Template Cover

The template platform can create covers that combine integrations and provides the ability to run scripts or invoke services for each of the open, close, stop, position and tilt commands of a cover.

Configuration

To enable Template Covers in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
cover:
  - platform: template
    covers:
      garage_door:
        device_class: garage
        friendly_name: "Garage Door"
        value_template: "{{ states('sensor.garage_door')|float > 0 }}"
        open_cover:
          service: script.open_garage_door
        close_cover:
          service: script.close_garage_door
        stop_cover:
          service: script.stop_garage_door

Considerations

If you are using the state of a platform that takes extra time to load, the Template Cover may get an unknown state during startup. This results in error messages in your log file until that platform has completed loading. If you use is_state() function in your template, you can avoid this situation. For example, you would replace {{ states.cover.source.state == 'open' }} with this equivalent that returns true/false and never gives an unknown result: {{ is_state('cover.source', 'open') }}

Optimistic Mode

In optimistic mode, the cover position state is maintained internally. This mode is automatically enabled if neither value_template or position_template are specified. Note that this is unlikely to be very reliable without some feedback mechanism, since there is otherwise no way to know if the cover is moving properly. The cover can be forced into optimistic mode by using the optimistic attribute. There is an equivalent mode for tilt_position that is enabled when tilt_template is not specified or when the tilt_optimistic attribute is used.

Examples

In this section you will find some real-life examples of how to use this cover.

Garage Door

This example converts a garage door with a controllable switch and position sensor into a cover. The condition check is optional, but suggested if you use the same switch to open and close the garage.

cover:
  - platform: template
    covers:
      garage_door:
        device_class: garage
        friendly_name: "Garage Door"
        position_template: "{{ states('sensor.garage_door') }}"
        open_cover:
          - condition: state
            entity_id: sensor.garage_door
            state: "off"
          - service: switch.turn_on
            target:
              entity_id: switch.garage_door
        close_cover:
          - condition: state
            entity_id: sensor.garage_door
            state: "on"
          - service: switch.turn_off
            target:
              entity_id: switch.garage_door
        stop_cover:
          service: switch.turn_on
          target:
            entity_id: switch.garage_door
        icon_template: >-
          {% if states('sensor.garage_door')|float > 0 %}
            mdi:garage-open
          {% else %}
            mdi:garage
          {% endif %}

Multiple Covers

This example allows you to control two or more covers at once.

homeassistant:
  customize:
    cover_group:
      assumed_state: true

cover:
  - platform: template
    covers:
      cover_group:
        friendly_name: "Cover Group"
        open_cover:
          service: script.cover_group
          data:
            modus: "open"
        close_cover:
          service: script.cover_group
          data:
            modus: "close"
        stop_cover:
          service: script.cover_group
          data:
            modus: "stop"
        set_cover_position:
          service: script.cover_group_position
          data:
            position: "{{position}}"
        value_template: "{{is_state('sensor.cover_group', 'open')}}"
        icon_template: >-
          {% if is_state('sensor.cover_group', 'open') %}
            mdi:window-open
          {% else %}
            mdi:window-closed
          {% endif %}

          {% elif is_state('cover.livingroom', 'open') %}
            open
          {% else %}

            - cover.bedroom
            - cover.livingroom
        data:
          position: "{{position}}"

automation:
  - alias: "Close covers at night"
    trigger:
      - platform: sun
        event: sunset
        offset: "+00:30:00"
    action:
      - service: cover.set_cover_position
        target:
