The control unit 21 also controls the wireless communication unit 22 to communicate wirelessly with the access point 3 and the smartphone 4.

[0019] The wireless communication unit 22 has an antenna and the like, and has a function of communicating via wireless LAN communication WC1 such as WiFi, and a function of communicating via short-range wireless communication WC2 such as Bluetooth (registered trademark) or ZigBee (registered trademark). The wireless communication unit 22 can communicate with the access point 3 via wireless LAN communication WC1 based on an instruction from the control unit 21. The wireless communication unit 22 can communicate with the wireless communication unit 42 of the smartphone 4 via short-range wireless communication WC2 based on an instruction from the control unit 21.

[0020] The recording unit 23 includes a recording medium such as a hard disk, a flash memory, etc. The recording unit 23 records a user authentication code 24, user-related information 25, and wireless connection information 26.

[0021] The user authentication code 24 is a unique code assigned to a user in the home system 100, and is a code for authenticating the user in the home system 100. The user authentication code 24 is, for example, a combination of a user ID and a password corresponding to the user ID, or a token generated based on the user ID.

[0022] User-related information 25 is information related to the user who uses household equipment 1. User-related information 25 includes the usage history (log) of household equipment 1 and status information that enables understanding of the usage status of consumables in household equipment 1. For example, the status information for faucet device 1A includes the amount of water used and the duration of use of faucet device 1A.

[0023] The wireless connection information 26 includes wireless connection information required for communicating with the access point 3 via the wireless LAN communication WC1, and is, for example, a combination of a WiFi SSID (Service Set Identifier) ​​and a password corresponding to the SSID.

[0024] The wireless connection information 26 includes wireless connection information necessary for communicating with the smartphone 4 via short-range wireless communication WC2, such as Bluetooth (registered trademark) pairing information.

[0025] [Access Point 3] The access point 3 is installed in the home HO and has a function of communicating via a wireless LAN communication WC1 such as WiFi. The access point 3 communicates with the control device 2 via the wireless LAN communication WC1. The access point 3 also relays communication with the control device 2 via the wireless LAN communication WC1 to the network NW via a gateway GW.

[0026] A plurality of access points 3 may be installed in the residence HO. When two access points 3 are installed in the residence HO and the two access points 3 are to be distinguished from one another, one is referred to as a first access point 3A and the other as a second access point 3B. The access point 3 may include a repeater 31 for wireless LAN communication WC1. The control device 2 may communicate with either the first access point 3A or the second access point 3B. Furthermore, the control device 2 may communicate with the access point 3 via the repeater 31.

[0027] The access point 3 has an SSID (Service Set Identifier) ​​which is an ID used for connection authentication etc. in the wireless LAN communication WC1. The access point 3 permits communication from the control device 2 through authentication using the SSID that the access point 3 has and the password corresponding to the SSID.

[0028] The access point 3 is capable of wireless communication using multiple communication methods, and a corresponding SSID is set for each communication method. For example, the access point 3 is capable of wireless communication using multiple frequency bands, and a corresponding SSID is set for each frequency band. In this embodiment, the access point 3 is capable of wireless communication in the 2.4 GHz band and the 5 GHz band, and has a first SSID corresponding to communication in the 2.4 GHz band and a second SSID corresponding to communication in the 5 GHz band. Two or more SSIDs that support different frequency bands generally have a high degree of similarity in the SSID character strings. For example, a first SSID corresponding to communication in the 2.4 GHz band has the letter "G," and a second SSID corresponding to communication in the 5 GHz band has the letter "A," and the character strings other than "G" and "A" in the two SSIDs are often the same. Note that the different frequency bands are not limited to the combination of the 2.4 GHz band and the 5 GHz band.

[0029] The two or more SSIDs possessed by the access point 3 are not limited to two or more SSIDs corresponding to different frequency bands. For example, if the access point 3 includes a first access point 3A and a second access point 3B, the two or more SSIDs possessed by the access point 3 may be a first SSID possessed by the first access point 3A and a second SSID possessed by the second access point 3B. For example, the first access point 3A is installed on the first floor of a residence HO, and the second access point 3B is installed on the second floor of the residence HO. If the first access point 3A and the second access point 3B are the same or similar models, the similarity between the character strings of the first SSID and the second SSID is high.

