LIFX Light Automation help

I have a LIFX lightbulb. Using the integration the light does turn on and off when I click the entity slider.
But the automation I am attempting to use does not seem to work. Though it does send the message that the Outdoor lights turned on at the correct time.
I started off by having it turn on at a set time but it will not do it. My ultimate goal is to have it turn on at sunset and a reverse automation to turn off at sunrise. Here is the yaml I have.
What am I missing
Thanks

  trigger:
    # platform: sun
    # event: sunset
    - platform: time
      at: "06:15:00"
  action:
    - service: light.turn_on
      entity_id: light.garage_south
    - service: notify.telegram_carlton
      data:
        message: "Outdoor lights turned on"
  mode: single

Try this instead:

    - service: light.turn_on
      entity_id: light.garage_south
      brightness: 255

I found that sometimes my lights would be “turning on” but with a brightness of 0 if I didn’t include the brightness data.

Thanks for the suggestion but does not work for me. Your code gave me an error “Property brightness not allowed”
I have no clue why not.
I used some of the automatons on line and even read the post about your light sequence to see if I could gather any data.
But nada.
Appreciate the help.

Ah, I think I’ve found the problem. LIFX doesn’t support the normal light.turn_on service call for most actions. Full details here but in the mean time you could try:

    - service: lifx.set_state
      entity_id: light.garage_south
      power: true
      brightness: 255 #maybe optional?

Again thanks for the assistance.
Since it is still not working even after copying the LIFX examples from the link, there has to be something else wrong. I will plug away at it but still very frustrating.

Brightness should be under data, this turns my lifx on full brightness at sunset.

alias: On at sunset
description: ''
trigger:
  - platform: sun
    event: sunset
condition: []
action:
  - service: light.turn_on
    entity_id: light.lifx_1
    data:
      brightness: 255
mode: single

I will try it and let you know.
Thank you.
