One more vote for being able to aggregate the data from multiple Vue2s.
In my case, I needed to monitor more than 16 circuits so I purchased another Vue2, not using the main clamps on this second Vue2 and I have it nested under the primary Vue2.
While this allows me to monitor more than 16 circuits, the sorting of the circuits with largest usage is thrown off. It would be better if the app simply allows you to aggregate the data into one “virtual” Vue.
