Open box Smart natural gas detector/sensor WiFi CNG

What does "open box" mean?

Open-box products are returned products with opened or damaged packaging, but fully checked from a technical point of view and completely functional. They come with the same warranty as new products.

Shelly Gas CNG is a smart WiFi sensor for detecting combustible gases, certified and calibrated specifically for compressed natural gas (CNG) or LPG, designed to alert occupants to leaks before they become dangerous. It plugs directly into a socket near the risk area (kitchen, boiler, garage with an LPG installation) and does not require an additional hub.

When it detects a gas concentration above the safety threshold (6% LEL), the device triggers an audible alarm of over 70dB, accompanied by a light signal, and instantly sends a push notification to the user's phone through the Shelly Smart Control app. It can also be integrated into automated scenarios, for example automatically closing a gas solenoid valve through another Shelly device.

The housing is flame-resistant and the sensor is certified to the safety standards for gas detectors, giving confidence in its correct long-term operation. It is a small investment in the safety of a home or commercial space where gas appliances are used.

Practical use cases

• Mounted in the kitchen next to the cooker or gas boiler, it detects gas leaks and sends an instant alert to your phone, even when you are not at home.
• It can be connected to a Shelly relay device to automatically close the gas solenoid valve when a leak is detected.
• Recommended for spaces with boilers or gas cylinders, as an additional safety measure alongside smoke sensors.
• It also sounds a local audible alarm, in addition to the app notification, for immediate warning.
