[0033] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide examples of the present application. However, the present application may be implemented in many different forms and is not limited to the examples described herein. Rather, these examples are provided to make the disclosure of the present application more thorough and comprehensive.

Furthermore, the term "and / or" as used in this specification includes any and all combinations of the relevant listed items.

[0039] The remote control terminal involved in this application can be any type of terminal device that can control a water heater, such as a bathroom controller, a mobile terminal, etc. In order to facilitate the user to control the water heater, a corresponding control APP can also be configured on the remote control terminal. In order for the remote control terminal to control a specific water heater, it is necessary to first pair the remote control terminal with the water heater. Research has found that the current pairing method between water heaters and remote control terminals on the market is relatively cumbersome and has a low success rate. User pairing generally requires operating the product and the mobile phone APP, and it takes about 2 minutes to complete the pairing. Incorrect pairing steps during the process will lead to pairing failure.

[0040] Based on the above reasons, the present invention provides a method for pairing a remote control terminal with a water heater. Figure 1 First, the pairing method between the remote control terminal and the water heater is described from the remote control terminal side, including step S102 and step S104.

[0041] S102, when establishing a first communication connection with the water heater, the first remote control terminal sends the device information of the first remote control terminal to the water heater, receives the device information sent by the water heater and the network configuration information of the routing device, and uses the device information sent by the water heater as the main device information.

[0042] The first remote control terminal is the remote control terminal to be paired with the water heater. It is understood that the first communication connection can be a common wireless communication connection method such as WiFi, Bluetooth, or LoRa. Both the water heater and the remote control terminal are equipped with a WiFi module, which can be set to AP (Access Point) mode or STA (Station) mode. When the water heater or remote control terminal is in AP mode, devices equipped with a WiFi module can access the water heater or remote control terminal in STA mode. When the water heater or remote control terminal is in STA mode, the water heater or remote control terminal can also access devices in AP mode. To facilitate the water heater to record and verify the identity of the first remote control terminal, when the water heater and the first remote control terminal establish a first communication connection, the first remote control terminal sends its device information to the water heater. Since the water heater is already connected to a routing device, the routing device's network configuration information (such as the routing device's name, account number, and password) is stored in the water heater. To avoid the user having to use a mobile phone or other device to enter the routing device's network configuration information into the first remote control terminal, the first remote control terminal can automatically receive the routing device's network configuration information sent by the water heater. Similarly, to facilitate recording and verifying the identity of the water heater to be paired, when the water heater establishes a first communication connection with the first remote control terminal, the first remote control terminal receives the device information of the water heater sent by the water heater and uses the received device information of the water heater as the master device information. The first remote control terminal can then verify the identity of the water heater using the master device information.

[0043] S104: The first remote control terminal accesses the routing device in STA mode according to the network configuration information of the routing device.

[0044] It is understood that devices in STA mode can access the router using the router's network configuration information. Devices connected to the router can interact with each other using the local area network. If the router is connected to the internet, devices connected to the router can also interact with the cloud.

[0045] S106: After accessing the routing device, the first remote control terminal obtains first information and performs a first verification to pair with the water heater.

[0046] Among them, the first information includes the device information of the water heater connected to the routing device, and the first verification includes determining whether the first information matches the main device information. It can be understood that the remote control terminal and the water heater need to verify each other, and the pairing is successful after the verifications performed by both parties are passed. Since the water heater connected to the routing device and the water heater that establishes the first communication connection with the first remote control terminal may be different, the first remote control terminal needs to perform the first verification. In the case where the routing device is only connected to one water heater, the water heater connected to the routing device sends its own device information to the first remote control terminal through the transit of the routing device. The first remote control terminal verifies whether the device information of the water heater obtained through the transit of the routing device matches the main device information. If they match, the first verification performed by the first remote control terminal passes.

[0047] In the case where the routing device is connected to multiple water heaters, each water heater connected to the routing device sends its own device information to the first remote control terminal through the routing device. The first remote control terminal verifies whether there is one of the device information of the multiple water heaters obtained through the routing device that matches the main device information. If there is a match, the first verification performed by the first remote control terminal is successful.

[0048] After being connected to the routing device, the water heater can also send its own device information to the routing device. The routing device stores the device information of the water heater. The first information obtained by the first remote control terminal can also be read from the routing device.

[0049] Based on the pairing method of the remote control terminal and the water heater in this embodiment, the first remote control terminal to be paired with the water heater establishes a first communication connection with the water heater that has been connected to the routing device to interact with the water heater and obtain the network configuration information of the routing device required to access the routing device. The first remote control terminal and the water heater further exchange information for identity authentication for subsequent pairing verification. The first remote control terminal can access the routing device using the obtained network configuration information of the routing device and perform a first verification to attempt to pair with the water heater connected to the routing device. The remote control terminal does not require the assistance of additional communication equipment in the process of pairing with the water heater, and the user is also exempted from the complicated process of entering the network configuration information of the routing device, which greatly speeds up the pairing speed of the remote control terminal and the water heater and improves the pairing success rate.

[0050] In one embodiment, the first communication connection is a WIFI hotspot connection, see Figure 2 The method for pairing the remote control terminal with the water heater includes steps S202 to S210.

[0051] S202: The first remote control terminal waits for access in AP mode.

[0052] It can be understood that the first remote control terminal sets the WiFi module to AP mode and transmits a WiFi signal to wait for the device to access.

[0053] S204: After being connected to the water heater, the first remote control terminal establishes a first communication connection with the water heater.

[0054] The water heater obtains a first signal strength, identifies the target first remote terminal based on the first signal strength, and then connects to the target first remote terminal in STA mode. The first signal strength is the signal strength of the first remote terminal in AP mode. Specifically, the water heater obtains the strength of the WiFi signal transmitted by the first remote terminal in AP mode. If the first signal strength meets the communication requirements, the water heater determines that the first remote terminal corresponding to the first signal strength is the target first remote terminal. For example, the communication requirements may be considered met if the first signal strength exceeds a first threshold. To save energy, the water heater may obtain the first signal strength at preset intervals. To speed up the communication connection, the water heater may continuously obtain the first signal strength and connect to the target first remote terminal as soon as it is identified. If the water heater is currently connected to the routing device in STA mode, it should exit the routing device and connect to the target first remote terminal in STA mode. After connecting to the target first remote terminal in STA mode, the water heater establishes a first communication connection with the target first remote terminal.

[0055] S206, when the first remote control terminal establishes a first communication connection with the water heater, the first remote control terminal sends the device information of the first remote control terminal to the water heater, and receives the device information sent by the water heater and the network distribution information of the routing device, and uses the device information sent by the water heater as the main device information.

[0056] Step S206 is the same as step S102 and reference may be made to the above.

[0057] S208: The first remote control terminal accesses the routing device in STA mode according to the network configuration information of the routing device.

[0058] It can be understood that after establishing the first communication connection with the water heater and completing the interaction, the first remote control terminal will switch the mode of the WiFi module from AP mode to STA mode and access the routing device in STA mode.

[0059] S210: After accessing the routing device, the first remote control terminal obtains first information and performs a first verification to pair with the water heater.

[0060] Step S210 is the same as step S106 , and reference may be made to the above.

