Frequently Asked Questions

Is there an alarm to detect gas?

For full safety coverage, yes. Gas detectors catch invisible gas leaks early, while smoke and carbon monoxide detectors handle fire and CO threats. Using both together gives you peace of mind around the clock.

Do natural gas detectors really work?

Absolutely. Our WiFi gas detector connects to your home network and sends real-time alerts to your phone via the Tuya Smart App—no hub required.

How does a gas detector alert you?

Our device detects multiple gases, including natural gas (methane) and propane. It's ideal for kitchens, basements, RVs, and more.

What type of gases can the Gas Leak Detector identify?

Install it near gas appliances (like stoves or water heaters) and at ceiling level, since natural gas rises. Avoid corners or behind furniture.

Will the Gas Leak Detector still function during power outages?

Yes, the gas detector comes with a built-in, rechargeable battery that ensures continuous functionality, even during a power outage.

What's the range of the Gas Leak Detector? How many do I need for my house?

The range depends on the size and layout of your home. We recommend at least one detector per floor for optimal coverage.

How quickly does the Gas Leak Detector reset after an alarm?

The detector is designed to reset automatically once the gas concentration drops below the predefined safety levels. The time it takes can vary depending on how quickly the gas dissipates.

How do I reset the device?

Press and hold the reset button for 5 seconds until the device restarts.

What should I do if the device doesn't alarm?

Refer to the user manual for detailed steps on battery replacement.
