Troubleshooting

Common Issues and Solutions

Problem	Possible Cause	Solution
System does not connect to WiFi.	Incorrect WiFi password, 5GHz network, special characters in password, router compatibility.	Ensure your WiFi network is 2.4GHz. Verify the WiFi password is correct and contains no special characters. Restart your router and the alarm panel. Check router settings for compatibility.
No app notifications or status updates.	App permissions, background data restrictions, network issues, app limitations.	Check your phone's app permissions for "Tuya Smart" (notifications, background data). Ensure your phone has a stable internet connection. Rely on SMS/call alerts as a primary notification method if app notifications are inconsistent.
SIM card not recognized or SMS/call functions not working.	SIM PIN active, incorrect SIM card size, poor signal.	Deactivate the SIM card's PIN code using a mobile phone before inserting it into the alarm panel. Ensure the SIM card is a standard size (25mm x 12mm) and inserted correctly. Check for GSM signal strength on the panel.
Cannot set entry/exit delay times on the keypad.	Specific model limitation or menu navigation issue.	Some settings might be exclusively configurable via the mobile app. Refer to the detailed menu guide within the panel's interface or the app for delay settings.
False alarms from PIR sensors.	Improper placement, pets, drafts, direct sunlight.	Ensure PIR sensors are not facing windows, heat sources, or areas with strong air currents. Consider using 'Intelligent Zone' for areas with pets. Adjust sensor sensitivity if available.
