[High-Performance Features and Intelligent Management]: Thanks to high-precision measurement, view the voltage, current, and power of each channel in real time during energy production and consumption (in kilowatts) via the app for intelligent management. This system is primarily used in electrical installations, particularly residential and small commercial. [Real-Time Management]: The app displays real-time power, current, voltage, power factor, frequency, and power consumption statistics for each channel, in forward and reverse operation. The consumption statistics function allows you to view and continuously monitor your daily, monthly, and annual power consumption via the Tuya mobile app. [Automation Function]: The automation function allows you to set power or current values in the app. When the power or current exceeds these values, the device switches on. The calibration function allows the device to be calibrated by adjusting the percentage. [Easy to Use]: Mounts on a 35 mm rail; no need to replace wire connections, safer to use—simply place the wires in the clip and measure. [Numerous Applications]: This device can be particularly useful for managing energy consumption and costs, as well as ensuring the safety and efficiency of the electrical system. Suitable for managing household appliances, remote management, rental properties, industrial control equipment, smart upgrades of power distribution equipment, etc. Name: Zigbee Smart Bidirectional Power Monitor Compatible Applications: Smart Life/Tuya Smart Note: This product requires a Zigbee gateway.
