|
.. warning::
|
|
|
|
NeoPixelBus does **not** work with ESP-IDF.
|
|
|
|
For clockless lights, you can use :doc:`esp32_rmt_led_strip`, and for SPI LEDs see :doc:`spi_led_strip`.
|
|
|
|
|
|
The ``neopixelbus`` light platform allows you to create RGB lights
|
|
in ESPHome for individually addressable lights like NeoPixel or WS2812.
|
|
|
|
It is very similar to the :doc:`fastled` platform.
|
|
In fact, most addressable lights are supported through both light platforms. The
|
|
difference is that they use different libraries: while the fastled platform uses
|
|
the `FastLED <https://github.com/FastLED/FastLED>`__ library, this component uses
|
|
the `NeoPixelBus <https://github.com/Makuna/NeoPixelBus/>`__ library internally.

|
- platform: neopixelbus
|
|
type: GRB
|
|
variant: WS2811
|
|
pin: GPIOXX
|
|
num_leds: 60
|
|
name: "NeoPixel Light"
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
**Base Options:**
|
|
|
|
- **name** (**Required**, string): The name of the light.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
- **num_leds** (**Required**, int): The number of LEDs attached.
|
|
- **effects** (*Optional*, list): A list of :ref:`light effects <light-effects>` to use for this light.
|
|
|
|
**Type Options:**
|
|
|
|
- **type** (*Optional*, string): The type of light. This is used to specify
|
|
if it is an RGBW or RGB light and in which order the colors are. Defaults to
|
|
``GRB``. Change this if you have lights with white channel and/or the colors are in the wrong order.
|
|
- **variant** (**Required**, string): The chipset of the light.
|
|
|
|
The following options are supported:
|
|
|
|
- ``800KBPS`` (generic option, recommended for chipsets without explicit support)
|
|
- ``400KBPS``
|
|
- ``WS2811``
|
|
- ``WS2812``
|
|
- ``WS2812X``
|
|
- ``WS2813``
|
|
- ``SK6812``
|
|
- ``TM1814``
|
|
- ``TM1829``
|
|
- ``TM1914``
|
|
- ``APA106``
|
|
- ``LC8812``
|
|
|
|
Additionally the following two-wire chipsets (set ``data_pin`` and ``clock_pin``)
|
|
are supported:
|
|
|
|
- ``WS2801``
|
|
- ``DotStar``
|
|
- ``LPD6803``
|
|
- ``LPD8806``
|
|
- ``P9813``
|
|
|
|
- **method** (*Optional*, string): The method used to transmit the data. By default, ESPHome will try to use the best method
|
|
available for this chipset, ESP platform, and the given pin. See :ref:`methods <neopixelbus-methods>` for more information.
|
|
|
|
- **invert** (*Optional*, boolean): Invert data output, for use with n-type transistors. Defaults to ``no``.
|
|
|
|
**Pin Options:**
|
|
|
|
Some chipsets have two data pins to connect, others only have one.
|
|
If you have one line, only specify ``pin``, otherwise specify both ``clock_pin`` and ``data_pin``.
|
|
|
|
- **pin** (**Required**, :ref:`config-pin`): The pin for the data line of the light.
|
|
- **clock_pin** (**Required**, :ref:`config-pin`): The pin for the clock line of the light, for two-wire lights.
|
|
- **data_pin** (**Required**, :ref:`config-pin`): The pin for the data line of the light, for two-wire lights.
|
|
|
|
**Advanced Options:**
|
|
|
|
- All other options from :ref:`Light <config-light>`.
|
|
|
|
.. warning::
|
|
|
|
On ESP8266 it's highly recommended to connect the light strip to pin
|
|
GPIO3 to reduce flickering.