[0030] [Smartphone 4] FIG. 3 is a functional block diagram of the smartphone 4. The smartphone 4 is an example of a mobile terminal or a terminal device. The mobile terminal or the terminal device is not limited to the smartphone 4, and may be, for example, a mobile phone, a smart watch, a tablet terminal, a personal computer, etc. The smartphone 4 has a control unit 41, a wireless communication unit 42, a touch panel 43, and a camera 44.

[0032] The two or more SSIDs that the access point 3 has are not limited to two or more SSIDs that correspond to different frequency bands. For example, if two or more SSIDs are set for one frequency band in the access point 3, the two or more SSIDs that the access point 3 has may be two or more SSIDs that correspond to the same frequency band. For example, the two or more SSIDs that the access point 3 has may be a first SSID that corresponds to communication in the 2.4 GHz band that the first access point 3A has and a second SSID that corresponds to communication in the 2.4 GHz band that the second access point 3B has.

[0033] The wireless communication unit 42 has an antenna and the like, and has a function of communicating via short-range wireless communication WC2 such as Bluetooth (registered trademark) or ZigBee (registered trademark), and a function of communicating via high-speed wireless communication WC3 that can connect to a network NW according to a fourth-generation communication standard, a fifth-generation communication standard, or the like. The wireless communication unit 42 can communicate with the wireless communication unit 22 of the control device 2 via the short-range wireless communication WC2 based on instructions from the control unit 41. The wireless communication unit 42 can communicate with the device management server 5, the user management server 6, the EC server 7, and the call center server 8 via the high-speed wireless communication WC3 that is connected to a base station and the network NW based on instructions from the control unit 41.

[0034] The touch panel 43 is, for example, a capacitance type touch panel. An input operation input by a user to the touch panel is acquired by the control unit 41. The touch panel 43 displays a display screen based on an instruction from the control unit 41.

[0035] The smartphone 4 has installed thereon a smart home application AP, which is an application that provides comfortable and convenient functions to the user by utilizing the home equipment 1 connected to the network NW.

[0036] The smart home application AP can generate remote control instructions for the household equipment 1. The remote control instructions for the household equipment 1 are acquired by the device management server 5 via the network NW. The wireless communication unit 22 of the control device 2 acquires the remote control instructions for the household equipment 1 via the access point 3. The control unit 21 of the control device 2 controls the household equipment 1 based on the acquired control instructions. The user can remotely control the household equipment 1 using the smart home application AP whether they are at home or away from home.

[0037] [Device management server 5] The device management server 5 is configured, for example, by one or more servers and can be connected to a network NW. The server includes hardware such as a processor such as a CPU, memory, recording media such as a hard disk or flash memory, and communication devices. The functions of the device management server 5 are realized by a program executed on the server's processor. The server may be an on-site server, or a cloud server that provides IaaS (Infrastructure as a Service), PaaS (Platform as a Service), SaaS (Software as a Service), or the like, or a server that combines these. In the following description, "server" includes any of the above servers.

[0038] The device management server 5 is a server that manages the household equipment 1. The device management server 5 acquires control instructions for the household equipment 1 generated in the smart home application AP. The control instructions for the household equipment 1 are acquired by the control device 2. The device management server 5 records the control instructions for the household equipment 1 generated by the user as a control instruction history. The device management server 5 also acquires status information from the control device 2 that enables the usage status of consumables in the household equipment 1 to be understood. The device management server 5 records the control instruction history for the household equipment 1 and the status information of the household equipment 1 as user-related information.

[0039] [User management server 6] The user management server 6 is configured by, for example, one or more servers, and can be connected to a network NW. The functions of the user management server 6 are realized by a program executed in a processor of the server.

[0040] The user management server 6 is a server that manages the user authentication code 24. A user of the home system 100 can obtain the user authentication code 24 from the user management server 6. The user authentication code 24 obtained by the user is also recorded in the control device 2 and the device management server 5. The user authentication code 24 obtained by the user is also registered in the smart home application AP of the smartphone 4. A control instruction for the household equipment 1 generated by the user in the smart home application AP is obtained by the device management server 5 and the control device 2 that are associated based on the user authentication code 24.

[0041] [EC Server 7] The EC (Electronic Commerce) server 7 is configured by, for example, one or more servers and can be connected to a network NW. The functions of the EC server 7 are realized by a program executed in a processor of the server.

[0042] The EC server 7 is a server that can order consumables for the household equipment 1. A user can order consumables for the household equipment 1 using the website of the EC server 7.

[0043] [Call Center Server 8] The call center server 8 is configured by, for example, one or more servers and is connectable to a network NW. The functions of the call center server 8 are realized by a program executed in a processor of the server.