[0061] In one embodiment, when a first remote control terminal establishes a first communication connection with multiple water heaters, the step of using device information transmitted by the water heaters as primary device information includes: the first remote control terminal responding to a selection instruction and using the device information transmitted by the water heater corresponding to the selection instruction as the primary device information. It is understood that multiple water heaters may be within the signal coverage range of the first remote control terminal, and therefore, accessing the first remote control terminal requires determining one of the multiple water heaters with which the first communication connection has been established as a subsequent pairing target. In this embodiment, the first remote control terminal responds to the selection instruction and uses the device information transmitted by the water heater corresponding to the selection instruction as the primary device information, and subsequently uses the water heater corresponding to the selection instruction as the pairing target. Specifically, the selection instruction can be generated by a user operating the first remote control terminal. When the first remote control terminal establishes a first communication connection with multiple water heaters, the first remote control terminal displays the device information of each water heater on a display device. The user can select a pairing target for the first remote control terminal based on the content displayed on the display device. The first remote control terminal generates the selection instruction based on the user's operation.

[0062] See also Figure 3 The embodiment of the present invention further proposes a method for pairing an unpaired remote control terminal with a water heater through a paired remote control terminal. The method is described from the remote control terminal side and includes steps S302 to S306.

[0063] S302, when the first remote control terminal establishes a second communication connection with the second remote control terminal, receives the device information of the second remote control terminal, the network configuration information of the routing device, and the device information of the water heater paired with the second remote control terminal sent by the second remote control terminal, and uses the device information of the water heater paired with the second remote control terminal sent by the second remote control terminal as the main device information.

[0064] The first remote control terminal is the remote control terminal to be paired with the water heater, and the second remote control terminal is the remote control terminal already paired with the water heater. It is understood that the second communication connection can be a common wireless communication connection method such as WiFi, Bluetooth, or LoRa. The second remote control terminal has already been paired with the water heater and therefore stores the network configuration information of the routing device. To eliminate the need for the user to input the routing device network configuration information into the first remote control terminal using a mobile phone or other device, the first remote control terminal can automatically receive the routing device network configuration information sent by the second remote control terminal. Furthermore, since the first remote control terminal is to be paired with the water heater corresponding to the second remote control terminal, the first remote control terminal is equivalent to a subordinate device of the second remote control terminal. Therefore, the device information of the water heater already paired with the second remote control terminal is required to verify whether the water heater to be paired with it is the water heater paired with its superior. Furthermore, when verifying the identity of the first remote control terminal being paired through the second remote control terminal, the water heater needs to ensure that the superior of the first remote control terminal is a remote control terminal with which it has already been paired. Therefore, the first remote terminal also needs to receive the device information of the second remote control terminal sent by the second remote control terminal in order to verify the identity of the first remote control terminal.

[0065] S304: The first remote control terminal accesses the routing device in STA mode according to the network configuration information of the routing device.

[0066] S306: After accessing the routing device, the first remote control terminal obtains second information and performs a second verification to pair with the water heater.

[0067] Among them, the second information includes the device information of the water heater connected to the routing device, and the second verification includes determining whether the second information matches the main device information. It can be understood that the remote control terminal and the water heater need to verify each other, and the pairing is successful after the verifications performed by both parties are passed. Since the water heater connected to the routing device and the water heater paired with the superior of the first remote control terminal may be different, the first remote control terminal needs to perform a second verification. In the case where there is only one water heater connected to the routing device, the water heater connected to the routing device sends its own device information to the first remote control terminal through the transit of the routing device. The first remote control terminal verifies whether the device information of the water heater obtained through the transit of the routing device matches the main device information. If they match, the second verification performed by the first remote control terminal passes.

[0068] In the case where the routing device is connected to multiple water heaters, each water heater connected to the routing device sends its own device information to the first remote control terminal through the relay of the routing device. The first remote control terminal verifies whether there is one of the device information of the multiple water heaters obtained through the relay of the routing device that matches the main device information. If there is a match, the second verification performed by the first remote control terminal passes.

[0069] After being connected to the routing device, the water heater can also send its own device information to the routing device. The routing device stores the device information of the water heater. The first information obtained by the first remote control terminal can also be read from the routing device.

