A system that monitors at least a household electric user (HA1–HA4), in particular a household appliance, includes a monitoring device (MSA) that is connected between a source of electric energy (OUT) and the electric user, the monitoring device (MSA) including a metering means for detecting one or more electric quantities being associated with the operation of said user (HA1–HA4), and further including a control means that is programmed for (i) comparing the electric quantity or quantities being measured through the metering means with reference values of said electric quantity or quantities which are stored within the control means; (ii) generating, in function of the comparison, information being representative of the current operating status or phase of operation of the electric user (HA1–HA4); and (iii) allowing for the reading or transmission of the information to the outside of said device (MSA). The monitoring device also including a communication means, for realizing a transmission and/or reception of data or information on the electric supply line which connects the user (HA1–HA4) to the device (MSA), by means of a modulation of electric power between the user (HA1–HA4) and the device (MSA) and/or vice-versa.
