Describe 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. 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 App The App can clearly display the forward and reverse real-time power, current, and voltage of the A and B channels. Allow calibration The device allows calibration so that the value is the same as the billed value 2 reverse and forward channels 1 channel or 2 channel available You can read each channel from the app Reverse and forward 2-channel real-time total power Channel 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. (kWh) Daily Electric. (kWh), Electricity per month. (kWh) Electrical of the Year. (kWh) Technical data: Rated voltage: 100-240V AC 50/60Hz Measurable current range: 0.2A-80A WiFi frequency: 2.4GHZ (5Ghz not supported) Ambient temperature range: -10℃～55℃ Power statistics Channel A, B respectively and total daily monthly annual reverse and forward Automation, which allows the creation of scenes for this device together with other graffiti devices 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 Take care to ensure that the circuit being measured is in phase with the module's circuit power supply.
