Custom Output
|
|
=============
|
|
|
|
This integration can be used to create custom binary and float :doc:`outputs </components/output/index>`
|
|
in ESPHome using the C++ (Arduino) API.
|
|
|
|
Please first read :doc:`/components/sensor/custom` guide, the same principles apply here.
|
|
|
|
The example below is an example of a custom float output; this custom output is essentially the
|
|
same as the :doc:`ESP8266 software PWM output </components/output/esp8266_pwm>`.
|
|
|
|
.. code-block:: cpp
|
|
|
|
#include "esphome.h"
|
|
using namespace esphome;
|
|
|
|
class MyCustomFloatOutput : public Component, public FloatOutput {
|
|
public:
|
|
void setup() override {
|
|
// This will be called by App.setup()
|
|
pinMode(5, OUTPUT);
|
|
}
|
|
|
|
void write_state(float state) override {
|
|
// state is the amount this output should be on, from 0.0 to 1.0
|
|
// we need to convert it to an integer first
|
|
int value = state * 1024;
|
|
analogWrite(5, value);
|
|
}
|
|
};
|
|
|
|
// Custom binary output, for exposing binary states
|
|
class MyCustomBinaryOutput : public Component, public BinaryOutput {
|
|
public:
|
|
void setup() override {
|
|
// This will be called by App.setup()
|
|
pinMode(5, OUTPUT);
|
|
}
|
|
|
|
void write_state(bool state) override {
|
|
digitalWrite(5, state);
|
|
}
|
|
};
|
|
|
|
(Store this file in your configuration directory, for example ``my_output.h``)
|
|
|
|
And in YAML:
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
esphome:
|
|
includes:
|
|
- my_output.h
|
|
|
|
output:
|
|
- platform: custom
|
|
type: float
|
|
lambda: |-
|
|
auto my_custom_float_output = new MyCustomFloatOutput();
|
|
App.register_component(my_custom_float_output);
|
|
return {my_custom_float_output};
|
|
|
|
outputs:
|
|
id: custom_float
|
|
|
|
- platform: custom
|
|
type: binary
|
|
lambda: |-
|
|
auto my_custom_binary_output = new MyCustomBinaryOutput();
|
|
App.register_component(my_custom_binary_output);
|
|
return {my_custom_binary_output};
|
|
|
|
outputs:
|
|
id: custom_binary
|
|
|
|
Configuration variables:
|
|
|
|
- **type** (**Required**, string): The type of output. One of ``binary`` and ``float``.
|
|
- **lambda** (**Required**, :ref:`lambda <config-lambda>`): The lambda to run for instantiating the
|
|
output(s).
|
|
- **outputs** (**Required**, list): A list of outputs to initialize. The length here
|
|
must equal the number of items in the ``return`` statement of the ``lambda``.
|
|
|
|
- All options from :ref:`Output <config-output>`.
|
|
|
|
See :apiclass:`output::BinaryOutput` and :apiclass:`output::FloatOutput`.
