[0012] A home system 100 according to one embodiment of this disclosure will be described with reference to Figures 1 to 4.

[0013] [Home System 100] The home system 100 comprises a terminal device 1, residential equipment 2, and an access point 3. The home system 100 is a system installed in a building area R1 such as a residence. The building area R1 includes not only buildings used for residential purposes, but also buildings not used for residential purposes such as offices, schools, and hospitals. Furthermore, the building area R1 broadly includes various care facilities, commercial facilities, and public facilities. The building area R1 is an example of a "facility."

[0014] The home system 100 is connected to a network NW. The network NW may be a wide area network (WAN) such as the Internet, a private network (LAN) within the building where the home system 100 is installed, or a combination of the two.

[0015] [Terminal device 1] Terminal device 1 is, for example, a mobile device such as a smartphone. Terminal device 1 is not limited to a smartphone, but may also be a mobile phone, smartwatch, tablet device, personal computer, etc. Terminal device 1 comprises a control unit 11, a wireless communication unit 12, and a touch panel 13.

[0016] The control unit 11 is a program-executable computer having a processor such as a CPU, a memory capable of reading programs, a storage unit capable of storing programs and data, and an input / output control unit. The functions of the control unit 11 are realized by the processor executing programs provided to the control unit 11. Programs provided to the control unit 11 are also called applications. The control unit 11 controls the wireless communication unit 12 and the touch panel 13.

[0017] The wireless communication unit 12 (corresponding to the communication unit) has an antenna and the like, and can communicate with the access point 3 by wireless communication WC1 such as wireless LAN like WiFi. The wireless communication unit 12 can communicate with the home equipment 2 by short-range wireless communication WC2 such as Sub-GHz, Bluetooth (registered trademark), ZigBee (registered trademark), NFC (Near field communication).

[0018] The touch panel 13 (corresponding to the display unit) is, for example, a capacitive touch panel. Input operations entered by the user on the touch panel are acquired by the control unit 11. The touch panel 13 displays a display screen based on an instruction from the control unit 11.

[0019] [Home equipment 2] The home equipment 2 includes an equipment device 21 and a control device 22. The equipment device 21 and the control device 22 may be integrally configured or may be provided separately as different devices.

[0020] The home equipment 2 is a device installed as equipment in the building area R1. The home equipment 2 is an example of "facility equipment" installed as equipment in a facility. The facility equipment includes building equipment in a building (for example, a building) not used for residence. Also, the facility equipment includes not only equipment installed in the facility but also equipment installed in the site where the facility is located.

[0021] The equipment device 21 is, for example, a camera such as an indoor camera or an outdoor camera. The equipment device 21 is not limited to a camera and may be building materials such as a shutter, a front door, or a front door lock, may be home appliances such as an air conditioner, a lighting device, or a remote control device, or may be an energy management device such as a distribution board or a solar power generation device. The equipment device 21 may include sensors such as a humidity and temperature sensor or a human presence sensor, and a relay device that relays the connection between these sensors and the access point 3.

[0022] The control device 22 controls the operation of the facility device 21. The control device 22 is a program-executable computer having a processor such as a CPU, a memory capable of loading a program, a storage unit capable of storing a program and data, and an input / output control unit. The functions of the control device 22 are realized by the processor executing the program provided to the control device 22.

[0023] The control device 22 has an antenna and the like, and can communicate with the terminal device 1 by short-range wireless communication WC2 such as Sub-GHz, Bluetooth (registered trademark), ZigBee (registered trademark), NFC (Near field communication). The control device 22 can communicate with the access point 3 by wireless communication WC3 such as wireless LAN like WiFi.

[0024] [Access Point 3] The access point 3 is installed in the building area R1 and has a function of communicating by wireless communications WC1 and WC3 such as WiFi. The access point 3 communicates with the terminal device 1 by wireless communication WC1. The access point 3 communicates with the control device 22 by wireless communication WC3. Also, the access point 3 relays the communications by wireless communications WC1 and WC3 to the network NW via the gateway GW.

