The Tuya Smart WiFi Combustible Gas Detector is designed to detect combustible gas leaks in indoor areas such as kitchens. Available documentation identifies support for natural gas (methane/CH4) and LPG, with the detector monitoring gas concentration and triggering an audible alarm when the specified threshold is reached.
The detector connects to a 2.4GHz Wi-Fi network and works with the Tuya Smart or Smart Life app. The app can provide gas-leak notifications and display the detected gas concentration, while the built-in alarm provides a local warning even when the Wi-Fi connection is unavailable.
The available manual specifies a 70dB alarm, a 6%LEL ±3%LEL methane alarm threshold, and an operating temperature range of -10°C to +50°C. The documentation also specifies AC 85–250V power for this version, so I have not added battery-related specifications.
