Hey everyone, I wanted to share my journey of integrating Philips Hue Color Channels with OpenHAB 3. It’s been quite the adventure, and I hope my experiences can help others facing similar challenges.
I’ve been working on getting the color functionality of my Philips Hue lights to work within OH3. The switch functionality was straightforward, but the color wheel integration has been a puzzle. After hours of research, I stumbled upon a potential solution in the OpenHAB community. The idea was to use transformation scripts to handle the color data between MQTT and OH3.
I set up two transformation files, zigbeeColorIN.js and zigbeeColorOUT.js, to convert the color data formats. The input script parses the MQTT message to extract the color values and brightness, while the output script converts the OH3 color values back to MQTT format. Here’s a simplified version of what I did:
javascript
// Example input: {“brightness”:50,“color”:{“hue”:359,“saturation”:100,“x”:0.6942,“y”:0.2963},“color_mode”:“xy”,“color_temp”:158}
(function(color){
var bright = Number(color.split(/[,:]/)[1]) / 2.54;
return color.split(/[,:]/)[8] + “,” + color.split(/[,:}]/)[10] + “,” + bright.toFixed(0);
})(input)
// Convert 100% to 254 Steps of brightness
(function(color){
var bright = Number(color.split(/[,:]/)[2]) * 2.54;
return ‘{“brightness”:’ + bright.toFixed(0) + ‘,“color”:{“x”:’ + color.split(/[,:]/)[0] + ‘,“y”:’ + color.split(/[,:]/)[1] + ‘}}’;
})(input)
I configured the MQTT channels in OH3, specifying the command and state topics, and set the transformation patterns. However, despite all these efforts, the color functionality remained elusive. The UI wouldn’t update, and manual changes didn’t reflect in the system.
After reaching out to the community, I received some helpful pointers. It turns out the issue might be related to how the MQTT broker handles retained messages or perhaps a configuration oversight in the transformation scripts. I’m still tweaking the setup, but I remain optimistic.
This journey has taught me the importance of thorough testing and the value of community support. If anyone has successfully integrated Philips Hue color channels with OH3, I’d love to hear your setup details or tips!
Cheers,
