|
The ``partition`` light platform allows you to combine multiple addressable light segments
|
|
|
|
|
(like :doc:`fastled_clockless` or :doc:`neopixelbus`) into a single addressable light.
|
|
|
|
|
This platform also allows splitting up an addressable lights into multiple segments, so that
|
|
|
|
|
segments can be individually controlled.

# 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**, :ref:`config-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*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
|
|
|
- **effects** (*Optional*, list): A list of :ref:`light effects <light-effects>` to use for this light.
|

|
|
|
|
|
|
|
|
- **internal** (*Optional*, boolean): Mark this component as internal. Internal components will
|
|
|
|
|
not be exposed to the frontend (like Home Assistant). Only specifying an ``id`` without
|
|
|
|
|
a ``name`` will implicitly set this to true.
|
|
|
|
|
- If MQTT enabled, all other options from :ref:`MQTT Component <config-mqtt-component>`.

.. 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.
