The umbrellas are controllable with art-net.

How to simply turn on/off the light

Use the light switch next to the kitchen. You can dim the light with the rotary knob on the side.

Host: 10.20.255.255

startUniverse: 3

There are 60 channel, 5 channels (RGBWW) per umbrella.

Why

The Metalab needed some new lights.

ART-net is awesome.

How

Raspberry Pi 3 + Touchscreen

Distro based on the QLC+ image (raspbian jessie)

QLC+ XServer 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 OUTPUT to 10.20.255.255

Set ARTnet universe to 3

There are 5 channels / Umbrella

R,G,B,WW,CW

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

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

This is to save our power supplies from sudden heat death.

(105 watt / Umbrella max)

Hardware

H801 LED controller features:

8 Mbit Storage (1 Mb)
5 channels each 45 watt max (~ 3.5 Ampere @ 12 V / channel)
