flux++

Home Assistant custom component to let coloured lights folow the day's and circadian rythm

This is heavily based on the original Flux component in Homeassistant: https://home-assistant.io/components/switch.flux/

Improvements:

Lights that have their color changed manually will not be updated
New service 'force_update' to have all lights in the Flux++ switch which are turned on participate in the future updates again
New functionality to listen for newly turned on slights that are part of the Flux++ switch. Newly turned on lights will be updated to the flux color and participate in future updates
New conf parameter init_on_turn_on to define if newly turned on lights shall participate and be reset to the flux color or not
It is now possible to call the 'force_update' service specifying one or more entity_ids of the lights that should be updated. If no entities are given, all lights in the flux switch will be updated

Installation:

To install flux++

start_colortemp (Optional): The color temperature at the start. Defaults to 4000.
sunset_colortemp (Optional): The sun set color temperature. Defaults to 3000.

brightness (Optional): The brightness of the lights. Calculated with RGB_to_xy by default.
disable_brightness_adjust (Optional): If true, brightness will not be adjusted besides color temperature. Defaults to False.
mode (Optional): Select how color temperature is passed to lights. Valid values are xy, mired and rgb. Defaults to xy.
transition (Optional): Transition time for the light changes (high values may not be supported by all light models). Defaults to 30.

Example:

switch:
  - platform: flux++
    disable_brightness_adjust: true
    init_on_turn_on: true
    mode: mired
    transition: 300
    interval: 300
    lights:
      - light.matbord
      - light.stalampa
      - light.bank_tv
      - light.fonster_tv

Shortcomings:

This has currently only been fully tested with Philips Hue bulbs with the mired color selection mode. I would love to get feedback from others to knwo if this works with other bulb types