[0025] The access point 3 has an SSID (Service Set Identifier) which is an ID used for connection authentication and the like in wireless communications WC1 and WC3. The access point 3 permits communications from the terminal device 1 and the control device 22 by authentication using the SSID possessed by the access point 3 and the password corresponding to the SSID.

[0026] Access point 3 is capable of wireless communication using multiple communication methods, and a corresponding SSID is set for each communication method. For example, 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, access point 3 is capable of wireless communication in the 2.4GHz band and the 5GHz band.

[0027] Two or more SSIDs that support different frequency bands generally have a high degree of similarity in their SSID name strings. For example, an SSID name supporting 2.4GHz band communication may contain the letter "g", and an SSID name supporting 5GHz band communication may contain the letter "a", and in many cases the other characters in the two SSIDs are the same. In this embodiment, a string refers to a sequence of letters, numbers, hiragana, katakana, kanji, or symbols.

[0028] Furthermore, for example, an SSID name supporting 2.4GHz band communication will contain the characters "2.4G," and an SSID name supporting 5GHz band communication will contain the characters "5G," and in many cases, the characters other than "2.4G" and "5G" are the same for both SSIDs. Note that the two different frequency bands are not limited to a combination of 2.4GHz and 5GHz bands.

[0029] In this embodiment, the first and third SSIDs shown in Figure 3 are SSIDs that support communication in the 2.4GHz band, and the second and fourth SSIDs shown in Figure 3 are SSIDs that support communication in the 5GHz band.

[0030] Access point 3 does not need to have all of the SSIDs shown in Figure 3 configured. For example, it may have the first and second SSIDs, or the third and fourth SSIDs, configured out of the four SSIDs shown in Figure 3.

[0031] Terminal device 1 is connected to access point 3 via wireless communication WC1, and to the network NW via access point 3. Terminal device 1 also has the function of connecting to the network NW via high-speed wireless communication such as 4th generation or 5th generation communication standards.

[0032] Terminal device 1 has a smart home application installed, which is an application that provides comfortable and convenient functions to the user by utilizing residential equipment 2 connected to the network NW.

[0033] The smart home application can generate remote control instructions for the home equipment 2. These remote control instructions for the home equipment 2 are transmitted to the access point 3 via the network NW, and then transmitted to the control device 22 via the access point 3. The control device 22 controls the equipment 21 based on the received control instructions. The user can remotely operate the home equipment 2 using the smart home application, whether they are at home or away. Alternatively, the remote control instructions for the home equipment 2 transmitted from the smart home application may be acquired by a device management server connected to the network NW, and then transmitted from the device management server to the control device 22 via the network NW and access point 3.

[0034] When using the home system 100, the user first performs the initial setup to connect the residential equipment 2 and the access point 3 via wireless communication WC3. This initial setup connects the residential equipment 2 and the access point 3, and the residential equipment 2 is then connected to the network NW via the access point 3.

[0035] Here, for example, the residential equipment 2 may have a limited range of compatible SSID frequency bands. In this embodiment, residential equipment 2 supports SSIDs in the 2.4GHz band but does not support SSIDs in the 5GHz band.

[0036] Home equipment 2 may not be able to connect to SSIDs in unsupported frequency bands. Furthermore, if home equipment 2 is connected to an SSID in an unsupported frequency band, it may not be able to receive remote control commands via the network NW. Therefore, when connecting home equipment 2 and access point 3 via wireless communication WC3, the user must set the SSID to one in a frequency band supported by home equipment 2.

[0037] When a user connects the home equipment 2 to the access point 3, the terminal device 1 and the access point 3 are connected via wireless communication WC1. The terminal device 1 and the home equipment 2 are also connected via short-range wireless communication WC2. For example, the user operates a smart home application installed on the terminal device 1 using the touch panel 13 to configure the connection between the home equipment 2 and the access point 3.

