Describe<br> New 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.<br> 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.<br> Alarm history can be viewed on the App<br> The App can clearly display the forward and reverse real-time power, current, and voltage of the A and B channels.<br> Allow calibration<br> The device allows calibration so that the value is the same as the billed value<br> 2 reverse and forward channels<br> 1 channel or 2 channel available<br> You can read each channel from the app<br> Reverse and forward 2-channel real-time total power<br> Channel A and B respective power (W)<br> Current(mA)<br> Voltage (V),<br> Power factor and frequency (Hz)<br> Forward and reverse power statistics of each channel.<br> electricity per hour. (kWh)<br> Daily Electric. (kWh),<br> Electricity per month. (kWh)<br> Electrical of the Year. (kWh)<br> Technical data:<br> Rated voltage: 100-240V AC 50/60Hz<br> Measurable current range: 0.2A-80A<br> WiFi frequency: 2.4GHZ (5Ghz not supported)<br> Ambient temperature range: -10℃～55℃<br> Power statistics Channel A, B respectively and total daily monthly annual reverse and forward<br> Automation, which allows the creation of scenes for this device together with other graffiti devices<br> For example, when reverse or forward power (watts) or kilowatt hours reaches a certain value, another graffiti switch can be turned on, or turned off Wiring diagram<br> Take care to ensure that the circuit being measured is in phase with the module's circuit power supply.<br> Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Minnanxin
