Exemplary methods and systems relate to creating and loading a device-group snapshot, which allows the states of devices to be stored and restored by different devices. A hub system may create a device-group snapshot for a plurality of devices in a source device group and load the device-group snapshot to a target device group by: (a) receiving an instruction to load a device-group snapshot; (b) determining the target device group with devices that are available to load the device-group snapshot; (c) determining that there is a difference between device groups; (d) modifying the device-group snapshot based on the difference between device groups; and (e) communicating with devices in the target device group to load the corresponding device states from the modified device-group snapshot.
