Component/Hub

The SM2235 component represents a SM2235 LED driver chain in
ESPHome. Communication is done with two GPIO pins (DATA and CLK).
To use the channels of this components, you first need to setup the
global ``sm2235`` hub and give it an id, and then define the
:ref:`individual output channels <sm2235-output>`.
.. code-block:: yaml
# Example configuration entry
sm2235:
data_pin: GPIOXX
clock_pin: GPIOXX
max_power_color_channels: 9
max_power_white_channels: 9
Configuration variables:
************************
- **data_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The pin used for DATA.
- **clock_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The pin which CLK is
connected to.
- **id** (*Optional*, :ref:`config-id`): The id to use for
this ``sm2235`` component. Use this if you have multiple SM2235 chains
connected at the same time.
- **max_power_color_channels** (*Optional*, int 0-15): Adjusts the current supplied to the
color channels, higher is more power. Default is 2 per SM2235 datasheet. See table below.
- **max_power_white_channels** (*Optional*, int 0-15): Adjusts the current supplied to the
white channels, higher is more power. Default is 4 per SM2235 datasheet. See table below.
.. note::
The LED driver may be able to tolerate more power than
the bulb is designed to handle, start with lower values
and increase slowly, comparing to a stock bulb to verify
what is safe for your model.

.. _sm2235-output:
Output
------
The SM2235 output component exposes a SM2235 channel of a global
:ref:`sm2235-component` as a float output.
.. code-block:: yaml
# Individual outputs
output:
- platform: sm2235
id: output_red
channel: 1
Configuration variables:
************************
- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
- **channel** (**Required**, int): Chose the channel of the SM2235 chain of
this output component.
- **sm2235_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the
:ref:`sm2235-component`.
Use this if you have multiple SM2235 chains you want to use at the same time.
- All other options from :ref:`Output <config-output>`.
.. note::
This driver does support enabling of both the color and the white channels
at the same time, but it is not encourage. Therefore, the :ref:`rgbw_color_interlock`
should be set to true when using this driver for safest operation.
