5. Setup Guide

5.1. Insert SIM Card

Ensure the controller is powered off.
If your Micro SIM card has a PIN code, please disable it using a mobile phone before inserting it into the controller.
Insert the Micro SIM card into the designated slot until you hear a clicking sound.
To remove the SIM card, push it in again until it pops out.

8. User Tips

Always ensure your SIM card has sufficient credit and a stable 4G signal for reliable remote control.
For critical applications, regularly check the device status via the APP or web interface.
When setting up temperature alerts, consider a reasonable hysteresis to prevent frequent ON/OFF cycling.
Keep your device password secure and change it periodically.

9. Troubleshooting

9.1. Network Connection Issues (SIG LED always ON)

If the SIG LED is constantly on, it means the device cannot access the network.

Check SIM Card: Ensure the Micro SIM card is correctly inserted and has no PIN code enabled.
Check Antenna: Verify the 4G antenna is securely connected.
Check SIM Service: Sometimes the problem might be with the SIM card's service itself (e.g., expired plan, no data).
APN Settings: The device needs correct APN (Access Point Name) settings to connect to the network.

APN Configuration:

The default APN is usually 'internet' with empty user/password. If this doesn't work in your country, you need to set the correct APN via SMS.

Check current APN: Send SMS command: SN0000CHECK (replace 0000 with your current password). The device will reply with its current APN settings.
Set APN: Command format: SN+password+APN+length of APN=APN content, length of user=user content, password length =password content.
Example: If APN is datelo.com.br, user algar, password 12345, send: SN0000APN13=datelo.com.br,05=algar,05=12345.
Set APN to null: To set APN, user, and password to null, send: SN0000APN00=00,00=0,00=0.

9.2. SMS Feedback Issues (KT Command)

If you are not receiving feedback SMS in certain situations, you might need to adjust the KT mode.

Activate KT mode: Send SMS command: SN+password+KT+length of country code+S+country code+L+length of number.
Example (France, country code 33, number length 9): SN0000KT2S33L09.
Deactivate KT mode: To close this mode, send: SN0000KTC.
