I'm greatly impressed with the KP125M smart plugs that I've added to my collection, and, in particular, the energy reporting function.  This may be a daunting ask, but rather than exporting the consumption history of each plug individually, it would be great if we could also export the combined data of a designated group.  So, for example, if you have multiple KP125M smart plugs (and, in future, any similarly capable switches) all controlling your lighting, and all of these devices are linked to a specific group, you could export the total amount of the energy consumed by the members of that group.
