How to control RGB LED colours via Domoticz and RPi 3 using a dimmer?

Warm welcome,

I'm trying to do an RGB LED control via RPi 3, using a dimmer from Domoticz. Is it at all possible to do this? I would like that when changing the % dimmer, the colour of the LED light changes smoothly. Alternatively, it would be sufficient for me to know if there is such a possibility in Domoticz to assign a given % dimmer to a given executable in python and what formula to use then in LUA. I am keen to control the LED directly from the GPIO of the Raspberry.

Thank you in advance for your help,
regards,
Kacper D.

As for the control itself, it certainly can be done, and probably in many ways. It all depends on how the diode is connected. Will it be connected directly to the gpio or via a driver of some kind. Will the current output from the gpio be sufficient? Because as you know, the maximum current is 17mA.

The diode would be directly connected to the GPIO. Such a current is perfectly sufficient for me. Could you drop me a reasonably simple solution? Alternatively, as I wrote, maybe you know how to create a LUA for the dimmer that would call the given executables in python?

Just as a quick what comes to mind:

Of course it needs refinement. This is only a skeleton. We write such a script in the Events menu in Domoticz. It is a dzvents script.
mojdimmer is the name of the dummy switch in domoticz. I recommend reading:
