OLA trigger config to control Philips Hue color lights with DMX (Art-Net, sACN or via DMX input)

This is not the most elegant solution but it works though and the color conversion from RGB to CIE1931 is not perfect.

Please note that the Hue bridge has some frame rate limits.
SyntheFX has a good article regarding Philips Hue response times vs. DMX.

This config also works with the deCONZ API from Dresden Elektronik (does not support HTTPS at the moment though)

Requirements

• OLA
• Node-RED
• HueMagic for Node-RED
• curl
• jq
• Philips Hue bridge alternatively a gateway from Dresden Elektronik

Installation

• Download the rgbhue.conf and edit the configuration section
• Download the rgbhue.sh shell script, place it in the same directory and make it executable with chmod +x
• Download the rgbhue_flow.json file, import it into Node-RED and edit the Hue bridge settings
