Template Output
===============

:description: Instructions for setting up template outputs with ESPHome.
:image: description.svg
The ``template`` output component can be used to create templated binary and float outputs in ESPHome.
.. code-block:: yaml
# Example configuration entry
output:
- platform: template
id: outputsplit
type: float
write_action:
- output.set_level:
id: output1
level: !lambda return state;
- output.set_level:
id: output2
level: !lambda return state;
- platform: ...
id: output1
- platform: ...
id: output2
Configuration variables:
------------------------
- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
- **type** (**Required**, string): The type of output. One of ``binary`` and ``float``.
- **write_action** (**Required**, :ref:`Automation <automation>`): An automation to perform
when the state of the output is updated.
- All other options from :ref:`Output <config-output>`.
See :apiclass:`output::BinaryOutput` and :apiclass:`output::FloatOutput`.
.. warning::
This is an **output component** and will not be visible from the frontend. Output components are intermediary
components that can be attached to for example lights.
.. _output-template-on_write_action:
``write_action`` Trigger
------------------------
When the state for this output is updated, the ``write_action`` is triggered.
It is possible to access the state value inside Lambdas:
.. code-block:: yaml
- platform: template
id: my_output
type: float
write_action:
- if:
condition:
lambda: return ((state > 0) && (state < .4));
then:
- output.turn_on: button_off
- delay: 500ms
- output.turn_off: button_off
