Plot hourly distribution of kWh

Hi,
Since I pay for electricity by hourly rate, it would be of interest to plot the accumulated energy usage as a function of hour, if you understand what I mean.

For example, all the kWhs used between 04-05 in the morning for the last week or month.
Had anyone found a way to do this, without external software like Excel?

Hello @Daniel_B and welcome to the forum!

The process described here will work for what you need Calculating Daily kWh - Guide | OpenEnergyMonitor just adjust the interval to hourly in the graph view rather than daily.
