Simulaton of sunrise with Hue

Hi
I’ve been trying to simulate a sun rise with hue using a color bulb (osram RGBW). I would like to set the color temperature with to reddish/warm and increase this slowly along with brightness.
For this I send alternating commands to the color temperature channel and then to the color HSB(with node-red), but the bulb seems to jump between the temperatur mode and the HBS mode, but it kind of works.

Did any of you find a alternative solution?