Methods
|
|
-------
|
|
|
|
NeoPixelBus supports different methods to transmit the pixel data to the light strip depending
|
|
on the chipset, ESP platform and pin.
|
|
|
|
Each of these has their own advantages/disadvantages regarding stability and speed. By default
|
|
ESPHome will choose the best one that is available on the device. However, you can override this
|
|
by manually supplying the ``method`` option.
|
|
|
|
.. code-block:: yaml
|
|
|
|
light:
|
|
- platform: neopixelbus
|
|
# ...
|
|
method:
|
|
type: esp8266_uart
|
|
bus: 0
|
|
async: false
|
|
|
|
Use the ``type`` configuration variable to select the method used. The additional configuration
|
|
settings vary by method:
|
|
|
|
- **bit_bang**: The simplest method and available on all platforms. However, it can produce quite a bit of flickering,
|
|
and so is not recommended for use. On ESP8266, supports pins GPIO0-GPIO15, on ESP32 pins GPIO0-GPIO31.
|
|
|
|
- **esp8266_dma**: The recommended method for ESP8266s. Only available on pin GPIO3.
|
|
|
|
- **esp8266_uart**: An alternative method for ESP8266s that uses the UART peripheral to send data.
|
|
Available on pin GPIO1 for bus 0, and GPIO2 for bus 1. Additional options:
|
|
|
|
- **bus** (*Optional*, int): The UART bus to use. If 0, the logger ``baud_rate`` option must
|
|
be set to 0 and logs over USB/serial won't work.
|
|
- **async** (*Optional*, boolean): Use an asynchronous transfer. Defaults to ``false``. If enabled,
|
|
the logger must be disabled even if bus 1 is used.
|
|
|
|
- **esp32_i2s**: The recommended method for ESP32, but not available on the ESP32-S3 or ESP32-C3.
|
|
Available on all output pins. Additional options:
|
|
|
|
- **bus** (*Optional*): The I2S bus to use. The ESP32 has bus 0 or 1 available, but the ESP32-S2 only bus 0.
|
|
One of ``0``, ``1``, ``dynamic``.
|
|
|
|
- **esp32_rmt**: An alternative method for ESP32 that uses the RMT peripheral to send data.
|
|
Available on all output pins. Additional options:
|
|
|
|
- **channel** (*Optional*): The RMT channel to use. The ESP32 has channels 0-7, ESP32-S2 0-3, ESP32-S3 0-3, and ESP32-C3 0-1.
|
|
Defaults to 6 on ESP32, and 1 on other ESP32 variants.
|
|
|
|
The following method is available only for two-wire chips (specify ``data_pin`` and ``clock_pin``):
|
|
|
|
- **spi**: Uses the hardware SPI interface to transmit the data. Available on both ESP platforms.
|
|
Additional options:
|
|
|
|
- **bus** (*Optional*, string): On ESP32s the SPI bus to be used can be selected. One of ``vspi`` and ``hspi``.
|
|
- **speed** (*Optional*, int): The frequency to send data with. Defaults to ``10MHz``. One of
|
|
``40MHz``, ``20MHz``, ``10MHz``, ``5MHz``, ``2MHz``, ``1MHz``, ``500KHz``.
|
|
|
|
On ESP8266 only GPIO13 can be used for ``data_pin`` and only GPIO14 can be used for ``clock_pin``.
|
|
|
|
The ``method`` key also accepts a short-hand syntax consisting of a single value for historic reasons. Usage of
|
|
this method is no longer recommended, but documented here for reference purposes. Possible values were:
|
|
|
|
- ``ESP8266_DMA`` (for ``esp8266_dma``)
|
|
- ``ESP8266_UART0`` (for ``esp8266_uart`` on bus 0)
|
|
- ``ESP8266_UART1`` (for ``esp8266_uart`` on bus 1)
|
|
- ``ESP8266_ASYNC_UART0`` (for ``esp8266_uart`` on bus 0 with async enabled)
|
|
- ``ESP8266_ASYNC_UART1`` (for ``esp8266_uart`` on bus 1 with async enabled)
|
|
- ``ESP32_I2S_0`` (for ``esp32_i2s`` on bus 0)
|
|
- ``ESP32_I2S_1`` (for ``esp32_i2s`` on bus 1)
|
|
- ``BIT_BANG`` (for ``bit_bang``)