[0070] Based on the pairing method of the remote control terminal and the water heater in this embodiment, the first remote control terminal to be paired with the water heater and the second remote control terminal that has been paired with the water heater establish a second communication connection to interact with the second remote control terminal to obtain the network configuration information of the routing device required to access the routing device. The first remote control terminal and the second remote control terminal further exchange information for identity authentication for subsequent pairing verification. The first remote control terminal can access the routing device using the obtained network configuration information of the routing device and perform a second verification to attempt to pair with the water heater connected to the routing device. The remote control terminal does not require the assistance of additional communication equipment in the process of pairing with the water heater, and the user is also exempted from the complicated process of entering the network configuration information of the routing device, which greatly speeds up the pairing speed of the remote control terminal and the water heater and improves the pairing success rate.

[0071] In one embodiment, the second communication connection is a WIFI hotspot connection, see Figure 4 The method for pairing the remote control terminal with the water heater includes steps S402 to S410.

[0072] S402: The first remote control terminal waits for access in AP mode.

[0073] Step S402 is similar to step S202 and can be referred to above.

[0074] S404: After being accessed by the second remote control terminal, the first remote control terminal establishes a second communication connection with the second remote control terminal.

[0075] The second remote control terminal obtains a first signal strength, identifies the target first remote control terminal based on the first signal strength, and then connects to the target first remote control terminal in STA mode. The first signal strength is the signal strength of the first remote control terminal in AP mode. Specifically, the second remote control terminal obtains the strength of the WiFi signal transmitted by the first remote control terminal in AP mode. If the first signal strength meets the communication requirements, the second remote control terminal determines that the first remote control terminal corresponding to the first signal strength is the target first remote control terminal. For example, the communication requirements can be considered met if the first signal strength exceeds a second threshold. It is worth noting that the selection of the first and second thresholds can be determined based on the model and characteristics of the WiFi modules of the second remote control terminal and the water heater. If the WiFi modules of the second remote terminal and the water heater are the same, the first threshold is equal to the second threshold. If the WiFi modules of the second remote terminal and the water heater are different, the corresponding thresholds can also be selected based on the signal strength requirements of their respective WiFi modules. To save energy, the second remote control terminal can obtain the first signal strength at preset intervals. To speed up the communication connection, the second remote terminal can continuously obtain the first signal strength and connect to the target first remote terminal as soon as it is identified. If the second remote control terminal is currently accessing the routing device in STA mode, it should exit the routing device and then access the target first remote control terminal in STA mode. After the second remote control terminal accesses the target first remote control terminal in STA mode, the second remote control terminal establishes a second communication connection with the target first remote control terminal.

[0076] S406, when the first remote control terminal establishes a second communication connection with the second remote control terminal, receives the device information of the second remote control terminal, the network configuration information of the routing device, and the device information of the water heater paired with the second remote control terminal sent by the second remote control terminal, and uses the device information of the water heater paired with the second remote control terminal sent by the second remote control terminal as the main device information.

[0077] Step S406 is the same as step S302 and can be referred to above.

[0078] S408: The first remote control terminal accesses the routing device in STA mode according to the network configuration information of the routing device.

[0079] It can be understood that after establishing the second communication connection with the second remote control terminal and completing the interaction, the first remote control terminal will switch the mode of the WiFi module from AP mode to STA mode and access the routing device in STA mode.

[0080] S410: After accessing the routing device, the first remote control terminal obtains second information and performs a second verification to pair with the water heater.

[0081] Step S410 is the same as step S306 , and reference may be made to the above.

[0082] In one embodiment, there are multiple first remote control terminals waiting for access in AP mode, and the second communication connection is a WIFI hotspot connection. Figure 5 The process of establishing the second communication connection between the second remote control terminal and the first remote control terminal includes steps S502 to S504.

[0083] S502: Each first remote control terminal waits for access in AP mode.

[0084] Step S502 is similar to step S202 and can be referred to above.

[0085] S504: After being accessed by the second remote control terminal, each first remote control terminal establishes a second communication connection with the second remote control terminal.

