Template

The template integration allows creating entities which derive their values from other data. This is done by specifying templates for properties of an entity, like the name or the state.

There is currently support for the following device types within Home Assistant:

Alarm control panel
Binary sensor
Button
Cover
Fan
Image
Light
Lock
Number
Select
Sensor
Switch
Vacuum
Weather

Configuration

To add the Template helper to your Home Assistant instance, use this My button:

Manual configuration steps

If the above My button doesn’t work, you can also perform the following steps manually:

Browse to your Home Assistant instance.
Go to Settings > Devices & Services.
At the top of the screen, select the tab: Helpers.
In the bottom right corner, select the Create helper button.
From the list, select Template.
Follow the instructions on screen to complete the setup.

Important

To be able to add Helpers via the user interface, you should have default_config: in your configuration.yamlThe 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]. It should already be there by default unless you removed it.

Note

Configuration using our user interface provides a more limited subset of options, making this integration more accessible while covering most use cases.

If you need more specific features for your use case, the manual YAML-configuration section of this integration might provide them.

YAML configuration

Entities are defined in your YAML configuration files under the template: key. You can define multiple configuration blocks as a list. Each block defines sensor/binary sensor/number/select entities and can contain optional update triggers.

State-based template entities

Template entities will by default update as soon as any of the referenced data in the template updates.

For example, you can have a template that takes the averages of two sensors. Home Assistant will update your template sensor as soon as either source sensor updates.

template:
  - sensor:
      - name: "Average temperature"
        unit_of_measurement: "°C"
        state: >
          {% set bedroom = states('sensor.bedroom_temperature') | float %}
          {% set kitchen = states('sensor.kitchen_temperature') | float %}

          {{ ((bedroom + kitchen) / 2) | round(1, default=0) }}YAML

Trigger-based template entities

If you want more control over when an entity updates, you can define triggers. Triggers follow the same format and work exactly the same as triggers in automations. This feature is a great way to create entities based on webhook data (example), or update entities based on a schedule.

Whenever a trigger fires, all related entities will re-render and it will have access to the trigger data in the templates.

Trigger-based entities do not automatically update when states referenced in the templates change. This functionality can be added back by defining a state trigger for each entity that you want to trigger updates.

The state, including attributes, of trigger-based sensors and binary sensors is restored when Home Assistant is restarted. The state of other trigger-based template entities is not restored.

Note

Buttons do not support using trigger or action options.

# Example configuration entry
template:
  - triggers:
      - trigger: time_pattern
        # This will update every night
        hours: 0
        minutes: 0
    sensor:
      # Keep track how many days have past since a date
      - name: "Not smoking"
        state: '{{ ( ( as_timestamp(now()) - as_timestamp(strptime("06.07.2018", "%d.%m.%Y")) ) / 86400 ) | round(default=0) }}'
        unit_of_measurement: "Days"YAML

actions list (Optional)

Define actions to be executed when the trigger fires (for trigger-based entities only). Optional. Variables set by the action script are available when evaluating entity templates. This can be used to interact with anything using actions, in particular actions with response data. See action documentation.

conditions list (Optional)

Define conditions that have to be met after a trigger fires and before any actions are executed or sensor updates are performed (for trigger-based entities only). Optional. See condition documentation.

triggers list (Optional)

Define one or multiple automation triggers to update the entities. Optional. If omitted will update based on referenced entities. See trigger documentation.

unique_id string (Optional)

The unique ID for this config block. This will be prefixed to all unique IDs of all entities in this block.

variables map (Optional)

Key-value pairs of variable definitions which can be referenced and used in the templates below (for trigger-based entities only). Mostly used by blueprints. With State-based template entities, variables are only resolved when the configuration is loaded or reloaded. Trigger based template entities resolve variables between triggers and actions.

variable_name: value string Required

The variable name and corresponding value.

Common Device Configuration Options

Each entity platform has its own set of configuration options, but there are some common options that can be used across all entity platforms.

# Example configuration.yaml entry
template:
  - binary_sensor:
      # Common configuration options
    - unique_id: my_unique_sensor_id
      variables:
        my_entity: sensor.watts
      availability: "{{ my_entity | has_value }}"
      icon: "{{ 'mdi:flash-alert' if states(my_entity) | float > 100 else 'mdi:flash' }}"
      name: "{{ states(my_entity) }} Alert"
      # Entity specific configuration options

# Example state-based configuration.yaml entry
template:
  - alarm_control_panel:
      - name: "Alarm Control Panel 1"
        state: "{{ states('input_select.panel_1_state') }}"
        arm_away:

Binary Sensor

The template binary sensor platform allows you to create binary sensors with templates to define the state and attributes.

