The Shelly Gas is a compact and highly sensitive Compressed Natural Gas (CNG) detector which provides more protection for your home and family.


  • Standard warranty (included in purchase price): 24-month manufacturer warranty due to device malfunctions when it is used in user manual described conditions.

We mainly think about break-ins and intruders while we're away, yet our homes need to be protected from possible natural disasters too - such as gas leaks. Shelly Gas will notify you immediately when it detects the smallest leak - and together with the add-on, it can turn off the valve to avoid property damage.
