Custom Switch
|
|
=============
|
|
|
|
This integration can be used to create custom switches 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 switch; this custom switch is essentially the
|
|
same as the gpio switch implementation.
|
|
|
|
.. code-block:: cpp
|
|
|
|
#include "esphome.h"
|
|
|
|
class MyCustomSwitch : public Component, public Switch {
|
|
public:
|
|
void setup() override {
|
|
// This will be called by App.setup()
|
|
pinMode(5, INPUT);
|
|
}
|
|
void write_state(bool state) override {
|
|
// This will be called every time the user requests a state change.
|
|
|
|
digitalWrite(5, state);
|
|
|
|
// Acknowledge new state by publishing it
|
|
publish_state(state);
|
|
}
|
|
};
|
|
|
|
(Store this file in your configuration directory, for example ``my_switch.h``)
|
|
|
|
And in YAML:
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
esphome:
|
|
includes:
|
|
- my_switch.h
|
|
|
|
switch:
|
|
- platform: custom
|
|
lambda: |-
|
|
auto my_custom_switch = new MyCustomSwitch();
|
|
App.register_component(my_custom_switch);
|
|
return {my_custom_switch};
|
|
|
|
switches:
|
|
name: "My Custom Switches"
|
|
|
|
Configuration variables:
|
|
|
|
- **lambda** (**Required**, :ref:`lambda <config-lambda>`): The lambda to run for instantiating the
|
|
switch(es).
|
|
- **switches** (**Required**, list): A list of switches to initialize. The length here
|
|
must equal the number of items in the ``return`` statement of the ``lambda``.
|
|
|
|
- All options from :ref:`Switch <config-switch>`.
|
|
|
