Umbrella
Version 2.0
At several Jour fixes (2022-02-22_Jour_Fixe, 2022-04-26_Jour_Fixe and 2022-05-11_Jour_Fixe) the decision was made that the Umbrellas need an upgrade. The LED strips were replaced by four IKEA Tradfri LED bulbs which are mounted on a custom lasercut aluminium plate.
How to use
anlumo knows all the things about them!
They are all mapped into our SmartLab and controllable through Zigbee via Home Assistant.
Name convention:
light.Hauptraumschirm_<row>_<column>_<index>for individual lampslight.Hauptraumschirm_<row>_<column>for individual umbrellaslight.Hauptraumschirm_<row>for rows of umbrellaslight.Hauptraumschirmefor all of them together
All numbers are 1-based. The indexes of the lamps inside umbrellas are random, but otherwise the numbering starts at 1,1 in the corner near the library and the kitchen.
Hardware
All CAD files can be found on Github: Umbrella v2
ripper knows all the things about the hardware and will add this!
ToDo: add info on hardware thats not in the Github repo
Maintenance
The bulbs are standard, Ikea TRÅDFRI RGB LED bulbs. For replacing one, the umbrella needs to be removed by pushing them upwards and moving them towards the windows.
ToDo: how to replace components/fixtures

Version 1.0
Outdated information, just here for documenting the history
This version has been replaced.
Umbrella is the ceiling lighting of the main room. It consist out of 12 umbrellas capable of emitting light in either 16581375 RGB shades or 65025 white shades.
The umbrellas are controllable with art-net.
How to simply turn on/off the light
Use the Interruttore light switch.
Access data
- WLAN SSID: metalights
- Protocol: art-net
- 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)
How to flash
- Install Arduino IDE
- Install ESP 8266 extensions
- Choose generic ESP8266 Board under Tools->Board
- Settings for ESP8266:
- GENERIC ESP8266 Module
- Flash Mode: DIO
- Flash Size: 1M (512K SPIFFS)
- Debug Port: Disabled
- Debug Level: none
- Reset Mode: ck
- Flash Frequency: 40 MHz
- CPU Frequency: 80 MHz
- Upload Speed: 115200 or more
- U need a USB-to-UART-board (set to 3.3V)
- Connect GND to GND; RX to TX(!) and TX to RX(!); DO NOT CONNECT 3.3V!
- Set JUMPER on board to boot into flash mode. (Important! Has to be set before power is connected, so board gets into flashing mode.)
- Supply power via VCC & GND (12V should be adequate)
The code to flash can be found in the github repo. If you want to flash exactly this code (and what else would you flash in the main room), you will need these libraries:
- ArtnetWifi (Has to be installed via git clone to ~/Arduino/libraries)
- WifiManager
- ArduinoJson (Version 5.13.3)
Who
Originally invented and built by overflo, the umbrellas were built by a lot of people in some night shifts at Metalab
