Template Switch

The template platform creates switches that combine components.

For example, if you have a garage door with a toggle switch that operates the motor and a sensor that allows you know whether the door is open or closed, you can combine these into a switch that knows whether the garage door is open or closed.

This can simplify the gui, and make it easier to write automations. You can mark the components you have combined as hidden so they don’t appear themselves.

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

# Example configuration.yaml entry
switch:
    platform: template
    switches:
        skylight:
            friendly_name: 'Skylight'
            value_template: '{{ states.sensor.skylight.state }}'
            turn_on:
                service: switch.turn_on
                entity_id: switch.skylight_open
            turn_off:
                service: switch.turn_on
                entity_id: switch.skylight_close

Configuration variables:

switches array (Required): List of your switches.
- friendly_name (Optional): Name to use in the Frontend.
- value_template (Required): Defines a template to set the state of the switch.
- turn_on (Required): Defines an action to run when the switch is turned on.
- turn_off (Required): Defines an action to run when the switch is turned off.

Examples

In this section you find some real life examples of how to use this switch.

Copy switch

This example shows a switch that copies another switch.

switch:
    platform: template
    switches:
        copy:
            value_template: '{{ states.switch.source.state }}'
            turn_on:
                service: switch.turn_on
                entity_id: switch.source
            turn_off:
                service: switch.turn_off
                entity_id: switch.source

Toggle switch

This example shows a switch that takes its state from a sensor, and toggles a switch.

switch:
    platform: template
    switches:
        blind:
            friendly_name: 'Blind'
            value_template: '{{ state }}'
            turn_on:
                service: switch.toggle
                entity_id: switch.blind_toggle
            turn_off:
                service: switch.toggle
                entity_id: switch.blind_toggle

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.

switch:
    platform: template
    switches:
        skylight:
            friendly_name: 'Skylight'
            value_template: '{{ states.sensor.skylight.state }}'
            turn_on:
                service: switch.turn_on
                entity_id: switch.skylight_open
            turn_off:
                service: switch.turn_on
                entity_id: switch.skylight_close
