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:

```yaml
# Example configuration.yaml entry
switch:
    platform: template
    switches:
        skylight:
            friendly_name: 'Skylight'
            value_template: {% raw %}'{{ states.sensor.skylight.state }}'{% endraw %}
            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](/topics/templating/) to set the state of the switch.
  - **turn_on** (*Required*): Defines an [action](/getting-started/automation/) to run when the switch is turned on.
  - **turn_off** (*Required*): Defines an [action](/getting-started/automation/) to run when the switch is turned off.

## {% linkable_title Examples %}

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

### {% linkable_title Copy switch %}

This example shows a switch that copies another switch.

```yaml
switch:
    platform: template
    switches:
        copy:
            value_template: {% raw %}'{{ states.switch.source.state }}'{% endraw %}
            turn_on:
                service: switch.turn_on
                entity_id: switch.source
            turn_off:
                service: switch.turn_off
                entity_id: switch.source
````

### {% linkable_title Toggle switch %}

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

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

### {% linkable_title 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.

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