WLED Wake up light

Third party integrations
1

Good morning guys,

I’m trying to build a wake up light using an ESP8266 with WLED, and a WS2812 LED strip. I have the WLED strip talking with Home Assistant and everything is working as expected.

My problem is that all the automations/scripts I find rely on the transition time. And WLED only supports transition times up to 60 seconds.

Do any of you guys have an idea as to how a wake up light could be implemented with WLED?

You could implement a while loop that increases the brightness slightly and has a delay in the loop as long as you like. You could increment the colour temperature in the same loop.

3

Look at the night light feature, I could be wrong but I believe it can be made to turn the light on to X brightness slowly over a long time frame from fully off.

4

I will look into that later today. Think you are right. The night light mode can be inverted to work as a sunrise feature.

5

So, partial succes. If I activate the night light feature from the wled web interface it works! Makes a great sunrise. But if I activate it from the home assistant wled night light switch, it skips the fade in part of the sunrise :sun_with_face:.

- while: "{{ repeat.index < 255 }}"
  sequence:
    - service: light.turn_on
      data:
        entity_id: light.your_light
        brightness_step: 5
    - delay: 60

This will increase the brightness by 5 every minute until 100% (255). This takes 51 minutes. Feel free to adjust the delay or step values. e.g. 30s delay gets you full brightness in 25.5 minutes.

For a more realistic sunrise that starts as an orangy light and progresses to a bright blueish white you could adjust the colour temperature at the same time:

- service: light.turn_on
  data: 
    entity_id: light.your_light
    brightness: 5
    color_temp: 2500
- delay: 60
- while: "{{ repeat.index < 255 }}"
  sequence:
    - service: light.turn_on
      data:
        entity_id: light.your_light
        brightness_step: 5
        color_temp: "{{ state_attr('light.your_light', 'color_temp')|int + 69 }}"
    - delay: 60

With a step size of 5, 255/5 = 51 steps.
51*69 =~ 3500.
2500 + 3500 = 6000

So the color temperature goes from 2500 to 6000 as the brightness increases.

Thanks! Looks really good. But i’m really after the sunrise effect that WLED has.

But i think I might have it nailed. Instead of toggling the night light button, I call the sunrise effect. The speed I set then defines the wake up time.

So the code below gives me a 5 minute sunrise.

action:
  - service: wled.effect
    entity_id: light.soverum
    data:
      effect: Sunrise
      speed: 5
mode: single

Invalid config for [automation]: [while] is an invalid option for [automation]. Check: automation->action->2->while. (See ?, line ?).

  action:
    - service: light.turn_on
      data:
        brightness_pct: 20
        entity_id: light.rom1
    - delay: 60

Compare the documented syntax to your attempt. https://www.home-assistant.io/docs/scripts#while-loop

None of your attempts are following the exapmle laid out in the documents:

      - repeat:
          while:
            - condition: template
              value_template: "{{ repeat.index <= 20 }}"
          sequence:
            - service: script.something

Thank you very much :grinning: Now working fine.

This is exactly what I am looking for. But I can’t get this to run on my HomeAssistant as an Automation. Do I need something special to get the service “wled.effect”? It is not avaiable for me.
WLED is already integrated into HomeAssistant. I am using D1 mini with an WS281B LED stripe (120 LEDs).

Error message:

Error running action
Unable to find service wled.effect

I tried to edit the automation yaml, but it was not working :frowning:

This is how I did it

action:
  - service: light.turn_on
    target:
      entity_id: light.wled_2
    data:
      effect: Sunrise
  - service: number.set_value
    target:
      entity_id: number.wled_intensity
    data:
      value: 155
  - service: number.set_value
    target:
      entity_id: number.wled_speed_2
    data:
      value: 3
mode: single