[0038] When a user configures the connection between the residential equipment 2 and the access point 3, they input the SSID information of the wireless communication WC1, which the terminal device 1 and the access point 3 are communicating with, into the terminal device 1. SSID information includes, for example, the SSID name and the password corresponding to that SSID name. The residential equipment 2 obtains the SSID information from the terminal device 1 and uses the obtained SSID information to communicate with the access point 3.

[0039] In the following explanation, among the multiple SSIDs set on access point 3, the SSID that home equipment 2 supports will be referred to as the "correct SSID," and the SSID that home equipment 2 does not support will be referred to as the "incorrect SSID." Furthermore, among the multiple SSIDs set on access point 3, the SSID that terminal device 1 uses to communicate with access point 3 when setting up the connection between home equipment 2 and access point 3 will be referred to as the "connected SSID."

[0040] When the user configures the connection between the home equipment 2 and the access point 3, they input the SSID information of the connection SSID into the smart home application, for example, by entering the password for the connection SSID displayed on the touch panel 13. The terminal device 1 transmits the entered SSID information of the connection SSID to the home equipment 2.

[0041] If the SSID information obtained from terminal device 1 is the correct SSID, the residential equipment 2 can connect to access point 3 using the obtained correct SSID. If the connection SSID set by the user is an incorrect SSID, terminal device 1 will notify the user accordingly.

[0042] Using Figure 4, we will explain a notification method in which, when connecting residential equipment 2 and access point 3 via wireless communication WC3, the connection SSID set by the user is incorrect, and the terminal device 1 notifies the user that the connection SSID is incorrect. In the following explanation, the correct SSID that residential equipment 2 corresponds to is an SSID in the 2.4GHz band.

[0043] [Step S1] When configuring the connection between the residential equipment 2 and the access point 3, the control unit 11 performs step S1 (acquisition determination step). In step S1, the control unit 11 determines whether or not it is possible to acquire the frequency band of the connected SSID.

[0044] Some smartphones and other terminal devices can acquire the frequency band of the connected SSID to the access point, while others cannot. Furthermore, depending on the terminal device's settings, it may not be possible to acquire the frequency band of the connected SSID.

[0045] When the control unit 11 determines that it can acquire the frequency band of the connected SSID to which the wireless communication unit 12 and the access point 3 are connected, it proceeds to step S2. When the control unit 11 determines that it cannot acquire the frequency band of the connected SSID to which the wireless communication unit 12 and the access point 3 are connected, it proceeds to step S3. Step S3 will be described later.

[0046] [Step S2] In step S2 (frequency acquisition step), the control unit 11 acquires the frequency band of the connected SSID to which the wireless communication unit 12 and the access point 3 are connected. In step S2, the control unit 11 may acquire the frequency of the connected SSID.

[0047] [Step S4] Next, the control unit 11 performs step S4 (determination step). In step S4, the control unit 11 compares the frequency of the connected SSID obtained in step S2 with a predetermined frequency band and determines whether or not the frequency of the connected SSID is included in the predetermined frequency band. Here, the frequency of the connected SSID may include the frequency band of the connected SSID.

[0048] The predetermined frequency band is the frequency band of the positive SSID to which the residential equipment 2 corresponds. As described above, the frequency band of the positive SSID in this embodiment is the 2.4 GHz band.

[0049] The control unit 11 proceeds to step S5 when it determines that the frequency of the connected SSID is included in a predetermined frequency band. In other words, the control unit 11 proceeds to step S5 when it determines that the connected SSID is the primary SSID. For example, the control unit 11 proceeds to step S5 when the connected SSID is the primary SSID in the 2.4GHz band.

[0050] The control unit 11 proceeds to step S6 when it determines that the frequency of the connected SSID is not included in a predetermined frequency band. In other words, the control unit 11 proceeds to step S6 when it determines that the connected SSID is an incorrect SSID. For example, the control unit 11 proceeds to step S6 when the connected SSID is a second SSID in the 5GHz band. Step S6 will be described later.

[0051] [Step S5] In step S5 (setting step), the control unit 11 transmits the SSID information of the connected SSID obtained in step S2 to the residential equipment 2. The control unit 11, for example, obtains the SSID information of the connected SSID before executing step S1.

