Component/Hub
|
|
-------------
|
|
|
|
The SM16716 component represents a SM16716 LED driver chain
|
|
(`SM16716 description <https://github.com/sowbug/sm16716/blob/master/SM16716%20Datasheet%20%5BChinese%5D.pdf>`__,
|
|
`SM16716 description <https://github.com/sowbug/sm16716/blob/master/SM16716%20Datasheet%20%5BChinese%5D.pdf>`__) in
|
|
ESPHome. Communication is done with two GPIO pins (MOSI and SCLK) and multiple
|
|
driver chips can be chained. It is used in some smart light bulbs:
|
|
|
|
- Feit Electric A19 Smart WiFi Bulb
|
|
- Merkury Innovations A21 Smart Wi-Fi Bulb
|
|
|
|
To use the channels of this components, you first need to setup the
|
|
global ``sm16716`` hub and give it an id, and then define the
|
|
:ref:`individual output channels <sm16716-output>`.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
sm16716:
|
|
data_pin: GPIO14
|
|
clock_pin: GPIO4
|
|
num_channels: 3
|
|
num_chips: 1
|
|
|
|
# Individual outputs

|
|
- platform: sm16716
|
|

|
|
channel: 1
|
|

|
|

|
|

|
|
|
|
Configuration variables:
|
|
************************
|
|
|
|
- **data_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The pin used for MOSI.
|
|
- **clock_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The pin which SCLK is
|
|
connected to.
|
|
- **num_channels** (*Optional*, int): Total number of channels of the whole
|
|
chain. Must be in range from 3 to 255. Defaults to 3.
|
|
- **num_chips** (*Optional*, int): Number of chips in the chain. Must be
|
|
in range from 1 to 85. Defaults to 1.
|
|
- **id** (*Optional*, :ref:`config-id`): The id to use for
|
|
this ``sm16716`` component. Use this if you have multiple SM16716 chains
|
|
connected at the same time.

Output
|
|
------
|
|
|
|
The SM16716 output component exposes a SM16716 channel of a global
|
|
:ref:`sm16716-component` as a float output.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
sm16716:
|
|
data_pin: GPIO14

|
|
num_chips: 1
|
|

|
id: output_green
|
|
channel: 1
|
|
- platform: sm16716
|
|
id: output_blue
|
|
channel: 2
|
|
|
|
Configuration variables:
|
|
************************
|
|
|
|
- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
|
|
- **channel** (**Required**, int): Chose the channel of the SM16716 chain of
|
|
this output component.
|
|
- **sm16716_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the
|
|
:ref:`sm16716-component`.
|
|
Use this if you have multiple SM16716 chains you want to use at the same time.
|
|
- All other options from :ref:`Output <config-output>`.

Feit Electric A19 Smart WiFi Bulb
|
|
---------------------------------
|
|
|
|
This component can be used with a version of a Feit Electric A19 smart light bulb. You can use
|
|
tuya-convert to flash the bulb. The cold white LEDs are connected to PWM1 and the
|
|
warm white LEDs are connected to PWM2. The RGB LEDs are connected to a SM16716
|
|
chip that is connected to GPIO4 for clock, GPIO14 for data, and GPIO13 for power.
|
|
A complete configuration for a Feit Electric A19 looks like:

.. note::
|
|
|
|
The white LEDs are much brighter than the color LEDs and will fully overpower
|
|
the set color when the white level is set even a little bit high. You will need
|
|
to set the white level to 0 in order to get usable colors from this bulb.
