Abstract

The invention relates to a device (10) and method for recording a consumption variable supplied to a point of consumption. The device comprises a metering module (12) for recording the consumption variable, a first communication module (16) which is designed to communicate, preferably wirelessly, with a remote central collection unit (32) via a first communication network (30) and to transmit at least consumption-related data to the central collection unit (32); a data processing module (14) which is designed to transmit and receive radio signals via the first communication module (16) and to receive and analyze a signal generated by the metering module (12); a power supply module (24) which is designed to supply the metering module (12), the first communication module (16) and the data processing module (14) with current; and a battery (26) which is arranged such that it supplies the power supply module (24) with power. To simplify operation, it is provided that the device (10) has a second communication module (18) which is coupled to the data processing module (14) and is designed to create a wireless communication connection (34) between the data processing module (14) and a user identification means (36) of a user and to receive user data of said user, wherein the device (10) has an authentication module (22) coupled to the data processing module (14) and designed to verify the user data and assign it to an account of the user, and wherein the data processing module (14) is designed to assign the consumption variable provided to the user and recorded by the metering module (12) to the account of the user and to transmit it to the central collection unit (32) via the first communication module (16).
