Abstract: A power management apparatus includes a management unit configured to manage data of output power output from a distributed power supply provided in a predetermined facility, a detection unit configured to detect that a user having the distributed power supply is present in a visit space other than the predetermined facility, and a control unit configured to perform, when the user is present in the visit space, interchange processing of providing the output power to the visit space based on the data of the output power

Abstract: A power management apparatus includes a management unit configured to manage data of output power output from a distributed power supply provided at a predetermined facility, a detection unit configured to detect that a user in possession of the distributed power supply is present in a visit space other than the predetermined facility, and a control unit configured to perform, when the user is present in the visit space, interchange processing of providing the output power to the visit space based on the data of the output power. The interchange processing includes processing of supplying electric power to the user in the visit space.

Abstract: Even when a user wants to easily operate a plurality of load devices in his or her home using an information terminal device, dedicated application software needs to be started for each load device, which makes the operation complex. A device controller capable of controlling a plurality of load devices, includes: a controller; and a display unit having a first screen and a second screen, wherein the controller is configured to cause the display unit to display, in the first screen, a selection object that instructs a user to select at least one of the plurality of load devices and a first operation object that instructs a user to perform a first type of operation relating to the plurality of load devices, and display, in the second screen, a second operation object including a second type of operation not included in the first operation object.
