I guess your data is electricity consumption per home per hour or something like that.
Personally, I would keep the per home aspect because one home will behave similarly from day to day and from week to week. But then again it depends on which approach you prefer…
A model that can read in several days/weeks worth of data for one home and base its predictions on that might turn out to be very effective.
Another approach that might make more sense would be to average the data per hour over all the homes.