[0086] The second remote control terminal obtains each first signal strength, determines a target first remote control terminal based on each first signal strength, and sequentially connects to each target first remote control terminal in STA mode in descending order of first signal strength, thereby establishing a second communication connection with each target first remote control terminal. The first signal strength is the signal strength of the first remote control terminal in AP mode. Step S504 is similar to step S404 and may be referred to above. The difference is that in this embodiment, there are multiple target first remote control terminals. The second remote control terminal establishes a second communication connection starting with the target first remote control terminal with the strongest first signal strength. After the second remote terminal completes interaction with the established second communication connection (i.e., receives information sent by the first remote control terminal), it disconnects the current second communication connection and establishes and interacts with the target first remote control terminal with the strongest first signal strength among those with which a second communication connection has not been established. This process is repeated until all target first remote control terminals have established and interacted with the second remote control terminal.

[0087] See also Figure 6 A method for pairing a remote control terminal with a water heater described from the water heater side includes steps S602 to S606.

[0088] S602: When the water heater establishes a first communication connection with the first remote control terminal, the device information of the water heater and the network configuration information of the routing device are sent to the first remote control terminal, and the device information of the first remote control terminal is received from the first remote control terminal.

[0089] The first remote control terminal is the remote control terminal to be paired with the water heater. Step S602 is similar to step S102, and reference may be made to the above.

[0090] S604: The water heater is connected to the routing device in STA mode.

[0091] It can be understood that the water heater accesses the routing device in STA mode after disconnecting the first communication connection with the first remote control terminal.

[0092] S606: After the water heater is connected to the routing device, it obtains third information and performs a third verification to pair with the first remote control terminal.

[0093] Among them, the third information includes the device information of the first remote control terminal connected to the routing device, and the third verification includes determining whether the third information matches the device information of the first remote control terminal sent by the first remote control terminal. It can be understood that the remote control terminal and the water heater need to verify each other, and the pairing is successful after the verifications performed by both parties are passed. Since the first remote control terminal connected to the routing device and the first remote control terminal that has established a first communication connection with the water heater may be different, the water heater needs to perform a first verification. In the case where the routing device is only connected to one first remote control terminal, the first remote control terminal connected to the routing device sends its own device information to the water heater through the transit of the routing device. The water heater verifies whether the device information of the first remote control terminal obtained through the transit of the routing device matches the first remote control terminal sent by the first remote control terminal that has established a first communication connection with the water heater. If they match, the third verification performed by the water heater passes.

[0094] In the case where the routing device is connected to multiple first remote control terminals, each first remote control terminal connected to the routing device sends its own device information to the water heater through the transit of the routing device. The water heater verifies whether there is one of the device information of the multiple first remote control terminals obtained through the transit of the routing device that matches the device information of the first remote control terminal sent by the first remote control terminal. If there is a match, the third verification performed by the water heater passes.

[0095] After being connected to the routing device, the first remote control terminal can also send its own device information to the routing device. The routing device stores the device information of the first remote control terminal. The third information obtained by the water heater can also be read from the routing device.

[0096] Based on the pairing method of the remote control terminal and the water heater in this embodiment, the water heater that has been connected to the routing device establishes a first communication connection with the first remote control terminal to interact with the first remote control terminal and send the first remote control terminal the routing device's network configuration information required to access the routing device. The first remote control terminal and the water heater further exchange information for identity authentication for subsequent pairing verification. After completing the interaction with the first remote control terminal, the water heater connects to the routing device and performs a third verification to attempt to pair with the first remote control terminal connected to the routing device. The remote control terminal does not require the assistance of additional communication equipment in the process of pairing with the water heater, and the user is also spared the complicated process of entering the routing device's network configuration information, which greatly speeds up the pairing speed of the remote control terminal and the water heater and improves the pairing success rate.

