A control system including a control device, which is connected to a power storage device capable of supplying power to one or more electric apparatuses, and a server, by which reduction in a communication load and appropriate charge/discharge control are both achieved, is provided. When acquiring weather information from a server, a control device, on the basis of the weather information, charge to the power storage device and power supply from the power storage device to the electric apparatus. The control device decides a period from timing at which the weather information is acquired to timing at which weather information is next acquired. At second timing at which the period has elapsed from first timing at which the weather information has been acquired, the control device repeats an operation from acquisition of weather information to decision of a period after which weather information is next acquired from the server.

Control system, control device, server, and control method

A server apparatus includes a terminal-side receiver for receiving, via a first network, information including appliance information that identifies an electric appliance, from a terminal apparatus operable by a user, an appliance-side receiver for receiving, via a second network, information including an identifier of the electric appliance and information about a state of the electric appliance, and a storage unit that stores the appliance information received by the terminal-side receiver and the identifier of the electric appliance, for which it is judged, from the information about the state of the electric appliance received by the appliance-side receiver, that the appliance state has been changed, in association with each other, upon reception of trigger information by the terminal-side receiver.

Server apparatus, control system, and control method

A HEMS controller receives a control instruction of an electric appliance from a mobile terminal via a server and transmits the control instruction to the electric appliance. When no instruction is given from the mobile terminal, the HEMS controller judges whether communication with the server is continued. When judging that communication is not continued, the HEMS controller transmits, to the electric appliance, a control signal for turning off power of the electric appliance.

Controller, control system, and method for controlling control system

A control device is a control device that manages a network including a plurality of communication devices. The control device includes: a mode transition unit that makes transition to a leave mode for disconnecting a communication device from the network; an initialization-reset transmitting unit that transmits, when a notification is accepted from at least one communication device of the plurality of communication devices during the leave mode, an instruction for setting a flag and a reset order to the communication device from which the notification is accepted, the flag defining to bring the communication device back to an initial state; and a deleting unit that determines whether or not the instruction for setting the flag and the reset order are received and that deletes information about the communication device connected to the network when it is determined that the instruction for setting the flag and the reset order are received.

Control device and communication device

A network system is provided that includes at least one terminal and a server. The server sends at least one terminal information for inhibiting sending of data from at least one terminal. At least one terminal each sends the server at least a part of obtained data according to the information from the server.

Network system, communication method, server, and terminal

Provided is a communication apparatus by which a user can simply set a transmission quality in a network and QoS control effectively functions. QoS type receiving sections () are arranged in communication apparatuses () on a network, and a user is permitted to specify a QoS type to be requested to the communication apparatuses (), by operating the QoS type receiving sections (). When the communication apparatuses () perform communication, the network is controlled to ensure the QoS corresponding to the QoS type received by the QoS type receiving sections ().
