7. Troubleshooting
This section addresses common issues you might encounter with your PGST alarm system.
| Issue | Possible Cause | Solution |
|---|---|---|
| System not connecting to WiFi | Incorrect WiFi band (5GHz), wrong password, weak signal. | Ensure your router is broadcasting a 2.4GHz network. Double-check the WiFi password. Move the panel closer to the router or use a WiFi extender. |
| Sensors not triggering alarm | Low battery, improper installation, sensor out of range. | Check sensor batteries and replace if needed. Verify sensor alignment (door/window) or clear line of sight (motion). Ensure sensors are within the main panel's wireless range. |
| No app notifications | App permissions not granted, phone's notification settings, app not running in background. | Check your phone's app settings to ensure notifications are enabled for Tuya Smart/Smart Life. Ensure the app is allowed to run in the background. |
| False alarms | Improper sensor placement, pets, environmental factors. | Adjust motion sensor sensitivity or reposition to avoid pets. Ensure door/window sensors are securely mounted and not affected by drafts. |
| Anti-demolition alarm triggered | Main panel moved or tampered with. | This is a security feature. If the main panel is detached from its mounting, it will trigger an alarm and send a notification. Re-secure the panel properly. |
