Abstract: The invention relates to a computer-implemented method comprising: obtaining a series of successive time pulses from a water consumption meter placed on a water supply pipe serving at least one home, each pulse representing the consumption of a predefined volume of water at a transmission time; the detection of a use associated with a first pulse having a transmission time greater than or equal to the sum of the transmission time of the immediately preceding pulse in the series and a predefined threshold; the successive association with the use of the immediately subsequent pulses in the series, as long as the difference between the transmission time of the last pulse associated with the use and the transmission time of the immediately subsequent pulse is less than said predefined threshold; the computation of a volume of water consumed during use, said volume of water consumed during use being equal to the number of pulses associated with the use multiplied by said predefined volume; the classification of the use into a type of use, according to said volume of water consumed during use.

Abstract: Disclosed is a method for detecting domestic hot water use by a sanitary fitting during an observation period by analysing data relative to volumes of water passing through a water meter, the method including: receiving a first item of data, noted VΔ1, representing the maximum volume of fluid measured over a predetermined period, preferably equal to 5 minutes; receiving a second item of data, noted VΔ2, representing the maximum volume of fluid measured by the meter during another predetermined period, preferably equal to 15 minutes; and detecting that domestic hot water has been used when VΔ1>15 litres and VΔ2≥20 litres.
