Rgbw zwave controller?

I have an fibaro zwave rgbw switch/relay, is there a way to get that thing in hass to work? I have only a lot of switches at the moment for that. openzwave detected it and i can set color values/brightness. But a color picker or similar like sliders for the colors would be better then switches to just set it on or off.

Just add the first entity ID to your hass config and u will see the color picker if u click on it mine looks same i guess in dev states:
