.

ART-net is awesome.


Raspberry Pi 3 + Touchscreen

Distro based on the QLC+ image (raspbian jessie)

QLC+ X-server less build that renders directly in GL buffers for performance

H801 based clients (ESP8266)

Arduino based firmware that implements ART-net

Temporary setup with QLC+

Connect to "metalights" WLAN


Set ARTnet uiniverse to 3

There are 5 channels / Umbrella


If CW or WW are anything else but "0" R,G and B are disabled by firmware

If R,G or B are anything but "0" CW and WW are disabled by firmware

This is to save our powersupplies from sudden heat death.
