[Powerful Function & Intelligent Management]: By adopting a high-precise measurement, real-time real-time viewing of voltage, current, and power of each channel when generating and consuming kilowatts via APP to realize intelligent management. It is mainly used in electrical systems, typically used in residential and small commercial settings. [Real-time Management]: The APP displays real-time power, current, voltage, power factor, frequency, and electricity statistics for each channel in forward and reverse directions. With the power statistics function, you can view the daily, monthly, and yearly electricity via the cellphone Tuya APP and keep track of the power consumption at all times. [Automation Function]: With the automation function, you can set the power or current value in the APP. When the power or current exceeds the set value, the device will initiate to work. With a calibration function, the device can be calibrated by adjusting the percentage. [Simple Operation]: 35mm rail mounting, no need to replace wires connection, safer to use, just put the wires in the clip and measure. [Wide Applications]: This can be particularly useful for managing energy consumption and cost, as well as for ensuring the safety and efficiency of the electrical system. Suitable for home appliance management, remote management, housing rental use, industrial control equipment use, intelligent upgrade of power distribution equipment, etc. Name:ZIGBEE Smart Bidirectional Power Monitor Supported APP:Smart Life/Tuya Smart Note:This product needs to be used with zigbee gateways.
