:description: Instructions for setting up base covers in ESPHome.
:image: folder-open.svg
The ``cover`` component is a generic representation of covers in ESPHome.
A cover can (currently) either be *closed* or *open* and supports three types of
commands: *open*, *close* and *stop*.

.. _config-cover:
Base Cover Configuration
------------------------
All cover config schemas inherit from this schema - you can set these keys for covers.
.. code-block:: yaml
cover:
- platform: ...
device_class: garage
Configuration variables:
- **name** (**Required**, string): The name for the cover.
.. note::
If you have a :ref:`friendly_name <esphome-configuration_variables>` set for your device and
you want the cover to use that name, you can set ``name: None``.
- **device_class** (*Optional*, string): The device class for the
sensor. See https://www.home-assistant.io/integrations/cover/#device-class for a list of available options.
- **icon** (*Optional*, icon): Manually set the icon to use for the cover in the frontend.
Advanced options:
- **internal** (*Optional*, boolean): Mark this component as internal. Internal components will
not be exposed to the frontend (like Home Assistant). Only specifying an ``id`` without
a ``name`` will implicitly set this to true.
- **disabled_by_default** (*Optional*, boolean): If true, then this entity should not be added to any client's frontend,
(usually Home Assistant) without the user manually enabling it (via the Home Assistant UI).
Defaults to ``false``.
- **entity_category** (*Optional*, string): The category of the entity.
See https://developers.home-assistant.io/docs/core/entity/#generic-properties
for a list of available options.
Set to ``""`` to remove the default entity category.
MQTT options:
- **position_state_topic** (*Optional*, string): The topic to publish
cover position changes to.
- **position_command_topic** (*Optional*, string): The topic to receive
cover position commands on.
- **tilt_state_topic** (*Optional*, string): The topic to publish cover
cover tilt state changes to.
- **tilt_command_topic** (*Optional*, string): The topic to receive
cover tilt commands on.
- All other options from :ref:`MQTT Component <config-mqtt-component>`.
.. _cover-open_action:
``cover.open`` Action
---------------------
This :ref:`action <config-action>` opens the cover with the given ID when executed.
.. code-block:: yaml
on_...:
then:
- cover.open: cover_1
.. note::
This action can also be expressed in :ref:`lambdas <config-lambda>`:
.. code-block:: cpp
auto call = id(cover_1).make_call();
call.set_command_open();
call.perform();
.. _cover-close_action:
``cover.close`` Action
----------------------
This :ref:`action <config-action>` closes the cover with the given ID when executed.
.. code-block:: yaml
on_...:
then:
- cover.close: cover_1
.. note::
This action can also be expressed in :ref:`lambdas <config-lambda>`:
.. code-block:: cpp
auto call = id(cover_1).make_call();
call.set_command_close();
call.perform();
.. _cover-stop_action:
``cover.stop`` Action
---------------------
This :ref:`action <config-action>` stops the cover with the given ID when executed.
.. code-block:: yaml
on_...:
then:
- cover.stop: cover_1
.. note::
This action can also be expressed in :ref:`lambdas <config-lambda>`:
.. code-block:: cpp
auto call = id(cover_1).make_call();
call.set_command_stop();
call.perform();
.. _cover-toggle_action:
``cover.toggle`` Action
-----------------------
This :ref:`action <config-action>` toggles the cover with the given ID when executed,
cycling through the states close/stop/open/stop... This allows the cover to be controlled
by a single push button.
.. code-block:: yaml
on_...:
then:
- cover.toggle: cover_1
.. note::
This action can also be expressed in :ref:`lambdas <config-lambda>`:
.. code-block:: cpp
auto call = id(cover_1).make_call();
call.set_command_toggle();
call.perform();
.. _cover-control_action:
``cover.control`` Action
------------------------
This :ref:`action <config-action>` is a more generic version of the other cover actions and
allows all cover attributes to be set.
.. code-block:: yaml
on_...:
then:
- cover.control:
id: cover_1
position: 50%
tilt: 50%
Configuration variables:
- **id** (**Required**, :ref:`config-id`): The cover to control.
- **stop** (*Optional*, boolean): Whether to stop the cover.
- **state** (*Optional*, string): The state to set the cover to - one of ``OPEN`` or ``CLOSE``.
- **position** (*Optional*, float): The cover position to set.
- ``0.0`` = ``0%`` = ``CLOSED``
- ``1.0`` = ``100%`` = ``OPEN``
- **tilt** (*Optional*, float): The tilt position to set. In range 0% - 100%.
.. note::
This action can also be expressed in :ref:`lambdas <config-lambda>`:
.. code-block:: cpp
auto call = id(cover_1).make_call();
// set attributes
call.set_position(0.5);
call.perform();
.. _cover-lambda_calls:
Lambdas
-------
From :ref:`lambdas <config-lambda>`, you can access the current state of the cover (note that these
fields are read-only, if you want to act on the cover, use the ``make_call()`` method as shown above).
- ``position``: Retrieve the current position of the cover, as a value between ``0.0`` (closed) and ``1.0`` (open).
.. code-block:: cpp
if (id(my_cover).position == COVER_OPEN) {
// Cover is open
} else if (id(my_cover).position == COVER_CLOSED) {
// Cover is closed
} else {
// Cover is in-between open and closed
}
- ``tilt``: Retrieve the current tilt position of the cover, as a value between ``0.0`` and ``1.0``.
- ``current_operation``: The operation the cover is currently performing:
.. code-block:: cpp
if (id(my_cover).current_operation == CoverOperation::COVER_OPERATION_IDLE) {
// Cover is idle
} else if (id(my_cover).current_operation == CoverOperation::COVER_OPERATION_OPENING) {
// Cover is currently opening
} else if (id(my_cover).current_operation == CoverOperation::COVER_OPERATION_CLOSING) {
// Cover is currently closing
}
.. _cover-on_open_trigger:
``cover.on_open`` Trigger
*************************
This trigger is activated each time the cover reaches a fully open state.
.. code-block:: yaml
cover:
- platform: template # or any other platform
# ...
on_open:
- logger.log: "Cover is Open!"
.. _cover-on_closed_trigger:
``cover.on_closed`` Trigger
***************************
This trigger is activated each time the cover reaches a fully closed state.
.. code-block:: yaml
cover:
- platform: template # or any other platform
# ...
on_closed:
- logger.log: "Cover is Closed!"
