Many gas leaks don’t produce a strong odor at first. Small leaks can build up quietly, especially in enclosed areas like kitchens, basements, or utility rooms.
GasNet-S4 is designed to monitor for residential natural gas leaks and alert you early, helping you respond before a situation escalates.

From kitchen stovetops to basement water heaters, gas leaks can occur in everyday residential settings. GasNet-S4 is designed to monitor natural gas in common household environments and alert you when attention is needed.
When WiFi is connected, alerts are sent directly to your phone, helping you stay informed whether you’re home or away.






Designed to respond quickly to changes in natural gas concentration, supporting timely awareness in residential spaces.
Combines a loud on-device alarm with mobile app notifications, so you can react promptly when a warning is triggered.


When connected to WiFi, GasNet-S4 allows you to check device status and receive alerts remotely through the Smart Life app.
Simple controls, clear indicators, and a bright LCD screen make everyday monitoring easy for the whole household.

GasNet-S4 is a WiFi-enabled natural gas alarm designed for residential use. Once powered on and preheated, it continuously monitors the surrounding air for changes in natural gas concentration.
When the preset safety threshold is reached, the device immediately triggers a loud on-site alarm and, when connected to WiFi, sends a real-time alert to your smartphone — helping you respond quickly, even when you’re away from home.
The point of using dummy text for your paragraph is that it has a more-or-less normal distribution of letters. making it look like readable English.
When a gas warning level is detected, the alarm sounds locally and a notification is sent through the mobile app (WiFi required).
Installation Steps .

Mount the detector on an upright wall near gas appliances such as stoves or water heaters.
Install the device approximately 2 meters above the gas source, where natural gas is more likely to accumulate.
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.
When connected to WiFi, GasNet-S4 works with the mobile app to keep you informed of device status and gas alerts in real time. This added visibility helps you stay aware of potential issues, whether you’re at home or away.

External smart gas valve control requires compatible devices and separate configuration.
Support and Documentation
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 for early warning signs beyond human senses.
GasNet-S4 is designed to trigger an alarm when gas concentration reaches 8% LEL, a commonly used residential safety threshold.
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.
GasNet-S4 is designed for residential natural gas detection.
Gas detection compatibility depends on gas type and sensor configuration. For other gases such as propane (LPG), suitability may vary by installation environment and system setup.
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’s size and layout. For most homes, installing at least one detector per floor or near major gas appliances is recommended.
Once gas concentration drops below the warning level, the detector automatically returns to monitoring mode.
Use the TEST button on the device to perform a function check or follow the user manual for reset instructions.
