Meter readings evaluation

Evaluate meter readings for electricity, water or gas. The server calculates consumption per period and reports outliers and falling readings.

Input

Result

A table of readings with consumption, days and value per day, the totals by meter and a list of outliers and falling readings.

Meter readings say little until they are turned into consumption. This tool calculates the consumption between two readings for each meter, also per day when the dates are known. Periods far from the mean and readings lower than the one before are reported. Several meters stay separate and are never added together. Prices and causes are not assessed.

Questions and answers

Who does the calculation?

The server calculates all sums from the table. The AI only writes the text and cannot change the figures.

How is an outlier found?

A period is reported when it differs from the mean of its meter by at least the set percentage. With known dates, the value per day is compared. At least three periods are needed.

What about a falling reading or a new meter?

A lower reading is reported and no consumption is calculated for that step. The next period starts from the new reading.

Is my text stored?

Only as long as needed: 7 days on Free, 30 days with a package – or not at all if you choose not to store it. Processing happens on our own servers in the EU (Poland).
