History issue

I have got sensor that measure daily power usage.

When I click Pokaż więcej (show more) i got more detailed view, and it is where magic happens:


here is zoomed:

As you can see there is a spike to almost 7000kWh at 20:28:30.
Why its visible this plot, and not visible at first one?
From where this spike comes from?

The first plot (more info pop-up) is using long term statistics 5 minute averages. This is to reduce loading times but is lower resolution.

The show more (history) plot is of the actual state data.

From whichever integration you used to create the sensor.

So I have:
1.integral that counts total power usage → Pomocnik Prąd Total
2.I have Utility meter → Dzienne zużycie prądu total that resets every day and
Periodically resetting and Sensor always available is ON

For what reason that spikes occurs? on this utility meter?

What does the source sensor history for this look like?

So it looks like there was no communication with sensor till this spike:

Is anything that I can do to not show that spikes in utility meter in future?

For your integral sensor, use method: left not trapezoidal.