Binary sensor entities can be created from the frontend in the Helpers section or via YAML.

# Example state-based configuration.yaml entry
template:
  - binary_sensor:
      - name: Sun Up
        state: >
          {{ is_state("sun.sun", "above_horizon") }}YAML

# Example trigger-based configuration.yaml entry
template:
  - triggers:
    - trigger: state
      entity_id: sun.sun
    binary_sensor:
      - name: Sun Up
        state: >
          {{ is_state("sun.sun", "above_horizon") }}YAML

Configuration Variables

binary_sensor list Required

List of binary sensors

attributes map (Optional)

Defines templates for attributes of the entity.

attribute: template template Required

The attribute and corresponding template.

auto_off time (Optional)

Requires a trigger. After how much time the entity should turn off after it rendered ‘on’.

delay_off time (Optional)

The amount of time the template state must be not met before this sensor will switch to off. This can also be a template.

delay_on time (Optional)

The amount of time (e.g. 0:00:05) the template state must be met before this sensor will switch to on. This can also be a template.

device_class device_class (Optional, default: None)

Sets the class of the device, changing the device state and icon that is displayed on the UI (see below). It does not set the unit_of_measurement.

state template Required

The sensor is on if the template evaluates as True, yes, on, enable or a positive number. Any other value will render it as off. The actual appearance in the frontend (Open/Closed, Detected/Clear etc) depends on the sensor’s device_class value

State based binary sensor - Washing Machine Running

This example creates a washing machine “load running” sensor by monitoring an energy meter connected to the washer. During the washer’s operation, the energy meter will fluctuate wildly, hitting zero frequently even before the load is finished. By utilizing delay_off, we can have this sensor only turn off if there has been no washer activity for 5 minutes.

# Example configuration.yaml entry
# Determine when the washing machine has a load running.
template:
  - binary_sensor:
      - name: "Washing Machine"
        delay_off:
          minutes: 5
        state: >
          {{ states('sensor.washing_machine_power')|float > 0 }}YAML

State based binary sensor - Is Anyone Home

This example is determining if anyone is home based on the combination of device tracking and motion sensors. It’s extremely useful if you have kids/baby sitter/grand parents who might still be in your house that aren’t represented by a trackable device in Home Assistant. This is providing a composite of Wi-Fi based device tracking and Z-Wave multisensor presence sensors.

# Example configuration.yaml entry
template:
  - binary_sensor:
      - name: People home
        state: >
          {{ is_state('device_tracker.sean', 'home')
             or is_state('device_tracker.susan', 'home')
             or is_state('binary_sensor.office_124', 'on')
             or is_state('binary_sensor.hallway_134', 'on')
             or is_state('binary_sensor.living_room_139', 'on')
             or is_state('binary_sensor.porch_ms6_1_129', 'on')
             or is_state('binary_sensor.family_room_144', 'on') }}YAML

State based binary sensor - device tracker sensor with latitude and longitude attributes

This example shows how to combine a non-GPS (e.g., NMAP) and GPS device tracker while still including latitude and longitude attributes

# Example configuration.yaml entry
template:
  - binary_sensor:
      - name: My Device
        state: >
          {{ is_state('device_tracker.my_device_nmap', 'home') or is_state('device_tracker.my_device_gps', 'home') }}
        device_class: "presence"
        attributes:
          latitude: >
            {% if is_state('device_tracker.my_device_nmap', 'home') %}
              {{ state_attr('zone.home', 'latitude') }}
            {% else %}
              {{ state_attr('device_tracker.my_device_gps', 'latitude') }}
            {% endif %}
          longitude: >
            {% if is_state('device_tracker.my_device_nmap', 'home') %}
              {{ state_attr('zone.home', 'longitude') }}
            {% else %}
              {{ state_attr('device_tracker.my_device_gps', 'longitude') }}
            {% endif %}YAML

State based binary sensor - Change the icon when a state changes

This example demonstrates how to use template to change the icon as its state changes. This icon is referencing its own state.

# Example configuration.yaml entry
template:
  - binary_sensor:
      - name: Sun Up
        state: >
          {{ is_state("sun.sun", "above_horizon") }}
        icon: >
          {% if is_state("binary_sensor.sun_up", "on") %}
            mdi:weather-sunset-up
          {% else %}
            mdi:weather-sunset-down
          {% endif %}YAML

Trigger based binary sensor - Change state and icon when a custom event is received

A more advanced use case could be to set the icon based on the sensor’s own state like above, but when triggered by an event. This example demonstrates a binary sensor that turns on momentarily, such as when a doorbell button is pressed.

