NOTE The app can only display the total battery level. Only when you click on the curve can you see the daily and monthly power consumption. The formula for calculating AC power is :P = UI cosθ(cosθ≤1)， cosθ represents the power factor of the circuit. Only resistive loads, such as incandescent lamps, dryers, heaters, electric water heaters, etc., have a power factor equal to 1. When the phase of the live wire of the device is consistent with that of the tested live wire, only the line load will affect the power factor. This device is of the Zigbee version and cannot be directly connected to…