[0097] In one embodiment, when the water heater establishes a first communication connection with the first remote control terminal, the water heater also sends its key information to the first remote control terminal. The third information also includes the key information of the first remote control terminal connected to the routing device. The third verification also includes determining whether the key information in the third information matches the key information of the water heater. It will be appreciated that to enhance pairing security, this embodiment incorporates a key mechanism into the pairing process. Each water heater has a corresponding key information, and only the first remote control terminal holding the key information corresponding to the water heater can pair with the water heater. Therefore, during the third verification, the water heater also needs to determine whether the key information sent by the first remote control terminal via the routing device matches the water heater's own key information. The third verification only succeeds if both the key information and the device information in step S606 match. Similarly, after introducing the key mechanism, step S302 or step S406 should be adaptively modified as follows: when the second remote control terminal establishes a second communication connection with the first remote control terminal, the first remote terminal receives, from the second remote terminal, the device information of the second remote terminal, the network configuration information of the routing device, the device information of the water heater paired with the second remote terminal, and the key information of the water heater paired with the second remote terminal.

[0098] See also Figure 7 A method for pairing a remote control terminal with a water heater, described based on the interaction between the water heater and the remote control terminal, includes steps S702 to S710.

[0099] S702: When the water heater establishes a first communication connection with the first remote control terminal, the water heater sends device information of the water heater and network configuration information of the routing device to the first remote control terminal.

[0100] The first remote control terminal is a remote control terminal to be paired with the water heater.

[0101] S704: When the water heater establishes a first communication connection with the first remote control terminal, the first remote control terminal sends the device information of the first remote control terminal to the water heater, and uses the device information sent by the water heater as the main device information.

[0102] For instructions on steps S702 and S704, refer to the instructions on step S102. There is no restriction on the sequence of steps S702 and S704. For example, after the first remote control terminal sends the water heater its device information, the water heater may then send back its device information and the routing device's network configuration information to the first remote control terminal. Alternatively, after the first communication connection is established, both parties may proactively send information.

[0103] S706: The water heater is connected to the routing device in STA mode, obtains the third information, and performs a third verification.

[0104] The third information includes the device information of the remote control terminal connected to the routing device, and the third verification includes determining whether the third information matches the device information sent by the first remote control terminal. For step S706, please refer to the description of step S606.

[0105] S708: The first remote control terminal accesses the routing device in STA mode according to the network configuration information of the routing device, obtains first information, and performs a first verification.

[0106] The first information includes device information of the water heater connected to the routing device, and the first verification includes determining whether the first information matches the main device information. For step S708, please refer to the description of step S106.

[0107] S710: After the first verification and the third verification are both passed, the water heater is paired with the first remote control terminal.

[0108] It is understood that after the water heater is paired with the first remote control terminal, the cloud or routing device can complete the binding between the paired water heater and the first remote control terminal. That is, the routing device or cloud will forward the control instructions issued by the remote control terminal only to the water heater paired with the remote control terminal, and the routing device or cloud will also forward the operating status information feedback from the water heater only to the remote control terminal paired with the water heater.

[0109] Based on the pairing method of the remote control terminal and the water heater in this embodiment, a water heater that has been connected to the routing device establishes a first communication connection with the first remote control terminal to be paired with the water heater, and the water heater interacts with the first remote control terminal. The water heater sends the network configuration information of the routing device required to access the routing device to the first remote control terminal. The first remote control terminal and the water heater further exchange information for identity authentication for subsequent pairing verification. After completing the interaction with the water heater, the first remote control terminal accesses the routing device and performs the first verification. After completing the interaction with the first remote control terminal, the water heater accesses the routing device and performs the third verification. When both the first and third verifications are passed, the pairing of the first remote control terminal and the water heater is completed. The remote control terminal does not require the assistance of additional communication equipment in the process of pairing with the water heater, and the user is also exempted from the complicated process of entering the network configuration information of the routing device, which greatly speeds up the pairing speed of the remote control terminal and the water heater and improves the pairing success rate.

