--- title: "Scenes" description: "Instructions on how to setup scenes within Home Assistant." --- You can create scenes that capture the states you want certain entities to be. For example, a scene can specify that light A should be turned on and light B should be bright red. ```yaml # Example configuration.yaml entry scene: - name: Romantic entities: light.tv_back_light: "on" light.ceiling: state: "on" xy_color: [0.33, 0.66] brightness: 200 - name: Movies entities: light.tv_back_light: state: "on" brightness: 125 light.ceiling: off media_player.sony_bravia_tv: state: "on" source: HDMI 1 state: "on" ``` ## How to configure your scene In the scene you define in your YAML files, please ensure you use all required parameters as listed below. {% configuration %} name: description: Friendly name of the scene. required: true type: string description: description: Description of the scene. required: true type: string entities: description: Entities to control and their desired state. required: true type: list {% endconfiguration %} As you can see, there are two ways to define the states of each `entity_id`: - Define the `state` directly with the entity. Be aware, that `state` needs to be defined. - Define a complex state with its attributes. You can see all attributes available for a particular entity under `developer-tools -> state`. Scenes can be activated using the service `scene.turn_on` (there is no 'scene.turn_off' service). ```yaml # Example automation automation: trigger: platform: state entity_id: device_tracker.sweetheart from: "not_home" to: "home" action: service: scene.turn_on target: entity_id: scene.romantic ``` ## Applying a scene without defining it With the `scene.apply` service you are able to apply a scene without first defining it via configuration. Instead, you pass the states as part of the service data. The format of the data is the same as the `entities` field in a configuration. ```yaml # Example automation automation: trigger: platform: state entity_id: device_tracker.sweetheart from: "not_home" to: "home" action: service: scene.apply data: entities: light.tv_back_light: state: "on" brightness: 100 light.ceiling: off media_player.sony_bravia_tv: state: "on" source: HDMI 1 ``` ## Using scene transitions Both the `scene.apply` and `scene.turn_on` services support setting a transition, which enables you to smoothen the transition to the scene. This is an example of an automation that sets a romantic scene, in which the light will transition to the scene in 2.5 seconds. ```yaml # Example automation automation: trigger: platform: state entity_id: device_tracker.sweetheart from: "not_home" to: "home" action: service: scene.turn_on target: entity_id: scene.romantic data: transition: 2.5 ``` Transitions are currently only support by lights, which in their turn, have to support it as well. However, the scene itself does not have to consist of only lights to have a transition set. ## Reloading scenes Whenever you make a change to your scene configuration, you can call the `scene.reload` service to reload the scenes.
