How to create a Tunable white board

Configuration
1

I use a Dali KNX gateway and have a DT6 ballast with a tunable white light band. How can I build a tunable white board with the two addresses? WW and CW. So actually the same as the individual addresses in RGB, but only with tunabel white

I am not sure what you mean by “board” in this context? Do you want to be able to adjust brightness and color temperature via HA?

If yes, then just add the light as you would any other KNX light. This is how I control my LED panel (also via Dali KNX gateway, although I think DT8?)

- name: Office Ceiling
  address: "1/1/20"
  state_address: "1/4/20"
  brightness_address: "1/5/20"
  brightness_state_address: "1/3/20"
  color_temperature_address: "1/6/50"
  color_temperature_state_address: "1/6/51"

As a result I can then control it through the HA frontend:

The controller / Dali gateway has to support it (knx side; Dali doesn’t matter for us).

Individual Cw and WW addresses are not supported by the knx Integration. You can only create 2 dimmable light entities and try your luck with some template light thing or you find some integration / custom component to control them via a virtual entity.

Many thanks for your help.
I will now swap the DT6 ballast for a DT8. Then I can use the temperature address as spacegaier has described.

Be aware that the Knx-Dali-Gateway needs to have support for this too, not only the led-drivers.
If your Gateway supports this via DT6 there is no need to change the drivers.

Hi
i try to do the same. From KNX point of view it works fine - but on home assistant i´m not able to create the same card as you: the color temperature is always not showing up.
Is that a special card?

Edit: disregard the question. As soon as the first color temperatur status was updated home assistant did automatically update the card :slight_smile:
