Control RGB Leds via JSON command

[Swifty]

Hi all,

I've recently switched to Domoticz from Openhab, so still early days finding my way around the interface etc.
I'm currently trying to add my RGB lights into Domoticz, these lights are WS2801 hooked up to Hyperion software on some Pi Zero's - I can set the lights to any color via sending a JSON message to the relevant light;

{"color":[36,34,96],"command":"color","priority":100}

What I'm trying to figure out is how I tie this to the Domoticz GUI - can anyone provide some clues as to how I get an RGB 'picker' device into the 'Switches' section of the web gui, and then pass the 'picked' RGB (or on/off status) to a script which can do the JSON post?

I can probably figure out the script part, it's just how I get the picker and the values from it!

Thanks

Is this not possible? - I'd have thought interacting with devices like this would have been easy, but can't figure out how i get the domoticz gui values to a script.

I'm not sure what you mean, but this is how you change color

Code: Select all

json.htm?type=command&param=setcolbrightnessvalue&idx=YYY&hue=XXX&brightness=ZZZ&iswhite=false

XXX=color
YYY=IDX
ZZZ=Dim

You are not the only one.
Many people are searching for a "virtual Color picker" with output to the database and/or json/mqtt.
With fields like RGB(W) (#FF00FF) / hue / Brightnes.
I have tried many virtual devices, but they lack output to json/mqtt.
The colorpicker is available in Domoticz but only for some specific hardware.
Just waiting for a dev who is able and has the time to make it happen.

Here is a node-red implementation

Did anyone ever find a solution for this?
I started to learn LUA to use domoticz better. I would like to use a dummy switch to send the rgbw values to my rgbw lights.

Please help test the build linked from here: https://github.com/domoticz/domoticz/issues/2078.
With it, it should be possible to create a "Dummy" RGB/RGBW/RGBWW device, and picked color will be stored in database and accessible through JSON Web API and announced oevr MQTT.
