In some implementations, a user device can automatically generate scene suggestions and/or trigger suggestions. For example, a scene can be a collection of accessories and corresponding accessory states. When the scene is invoked, the user device can cause the accessories associated with the scene to assume the corresponding accessory states. The user 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 user device can automatically determine triggers for automatically invoking scenes based on historical patterns of use. For example, the user device can analyze historical context (e.g., location, time, accessory state, etc.) data associated with accessory state transitions to determine triggers for automatically invoking a scene. The user device can present suggest scenes and/or triggers to the user of the user device.
