First time using an RGBW controller (Fibaro FGRGBWM-441) and a RGBW led strip and i'm fairly new to domoticz, so bear with me

Let me start with saying that the setup i bought, fibaro and led strip, should work with Domoticz according to the seller.
The problem is that the led strip is only showing red colors, when i pick another color the lights go out. I can dim the red light but thats it. When i pick the green color I can see it light up a little but its bareley there.
I think it has something to do with the configuration but i'm absoluty not sure, anyone who can help me out?
I'm using domoticz V3.8153 on a Raspberry pi with Z-wave module.