The binary sensor turns on and sets the matching icon when the appropriate event is received. After 5 seconds, the binary sensor turns off automatically. To ensure the icon gets updated, there must be a trigger for when the state changes to off.

# Example configuration.yaml entry
template:
  - triggers:
      - trigger: event
        event_type: YOUR_EVENT
      - trigger: state
        entity_id: binary_sensor.doorbell_rang
        to: "off"
    binary_sensor:
      name: doorbell_rang
      icon: "{{ (trigger.platform == 'event') | iif('mdi:bell-ring-outline', 'mdi:bell-outline') }}"
      state: "{{ trigger.platform == 'event' }}"
      auto_off:
        seconds: 5YAML

Button

The template button platform allows you to create button entities with scripts to define each action.

Button entities can be created from the frontend in the Helpers section or via YAML.

# Example configuration.yaml entry
template:
  - button:
      - name: Fast Forward
        press:
          action: remote.send_command
          target:
            entity_id: remote.living_room
          data:
            command: fast_forwardYAML

Cover

The template cover platform allows you to create covers with templates to define the state and scripts to define each action.

Cover entities can only be created from YAML.

# Example state-based configuration.yaml entry
template:
  - cover:
      - name: Garage Door
        state: "{{ states('sensor.garage_door')|float > 0 }}"
        device_class: garage
        open_cover:
          action: script.open_garage_door
        close_cover:
          action: script.close_garage_door
        stop_cover:
          action: script.stop_garage_doorYAML

# Example trigger-based configuration.yaml entry
template:
  - triggers:
      - trigger: state
        entity_id: sensor.garage_door
    cover:
      - name: Garage Door
        state: "{{ trigger.to_state.state|float(0) > 0 }}"
        device_class: garage
        open_cover:
          action: script.open_garage_door
        close_cover:
          action: script.close_garage_door
        stop_cover:
          action: script.stop_garage_doorYAML

Configuration Variables

cover map

Characteristics of a cover

close_cover action (Inclusive)

Defines an action to close the cover.

device_class string (Optional)

Sets the class of the device, changing the device state and icon that is displayed on the frontend.

open_cover action (Inclusive)

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.

optimistic boolean (Optional, default: false)

Force cover position to use optimistic mode.

position template (Optional)

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.

set_cover_position action (Optional)

Defines an action to set to a cover position (between 0 and 100). The variable position will contain the entity’s set position.

set_cover_tilt_position action (Optional)

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.

state template (Optional)

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 state and a position template are specified, only opening and closing are set from the state template. If the template produces a None value the state will be set to unknown.

stop_cover action (Optional)

Defines an action to stop the cover.

tilt template (Optional)

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.

tilt_optimistic boolean (Optional, default: false)

Force cover tilt position to use optimistic mode.

Cover Optimistic Mode

In optimistic mode, the cover position state is maintained internally. This mode is automatically enabled if neither state or position 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 is not specified or when the tilt_optimistic attribute is used.

Combining state and position templates

If both a state and a position are specified only opening and closing states are set directly from the state, 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

State based 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.

template:
  - cover:
      - name: Garage Door
        device_class: garage
        position: "{{ 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

Defines an action to run when the fan is given a preset command.

set_oscillating action (Optional)

Defines an action to run when the fan is given an oscillation state command.

set_direction action (Optional)

Defines an action to run when the fan is given a direction command.

speed_count integer (Optional, default: 100)

The number of speeds the fan supports. Used to calculate the percentage step for the fan.increase_speed and fan.decrease_speed actions.

state template Required

Defines a template to get the state of the fan. Valid values: on, off.

turn_on action Required

Defines an action to run when the fan is turned on.

turn_off action Required

Defines an action to run when the fan is turned off.