[0044] The call center server 8 is a server installed at the call center of the home appliance 1. The call center is an equipment supplier that receives inquiries about the home appliance 1 from users by telephone, etc. The call center server 8 acquires the usage history (log) of the home appliance 1 via the network NW. When responding to inquiries by phone from users, the call center operator uses the usage history (log) acquired by the call center server 8.

[0045] Two or more of the device management server 5, user management server 6, EC server 7, and call center server 8 may be the same server.

[0046] Next, a description will be given of the operation of the home system 100. Hereinafter, the operation of the control device 2 will be described with reference to the control flowchart of the control unit 21 of the control device 2 shown in FIG.

[0047] Assume that a water faucet device 1A and a control device 2, which are household equipment 1, are installed in a home HO, and a microwave oven is installed near the water faucet device 1A. A combination of a first SSID and a first password, which is a password corresponding to the first SSID, is recorded in a recording unit 23 of the control device 2 as wireless connection information 26. The control device 2 is configured to connect to an access point 3 using the first SSID. When a user uses the microwave oven, the 2.4 GHz band wireless communication corresponding to the first SSID may become unstable because the microwave oven uses electromagnetic waves in the 2.4 GHz band.

[0048] In step S110, control unit 21 determines whether the SSID (destination) of access point 3 needs to be switched. For example, control unit 21 determines that the SSID needs to be switched when wireless communication with access point 3 using the first SSID is down. Control unit 21 also determines that the SSID needs to be switched when wireless communication with access point 3 using the first SSID becomes unstable. For example, when a user uses a microwave oven, wireless communication in the 2.4 GHz band becomes unstable, and wireless communication with access point 3 using the first SSID becomes unstable. In this case, control unit 21 determines that the SSID (destination) of access point 3 needs to be switched. When control unit 21 determines that the SSID (destination) of access point 3 needs to be switched, it next executes step S120.

[0049] In step S120, the control unit 21 controls the wireless communication unit 22 to search for nearby access points 3 and scan for recognizable SSIDs.

[0050] In step S130, the control unit 21 selects an SSID that is highly similar to the first SSID from among the SSIDs recognized by the scan. In this embodiment, since the similarity between the character strings of the first SSID and the second SSID is high, the second SSID that corresponds to a different frequency band from the first SSID is selected as the SSID with the highest similarity.

[0051] In step S140, control unit 21 attempts wireless communication with access point 3 having the second SSID using the second SSID and the first password. Here, the first password is a password corresponding to the first SSID and is recorded in recording unit 23. If the wireless communication is successful, control unit 21 then executes step S150. If the wireless communication is not successful, control unit 21 executes step S120 again.

[0052] In step S150, control unit 21 records the combination of the second SSID and the first password in recording unit 23 as wireless connection information 26 that can connect to access point 3. Even when the microwave oven is in operation, control device 2 can stably communicate with access point 3 via wireless communication in the 5 GHz band that corresponds to the second SSID.

[0053] According to the home system 100 of this embodiment, when the connection settings with the access point 3 that supports multiple communication methods are insufficient, the control device 2 can preferably connect to the access point 3 without a user instruction. When only the first SSID is recorded as the wireless connection information 26 in the recording unit 23 of the control device 2, wireless communication using the second SSID can be attempted depending on the situation. Furthermore, when wireless communication using the second SSID is successful, the control device 2 records the second SSID in the recording unit 23 as the wireless connection information 26 that allows connection to the access point 3.

[0054] While one embodiment of the present disclosure has been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment and includes design modifications within the scope of the present disclosure. Furthermore, the components shown in the above-described embodiment and modifications can be configured in any suitable combination.

[0055] The programs for the control device 2 and other devices are recorded on a computer-readable recording medium. The programs recorded on the recording medium are loaded into a computer system and executed. The term "computer system" as used herein includes hardware such as an operating system (OS) and peripheral devices. Furthermore, "computer-readable recording medium" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, as well as storage devices such as hard disks built into a computer system. Furthermore, "computer-readable recording medium" may also include devices that dynamically store programs for a short period of time, such as communication lines used when transmitting programs over a network such as the Internet or a telephone line, or devices that store programs for a fixed period of time, such as volatile memory within a computer system that serves as a server or client. The programs may be designed to implement some of the functions described above, or may be capable of implementing the functions in combination with programs already stored in the computer system, or may be implemented using a programmable logic device such as an FPGA (Field Programmable Gate Array).
