:description: Instructions for setting up time-based covers in ESPHome.

|
|
The ``time_based`` cover platform allows you to create covers with position control that do not
|
|
have any position feedback. The state of the cover is thus always an assumed one, the current
|
|
position is approximated with the time the cover has been moving in a direction.

# Example configuration entry
|
|
cover:
|
|
- platform: time_based
|
|
name: "Time-Based Cover"
|
|
|
|
open_action:
|
|
- switch.turn_on: open_cover_switch
|
|
open_duration: 2.1min
|
|
|
|
close_action:
|
|
- switch.turn_on: close_cover_switch
|
|
close_duration: 2min
|
|
|
|
stop_action:
|
|
- switch.turn_off: open_cover_switch
|
|
- switch.turn_off: close_cover_switch
|
|
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **name** (**Required**, string): The name of the cover.
|
|
- **open_action** (**Required**, :ref:`Action <config-action>`): The action that should
|
|
be performed when the remote requests the cover to be opened.
|
|
- **open_duration** (**Required**, :ref:`config-time`): The amount of time it takes the cover
|
|
to open up from the fully-closed state.
|
|
- **close_action** (*Optional*, :ref:`Action <config-action>`): The action that should
|
|
be performed when the remote requests the cover to be closed.
|
|
- **close_duration** (**Required**, :ref:`config-time`): The amount of time it takes the cover
|
|
to close from the fully-open state.
|
|
- **stop_action** (**Required**, :ref:`Action <config-action>`): The action that should
|
|
be performed to stop the cover when the remote requests the cover to be stopped or
|
|
when the cover has been opening/closing for the given durations.
|
|
- **has_built_in_endstop** (*Optional*, boolean): Indicates that the cover has built in end stop
|
|
detectors. In this configuration the ``stop_action`` is not performed when the open or close
|
|
time is completed and if the cover is commanded to open or close the corresponding actions
|
|
will be performed without checking current state. Defaults to ``false``.
|
|
- **manual_control** (*Optional*, boolean): For covers with manual external controls. With this
|
|
configuration if the cover is commanded to open or close the corresponding actions will be
|
|
performed even if the current state fully open or fully closed matches desired state, then
|
|
``stop_action`` will be called after the full duration of the action elapses.
|
|
The current state will then be relearned upon completion.
|
|
It's recommended to set ``assumed_state`` to true so the cover control button aren't disabled
|
|
in the interface. 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 or disabling one of them. Defaults to ``true``.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
- All other options from :ref:`Cover <config-cover>`.
|
|
|
|
|
|
.. note::
|
|
|
|
The stop button on the UI is always enabled even when the cover is stopped and each press
|
|
on the button will cause the ``stop_action`` to be performed.
|
|
|
|
.. note::
|
|
|
|
The state of the cover can be restored from flash after a node reboot, with
|
|
``esp8266_restore_from_flash: true`` option set.
|
|
See :doc:`esp8266_restore_from_flash </components/esphome>` for details.
|
|
|
|
Handle stop_action:
|
|
------------------------
|
|
For some cover controllers, separate switches for UP and DOWN action are used while a stop is issued when sending a counter command.
|
|
This can be handled at the **stop_action** by using the following lambda function:
|
|
|
|
.. code-block:: yaml
|
|
|
|
stop_action:
|
|
- lambda: !lambda |-
|
|
if (id(cover).get_last_operation() == CoverOperation::COVER_OPERATION_OPENING) {
|
|
// Cover is currently opening
|
|
id(cover_button_down).press();
|
|
} else if (id(cover).get_last_operation() == CoverOperation::COVER_OPERATION_CLOSING) {
|
|
// Cover is currently closing
|
|
id(cover_button_up).press();
|
|
}
|
|
|
|
Be aware that ``get_last_operation`` will only return the last opening or closing operation, but not the last idle operation.