Converting from speeds to percentage

When converting a fan with 3 speeds from the old fan entity model, the following percentages can be used:

0 - off 33 - low 66 - medium 100 - high

State based fan - Helper fan

This example uses an input_boolean and an input_number to mimic a fan, and the example shows multiple actions for set_percentage.

template:
  - fan:
      - name: "Helper Fan"
        state: "{{ states('input_boolean.state') }}"
        turn_on:
          - action: input_boolean.turn_on
            target:
              entity_id: input_boolean.state
        turn_off:
          - action: input_boolean.turn_off
            target:
              entity_id: input_boolean.state
        speed_count: 6
        percentage: >
          {{ states('input_number.percentage') if is_state('input_boolean.state', 'on') else 0 }}
        set_percentage:
          - action: input_boolean.turn_{{ 'on' if percentage > 0 else 'off' }}
            target:
              entity_id: input_boolean.state
          - action: input_number.set_value
            target:
              entity_id: input_number.percentage
            data:
              value: "{{ percentage }}"YAML

State based fan - Fan with preset modes

This example uses an existing fan with only a percentage. It extends the percentage value into useable preset modes without a helper entity.

template:
  - fan:
      - name: "Preset Mode Fan Example"
        state: "{{ states('fan.percentage_fan') }}"
        turn_on:
          - action: fan.turn_on
            target:
              entity_id: fan.percentage_fan
        turn_off:
          - action: fan.turn_off
            target:
              entity_id: fan.percentage_fan
        percentage: >
          {{ state_attr('fan.percentage_fan', 'percentage') }}
        speed_count: 3
        set_percentage:
          - action: fan.set_percentage
            target:
              entity_id: fan.percentage_fan
            data:
              percentage: "{{ percentage }}"
        preset_modes:
          - "off"
          - "low"
          - "medium"
          - "high"
        preset_mode: >
          {% if is_state('fan.percentage_fan', 'on') %}
            {% if state_attr('fan.percentage_fan', 'percentage') == 100  %}
              high
            {% elif state_attr('fan.percentage_fan', 'percentage') == 66 %}
              medium
            {% else %}
              low
            {% endif %}
          {% else %}
            off
          {% endif %}
        set_preset_mode:
          - action: fan.set_percentage
            target:
              entity_id: fan.percentage_fan
            data:
              percentage: >-
                {% if preset_mode == 'high' %}
                  100
                {% elif preset_mode == 'medium' %}
                  66
                {% elif preset_mode == 'low' %}
                  33

Image

The template image platform allows you to create image entities with templates to define the image URL.

Image entities can be created from the frontend in the Helpers section or via YAML.

# Example state-based configuration.yaml entry
template:
  - image:
      - name: "My Image"
        url: "http://example.com/image.jpg"YAML

# Example trigger-based configuration.yaml entry
template:
  - triggers:

light map Required

List of your lights.

effect template (Inclusive, default: optimistic)

Defines a template to get the effect of the light.

effect_list template (Inclusive, default: optimistic)

Defines a template to get the list of supported effects. Must render a list.

hs template (Optional, default: optimistic)

Defines a template to get the HS color of the light. Must render a tuple (hue, saturation).

level template (Optional, default: optimistic)

Defines a template to get the brightness of the light.

min_mireds template (Optional, default: optimistic)

Defines a template to get the minimum mired value of the light.

max_mireds template (Optional, default: optimistic)

Defines a template to get the maximum mired value of the light.

rgb template (Optional, default: optimistic)

Defines a template to get the RGB color of the light. Must render a tuple or a list (red, green, blue).

rgbw template (Optional, default: optimistic)

Defines a template to get the RGBW color of the light. Must render a tuple or a list (red, green, blue, white).

rgbww template (Optional, default: optimistic)

Defines a template to get the RGBWW color of the light. Must render a tuple or a list (red, green, blue, cold white, warm white).

set_effect action (Inclusive)

Defines an action to run when the light is given an effect command. Receives the variable effect. May also receive the variables brightness, and/or transition.

set_level action (Optional)

Defines an action to run when the light is given a brightness command. The script will only be called if the turn_on call only ha brightness, and optionally transition. Receives variables brightness and, optionally, transition.

set_temperature action (Optional)

Defines an action to run when the light is given a color temperature command. Receives variable color_temp. May also receive variables brightness and/or transition.

set_hs action (Optional)

Defines an action to run when the light is given a hs color command. Available variables: hs as a tuple, h and s

set_rgb action (Optional)

Defines an action to run when the light is given an RGB color command. Available variables: rgb as a tuple, r, g and b.

set_rgbw action (Optional)

Defines an action to run when the light is given an RGBW color command. Available variables: rgbw as a tuple, rgb as a tuple, r, g, b and w.

set_rgbww action (Optional)

Defines an action to run when the light is given an RGBWW color command. Available variables: rgbww as a tuple, rgb as a tuple, r, g b, cw and ww.

state template (Optional, default: optimistic)

Defines a template to set the state of the light. If not defined, the switch will optimistically assume all commands are successful.

supports_transition template (Optional, default: false)

Defines a template to get if the light supports transition. Should return a boolean value (True/False). If this value is True, the transition parameter in a turn on or turn off call will be passed as a named parameter transition in either of the scripts.

temperature template (Optional, default: optimistic)

Defines a template to get the color temperature of the light.

turn_on action Required

Defines an action to run when the light is turned on. May receive the variables brightness and/or transition.

turn_off action Required

Defines an action to run when the light is turned off. May receive the variable transition.

