Template cover
The template
platform can create covers that combine integrations and provides
the ability to run scripts or invoke actions 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
The configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] 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:
action: script.open_garage_door
close_cover:
action: script.close_garage_door
stop_cover:
action: 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 output values from the template are open
, opening
, closing
and closed
which are directly mapped to the corresponding states. In addition, true
is valid as a synonym to open
and false
as a synonym to closed
. If both a value_template
and a position_template
are specified, only opening
and closing
are set from the value_template
. If the template produces a None
value the state will be set to unknown
.
Defines a template to get the position of the cover. Legal values are numbers between 0
(closed) and 100
(open). If the template produces a None
value the current position will be set to unknown
.
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 entity. If the template either fails to render or returns True
, "1"
, "true"
, "yes"
, "on"
, "enable"
, or a non-zero number, the entity will be available
. If the template returns any other value, the entity will be unavailable
. If not configured, the entity will always be available
. Note that the string comparison is not case sensitive; "TrUe"
and "yEs"
are allowed.
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
). The variable position
will contain the entity’s set position.
Defines an action to set the tilt of a cover (between 0
and 100
). The variable tilt
will contain the entity’s set tilt position.
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). If the template produces a None
value the current tilt state will be set to unknown
.
Template and action variables
State-based template entities have the special template variable this
available in their templates and actions. The this
variable aids self-referencing of an entity’s state and attribute in templates and actions.
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.
Combining value_template and position_template
If both a value_template
and a position_template
are specified only opening
and closing
states are set directly from the value_template
, the open
and closed
states will instead be derived from the cover position.
value_template output | result |
---|---|
open | state defined by position_template
|
closed | state defined by position_template
|
true | state defined by position_template
|
false | state defined by position_template
|
opening | state set to opening
|
closing | state set to closing
|
No change of state or position |
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"
- action: switch.turn_on
target:
entity_id: switch.garage_door
close_cover:
- condition: state
entity_id: sensor.garage_door
state: "on"
- action: switch.turn_off
target:
entity_id: switch.garage_door
stop_cover:
action: 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 %}
