Utility Meter shows extremely high and incorrect values

Hello everyone,

I have an entity in Home Assistant that can only increase (it is a kWh integral sensor based on a sensor whose values can never fall below 0).

Example:
Tonight, the sensor has increased by approx. 0.3 kWh since 2 a.m. (the consumption meter has only existed since 2 a.m.). I would also have expected this value from the consumption meter.


The curve clearly shows that the sensor never drops.
According to the consumption meter (which is supposed to reset itself daily), the value tonight was over 250 kWh.

However, the consumption meter (which is supposed to reset itself daily) shows a value of over 250 kWh for the same time. The curve of the consumption meter roughly matches that of the integral sensor:

Nevertheless, it makes no sense to me why the consumption meter reports such extremely high and incorrect values.

When activating the consumption counter, I activated the differential values option as this seemed logical - after all, the integral sensor is constantly increasing and I only want to record the difference between the values:


Does anyone have any idea why the consumption meter is displaying such high and incorrect values?

The “delta values” option (as it is called in English) is for devices which report only the change since the previous reading. Your integral sensor doesn’t do that.

Your integral sensor reports, for example: 1.4, 1.5, 1.8, 1.85, etc.

A delta values sensor, for the same readings, would report 0.1, 0.1, 0.3, 0.05, etc.