Light Considerations

Transition doesn’t have its own script, it will instead be passed as a named parameter transition to the turn_on, turn_off, brightness, color_temp, effect, hs_color, rgb_color, rgbw_color or rgbww_color scripts. Brightness will be passed as a named parameter brightness to either of turn_on, color_temp, effect, hs_color, rgb_color, rgbw_color or rgbww_color scripts if the corresponding parameter is also in the call. In this case, the brightness script (set_level) will not be called. If only brightness is passed to light.turn_on action, then set_level script is called.

State based light - Theater Volume Control

This example shows a light that is actually a home theater’s volume. This integration gives you the flexibility to provide whatever you’d like to send as the payload to the consumer including any scale conversions you may need to make; the media player integration needs a floating point percentage value from 0.0 to 1.0.

# Example configuration.yaml entry
template:

Lock

The template lock platform allows you to create locks with templates to define the state and scripts to define each action.

Lock entities can only be created from YAML.

# Example state-based configuration.yaml entry
template:
  - lock:
      - name: Garage door
        state: "{{ is_state('sensor.door', 'on') }}"
        lock:
          action: switch.turn_on
          target:
            entity_id: switch.door
        unlock:
          action: switch.turn_off
          target:
            entity_id: switch.doorYAML

# Example trigger-based configuration.yaml entry
template:
  - triggers:

lock map Required

List of locks

code_format template (Optional, default: None)

Defines a template to get the code_format attribute of the entity. This template must evaluate to a valid Python regular expression or None. If it evaluates to a not-None value, you are prompted to enter a code when interacting with the lock. The code will be matched against the regular expression, and the lock/unlock actions will be executed only if they match. The actual validity of the entered code must be verified within these actions. If there’s a syntax error in the template, the entity will be unavailable. If the template fails to render for other reasons or if the regular expression is invalid, no code will be accepted, and the lock/unlock actions will never be invoked.

lock action Required

Defines an action to run when the lock is locked.

open action (Optional)

Defines an action to run when the lock is opened.

optimistic boolean (Optional, default: false)

Flag that defines if the lock works in optimistic mode.

state template Required

Defines a template to set the state of the lock.

unlock action Required

Defines an action to run when the lock is unlocked.

State based lock - Lock from a switch

This example shows a lock that copies data from a switch.

template:
  - lock:
      - name: Garage Door
        state: "{{ is_state('switch.source', 'on') }}"
        lock:
          action: switch.turn_on
          target:
            entity_id: switch.source
        unlock:
          action: switch.turn_off
          target:
            entity_id: switch.sourceYAML

State based lock - Optimistic mode

This example shows a lock in optimistic mode. This lock will immediately change state after command and will not wait for state update from the sensor.

template:
  - lock:
      - name: Garage Door
        state: "{{ is_state('sensor.skylight.state', 'on') }}"
        optimistic: true
        lock:
          action: switch.turn_on
          target:
            entity_id: switch.source
        unlock:
          action: switch.turn_off
          target:
            entity_id: switch.sourceYAML

State based lock - Sensor and Two Switches

This example shows a lock that takes its state from a sensor, and uses two momentary switches to control a device.

template:
  - lock:
      - name: Garage Door
        state: "{{ is_state('sensor.skylight.state', 'on') }}"
        lock:
          action: switch.turn_on
          target:
            entity_id: switch.skylight_open
        unlock:
          action: switch.turn_on
          target:
            entity_id: switch.skylight_closeYAML

State based lock - Secret code

This example shows a lock that copies data from a switch. It needs a PIN code defined as a secret to unlock and no code to lock. Note that the actual validity check of the code is part of the unlock action and should always happen there or in scripts called from these actions. In this way, you can not only perform code checks against static values, but also dynamic ones (for instance, TOTPs).

