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
Configuration Variables
List of your covers.
An ID that uniquely identifies this cover. Set this to a unique value to allow customization through the UI.
Defines a template to get the state of the cover. Valid values are open
/true
or opening
/closing
/closed
/false
. value_template
and position_template
cannot be specified concurrently.
Defines a template to get the state of the cover. Legal values are numbers between 0
(closed) and 100
(open). value_template
and position_template
cannot be specified concurrently.
Defines a template to specify which icon to use.
Defines a template for the entity picture of the cover.
Defines a template to get the available
state of the component. If the template returns true
, the device is available
. If the template returns any other value, the device will be unavailable
. If availability_template
is not configured, the component will always be available
.
Sets the class of the device, changing the device state and icon that is displayed on the frontend.
Defines an action to open the cover. If open_cover
is specified, close_cover
must also be specified. At least one of open_cover
and set_cover_position
must be specified.
Defines an action to close the cover.
Defines an action to stop the cover.
Defines an action to set to a cover position (between 0
and 100
).
Defines an action to set the tilt of a cover (between 0
and 100
).
Force cover position to use optimistic mode.
Force cover tilt position to use optimistic mode.
Defines a template to get the tilt state of the cover. Legal values are numbers between 0
(closed) and 100
(open).
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.
cover:
- platform: template
covers:
garage_door:
device_class: garage
friendly_name: "Garage Door"
position_template: "{{ states('sensor.garage_door') }}"
open_cover:
service: switch.turn_on
data:
entity_id: switch.garage_door
close_cover:
service: switch.turn_off
data:
entity_id: switch.garage_door
stop_cover:
service: switch.turn_on
data:
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:

friendly_name: "Cover Group"
open_cover:
service: script.cover_group
data:
modus: 'open'

service: script.cover_group
data:
modus: 'close'

set_cover_position:
service: script.cover_group_position
data:

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 %}
sensor:
- platform: template
sensors:
cover_group:
value_template: >-
{% if is_state('cover.bedroom', 'open') %}
open
{% elif is_state('cover.livingroom', 'open') %}
open
{% else %}
closed
{% endif %}
script:
cover_group:

- service: "cover.{{modus}}_cover"
data:
entity_id:
- cover.bedroom
- cover.livingroom
cover_group_position:
sequence:
- service: cover.set_cover_position
data:
entity_id:
- cover.bedroom
- cover.livingroom
position: "{{position}}"
automation:
- alias: "Close covers at night"
trigger:
- platform: sun
event: sunset
offset: '+00:30:00'
action:
- service: cover.set_cover_position
