Shelly integration RGBW2 White Channel

Hi,
I’ve a RGBW2 Controler from Shelly with a RGBWW strip, but I cannot setting it up to turn on the White chanel of the stripe from a sript. Can anyone help, please?
Here´s my script:


script:
  rgbw_turn_on:
    alias: Fita Led On
    sequence:
       - service: light.turn_on
         data:
           entity_id: light.shellyrgbw2_811b2a
           brightness: 255
           rgb_color: [0, 0, 0]
           white_value: 128

Ok, I found the solution.

If anyone having the same issue, here’s my scripr

script:
  rgbw_turn_on:
    alias: Fita Led On
    sequence:
       - service: light.turn_on
