Abstract

A method and a device are used during battery operation of a smart metering meter equipped with a consumption sensor and a transmit clock generator for a radio module for transmitting consumption data packets, in the event of a decreased residual capacity of the battery, to determine if the data packets can be transmitted as previously with the residual capacity over the residual time period until a scheduled battery exchange at the end of a specified operating time period. If not, the transmit power, for example, of the data packets is reduced and/or their transmit clock is extended over the residual period. This determination, along with a control specification, are preferably performed in a concentrator and are transmitted to the meter by using bidirectionally operating radio modules so that computer capacities required therefor need not be retained in each individual meter of a supply area.
