Tunable White - Preset Tuning Selection from Script/Automation?

[spooonylove]

I'm tackling my first HomeAssistant automation since i've started my setup this month: Tunable white lightbulbs on a time-based automation.

I've had success at toggling On/Off my two first Wiz lightbulbs with light groups and a basic automation. Woo-hoo!

Problem: I have not determined how to set tuned white color schemes in automations or scripts. FYI, cross-posted to reddit.com/homeassistant/

I have successfully added light switches to my lovelace interface, and when i click on the entity name, it brings up a pop-up with additional controls for brightness, color temperature, and effect.

The Effect selection allows me to use preset color temp/ brightness settings. Very handy. Further, the pre-populated list matches the options available in the Wiz proprietary mobil app.

I would like to use the same preset options available under the effect option. I have scoured the Wiz_Light GitHub repository, looking for any mention of any of the preset names i find under the drop down. I haven't found mention of "cozy", "night light", or any other preset. After looking through the custom_components/wiz_light/light.py file, I see reference to inherited features from base HomeAssistant light components. Perhaps these presets are found somewhere inside HomeAssistant code? I've searched there too, and can't figure it out.

Regardless of where the presets reside, I'm trying to simply turn on the light, and tune the white color according to a preset thats already available from a dropdown list in homeassistant.

I've tried something as simply as:

- id: '1234567890'
  alias: Living Room Night Light Mode
  description: Turns light into nightlight mode at 11pm
  trigger:
  - platform: time
    at: '23:00:00'
  condition: []
  action:
  - service: light.turn_on
    target:
      entity_id: light.family_room_lights
    data:
      effect: cozy
  mode: single

Apparently my attempt to throw a name at "effect" in the data: field isn't sufficient. It could be a simple error. Regardless, I've learned a lot so far on this first project!!

Answer!

A friendly redditor assisted me by directing me to the Home Assistant Developer - States tab, and recommending i look at the listed attributes of a given entity. Per the screenshot below my long-desired "list of presets" is there for the entity. Further, it looks like I was very close in my original code (case sensitive attributes).

Anyway, I've included a screenshot of the developer State tab, for others to take a peek at.

Final functional script:

living_room_lights_night_light_mode:
  sequence:
  - service: light.turn_on
    target:
      entity_id:
      - light.bulb200
      - light.bulb201
    data:
      effect: Night light
  mode: single
  alias: Living Room Lights - Night Light Mode

Thanks for a awesome project supporting the Wiz family!

This is exactly what I am looking for, where did you add the script?

[spooonylove]

I have the above script, and an additional one for "bright mode", both located in a scripts.yaml file in my /config/ directory.

My main configuration.yaml file has the following line:
script: !include scripts.yaml

The script can be invoked from a basic button card added on the dashboard.

As shown in the screenshot, I selected the action as "Call Service". Then, under service, simply enter a portion of your script name. It'll find it out of the millions of possible items in the list.

Before you get to dashboard integration, or time-based automation, you can go to Configuration->Scripts page on your homeassistant.local, and exercise the script to verify its working. Double check your log when you edit your configurations to make sure they are still kosher. I ended up restarting my server a couple times to get everything working properly. Please keep in mind, this is the first real functional thing i've implemented on HA.

Thank you for the assistance.. I was able to get the script working with the effects.. I really wanted to customize each light. But I havent been able to uses my own RGB color settings.. if anyone has gotten that to work please let me know how..

Not all wiz bulbs support full color. If you have the tunable white bulbs, they only have the color temperature option, as it shows in the "supported_color_modes"
