Control cold / warm white with 2 individual strips - how?

Configuration
1

Hi,

some years ago I built a mirror illumination / backlight with a coldwhite / warm white strip. It is controlled with DMX via a KNX bridge, so both colors have their own KNX group addresses, therefore 2 entities are needed to control them.
I would like to create an individual light from them, so that I can control the color temperature and the overall brightness. Being still new in the homeassistant world, I have no idea how to approach this.

I found and adapted something which results in this:

light:
  - platform: cwww
    name: "WC Spiegel"
    cold_white: light.led_wc_spiegel_kalt
    warm_white: light.led_wc_spiegel_warm
    cold_white_color_temperature: 6500 K
    warm_white_color_temperature: 2700 K
    constant_brightness: false

Would that work?
However, HA complains about the missing component / integration “cwww” and I have no idea where to find it.

Hi :wave:!

This seems to be an ESPHome configuration - it is not a HA thing.

You could try to build such thing with a template_light. Have a look here Combine cool white and warm white led strip into one light - #27 by FamilyManEric - will need some adaption for your specific use case.
