Automation to enable an effect on the Shelly Bulb RGBW

Configuration
1

Hello, i am trying to do an automation to enable an effect on the Shelly Bulb RGBW (SHCB-1). It works with assist to control the bulb to turn on and off but i dont know how to do the yaml config for the effects.

This one automation config is working correctly to turn the bulb on:

alias: lampe on
description: ""
trigger:
  - platform: conversation
    command:
      - turn the light on
condition: []
action:
  - type: turn_on
    device_id: ..............
    entity_id: ..................
    domain: light
    brightness_pct: 80
mode: single

This are the possible states for the bulb (copied from dev/states)

min_color_temp_kelvin: 3000
max_color_temp_kelvin: 6500
min_mireds: 153
max_mireds: 333
effect_list:
  - "Off"
  - Meteor Shower
  - Gradual Change
  - Flash
supported_color_modes:
  - color_temp
  - rgb
color_mode: rgb
brightness: 204
color_temp_kelvin: null
color_temp: null
hs_color:
  - 238.353
  - 100
rgb_color:
  - 0
  - 7
  - 255
xy_color:
  - 0.136
  - 0.041
effect: "Off"
friendly_name: Lampe
supported_features: 36

For example i try to add effect: “Flash” to the automation config, but this error appears “Message malformed: extra keys not allowed @ data[‘effect’]”. I think im doing something wrong with the syntax.
