|
The ``template`` cover platform allows you to create simple covers out of just a few
|
|
actions and a value lambda. Once defined, it will automatically appear in Home Assistant
|
|
as a cover and can be controlled through the frontend.

# Example configuration entry
|
|
cover:
|
|
- platform: template
|
|
name: "Template Cover"
|
|
lambda: |-
|
|
if (id(top_end_stop).state) {
|
|
return COVER_OPEN;
|
|
} else {
|
|
return COVER_CLOSED;
|
|
}
|
|
open_action:
|
|
- switch.turn_on: open_cover_switch
|
|
close_action:
|
|
- switch.turn_on: close_cover_switch
|
|
stop_action:
|
|
- switch.turn_on: stop_cover_switch
|
|
optimistic: true
|
|
|
|
|
|
Possible return values for the optional lambda:
|
|
|
|
- ``return COVER_OPEN;`` if the cover should be reported as OPEN.
|
|
- ``return COVER_CLOSED;`` if the cover should be reported as CLOSED.
|
|
- ``return {};`` if the last state should be repeated.
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **lambda** (*Optional*, :ref:`lambda <config-lambda>`):
|
|
Lambda to be evaluated repeatedly to get the current state of the cover.
|
|
- **open_action** (*Optional*, :ref:`Action <config-action>`): The action that should
|
|
be performed when the remote (like Home Assistant's frontend) requests the cover to be opened.
|
|
- **close_action** (*Optional*, :ref:`Action <config-action>`): The action that should
|
|
be performed when the remote requests the cover to be closed.
|
|
- **stop_action** (*Optional*, :ref:`Action <config-action>`): The action that should
|
|
be performed when the remote requests the cover to be stopped.
|
|
- **toggle_action** (*Optional*, :ref:`Action <config-action>`): The action that should
|
|
be performed when the remote requests to toggle the the cover.
|
|
- **optimistic** (*Optional*, boolean): Whether to operate in optimistic mode - when in this mode,
|
|
any command sent to the template cover will immediately update the reported state and no lambda
|
|
needs to be used. Defaults to ``false``.
|
|
- **assumed_state** (*Optional*, boolean): Whether the true state of the cover is not known.
|
|
This will make the Home Assistant frontend show buttons for both OPEN and CLOSE actions, instead
|
|
of hiding one of them. Defaults to ``false``.
|
|
- **has_position** (*Optional*, boolean): Whether this cover will publish its position as a floating point number.
|
|
By default (``false``), the cover only publishes OPEN/CLOSED position.
|
|
- **tilt_action** (*Optional*, :ref:`Action <config-action>`): The action that should
|
|
be performed when the remote (like Home Assistant's frontend) requests the cover be set to a specific
|
|
tilt position. The desired tilt is available in the lambda in the ``tilt`` variable.
|
|
- **tilt_lambda** (*Optional*, :ref:`lambda <config-lambda>`):
|
|
Lambda to be evaluated repeatedly to get the current tilt position of the cover.
|
|
- **position_action** (*Optional*, :ref:`Action <config-action>`): The action that should
|
|
be performed when the remote (like Home Assistant's frontend) requests the cover be set to a specific
|
|
position. The desired position is available in the lambda in the ``pos`` variable.
|
|
Useless if `has_position` is not set to ``true``.
|
|
- All other options from :ref:`Cover <config-cover>`.

``cover.template.publish`` Action
|
|
---------------------------------
|
|
|
|
You can also publish a state to a template cover from elsewhere in your YAML file
|
|
with the ``cover.template.publish`` action.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
cover:
|
|
- platform: template
|
|
name: "Template Cover"
|
|
id: template_cov
|
|
|
|
# in some trigger
|
|
on_...:
|
|
- cover.template.publish:
|
|
id: template_cov
|
|
state: OPEN
|
|
|
|
# Templated
|
|
- cover.template.publish:
|
|
id: template_cov
|
|
state: !lambda 'return COVER_OPEN;'
|
|
|
|
Configuration options:
|
|
|
|
- **id** (**Required**, :ref:`config-id`): The ID of the template cover.
|
|
- **state** (*Optional*, :ref:`templatable <config-templatable>`):
|
|
The state to publish. One of ``OPEN``, ``CLOSED``. If using a lambda, use ``COVER_OPEN`` or ``COVER_CLOSED``.
|
|
- **position** (*Optional*, :ref:`templatable <config-templatable>`, float):
|
|
The position to publish, from 0 (CLOSED) to 1.0 (OPEN)
|
|
- **tilt** (*Optional*, :ref:`templatable <config-templatable>`, float):
|
|
The tilt position to publish, from 0 (CLOSED) to 1.0 (OPEN)
|
|
- **current_operation** (*Optional*, :ref:`templatable <config-templatable>`, string):
|
|
The current operation mode to publish. One of ``IDLE``, ``OPENING`` and ``CLOSING``. If using a lambda, use ``COVER_OPERATION_IDLE``, ``COVER_OPERATION_OPENING``, and ``COVER_OPERATION_CLOSING``.
|
|
|
|
.. note::
|
|
|
|
This action can also be written in lambdas:
|
|
|
|
.. code-block:: cpp
|
|
|
|
id(template_cov).position = COVER_OPEN;
|
|
id(template_cov).tilt = 0.5;
|
|
id(template_cov).publish_state();
|
|
