And is still doing so.

I wanted to analyse this data to get an average picture of the daily consumption, by hour:

A typical weekday looks like this:

The only thing I'd do to update this is to plonk the overall average consumption for the time period shown as a data box on the graph, e.g. "Average = 0.871 kW" for the main graph.
