Feature:1. Powerful Function: High-precise measurement, real-time monitoring of voltage, current and power of each channel when generating and consuming kilowatts.2. Mobilephone APP Control: The app displays real-time power, current, voltage, power factor and frequency of channel for forward and reverse.3. Power Statistics: APP program displays daily, monthly and yearly reverse and forward totals of channel individually. Power usage percentage display to avoids abnormal power usage.4. Automation Function: You can set the power or current value in APP, only when the power or current exceeds the value, the device will starts to work.5. Feature-rich Design: Automated setting of valve-values and push notifications, and the device is able to be calibrated by adjusting the percentage.6. Easy Installation: 35mm rail mounting, no need to replace wires connection is safer, just put the wires in the clip and measure.7. Note: ZigBee products need to be used with gateways.Specification:This Tuya ZigBee intelligent energy meter helps measure how much energy the solar and photovoltaic system is producing and how much power it is consuming by monitoring application. Controlled by the Tuya APP, the app displays real-time power, current, voltage, power factor and frequency for channel for forward and reverse. Supports automatic setting of valve-values and with push notifications, and the device can be calibrated by adjusting the percentage.Features:Powerful Function: High-precise measurement, real-time monitoring of voltage, current and power of each channel when generating and consuming kilowatts.Mobilephone APP Control: The app displays real-time power, current, voltage, power factor and frequency of channel for forward and reverse.Power Statistics: APP program displays daily, monthly and yearly reverse and forward totals of channel individually.
