establishing a first connection with the cloud server, and sending the device information of the proxy device to the cloud server through the first connection, so as to establish a second connection between the proxy device and the cloud server based on the first device information and the second device information, the second connection being configured to transmit the keep-alive message; and in response to determining that notification information sent by the cloud server is received, controlling the Internet of Things device to enter a low power consumption mode, the notification information being configured to indicate that the second connection has been established between the proxy device and the cloud server. ## Claims ### Claim 1 A device control method, applied to an Internet of Things device, comprising: sending first device information to a proxy device, the first device information being device information of the Internet of Things device, and the proxy device being configured to act as a proxy for the Internet of Things device to send a keep-alive message to a cloud server; obtaining second device information, the second device information being device information of the proxy device; establishing a first connection with the cloud server, and sending the device information of the proxy device to the cloud server through the first connection, so as to establish a second connection between the proxy device and the cloud server based on the first device information and the second device information, the second connection being configured to transmit the keep-alive message; and in response to determining that notification information sent by the cloud server is received, controlling the Internet of Things device to enter a low power consumption mode, the notification information being configured to indicate that the second connection has been established between the proxy device and the cloud server. ### Claim 2 (depends on 1) The device control method according to claim 1, further comprising: in response to receiving wake-up information sent by the proxy device, controlling the Internet of Things device to enter a working mode. ### Claim 3 (depends on 1) The device control method according to claim 1, further comprising: disconnecting the first connection with the cloud server in response to controlling the Internet of Things device to enter the low power consumption mode, and restoring the first connection and transmitting a service message to the cloud server through the first connection when the Internet of Things device enters a working mode. ### Claim 4 (depends on 2) The device control method according to claim 2, further comprising: disconnecting the first connection with the cloud server in response to controlling the Internet of Things device to enter the low power consumption mode, and restoring the first connection and transmitting a service message to the cloud server through the first connection when the Internet of Things device enters the working mode. ### Claim 5 (depends on 1) The device control method according to claim 1, wherein the notification information comprises local communication key negotiation information of the proxy device and an authentication result of the proxy device by the cloud server. ### Claim 6 (depends on 5) The device control method according to claim 5, further comprising: establishing an encrypted channel with the proxy device based on the local communication key negotiation information of the proxy device, the encrypted channel being configured for information transmission between the Internet of Things device and the proxy device. ### Claim 7 A device control method, applied to a proxy device, and comprising: obtaining first device information sent by an Internet of Things device, the first device information being device information of the Internet of Things device; sending second device information to the Internet of Things device, and the second device information being configured to be sent to a cloud server by the Internet of Things device based on a first connection; establishing a second connection with the cloud server based on the first device information and the second device information; sending a keep-alive message of the Internet of Things device to the cloud server through the second connection when the Internet of Things device enters a low power consumption mode; receiving wake-up information sent by the cloud server, the wake-up information being configured to wake up the Internet of Things device to enter a working mode; and sending the wake-up information to the Internet of Things device, wherein after sending the wake-up information to the Internet of Things device, sending the keep-alive message of the Internet of Things device to the cloud server through the second connection is kept. ### Claim 8 (depends on 7) The device control method according to claim 7, further comprising: sending local communication key negotiation information of the proxy device to the cloud server. ### Claim 9 A device control method, applied to a cloud server, and comprising: establishing a first connection with an Internet of Things device, and obtaining second device information of a proxy device through the first connection; obtaining first device information sent by the proxy device, and establishing a second connection with the proxy device based on the first device information and the second device information; sending notification information to the Internet of Things device, the notification information being configured to indicate that the second connection has been established between the proxy device and the cloud server; receiving a keep-alive message sent by the proxy device through the second connection when the Internet of Things device enters a low power consumption mode; sending wake-up information to the proxy device, the wake-up information being configured to wake up the Internet of Things device to enter a working mode; and continuously receiving the keep-alive message sent by the proxy device through the second connection after sending the wake-up information to the proxy device. ### Claim 10 (depends on 9) The device control method according to claim 9, further comprising: receiving local communication key negotiation information of the proxy device; and sending the local communication key negotiation information of the proxy device to the Internet of Things device. ### Claim 11 (depends on 1) A device control apparatus, comprising: a processor; a communication component; an input/output interface; and a memory configured to store processor-executable instructions; wherein the processor, the communication component, and the input/output interface are configured to execute the device control method according to claim 1. ### Claim 12 (depends on 7) A device control apparatus, comprising: a processor; a communication component; an input/output interface; and a memory configured to store processor-executable instructions; wherein the processor, the communication component, and the input/output interface are configured to execute the device control method according to claim 7. ### Claim 13 (depends on 9) A device control apparatus, comprising: a processor; a communication component; an input/output interface; and a memory configured to store processor-executable instructions; wherein the processor, the communication component, and the input/output interface are configured to execute the device control method according to claim 9. ### Claim 14 (depends on 1) A non-transitory storage medium, storing instructions, wherein the instructions in the non-transitory storage medium cause a terminal to execute the device control method according to claim 1 when executed by a processor of the terminal. ### Claim 15 (depends on 7) A non-transitory storage medium, storing instructions, wherein the instructions in the non-transitory storage medium cause a terminal to execute the device control method according to claim 7 when executed by a processor of the terminal. ### Claim 16 (depends on 9) A non-transitory storage medium, storing instructions, wherein the instructions in the non-transitory storage medium cause a terminal to execute the device control method according to claim 9 when executed by a processor of the terminal.
