4.1 Adding Authorized Numbers

To receive alerts and control the device, you must add authorized phone numbers. Up to 10 numbers can be authorized; 5 can receive calls/SMS, and 5 can generate alerts for calls/SMS. Use specific SMS commands to add or remove numbers.

4.2 Power Outage Monitoring

The device monitors the external power supply. When AC power status changes (on/off), it sends a text message to the authorized phone numbers. The built-in battery ensures continued operation and alerts during power outages.

4.3 Status Monitoring (Temperature and Voltage)

You can request the current status of the device, including temperature and voltage readings, by sending an SMS command. The device will respond with a short message containing this information. The integrated MCU measures DC voltage from 0 to 36V.

4.4 Scheduled Status Reports

Configure the device to send automatic status reports to authorized numbers at regular, user-defined intervals. This provides proactive monitoring without manual requests.

4.5 Remote Control and Reset

The device can be controlled remotely via SMS commands. This includes the ability to remotely reset the device. It can also reject calls from unauthorized numbers, and users can choose the device's number based on the authorized number list.

6. Troubleshooting

6.1 Device Not Powering On

• Check if the power adapter is correctly connected to the device and a working power outlet.
• Verify the power outlet is supplying power.

6.2 No SMS Alerts or Responses

• SIM Card PIN: Ensure the SIM card's PIN protection is disabled. This is a common issue. Insert the SIM into a mobile phone to disable the PIN.
• SIM Card Validity: Check if the SIM card is active, has sufficient credit (for prepaid), and has SMS services enabled.
• Signal Strength: Ensure the antenna is properly connected and the device is in an area with good GSM signal coverage. Poor signal can prevent SMS transmission/reception.
• Authorized Numbers: Confirm that your phone number is correctly added as an authorized number in the device's configuration.
• SMS Command Format: Double-check the format of your SMS commands. Incorrect syntax will result in no response.

6.3 Incorrect Voltage/Temperature Readings

• Ensure all input connections for voltage and temperature sensors (if external) are secure and correctly wired according to the detailed manual.
• Verify the calibration settings if applicable (refer to the full manual for advanced settings).
