Features: [Automatic Reclosing]: Intelligently identify the leakage and when it occurs overvoltage and under voltage, the protector will automatically cutoff the powersupply, if the fault has been eliminated, it will automatically reclose and turn on the power. [Mobilephone APP Control]: After downloading the mobilephone Tuya/SmartLife APPyou can remotely control and view the power on/off switching status of the device whenever and wherever you want via the mobilephone APP. Whether you are on vacation, at work or home, you can enjoy the convenience of the mobilephone APP. [APP Data Viewing & Electricity Metering]: Support to view the current, power, voltage, leakage current, temperature, number of faults, total battery capacity, and recharge capacity on your cellphone. Record(year, month, day, hour) electricity consumption in different time periods. [Photovoltaic Bidirectional Metering]: View the electricity input from photovoltaic power generations, and the APP can view the electricity generating input at the time, day, month, and year. With prepaid function. [Timing Schedule]: Three timing modes of timing mode, countdown mode, loop timing design can meet the needs of users in different scenarios, help users better manage time and improve the efficiency of life and work. Note: ZigBee version needs to be used with the gateways.