template:
  - lock:
      - name: Garage Door
        state: "{{ is_state('switch.source', 'on') }}"
        code_format: "{{ '\\d{4}' if is_state('switch.source', 'on') else None }}"
        lock:
          - action: switch.turn_on
            target:
              entity_id: switch.source
        unlock:
          - variables:
              pin: !secret garage_door_pin
          - condition: "{{ code == pin }}"
          - action: switch.turn_off
            target:
              entity_id: switch.sourceYAML

In secrets.yaml:

garage_door_pin: "1234"YAML

Number

The template number platform allows you to create number entities with templates to define the state and scripts to define each action.

      unique_id: porch_camera_day_night_mode
      state: "{{ state_attr('camera.porch_camera_sd', 'day_night_mode') }}"
      options: "{{ ['off', 'on', 'auto'] }}"
      select_option:

          target:
            entity_id: camera.porch_camera_sdYAML

Sensor

The template sensor platform allows you to create sensors with templates to define the state and attributes.

Sensor entities can be created from the frontend in the Helpers section or via YAML.

# Example state-based configuration.yaml entry
template:
  - sensor:
      - name: "Kettle"
        state: >
          {% if is_state('switch.kettle', 'off') %}
            off
          {% elif state_attr('switch.kettle', 'W')|float < 1000 %}
            standby
          {% elif is_state('switch.kettle', 'on') %}
            on
          {% else %}
            failed
          {% endif %}YAML

# Example trigger-based configuration.yaml entry

        - unavailable
    sensor:
      - name: Outside Temperature
        device_class: temperature
        unit_of_measurement: °C
        state: "{{ (states('sensor.outside_temperature') | float - 32) * 5/9 }}"YAML

Configuration Variables

Looking for your configuration file?

sensor list Required

List of sensors

attributes map (Optional)

Defines templates for attributes of the entity.

attribute: template template Required

The attribute and corresponding template.

last_reset template (Optional, default: None)

Defines a template that describes when the state of the sensor was last reset. Must render to a valid datetime. Only available when state_class is set to total

state template Required

Defines a template to get the state of the sensor. If the sensor is numeric, i.e. it has a state_class or a unit_of_measurement, the state template must render to a number or to none. The state template must not render to a string, including unknown or unavailable. An availability template may be defined to suppress rendering of the state template.

state_class string (Optional, default: None)

The state_class of the sensor. This will also display the value based on the user profile Number Format setting and influence the graphical presentation in the history visualization as a continuous value. If you desire to include the sensor in long-term statistics, include this key and assign it the appropriate value

unit_of_measurement string (Optional, default: None)

Defines the units of measurement of the sensor, if any. This will also display the value based on the user profile Number Format setting and influence the graphical presentation in the history visualization as a continuous value.

State based sensor - Exposing sun angle

This example shows the sun angle in the frontend.

template:
  - sensor:
      - name: Sun Angle
        unit_of_measurement: "°"
        state: "{{ '%+.1f'|format(state_attr('sun.sun', 'elevation')) }}"YAML

State based sensor - Modifying another sensor’s output

If you don’t like the wording of a sensor output, then the Template Sensor can help too. Let’s rename the output of the Sun integration as a simple example:

template:
  - sensor:
      - name: "Sun State"
        state: >
          {% if is_state('sun.sun', 'above_horizon') %}
            up
          {% else %}
            down
          {% endif %}YAML

State based sensor - Changing the unit of measurement of another sensor

With a Template Sensor, it’s easy to convert given values into others if the unit of measurement doesn’t fit your needs. Because the sensors do math on the source sensor’s state and need to render to a numeric value, an availability template is used to suppress rendering of the state template if the source sensor does not have a valid numeric state.

template:
  - sensor:
      - name: "Transmission Down Speed"
        unit_of_measurement: "kB/s"
        state: "{{ states('sensor.transmission_down_speed')|float * 1024 }}"
        availability: "{{ is_number(states('sensor.transmission_down_speed')) }}"

      - name: "Transmission Up Speed"
        unit_of_measurement: "kB/s"
        state: "{{ states('sensor.transmission_up_speed')|float * 1024 }}"
        availability: "{{ is_number(states('sensor.transmission_up_speed')) }}"YAML

Trigger based sensor - Using conditions to control updates

This example shows how to store the last valid value of a temperature sensor. It will update as long as the source sensor has a valid (numeric) state. Otherwise, the template sensor’s state will remain unchanged.

template:
  - triggers:
      trigger: state
      entity_id: sensor.outside_temperature
    conditions:
      - condition: template
        value_template: "{{ is_number(states('sensor.outside_temperature')) }}"
    sensor:
      - name: Outside Temperature last known value
        state: "{{ states('sensor.outside_temperature') }}"YAML

Switch

The template switch platform allows you to create switches with templates to define the state and scripts to define each action.

