RGB control via Domoticz

[lumajo]

Hi all,
i have connected three gpios to three MosFet controlling the RGB lines of a RGB LED. with PWM setting I can control all colors quite nicely.
However, I do not fully understand how to connect the whole system to native domoticz now, using the RGB device which can be selected.
Has someone done this already and can provice some hint how to do this?
I just like to set the color through domoticz like for example the Z wave Fibaro RGB or even the Hue devices.

Many thanks
Jo
