The low-power device 10 and the keep-alive server 20 establish a keep-alive link through a network transmission protocol.

It can be understood that the external event triggering generally includes the occurrence of a sudden event. For example, when the low power consumption device 10 is an intelligent low power doorbell, the external event triggering may be a doorbell pressing, and the low power consumption device 10 is a smart low. For power-consuming cameras, the external event trigger can be triggered by a human body infrared sensor (PIR).

2. The micro processing unit MCU powers up the main control unit;

3. The master starts to restore the low-power Wi-Fi from the low-power mode to the normal working mode;

4. After the main control initializes the network protocol stack, it connects to the push server, performs authentication processing, and obtains push authorization;

5. The master pushes the message to the push server;

6. The push server will push the message to the client;

7 The client receives the push message.
