Abstract: A fluid meter includes communication means arranged to receive an external opening or closing command to open or close an electromechanical valve suitable for being included in a cut-off unit mounted in the proximity of the fluid meter, authentication means arranged to authenticate a control frame including the opening or closing command, and a first communication interface arranged to transmit both the control frame and electrical energy to a second communication interface of the cut-off unit via a wireless link. The electrical energy is suitable for electrically powering the second communication interface of the cut-off unit.

Abstract: A method for transmitting meter data by a meter to a mobile device, the method including the following steps performed by the meter: receiving a request demanding meter data; obtaining meter data; generating a hashcode from at least one data pair including a serial number of the meter and the meter data obtained; encrypting the hashcode with a private key known solely to the meter, the encrypted hashcode being a signature; and transmitting to the mobile device, a frame including the meter data obtained and the signature.

Abstract: A method for transmitting consumption data by a meter to a meter data management system is described. The meter obtains (S301) consumption data, the data being obtained by metrology software. It generates (S302) a hashcode from a triplet comprising a serial number of the meter, a cyclic redundancy code calculated from the metrology software and a certificate number certifying that the meter is authorised to be used for invoicing consumption. It next encrypts (S304) the hashcode with a private key known solely to the meter, in order to obtain a signature. Finally, it transmits (S306), to the system managing said consumption data, a frame comprising an identifier of the meter, the consumption data obtained and the signature.

Abstract: A method for transmitting data from a management entity in a communication system further comprising at least one data concentrator device to which smart electricity meters are attached via a first powerline communication network, each data concentrator device being connected to the management entity via a second communication network. Said smart electricity meter receives, coming from the management entity, via the first powerline communication network, a message indicating that a transfer of data is pending with the management entity. Said smart electricity meter comprising a wireless communication interface adapted to communicate via a third wireless local communication network with a residential gateway connected to the management entity via a fourth communication network, said smart electricity meter obtains said data from the management entity via the third wireless local communication network.

Abstract: An equipment connected to a system of the AMM type that includes at least one data concentrator to which smart electricity meters, referred to as meters, are attached, via a first powerline network, each data concentrator being connected to a management system via a second network and serving as relays between said meters and the management system. The equipment is connected to a data concentrator via a third network and comprises at least one communication interface with a fourth network, said fourth network enabling at least one device connected to said fourth network to communicate with the equipment. The equipment can thus relay commands intended for a device of the actuator type connected to the fourth network and transfer alarms to the management system according to data supplied to said equipment by devices of the sensor type connected to said fourth network.

Abstract: The invention relates to equipment connected to a system of the AMM type, comprising at least one data concentrator (110) to which smart electricity meters 120, referred to as meters, are attached, via a first powerline network (101), each data concentrator being connected to a management system via a second network (102) and serving as relays between said meters and the management system. The equipment is connected to a data concentrator via a third network (104) and comprises at least one communication interface (115A, 115B) with a fourth network (105A, 105B), said fourth network enabling at least one device connected to said fourth network to communicate with the equipment. The equipment can thus relay commands intended for a device of the actuator type connected to the fourth network and transfer alarms to the management system according to data supplied to said equipment by devices of the sensor type connected to said fourth network.
