Abstract
An ancillary apparatus arranged to be mounted on an electricity meter which includes a primary port to which the electricity meter applies a supply voltage includes a secondary port arranged to be connected to the primary port when the apparatus is mounted on the meter, the apparatus thus being electrically powered by the supply voltage, and a secondary processing unit arranged to transmit a message to the meter by modulating a supply current of the apparatus that is produced by the meter and flows via the primary port and the secondary port.
