Sylvania osram rgbw bulb

The 2 Sylvania/Lightify bulbs are not in a group. Each bulb got the command via Advanced button control. And same issue with Rule Machine when using only one bulb only. The bulbs are connected to the Hubitat directly.
Its the Generic ZigBee RGBW Light driver/DHT

It is as if the color part of the bulbs is not working for some reason..only the Color temperature 2000-6500 range.

RM doesn't have an interface to setColor(map), and custom commands doesn't have support for Maps, passing setColor("[hue:50,saturation:50]") isn't the same as setColor([hue:50,saturation:50])

What driver is being used here?

Uses the normal [Hue Bridge Integration] and then in RM give the Hue and Saturation values.
And that is what the Sylvania/Lightify RGBW bulbs refuse to understand with the current RGBW Zigbee driver. I did some more color tests..setting hue to 100 and saturation to 100 does give it a red color. So...I do not understand what is wrong with it..will test more with a few other values of h & S.
