In some implementations, a computing device can automatically generate a scene. For example, a scene can be a collection of accessories and corresponding accessory states. When the scene is invoked, the computing device can cause the accessories associated with the scene to assume the corresponding accessory states. The computing device can automatically determine the accessories and/or corresponding accessory states for a scene based on historical patterns of use represented in historical accessory state data. The computing device can generate a scene based on a snapshot of current accessory states for the accessories associated with the scene.
