Low-power smart home device and control method thereof

The invention belongs to the field of Bluetooth communication technology application, and specifically relates to a low-power smart home device and a control method thereof. The main hardware of the system comprises a mobile terminal, display screens, a Bluetooth chip, a processor, a power management circuit, a signal acquisition circuit and a keyboard. A user can communicate with a smart home management box (3) through the Bluetooth of the mobile terminal (1). The home management box is responsible for being networked with a house appliance low-power Bluetooth and intelligently managing house appliances (2) (HA1-HA6). The mobile terminal can manage the house appliances HA in a unified manner by configuring the smart home management box. Networking is realized through Bluetooth time division pairing communication, one processor can manage one or more slave devices, and thus low-power power management can be realized better. The system can achieve the characteristics of low power consumption, low cost, small c
