4. Operating Instructions
Once your TONGOU Smart Energy Monitor is successfully paired with the Tuya/Smart Life app, you can access a range of monitoring and control features.
4.1. Real-time Monitoring
The app provides real-time data on your electrical consumption:
- Real-time Voltage (V)
- Real-time Current (A)
- Real-time Power (W)
- Power Consumption (kWh)
- Internal Temperature (°C/°F)
You can view daily, monthly, and yearly energy consumption statistics and export this data via email for detailed analysis.
4.2. Alarm Settings
Configure various alarm thresholds to receive timely notifications of abnormal conditions:
- Current Setting: Set a maximum current threshold (e.g., 50A).
- Overvoltage Setting: Define the upper voltage limit (e.g., 280V).
- Undervoltage Setting: Define the lower voltage limit (e.g., 100V).
- Overpower Setting: Set a maximum power threshold (e.g., 2000W).
- Temperature Setting: Set a maximum internal temperature (e.g., 100°C).
- Balance Alarm: Set a threshold for energy balance (e.g., 10 kWh).
When any set threshold is exceeded, the app will push notifications to your mobile device, ensuring you are immediately aware of potential issues.
