Key features include a large LCD display for local readings, remote control and voice control compatibility via Smart Life/Tuya Smart app, timer and scheduling functions, and energy value storage in case of power loss. The device automatically cuts off power in case of electrical anomalies and attempts to restore power after a set reconnection time.
2. Safety Information
WARNING: Installation and maintenance of this device should only be performed by a qualified electrician. Incorrect installation can lead to electric shock, fire, or damage to the device and connected appliances. Always disconnect power before installation or servicing.
- Ensure the main power supply is disconnected before beginning any installation or wiring.
- Verify voltage and current ratings of the device match your electrical system.
- Do not expose the device to moisture or extreme temperatures.
- Ensure proper grounding as per local electrical codes.
- This device is designed for single-phase AC circuits. Note that for North American 220V systems (two 110V phases), this device may only interrupt one hot phase, leaving the other live. Consult a professional for specific wiring requirements in such configurations.
3. Physical Installation
The SINOTIMER WiFi Smart Energy Meter is designed for DIN rail mounting within an electrical panel or distribution box. Follow these steps for physical installation:
- Power Disconnection: Turn off the main power supply at the circuit breaker or fuse box before starting. Verify power is off using a voltage tester.
- Mounting: Clip the device onto a standard 35mm DIN rail.
- Wiring: Connect the incoming live (L) and neutral (N) wires to the "IN" terminals at the top of the device. Connect the outgoing live (L) and neutral (N) wires to the "OUT" terminals at the bottom. Ensure all connections are secure and tight.
- Verification: Double-check all wiring connections for correctness and security.
- Restore Power: Once installation is complete and verified, restore the main power supply.

4. Setup and Pairing with Smart Life App
To utilize the smart features of your energy meter, you need to pair it with the Smart Life or Tuya Smart application on your smartphone. Ensure your phone is connected to a 2.4 GHz Wi-Fi network, as 5 GHz networks are not supported for initial pairing.
- Download App: Download and install the "Smart Life" or "Tuya Smart" app from your smartphone's app store (Google Play Store for Android, Apple App Store for iOS).
- Register/Login: Open the app and register a new account or log in with an existing one.
- Power On Device: Ensure the energy meter is powered on.
- Enter Pairing Mode: On the energy meter, long press the "WIFI" button (usually indicated by a Wi-Fi icon) for 5 seconds until the Wi-Fi indicator light begins to flash rapidly. This indicates the device is in pairing mode.
- Add Device in App: In the Smart Life app, tap the "+" icon in the top right corner to add a new device. The app should automatically discover the energy meter. If not, manually select "Electrical" > "Smart meter (Wi-Fi)".
- Confirm Indicator: Confirm that the indicator light on the device is flashing rapidly within the app.
- Connect to Wi-Fi: Enter your 2.4 GHz Wi-Fi network password when prompted.
- Pairing Completion: The app will proceed with pairing. Once successful, the device will be added to your app, and the Wi-Fi indicator on the meter will become solid.

5.2. App Remote Control and Monitoring
Once paired, you can control and monitor the device remotely via the Smart Life app:
- Remote ON/OFF: Toggle the power supply to connected devices directly from the app.
- Real-time Monitoring: View current voltage (V), current (A), power (W), and total energy consumption (kWh) in real-time.
- Historical Data: Access historical energy consumption data to track usage patterns.

5.3. Setting Protection Parameters (Alarm Settings)
The app allows you to configure various protection thresholds:
- Leakage Current Alarm: Set the threshold for leakage current (e.g., 10-99mA). If exceeded, the device will trip.
- Over Current Alarm: Define the maximum allowable current (e.g., 1A-63A). The device will trip if this limit is surpassed.
- Overvoltage Alarm: Set the upper voltage limit (e.g., 240V-300V). Power will be cut if voltage goes above this.
- Undervoltage Alarm: Set the lower voltage limit (e.g., 145V-210V). Power will be cut if voltage drops below this.
- Reconnect Time: Configure the delay (e.g., 10s-99s) before the device attempts to re-establish power after a protection trip.
- Reclosing Allowed Times: Set how many times the device can attempt to reclose after a trip. If the issue persists after these attempts, manual intervention is required.
5.4. Timer and Scheduling
Use the Smart Life app to set up schedules and timers for automatic power control:
- Schedules: Create daily or weekly schedules to turn connected appliances ON or OFF at specific times.
- Countdown Timer: Set a countdown timer to automatically turn the power OFF after a specified duration.
6. Maintenance
To ensure optimal performance and longevity of your energy meter:
- Keep the device clean and free from dust. Use a dry, soft cloth for cleaning.
- Do not use abrasive cleaners or solvents.
- Regularly check wiring connections for tightness, especially after initial installation.
- Ensure the installation environment is dry and within the specified operating temperature range.
7. Troubleshooting
If you encounter issues with your SINOTIMER WiFi Smart Energy Meter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not powering on. | No power supply; incorrect wiring. | Check main power supply. Verify wiring connections (IN/OUT, L/N). Consult a qualified electrician. |
| Wi-Fi indicator not flashing during pairing. | Not in pairing mode; device malfunction. | Long press the "WIFI" button for 5 seconds. If still no flash, power cycle the device. |
| Cannot connect to Wi-Fi/App. | Incorrect Wi-Fi band (5GHz); wrong password; weak signal. | Ensure your phone and device are on a 2.4 GHz Wi-Fi network. Re-enter Wi-Fi password carefully. Move device closer to router or improve Wi-Fi signal. |
| Device trips frequently (Overvoltage/Undervoltage/Overcurrent/Leakage). | Protection thresholds set too low; actual electrical anomaly. | Review and adjust alarm settings in the app. Investigate the electrical circuit for actual voltage/current/leakage issues. If leakage protection trips three times, manual reset is required after resolving the underlying issue. |
| Display unreadable or dim. | Viewing angle; backlight issue (for non-backlit models). | Adjust viewing angle. Note that some models (SVP688W) do not have a backlight, while others (SVP688W-L) do. |
| Device does not interrupt both poles in 220V (North American) systems. | Product design for single-phase L-N systems. | This device is designed to interrupt the live (L) line and monitor the neutral (N) line. In North American 220V systems (two 110V hot lines), it may only interrupt one hot line. Consult a qualified electrician to ensure your installation meets local safety codes and requirements for your specific electrical system. |
