:description: Instructions for setting up generic outputs in ESPHome
:image: folder-open.png
Each platform of the ``output`` domain exposes some output to
ESPHome. These are grouped into two categories: ``binary`` outputs
(that can only be ON/OFF) and ``float`` outputs (like PWM, can output
any rational value between 0 and 1).
.. _config-output:
Base Output Configuration
-------------------------
Each output platform extends this configuration schema.
.. code-block:: yaml
# Example configuration entry
output:
- platform: ...
id: my_output_id
power_supply: power_supply_id
inverted: False
max_power: 0.75
Configuration variables:
- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
- **power_supply** (*Optional*, :ref:`config-id`): The :doc:`power
supply </components/power_supply>` to connect to
this output. When the output is enabled, the power supply will
automatically be switched on too.
- **inverted** (*Optional*, boolean): If the output should be treated
as inverted. Defaults to ``False``.
- **max_power** (*Optional*, float): Only for float outputs. Sets the
maximum output value of this output platform. Each value will be
multiplied by this. Must be in range from 0 to 1. Defaults to 1.
.. _output-turn_on_action:
``output.turn_on`` Action
*************************
This action turns the output with the given ID on when executed.
.. code-block:: yaml
on_...:
then:
- output.turn_on: relay_1
.. note::
This action can also be expressed in :ref:`lambdas <config-lambda>`:
.. code-block:: cpp
id(relay_1).turn_on();
.. _output-turn_off_action:
``output.turn_off`` Action
**************************
This action turns the output with the given ID off when executed.
.. code-block:: yaml
on_...:
then:
- output.turn_off: relay_1
.. note::
This action can also be expressed in :ref:`lambdas <config-lambda>`:
.. code-block:: cpp
id(relay_1).turn_off();
.. _output-set_level_action:
``output.set_level`` Action
***************************
This action sets the float output to the given level when executed. Note: This only
works with floating point outputs like ESP8266 PWM or LEDC.
.. code-block:: yaml
on_...:
then:
- output.set_level:
id: output_1
level: 50%
.. note::
This action can also be expressed in :ref:`lambdas <config-lambda>`:
.. code-block:: cpp
// range is 0.0 (off) to 1.0 (on)
id(relay_1).set_level(0.5);
