Abstract

An equipment can function according to a plurality of operating modes that include a deep standby mode in which the energy consumption is minimum, an active mode in which the energy consumption is maximum and a light standby mode in which the energy consumption is intermediate between deep standby and active mode, a change from the deep standby mode to the active mode being slower than a change from the light standby mode to the active mode. The method enables an electricity meter supervising an electricity network to which an item of equipment is connected to control the change of said equipment to light standby mode. To do this, the meter implements a procedure for the detection of human presence based on an analysis of the electrical consumption in the electricity network and activates the light standby mode of the equipment when a user is detected.

Dependent claims

A system comprising an item of equipment and an electricity meter, the equipment being able to function in a plurality of operating modes comprising a deep standby mode in which power consumption of said equipment is minimum, an active mode in which the power consumption of the equipment is maximum and a light standby mode in which the power consumption of the equipment is intermediate between the deep standby mode and the active mode, some of the internal devices of the equipment being deactivated and/or the power supply to these internal devices being cut off when the equipment goes into light standby mode, a change from deep standby mode to active mode being slower than a change from light standby mode to active mode, the equipment being supplied by an electrical network of a building supervised by the electricity meter, the equipment and the electricity meter being able to communicate by means of a communication network, wherein the electricity meter comprised in the system comprises electronic components configured for:

detecting a human presence in the building by analysing the electrical consumption in the electrical network;
sending a message to the equipment by means of the communication network requesting a change of the equipment to light standby mode when a human presence is detected;
receiving said message by means of the communication network, and
making the equipment go into light standby mode.

using a procedure for detecting a human presence in the building based on an analysis of the electrical consumption in the electrical network;
and,
when a human presence is detected, sending a message to the equipment, by means of the communication network, requesting that the equipment go into light standby mode.

receiving a message by means of the communication network requesting change of the equipment to light standby mode, the message having been sent by the electricity meter following detection of a human presence in the building by a procedure for detecting a human presence based on an analysis of the electrical consumption in the electrical network, and
causing the equipment to go into light standby mode.
