Problems solved by technology
However, some people may want to block such messages to avoid features, so these people will not be bothered by service cuts
One possible solution to combat this type of action would be to require devices to acknowledge disable requests, but this would cause scalability issues due to complex processing on the server side and a surge of upstream messages that would overload the network 20
Also, mandatory confirmations can be tampered with by sending false confirmation messages

Embodiment Construction
[0020] see figure 1 , the main components that act according to the present invention will be disclosed as follows. The figure discloses three main areas, namely the management center 10 , the network 20 and the end user area 30 . The end user zone 30 includes one or more consumables 31 . The operation of each of these appliances can be selected by an automatic selector switch 35 actuated by an energy saving device 40 . The device 40 receives control messages 11 from the management center 10 via the network 20 . The network 20 may be any type of network, such as ADSL, PLC (Power Line Carrier Communication), 3G / 4G network or the like.
[0021] Each appliance 31 has a default mode corresponding to a low power consumption mode. Without any control message 11 from the management center 10, the appliance 31 cannot be powered in any other way than its default mode. As a result, all appliances can remain in low energy mode without any intervention from the manager hub. In order...

The present invention relates to a system and method for controlling the operating of at least one consumption appliance (31) by means of an automated selector switch (35) controlled by an energy saving device (40) connected to a management center (10) for switching said consumption appliance (31) between several operating modes, namely at least a limited power default mode and a free power mode. The method comprising the steps of: keeping the consumption appliance (31) in its default power mode, until receiving, by the energy saving device (40), an authentic secured control message (11) sent from a management center (10), said control message (11) comprising a least a command onto the mode in which the consumption appliance (31) has to be switched, then initializing a counter (44) with an initialization value, triggering the counting of said counter (44), switching the consumption appliance (31) in the mode indicated by the command comprised in the control message (11) either until the counter (44) has reached a predefined threshold value or until the energy saving device (40) receives another authentic secured control message (11) from the management center (10), if the counter (44) has reached said predefined threshold value, then switching the consumption appliance (31) in its default power mode, if another authentic secured control message (11) has been received, then returning to the step of initializing the counter (44).
Description
technical field [0001] The invention relates to the field of smart grids and aims at saving energy by controlling the energy supply of consumers such as electrical equipment of personal, commercial or industrial consumers. Although the invention will be described below in connection with electrical loads, it should be understood that other types of energy or loads, such as gas or water, that can be measured by utility meters are also contemplated in the invention. Background technique [0002] In the context of energy conservation and optimization, a facility provider or any other organization becomes concerned with the ability to control energy usage. The need to limit energy consumption can often be predicted in advance, since peak usage is usually predictable, for example by comparison with past usage and / or by forecasting temperatures for the next few days. Certain uses are considered less critical than others and may be temporarily set to a low energy consumption mode,...
