In some implementations, a resident device can automatically generate scene suggestions and/or trigger suggestions based on historical data aggregated from multiple user devices. For example, a resident device can be a user device that is (e.g., mostly) kept in the home environment. Therefore, the resident device is able to collect accessory state and/or context data when another user device may not be connected to the accessories in the home environment. Moreover, the resident device can collect and/or aggregate accessory state data, context data, and user device state data from across multiple user devices. The resident device can automatically determine the accessories and/or corresponding accessory states for a scene and/or scene triggers based on historical patterns of use represented in the aggregated historical accessory state data. The user device can present suggest scenes and/or triggers to the user of the user device.
