Time Based Cover

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. The state of the cover can be restored at node reboot.

# 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:

  • open_action (Required, Action): The action that should be performed when the remote requests the cover to be opened.

  • open_duration (Required, Time): The amount of time it takes the cover to open up from the fully-closed state.

  • close_action (Optional, Action): The action that should be performed when the remote requests the cover to be closed.

  • close_duration (Required, Time): The amount of time it takes the cover to close from the fully-open state.

  • stop_action (Required, 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.

  • All other options from 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.

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:

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. This issue is tracked here.
