The RGBW2 is a full featured LED controller that supports smooth dimming of 4 channels and 16 million colors of RGB.

!BREAKING CHANGE!

With version 2022.9 the white_value is no longer an available property when you define the MQTT light entity based on the template schema.

      effect_value_template: "{{ value_json.effect }}"

Notes:

  • You need to change the <deviceId> accordingly
  • The brightness_command_template is defined in a way that if `brightness' equals to 1 that is actually 0. It is this way to be able to change gain to 0 without turning the light off (In case you only want white and no RGB).

Home Assistant to control 4 different channels of white LEDs (strips or pot lights) - For version 2022.9 and higher

The suggestion is to use one of the following integrations:
