Sonoff S31 to calculate power consumption by hour instead of by day

Recently I bought a Sonoff S31 to calculate power consumption.
I used the suggested APP called “ewelink”, it has the data export function, but only calculated by day… I need it to be calculated by hour, is there any easy way to achieve my goal?

Thanks.

Create a utility meter from your ewelink kwh sensor:

And set the cycle to hourly.