[0110] See also Figure 8 A method for pairing a remote control terminal with a water heater, described based on the interaction between the water heater and the remote control terminal, includes steps S802 to S808.

[0111] S802, when the second remote control terminal establishes a second communication connection with the first remote control terminal, the second remote control terminal sends the device information of the second remote control terminal, the network configuration information of the routing device, and the device information of the water heater paired with the second remote control terminal to the first remote control terminal.

[0112] The first remote control terminal is the remote control terminal to be paired with the water heater, the second remote control terminal is the remote control terminal that has been paired with the water heater, and the water heater is connected to the routing device in STA mode. For step S802, please refer to the description of step S302.

[0113] S804, the first remote control terminal uses the device information of the water heater paired with the second remote control terminal sent by the second remote control terminal as the main device information, and obtains the second information and performs a second verification after accessing the routing device in STA mode according to the network configuration information of the routing device.

[0114] The second information includes device information of the water heater connected to the routing device, and the second verification includes determining whether the second information matches the main device information sent by the second remote control terminal. For step S804, please refer to the description of step S306.

[0115] S806: The water heater obtains fourth information and performs fourth verification.

[0116] The fourth information includes the device information of the second remote control terminal sent by the first remote control terminal connected to the routing device. The fourth verification includes determining whether the fourth information matches the pairing set of the water heater, where the pairing set includes the device information of the second remote control terminal corresponding to the water heater. It can be understood that since the first remote control terminal connected to the routing device is not necessarily a subordinate of the remote control terminal that has been paired with the water heater, the fourth verification is required. In the case where the routing device is only connected to one first remote control terminal, the first remote control terminal connected to the routing device sends its own superior device information to the water heater through the routing device. The water heater determines whether the superior device information of the first remote control terminal matches an item in the pairing set. If there is a match, the fourth verification performed by the water heater passes.

[0117] In the case where the routing device is connected to multiple water heaters, the first remote control terminal of each connected routing device sends its own superior device information to the water heater through the routing device. The water heater verifies whether there is any device information obtained through the routing device that matches the pairing set. If there is a match, the fourth verification performed by the water heater passes.

[0118] S808: After the second verification and the fourth verification are both passed, the water heater is paired with the first remote control terminal.

[0119] It is understood that after the water heater is paired with the first remote control terminal, the water heater will add the device information of the newly paired first remote control terminal to the pairing set, allowing the newly paired first remote control terminal to serve as the second remote control terminal and become the superior of other first remote control terminals. After the water heater is paired with the first remote control terminal, the paired water heater and the first remote control terminal can be bound in the cloud or on a routing device. That is, the routing device or cloud will forward control commands issued by the remote control terminal only to the water heater paired with the remote control terminal, and the routing device or cloud will also forward operating status information feedback from the water heater only to the remote control terminal paired with the water heater.

[0120] Based on the pairing method of the remote control terminal and the water heater in this embodiment, the second remote control terminal that has been paired with the water heater establishes a second communication connection with the first remote control terminal to be paired with the water heater, and the first remote control terminal and the second remote control terminal interact. The second remote control terminal sends the network configuration information of the routing device required to access the routing device to the first remote control terminal. The second remote control terminal and the first remote control terminal further exchange information for identity authentication for subsequent pairing verification. After completing the interaction with the second remote control terminal, the first remote control terminal accesses the routing device and performs the second verification. After completing the interaction with the first remote control terminal, the water heater accesses the routing device and performs the fourth verification. If both the second and fourth verifications are passed, the pairing of the first remote control terminal and the water heater is completed. The remote control terminal does not require the assistance of additional communication equipment in the process of pairing with the water heater, and the user is also exempted from the complicated process of entering the network configuration information of the routing device, which greatly speeds up the pairing speed of the remote control terminal and the water heater and improves the pairing success rate.