[0052] The residential equipment 2 can communicate with the access point 3 using the acquired SSID information, thereby enabling communication with the access point 3 using the connection SSID, which is the frequency band supported by the residential equipment 2.

[0053] In step S2 described above, if the control unit 11 determines that it is not possible to obtain the frequency band of the connected SSID to which the wireless communication unit 12 and the access point 3 are connected, it proceeds to step S3.

[0054] [Step S3] In step S3 (SSID name acquisition step), the control unit 11 acquires the SSID name of the connected SSID to which the wireless communication unit 12 and the access point 3 are connected.

[0055] [Step S7] Next, the control unit 11 performs step S7 (determination step). In step S7, the control unit 11 determines whether or not a predetermined string is included in the SSID name of the connected SSID obtained in step S3.

[0056] In this embodiment, the primary SSID that the residential equipment 2 corresponds to is a 2.4GHz band SSID. Therefore, in step S7, the control unit 11 determines whether the SSID name of the connected SSID contains a string that can be estimated to be a 2.4GHz band SSID.

[0057] For example, the control unit 11 determines whether the SSID name of the connected SSID contains "-g" or "2.4G". If the SSID name of the connected SSID contains a predetermined string, the control unit 11 determines that the connected SSID is a valid SSID and proceeds to step S5.

[0058] If the SSID name contains "-g" or "2.4G", it can be estimated that the SSID is likely to be in the 2.4GHz band. In step S5, the control unit 11 transmits the SSID information of the connected SSID that was determined to contain a predetermined string in step S7 to the residential equipment 2. As a result, the residential equipment 2 can communicate with the access point 3 using the positive SSID of the 2.4GHz band that the residential equipment 2 corresponds to.

[0059] In step S7, if the control unit 11 determines that the connected SSID is an incorrect SSID when the SSID name of the connected SSID obtained in step S3 does not contain a predetermined string, it proceeds to step S6. Also, in step S4, if the control unit 11 determines that the frequency of the connected SSID obtained in step S2 is not included in a predetermined frequency band, it proceeds to step S6.

[0060] [Step S6] In step S6 (notification step), the control unit 11 notifies the user that the connection SSID that the terminal device 1 is using to communicate with the access point 3 is an incorrect SSID that is not supported by the residential equipment 2.

[0061] For example, when terminal device 1 is connected to access point 3, the connection SSID is the second SSID shown in Figure 3, and the SSID name does not contain "-g". Therefore, the connection SSID is likely to be in a different frequency band than the 2.4GHz band. In this case, the control unit 11 notifies the user that the connection SSID is an incorrect SSID.

[0062] Furthermore, if the frequency of the connected SSID obtained in step S2 is not included in the 2.4GHz band, the control unit 11 notifies the user that the connected SSID is an incorrect SSID.

[0063] The control unit 11 controls the touch panel 13 and displays an image on the touch panel 13 indicating that the connected SSID is an incorrect SSID, thereby notifying the user that the connected SSID is an incorrect SSID. If the terminal device 1 is equipped with a speaker, the control unit 11 may also control the speaker and play an audio message from the speaker indicating that the connected SSID is an incorrect SSID, thereby notifying the user that the connected SSID is an incorrect SSID.

[0064] For example, if a home appliance and an access point are connected using an incorrect SSID, problems may arise such as the user being unable to remotely control the appliance despite the connection. It is difficult for users to identify the cause of such problems. When such problems occur, users may try to resolve the issue by contacting the seller or manufacturer of the appliance. Furthermore, some users may repeatedly connect their appliances and access points using the incorrect SSID without immediately contacting the seller or manufacturer, potentially perpetuating the incorrect connection. Therefore, it is necessary to identify the cause of the problem as soon as possible and for users to understand the cause of the problem.

[0065] The control unit 11 notifies the user if the connection SSID is incorrect before transmitting the SSID information of the connection SSID to the home equipment 2. This prevents the home equipment 2 and access point 3 from being connected using the incorrect SSID. When the user is notified that the connection SSID is incorrect, they can change the connection SSID to the correct SSID and use the correct SSID to configure the connection between the home equipment 2 and access point 3, thereby properly configuring the connection settings for the home equipment 2.

