The aggregation function determines the weighted average depending on the time interval (every 10 minutes). If the time interval changes within a period, e.g. from 10 minutes to 12 minutes, then the values with the time interval 10 minutes are first added and divided by the number of read values. The values are then added together with the time interval 12 minutes and divided by the number of values read. The weighted average is formed from the two results of the two time intervals (result1 + result2)/2=x.