Switch entities can be created from the frontend in the Helpers section or via YAML.

# Example state-based configuration.yaml entry
template:
  - switch:
      - name: Skylight
        state: "{{ is_state('binary_sensor.skylight', 'on') }}"
        turn_on:
          action: switch.turn_on
          target:
            entity_id: switch.skylight_open
        turn_off:
          action: switch.turn_off
          target:
            entity_id: switch.skylight_closeYAML

# Example trigger-based configuration.yaml entry
template:
  - triggers:
      - trigger: state
        entity_id: binary_sensor.skylight
    switch:
      - name: Skylight
        state: "{{ is_state('binary_sensor.skylight', 'on') }}"
        turn_on:
          action: switch.turn_on
          target:
            entity_id: switch.skylight_open
        turn_off:
          action: switch.turn_off
          target:

        turn_on:
          action: switch.toggle
          target:
            entity_id: switch.blind_toggle
        turn_off:
          action: switch.toggle
          target:
            entity_id: switch.blind_toggleYAML

State based switch - Sensor and Two Switches

This example shows a switch that takes its state from a sensor, and uses two momentary switches to control a device.

template:
  - switch:
      - name: "Skylight"
        value_template: "{{ is_state('sensor.skylight', 'on') }}"
        turn_on:

template:
  - switch:
      - name: "Blind"
        turn_on:
          action: switch.toggle
          target:

        state: "{{ now().isoformat() }}"
        attributes:
          forecast: "{{ hourly['weather.home'].forecast }}"YAML

Video tutorial

This video tutorial explains how to set up a trigger based template that makes use of an action to retrieve the weather forecast (precipitation).

Combining multiple template entities

The template integration allows defining multiple sections.

# Example configuration.yaml entry with two sections
template:
  # Define state-based template entities
  - sensor:
      ...
  - binary_sensor:
      ...

  # Define trigger-based template entities
  - triggers:
      ...
    sensor:
      ...
    binary_sensor:
      ...YAML

Trigger based sensor and binary sensor storing webhook information

Template entities can be triggered using any automation trigger, including webhook triggers. Use a trigger-based template entity to store this information in template entities.

template:
  - triggers:
      - trigger: webhook
        webhook_id: my-super-secret-webhook-id
    sensor:
      - name: "Webhook Temperature"
        state: "{{ trigger.json.temperature }}"
        unit_of_measurement: °C

      - name: "Webhook Humidity"
        state: "{{ trigger.json.humidity }}"
        unit_of_measurement: %

    binary_sensor:
      - name: "Motion"
        state: "{{ trigger.json.motion }}"
        device_class: motionYAML

You can test this trigger entity with the following CURL command:

Template and action variables

State-based and trigger-based template entities have the special template variable this available in their templates and actions. The this variable is the current state object of the entity and aids self-referencing of an entity’s state and attributes in templates and actions. Trigger-based entities also provide the trigger data.

Note

Self-referencing using this provides the state and attributes for the entity before rendering the templates to calculate a new state. In other words, it contains the previous state.

Self referencing

This example demonstrates how the this variable can be used in templates for self-referencing.

template:
  - sensor:
      - name: test
        state: "{{ this.attributes.test | default('Value when missing') }}"
        # not: "{{ state_attr('sensor.test', 'test') }}"
        attributes:
          test: "{{ now() }}"YAML

Optimistic mode

For template entities that support interactivity (like number and select), you can enable optimistic mode by setting the optimistic parameter to true. This affects how the entity’s state updates when you interact with it:

With optimistic mode disabled (default): When you interact with the entity (for example, selecting a new option in a dropdown or setting a new number value), the entity’s state in Home Assistant will only update after the underlying template defined in the state parameter returns the new value.
With optimistic mode enabled: When you interact with the entity, the entity’s state in Home Assistant immediately updates to reflect your change, without waiting for the state template to update. This provides a more responsive UI experience but may not reflect the actual state if the underlying action fails or takes time to complete.

Optimistic mode is particularly useful when:

The underlying system doesn’t provide immediate feedback
You want a more responsive UI experience
You’re confident the action will succeed

When optimistic mode is disabled (default), you get more accuracy but potentially a less responsive UI, as the entity only updates after confirmation from the underlying system.

