Light Partition

The partition light platform allows you to combine multiple addressable light segments (like FastLED Light or Neopixelbus Light) into a single addressable light. This platform also allows splitting up an addressable lights into multiple segments, so that segments can be individually controlled.

Similarly, a single light strip can be partitioned into multiple partitions with this integration.

# Example configuration entry
light:
  - platform: partition
    name: "Partition Light"
    segments:
      # Use first LED from the light with ID light1
      - id: light1
        from: 0
        to: 0
      # Use 10 leds from light with ID light2 starting 2nd LED
      - id: light2
        from: 1
        to: 10

  # Example for light segment source
  - platform: fastled_clockless
    id: light2
    # Other settings

Configuration variables:

  • name (Required, string): The name of the light.
  • segments (Required, list): The segments this light partition controls
    • id (Required, ID): The ID of the light this segment belongs to.
    • from (Required, int): The first LED to address in the segment. Counting starts with 0, so first LED is 0.
    • to (Required, int): The index of the last LED to address in this segment.
  • id (Optional, ID): Manually specify the ID used for code generation.
  • effects (Optional, list): A list of light effects to use for this light.
  • All other options from Light.

Note

Do not use this platform to control each LED on your addressable light - the light objects have a moderate overhead and if you try to create many lights you will run out of memory quickly.

See light.addressable_set Action for that.
