Touchscreen Components
|
|
======================

|
|
|
|
The ``touchscreen`` component holds the base code for most touchscreen components
|
|
available in ESPHome and is responsible for passing the touch events to
|
|
``binary_sensors`` with the ``touchscreen`` platform.
|
|
|
|
.. _config-touchscreen:
|
|
|
|
Base Touchscreen Configuration
|
|
------------------------------
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example touchscreen
|
|
touchscreen:
|
|
- platform: ...
|
|
on_touch:
|
|
then:
|
|
...
|
|
|
|
Configuration variables:
|
|
************************
|
|
|
|
- **on_touch** (*Optional*, :ref:`Automation <automation>`): An automation to perform
|
|
when the touchscreen is touched. See :ref:`touchscreen-on_touch`.
|
|
- **display** (**Required**, :ref:`config-id`): The display to use. If only one display is
|
|
available, this can be omitted.
|
|
|
|
.. _touchscreen-on_touch:
|
|
|
|
``on_touch`` Trigger
|
|
--------------------
|
|
|
|
This automation will be triggered when the touchscreen detects a touch.
|
|
|
|
This trigger provides one arguments of type :apistruct:`touchscreen::TouchPoint` which has two integer members: ``x`` and ``y`` which
|
|
represent the position of the touch in relation to the display width and height. It also has optional members that will be set
|
|
depending on the touchscreen platform.
|
|
|
|
Binary Sensor
|
|
-------------
|
|
|
|
The ``touchscreen`` binary sensor allows you to setup areas on the touch screen as virtual
|
|
buttons.
|
|
|
|
.. code-block:: yaml
|
|
|
|
binary_sensor:
|
|
- platform: touchscreen
|
|
name: Top Left Touch Button
|
|
x_min: 0
|
|
x_max: 100
|
|
y_min: 0
|
|
y_max: 100
|
|
page_id: home_page_id
|
|
|
|
Configuration variables:
|
|
************************
|
|
|
|
- **name** (*Optional*, string): The name for the binary sensor.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
- **touchscreen_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the touchscreen.
|
|
- **x_min** (**Required**, int): Left coordinate of the screen area to be detected as the virtual button.
|
|
- **x_max** (**Required**, int): Right coordinate of the screen area to be detected as the virtual button.
|
|
- **y_min** (**Required**, int): Top coordinate of the screen area to be detected as the virtual button.
|
|
- **y_max** (**Required**, int): Bottom coordinate of the screen area to be detected as the virtual button.
|
|
- **page_id** (*Optional*, :ref:`config-id`): Only trigger this binary sensor if the display is showing this page.
|
|
|
|
- All other options from :ref:`Binary Sensor <config-binary_sensor>`.
