DescribeNew Tuya WIFI Smart Dual Channel Energy Meter with Buzzer Alarm and App Alarm, Setable Threshold 1/2 Clamp 80A - Bidirectional, for measuring exported and imported energy.The App sets the voltage, current, and power thresholds. When the values reach this value, the device buzzes and the App sends an alarm message.Alarm history can be viewed on the AppThe App can clearly display the forward and reverse real-time power, current, and voltage of the A and B channels.Allow calibrationThe device allows calibration so that the value is the same as the billed value2 reverse and forward channels1 channel or 2 channel availableYou can read each channel from the appReverse and forward 2-channel real-time total powerChannel A and B respective power (W)Current(mA)Voltage (V),Power factor and frequency (Hz)Forward and reverse power statistics of each channel.electricity per hour.
