Tuya series products do not suitable for all compatible with Samsung devices. _x005f_x000D_ 2. Bluetooth-compatible is only used for network signal connection and cannot be used alone. WiFi+Bluetooth-compatible is more stable. _x005f_x000D_ 3. This product is used to detect biogas, natural gas, and methane. Unable to detect smoke. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1 x Gas Leak Sensor  _x005f_x000D_ 1 x USB cable  _x005f_x000D_ 2 x Screw  _x005f_x000D_ 1 x Instructions 1. Wifi+Bluetooth-compatible Dual Mode: Faster connection to the network. Connecting to the network is three times faster than WiFi single mode, and WiFi+Bluetooth-compatible dual mode of gas leak sensor is more stable and faster. 2. Large Screen LCD: Real-time display of gas concentration and equipment status to understand leakage. Automatically detects faults, and the yellow light comes on when there is a fault. 3. Sound & Light & APP Remote Alarm: 90DB sound alarm and red light alarm to remind the gas concentration to reach the alarm value. When the gas concentration reaches the alarm value or above, the gas leak detector will send an audible and visual alarm signal and push it to the APP. 4. Detect Temperature Change: If the set temperature value is exceeded, the home gas alarm will send an alarm. When the smart WiFi gas leak detector is offline, the app will remind the device to be offline after 30 minutes. 5. USB Power Supply: USB charging does not require the purchase of a battery, and data can be updated in real time, making data more accurate. Supports detection of natural gas, biogas, and methane. Note that smoke detection is not supported.