[0066] In this way, users can become aware of errors such as selecting the wrong SSID as the connection SSID without having to contact the seller or manufacturer of the home equipment 2. By preventing malfunctions that are difficult for users to resolve themselves, the convenience of the home system 100 can be improved. In addition, users will no longer need to contact the seller or manufacturer of the home equipment, reducing the effort required from the user and the operational costs for the seller or manufacturer.

[0067] In step S6, terminal device 1 may notify the user that the connected SSID is an incorrect SSID and provide the user with reference information to help the user set the correct SSID as the connected SSID. For example, terminal device 1 may prompt the user to set an SSID whose SSID name includes "-g" or "2.4G" as the connected SSID.

[0068] In this case, terminal device 1 may estimate the name of the correct SSID from the SSID name of the incorrect SSID set by the user as the connection SSID, and display the estimated SSID name on the touch panel 13.

[0069] For example, the control unit 11 displays the following message on the touch panel 13: "Failure to configure the wireless LAN connection settings for the residential equipment 2. Please connect (the SSID name estimated to be the correct SSID) to the terminal device 1 and then try configuring again."

[0070] For example, the control unit 11 displays on the touch panel 13 a string obtained by removing "-a" or "-5G" from the end of the SSID name of an incorrect SSID set by the user as the connection SSID, and then adding "-g" or "-2.4G" to the end of that string, as the SSID name estimated to be the correct SSID.

[0071] When notifying the user that the connected SSID is incorrect, the system informs the user of the SSID name that is presumed to be the correct SSID. This allows the user to infer which SSID should be set as the connected SSID on terminal device 1. As a result, the convenience of the home system 100 can be further improved.

[0072] In step S6, the control unit 11 notifies the user that the connected SSID is an incorrect SSID and terminates the operation shown in Figure 4. The user, having been notified that the connected SSID is an incorrect SSID, changes the SSID to which the terminal device 1 and access point 3 are connected to a different SSID, and then has the control unit 11 perform the operation shown in Figure 4 again.

[0073] In step S5, the control unit 11 transmits the SSID information of the positive SSID to the residential equipment 2 and terminates the operation shown in Figure 4.

[0074] Note that the frequency band of the SSID supported by residential equipment 2 is not limited to the 2.4GHz band. The correct SSID mentioned above is simply any SSID that residential equipment 2 should connect to access point 3 with, and the incorrect SSID mentioned above is simply any SSID with a different frequency band than the correct SSID.

[0075] According to the home system 100 of this embodiment, when it is determined that the SSID used for communication between the terminal device 1 and the access point 3 is different from the SSID of the frequency band supported by the residential equipment 2, the system can improve the convenience of setting up an internet connection by notifying the user that the SSID is incorrect.

[0076] Although embodiments of this disclosure have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments and may include design changes and the like that do not depart from the gist of this disclosure. The components shown in the embodiments described above and the modifications shown below can be combined as appropriate.

[0077] The programs for terminal device 1 and residential equipment 2 are recorded on a computer-readable recording medium. The programs recorded on this recording medium are loaded into a computer system and executed. Here, "computer system" includes hardware such as the OS and peripheral devices. Furthermore, "computer-readable recording medium" refers to portable media such as flexible disks, magneto-optical disks, ROMs, and CD-ROMs, as well as storage devices such as hard disks built into the computer system. In addition, "computer-readable recording medium" may also include those that dynamically hold programs for a short period of time, such as communication lines used when transmitting programs via networks such as the Internet or communication lines such as telephone lines, and those that hold programs for a certain period of time, such as volatile memory inside the computer system that acts as a server or client in such cases. Furthermore, the above programs may be for the purpose of realizing some of the functions described above, or they may be able to realize the above functions in combination with programs already recorded in the computer system, or they may be realized using programmable logic devices such as FPGAs (Field Programmable Gate Arrays).
