4. Setup Guide

4.1. Device Layout and Indicators

SIG Indicator: One flash per second means entering the GSM network. One flash in two seconds means entering the 4G network. APP control is allowed only when connected to 4G network.

SET Button: Short press to set the master number. Long press for 8 seconds to reset the system (SIG will flash 5 times if reset is successful).

4.2. Insert SIM Card

Before powering on the device, insert a valid 4G SIM card into the SIM card slot. Ensure the SIM card does not have a PIN code enabled; if it does, please disable it using a mobile phone before insertion.

4.3. Connect to 4G Network

After inserting the SIM card and powering on the controller, the SIG LED will flash. When the SIG LED flashes every 2 seconds, it indicates a successful connection to the 4G network. If the SIG LED remains constantly on, it means there is no network access. In this case, check the SIM card installation, antenna connection, or contact your SIM service provider.

4.4. Set Device Password

The factory default password is 0000. You can change it via SMS. Passwords must consist of 0-9 Arabic numerals (no letters or symbols).

SMS Command Format: SN+password(4 numbers)+NEW+new password

Example: To change the password from 0000 to 1234, send the SMS: SN0000NEW1234. You will receive a confirmation SMS: NEW SN SETOK NEW SN IS 1234 (New password).

4.5. APN Setup (for Network Mode)

APN (Access Point Name) settings are crucial for the controller to access the 4G data network. The APN must be correctly configured for your country's network provider.

Factory Default APN: The default APN is internet with an empty username and password (APN:internet user: password:).

Check Current APN: Send SMS command: CHECK. You will receive: APN:internet user: pass:.

Set Custom APN:

SMS Command Format: SN+password+APN+length of APN+APN content,length of user+user content,length password =password content

Example 1 (with user/password): For APN: datelo.com.br, user: algar, password: 12345, send: SN0000APN13=datelo.com.br05=algar,05=12345. You will receive: APN:datelo.com.br user:algar pass:12345.

Example 2 (empty user/password): For APN: cmnet, user: (empty), password: (empty), send: SN0000APN05=cmnet,00=,00=0. You will receive: APN:cmnet user: pass:.

6. Maintenance

• Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
• Connections: Periodically check all wiring connections (power, relays, sensors, antenna) to ensure they are secure and free from corrosion.
• SIM Card: Ensure the SIM card is active and has sufficient credit/data plan for continuous operation, especially for SMS and 4G data functions.
• Firmware Updates: Check the manufacturer's website or APP for any available firmware updates to ensure optimal performance and security.
• Environmental Conditions: Operate the device within its specified temperature and humidity ranges to prevent damage.

7. Troubleshooting

• No Network Access (SIG LED always on):
  - Check if the SIM card is correctly inserted.
  - Ensure the 4G antenna is securely connected.
  - Verify that the SIM card is active and has a valid data plan/credit.
  - Confirm that the APN settings are correct for your network provider (refer to Section 4.5).
• SMS Commands Not Working:
  - Double-check the SMS command format and ensure the password is correct.
  - Verify that the SIM card has sufficient credit to send SMS messages.
  - Ensure the master numbers are correctly set if using specific features.
• APP Not Connecting/Controlling:
  - Confirm the device has a stable 4G network connection (SIG LED flashing every 2 seconds).
  - Check your phone's internet connection.
  - Ensure the APN settings on the controller are correct.
  - Verify that the device is added correctly in the WLTE Control APP.
• Relays Not Responding:
  - Check the power supply to the controller.
  - Inspect the wiring to the relays and the connected equipment.
  - Ensure the control commands (SMS, APP, Web) are being sent correctly and acknowledged by the controller.
• Temperature/Humidity Control Issues:
  - Ensure the external sensor is correctly connected to the sensor interface.
  - Verify that the temperature/humidity thresholds and control logic are correctly configured in the APP or via SMS commands.

8. User Tips

• SMS Command Clarity: When using SMS commands for ON/OFF or other functions, always double-check the exact syntax, including the password and any specific channel numbers or parameters. A common user query relates to the 'sending formula for locking and unlocking', which refers to the precise SMS commands for controlling relays.
• APN Configuration: For reliable 4G data network control via the APP or web, ensure your APN settings are accurately configured for your local mobile network provider. Incorrect APN settings are a frequent cause of connectivity issues.
• Sensor Integration: If utilizing temperature and humidity control, remember that the sensors are typically purchased separately. Ensure they are compatible and correctly wired for accurate readings and automated actions.
• Security: Change the default password immediately after initial setup to prevent unauthorized access.
