The approach we recommend is to use the power_to_kwh input process to generate a cumulative kWh feed, you can then use this to work out daily/weekly/monthly kwh etc. You can access the kWh for a particular period using the graph interface, in the statistics section it shows the difference between the start and end value of the period selected.
I’ve managed to figure out how to visualize this in home assistant, using sensors:, templates:, integration: and utility_meter:, but it gets complicated to provide simple visuals. So I was just looking for a simplified way of presenting the information.
If not possible, I will continue the way I am doing it now.
Thanks again for the input.
Attached, an image if the information in home assistant.
