METHOD FOR OPERATING A CONSUMPTION METER SYSTEM AND CONSUMPTION METER

摘要

A method operates a consumption meter system, in which the consumption of a supply medium by a consumer is determined using a consumption meter. A consumption value is transmitted in the form of data between the consumption meter and a first receiver. The first receiver is assigned to a higher-level supplier and the data are transmitted between the consumption meter and the first receiver via a first data channel. The data are encrypted on the meter side using a first key for transmission via the first data channel. A second data channel is provided for transmitting the data between the consumption meter and a second receiver. The data are encrypted on the meter side by a second key for transmission via the second data channel.
