Qubino RGBW Flush Dimmer and control of colours via Alexa/Echo

Hi,

Does anyone have any experience of using the Qubino ZMNHWDx Z-Wave Plus Flush RGBW dimmer module?

I have set one of these up on my RPi and HA 0.59.2 and am able to turn it on/off and control colours with the colour wheel in the user interface. I also can turn it on/off and control brightness via Alexa.

But it would be great if one could change the colours as well using Alexa but I am unsure whether this is possible in any way.

Any help is appreciated, thanks
