The Protector Socket features a clear digital display that provides real-time information about your power usage and status. Refer to Figure 4.1 for a detailed description of each displayed value.
Figure 4.1: Digital display explanation. Values include Voltage (V), Current (A), Leakage (mA), Kilowatt (kW), Kilowatt-hour (kWh), Frequency (Fr), Power factor (cos), and Prepaid power value (n kWh).
4.2 Setting Protection Values via Tuya APP
The protective thresholds for overvoltage, undervoltage, overcurrent, and leakage can be customized through the Tuya Smart app to suit your specific needs and local conditions.
- Open the Tuya Smart app and select your Protector Socket device.
- Navigate to the settings or protection parameters section within the device interface.
- Adjust the following values as required:
- Overvoltage Protecting Value: Set the maximum voltage threshold (e.g., 230-300V).
- Undervoltage Protecting Value: Set the minimum voltage threshold (e.g., 140-210V).
- Over-current Protecting Value: Set the maximum current threshold (e.g., 1-16A).
- Leakage Protecting Value: Set the maximum leakage current threshold (e.g., 10-99mA).
- Recovery Delay Time: Configure the delay before power is restored after a fault (e.g., 1s-500s).
- Power-on Display Internal Delay Time: Set the delay for the display to show values after power-on (e.g., 1s-500s).
- Over-voltage Recovery Value: Set the voltage at which the device will recover after an overvoltage event.
- Under-voltage Recovery Value: Set the voltage at which the device will recover after an undervoltage event.
- Over Current Recovery Value: Set the current at which the device will recover after an overcurrent event.
- Action Time: Set the response time for protection actions (e.g., 0.1-30s).
- Continuous Faults Times: Configure how many continuous overcurrent/leakage faults are allowed before permanent lockout (default OFF).
- Save your settings. The changes will be applied to the socket.
4.3 Automatic Protection and Recovery
The socket is designed to automatically detect and respond to power anomalies:
- If an over-voltage, under-voltage, over-current, or leakage fault occurs, the device will instantly disconnect power to the connected appliance.
- Once the voltage or current returns to within the safe, configured range, the device will automatically restore power after the set recovery delay time.
- This automatic reset feature prevents prolonged power outages to your appliance while ensuring protection.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Socket not powering on/display off | No power from wall outlet; device malfunction. | Verify the wall outlet is functional by plugging in another device. Ensure the Protector Socket is fully and securely inserted into the outlet. If the issue persists, contact customer support. |
| Appliance connected to socket has no power | A protection mechanism has been triggered (overvoltage, undervoltage, overcurrent, or leakage); appliance fault. | Check the socket's digital display for any fault indicators (e.g., high/low voltage, high current, leakage). The device should automatically recover after the set delay once conditions normalize. If the issue persists, check the connected appliance for faults or review and adjust protection settings in the Tuya app if thresholds are too sensitive for your appliance. |
| WiFi connection issues | Incorrect WiFi password; attempting to connect to a 5GHz network; router too far; pairing mode not activated correctly. | Ensure your smartphone is connected to a 2.4GHz WiFi network and that you are entering the correct password. Move the socket closer to your WiFi router. Re-initiate the pairing mode process as described in the setup instructions. |
| Inaccurate voltage/current readings on display or app | Minor calibration discrepancy. | Utilize the manual calibration function available in the Tuya app settings to fine-tune the voltage, current, or kilowatt readings within the -20% to +20% range. |
