Use of energy utility integration (kWs -> kWh)

I have some power plugs with energy monitoring. using the Riemann sum integration I obtain energy consumption (energy rather than power). Using hour as unit time for the integral gave me inaccurate results. I changed to second.

Now results are good, however my utility meter device runs in kWs and therefore it is not available for the energy dashboard “individual devices”.

The only way making this work is creating yet another sensor (in kWh), by dividing the energy sensor (kWs) by 3600 using templates?

Is this right? Can this be done in lesser steps/sensors?
