  • Publication number: 20250119366
    Abstract: An information management method collects log information of one or more home electrical apparatuses corresponding to service providers. Display screen data is generated which indicates a status of the log information. The display screen data includes groups of information which each contain information on an apparatus, a service provider corresponding to the apparatus, and log information output from the apparatus. Provision of the log information of each group is individually selectable. The display screen data is provided via a network to a display terminal that performs access to a server device. Information is received from the display terminal, which indicates that selection on whether or not provision of the log information is performed. Provision of the log information is not performed on the selected group when a determination is made that refusal of provision of the log information on the selected group is performed.

    Abstract: A relay device relays communication. The relay device includes: a receiving unit that receives communication data from a communication device; a storage unit that stores the communication data received by the receiving unit; and a processing unit that performs processing. A first period and a second period are alternately set. The processing unit changes the total number of the first periods and the second periods included in a next predetermined period each time a predetermined period including the first periods and the second periods passes. The processing unit determines whether or not the communication data is stored in the storage unit.
