Abstract: The present invention aims to provide a method by which a user recognizes that firmware of a control device related to a remote monitoring system is being updated. In a remote monitoring system including a mobile terminal operated by a user, a server that communicates with the mobile terminal, and the control device that communicates with the server, the mobile terminal communicates with the control device through the server, and the server knows start and completion of an update of firmware of the control device by communicating with the control device. In a case where an operating instruction to the control device is issued from the mobile terminal while the firmware of the control device is being updated, the server notifies the mobile terminal that the firmware of the control device is being updated.

Abstract: A management system for managing measurement information on power consumption in at least one electrical appliance which is associated with at least one meter includes a first storage module configured to store measurement information transmitted from each of the at least one meter associated with the at least one electrical appliance, on power consumption in the at least one electrical appliance, in correspondence with the at least one meter. The management system also includes a second storage module configured to store history information on association between each of the at least one meter and the at least one electrical appliance.

Abstract: A power management device includes an obtaining portion for obtaining information on power consumption from a plurality of electrical appliances, a display portion, and a controller for causing the display portion to display information on power consumption in the plurality of electrical appliances obtained through the obtaining portion. In each electrical appliance, a plurality of pieces of attribute information are set in advance in association, the controller carries out grouping of the plurality of electrical appliances in a plurality of layers based on the plurality of pieces of attribute information, and for each group categorized through grouping into the plurality of layers, the controller causes information on power consumption in an electrical appliance belonging to the group to be displayed.

Abstract: Provided is a controller capable of making a user aware of a consumption amount of electricity at a preferred time. A home controller (100) includes a communication interface (105) configured to receive an electrical power consumption of a plurality of devices (200A to 200E), a memory (101) configured to store changes in the electrical power consumption of the plurality of devices (200A to 200E), and a processor (110) configured to determine whether or not a change amount or a change rate in the electrical power consumption is greater than a predefined range for each of the plurality of devices (200A to 200E) and output information indicating the electrical power consumption of a device having the change amount or the change rate in the electrical power consumption greater than the predefined range.

Abstract: When power failure occurs at a power grid, a controller obtains information related to an operating state of a plurality of electrical appliances; restrict an operation of at least some of electrical appliances currently operating among the plurality of electrical appliances, such that power consumption of the plurality of electric appliances does not exceed a first upper limit during a period in which the remaining amount in a storage battery is below a first threshold value; and restrict an operation of at least some of electrical appliances currently operating among the plurality of electrical appliances, such that power consumption of the plurality of electric appliances does not exceed a second upper limit during a period in which the remaining amount in the storage battery is greater than or equal to a first threshold value and below a second threshold value that is larger than the first threshold value.

Abstract: A service providing device (400) includes: one-time PW generating processing section (435) which generates, for each operation device (300), authentication information for use in authentication processing carried out by the service providing device (400) in a case where the service providing device (400) is accessed by a display processing device (200); and an image data generating processing section (436) which (i) generates operation data including the authentication information generated and processing specifying information specifying the authentication processing, and (ii) transmits the operation data thus generated to the operation device (300).
