Early alerts for natural gas leaks.
GasNet-S4 monitors combustible gas risks for residential indoor use. When connected to WiFi, it can send app alerts to your phone while the built-in alarm alerts people nearby.
Supports app sharing so family members can receive notifications too. Includes a loud local alarm and a plug-in design for quick installation.
Some gas leaks may not be easy to notice by smell alone, especially in enclosed indoor areas. Small leaks can build up quietly, especially in enclosed areas like kitchens, basements, or utility rooms.
GasNet-S4 is designed to monitor natural gas risks in residential indoor spaces and alert you when attention is needed.

Install the device in a suitable position based on the target gas type, room layout, and appliance location. For natural gas monitoring, higher wall placement is commonly used. Always follow the product manual before mounting.
Avoid installing in bathrooms, humid areas, or directly above open flames. Keep away from alcohol, paint, or chemical vapors to reduce false alarms.
For stable app notifications, install the detector within normal home WiFi range and follow the app setup instructions.
Placement should follow the product manual and local safety practices. If you are unsure about the installation location, consult a qualified professional.

Wall-mounted design, USB power, LCD display, and test/mute controls support routine home monitoring.

GasNet-S4 is a WiFi-enabled natural gas alarm designed for residential indoor use. Once powered on and preheated, it continuously monitors the surrounding air for changes in gas concentration.
When the preset alarm threshold is reached, the device triggers a loud on-site alarm and, when connected to WiFi, sends a real-time alert to your smartphone.
After power-on, the detector enters a preheating process before normal monitoring. If the device repeatedly restarts or stays in preheating mode, check the power cable, adapter, and power supply first, then contact support.
GasNet-S4 continuously monitors the surrounding air while powered on. If the detected gas concentration reaches the alarm threshold, the device triggers a local warning and sends an app notification when WiFi is connected.
When a gas warning level is detected, the alarm sounds locally and a notification is sent through the mobile app (WiFi required).
When connected to WiFi, GasNet-S4 works with the Smart Life app to keep you informed of device status and gas alarm notifications.
Connect the detector to a stable 2.4GHz WiFi network.
Enable push notifications in the app.
Use the test function to confirm the alarm and indicators are working.
Share device access with family members if multiple users need notifications.

サポートとドキュメント
Natural gas itself is odorless, but a sulfur-like “rotten egg” smell is added for safety. However, small leaks may not be noticeable by smell alone, especially in enclosed spaces. GasNet-S4 helps monitor combustible gas risks so you are not relying only on smell.
GasNet-S4 is designed to trigger an alarm at 8% LEL, according to the product specification.
Yes. When connected to WiFi, GasNet-S4 sends real-time alerts to your phone through the mobile app. The local audible alarm will still function even if WiFi is temporarily unavailable.
Yes. GasNet-S4 should be used in a dry, protected indoor location within the listed operating range: 32°F–131°F (0°C–55°C). Avoid outdoor, wet, freezing, or exposed areas. Stable USB power supply is also important for normal operation.
No. GasNet-S4 should currently be treated as a natural gas detector. Propane / LPG detection is not confirmed in the current official product documentation, so we do not recommend using it as a propane / LPG detector.
No. GasNet-S4 is designed for natural gas detection. It does not replace a smoke detector, carbon monoxide detector, propane detector, or LPG detector.
If you need smoke and carbon monoxide detection, use a dedicated smoke / CO alarm such asGasNet-CM.
GasNet-S4 requires continuous power via USB to operate. During a power outage, the device will not function unless powered by an external backup source.
Coverage depends on your home layout, gas type, appliance locations, and airflow. Many users place detectors near suitable indoor areas where gas appliances are used. Always follow the product manual for placement guidance.
Once gas concentration drops below the warning level, the detector automatically returns to monitoring mode.