Rate limiting updates

When there are entities present in the template and no triggers are defined, the template will be re-rendered when one of the entities changes states. To avoid this taking up too many resources in Home Assistant, rate limiting will be automatically applied if too many states are observed.

Tip

Define a trigger to avoid a rate limit and get more control over entity updates.

When states is used in a template by itself to iterate all states on the system, the template is re-rendered each time any state changed event happens if any part of the state is accessed. When merely counting states, the template is only re-rendered when a state is added or removed from the system. On busy systems with many entities or hundreds of thousands state changed events per day, templates may re-render more than desirable.

In the below example, re-renders are limited to once per minute because we iterate over all available entities:

template:
  - binary_sensor:
      - name: "Has Unavailable States"
        state: "{{ states | selectattr('state', 'in', ['unavailable', 'unknown', 'none']) | list | count }}"YAML

In the below example, re-renders are limited to once per second because we iterate over all entities in a single domain (sensor):

template:
  - binary_sensor:
      - name: "Has Unavailable States"
        state: "{{ states.sensor | selectattr('state', 'in', ['unavailable', 'unknown', 'none']) | list | count }}"YAML

If the template accesses every state on the system, a rate limit of one update per minute is applied. If the template accesses all states under a specific domain, a rate limit of one update per second is applied. If the template only accesses specific states, receives update events for specifically referenced entities, or the homeassistant.update_entity action is used, no rate limit is applied.

Considerations

Startup

If you are using the state of a platform that might not be available during startup, the Template Sensor may get an unknown state. To avoid this, use the states() function in your template. For example, you should replace {{ states.sensor.moon.state }} with this equivalent that returns the state and never results in unknown: {{ states('sensor.moon') }} .

The same would apply to the is_state() function. You should replace {{ states.switch.source.state == 'on' }} with this equivalent that returns true/false and never gives an unknown result:

{{ is_state('switch.source', 'on') }}YAML

Using blueprints

If you’re just starting out and are not really familiar with templates, we recommend that you start with blueprintA blueprint is a script, automation, or template entity configuration with certain parts marked as configurable. This allows users to create multiple scripts, automations or template entities based on the same blueprint, with each having its own configuration-specific settings. Blueprints are shared by the community on the blueprints exchange in the forum. [Learn more] template entities. These are template entities which are ready-made by the community and that you only need to configure.

Each blueprint contains the “recipe” for creating a single template entity, but you can create multiple template entities based on the same blueprint.

To create your first template entity based on a blueprint, open up your configuration.yaml file and add:

# Example configuration.yaml template entity based on a blueprint located in config/blueprints/homeassistant/inverted_binary_sensor.yaml
template:
  - use_blueprint:
      path: homeassistant/inverted_binary_sensor.yaml # relative to config/blueprints/template/
      input:
        reference_entity: binary_sensor.foo
    name: Inverted foo
    unique_id: inverted_fooYAML

If you look at the blueprint definition, you will notice it has one input defined (reference_entity), which expects a binary_sensor entity ID. When you create a template entity based on that blueprint, you will have to tell it which of your binary_sensor entities it should use to fill that spot.

Importing blueprints

Home Assistant can import blueprints from the Home Assistant forums, GitHub, and GitHub gists.

To import a blueprint, first find a blueprint you want to import.
- If you just want to practice importing, you can use this URL:
  https://github.com/home-assistant/core/blob/dev/homeassistant/components/template/blueprints/inverted_binary_sensor.yaml
  Text
Download the file and place it under config/blueprints/template/<source or author>/<blueprint name>.yaml
Use a config similar to the one above to create a new template entity based on the blueprint you just imported.
Make sure to fill in all required inputs.

The blueprint can now be used for creating template entities.

Event event_template_reloaded

Event event_template_reloaded is fired when Template entities have been reloaded and entities thus might have changed.

This event has no additional data.

Defines a template to get the available state of the integration. 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 integration will always be available.

device_class device_class (Optional, default: None)

Sets the class of the device, changing the device state and icon that is displayed on the UI (see below). It does not set the unit_of_measurement.

Legacy Switch configuration format

This format still works but is no longer recommended. Use modern configuration.

This format is configured as a platform for the switch integration and not directly under the template integration.

# Example configuration.yaml entry
switch:
  - platform: template
    switches:
      skylight:
        value_template: "{{ is_state('sensor.skylight', 'on') }}"
        turn_on:
          action: switch.turn_on
          target:
            entity_id: switch.skylight_open
        turn_off:
          action: switch.turn_off
          target:
            entity_id: switch.skylight_closeYAML
