Accuracy of Energy Statistics component?

[poldim]

Hey,
I've added your component to my Sonoff S31 and see the data is pretty different from the native component. Have you done a similar check? Wondering if it's my config, device, or one of the components? The data from your component averages being 55% of the native component.

Comparison of daily max for garage_controls_s31_energy_today vs garage_controls_s31_total_daily_energy_native_esphome_component.

date	dentra	native	delta
9/7/23	0.67	1.3	52%
9/8/23	0.4	0.705	57%
9/9/23	0.37	0.72	51%
9/10/23	0.29	0.547	53%
9/11/23	0.66	1.21	55%
9/12/23	0.46	0.875	53%
9/13/23	0.36	0.688	52%
9/14/23	0.75	1.43	52%
9/15/23	0.29	0.406	71%
9/16/23	0.37	0.648	57%
9/17/23	0.11	0.211	52%

My component has been actively tested and actually works together with the zmai-90; there are practically no deviations in readings from the main meter over several years of use.

you calculate the data differently so you see different results

I'm using a Sonoff S31.

Any pointers to what's calculated differently? do you think the delta filter is causing the large difference in calculated result?
