The ``cover`` component is a generic representation of covers in ESPHome.
2018-06-01 18:10:00 +02:00
A cover can (currently) either be *closed* or *open* and supports three types of
commands: *open*, *close* and *stop*.

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:
- **device_class** (*Optional*, string): The device class for the
sensor. See https://www.home-assistant.io/components/cover/ for a list of available options.
- **icon** (*Optional*, icon): Manually set the icon to use for the cover in the frontend.
2019-05-12 22:44:59 +02:00
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).
Requires Home Assistant 2021.9 or newer. Defaults to ``false``.
2021-11-07 19:24:55 +01:00
- **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. Requires Home Assistant 2021.11 or newer.
Set to ``""`` to remove the default entity category.
2021-10-10 17:54:39 +02:00
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-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.

- ``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

Lambdas
-------

2021-09-16 02:46:32 +02:00
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).
2018-06-07 15:55:31 +02:00
2022-09-22 06:26:36 +02:00
- ``position``: Retrieve the current position of the cover, as a value between ``0.0`` (closed) and ``1.0`` (open).
2018-06-07 15:55:31 +02:00
2021-09-16 02:46:32 +02:00
.. 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
}
2021-10-10 17:54:39 +02:00
2021-09-16 02:46:32 +02:00
- ``tilt``: Retrieve the current tilt position of the cover, as a value between ``0.0`` and ``1.0``.
2018-06-07 15:55:31 +02:00
2021-09-16 02:46:32 +02:00
- ``current_operation``: The operation the cover is currently performing:

2021-09-16 02:46:32 +02:00
.. 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
}

- logger.log: "Cover is Open!"
.. _cover-on_closed_trigger:
``cover.on_closed`` Trigger
***************************
