|
|
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*.

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.
|
|
|
|
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``.
|
|
- **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.
|
|
|
|
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>`.

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`` (open) and ``1.0`` (closed).
|
|
|
|
.. 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
|
