## Summary description

Plug-in QOLTEC 2in1 leak detector that monitors natural gas (CH4/NG) and carbon monoxide (CO). The device provides continuous sensing for gas and CO presence, with compatibility for Tuya smart home integration for remote alerts and control. Suitable for kitchens, boiler rooms and apartments to warn of hazardous gas leaks and prevent poisoning.

## Long description

The QOLTEC 2in1 natural gas (CH4/NG) and carbon monoxide (CO) leak detector is a plug-in sensor designed to monitor the presence of combustible natural gas and toxic carbon monoxide in indoor spaces. The unit continuously senses methane and carbon monoxide levels and provides audible and visual alerts on-site. It also supports Tuya-compatible smart home integration for remote notifications and status monitoring through a connected app or platform.
Advantages
This detector combines dual sensing of CH4 (natural gas) and CO (carbon monoxide) in a single compact plug-in device, reducing the need for separate alarms. Continuous monitoring ensures prompt detection of gas leaks and elevated CO concentrations. Tuya compatibility enables integration with smart home systems for remote alerts, automated responses, and status checks. The plug-in design simplifies installation without the need for hard wiring and allows for easy relocation between rooms.
Suitable for
Kitchens with gas stoves or gas cookers
Boiler rooms and utility spaces with gas-fired equipment
Apartments and living spaces where indoor air safety monitoring is required
Rental properties and multi-room homes requiring portable detection
Key specifications
Sensing gases: methane (CH4/NG) and carbon monoxide (CO)
Form factor: plug-in wall-mounted design for easy installation
Alarm: built-in audible alarm and visual indicator lights
Connectivity: Tuya-compatible smart home integration for remote alerts and control
Power supply: mains powered via standard electrical outlet (plug-in)
Continuous monitoring: real-time detection of gas and CO concentrations
How to use
Plug the detector into a standard electrical outlet in the area you want to monitor, ideally at a level appropriate for the gas type (near the floor for natural gas and at breathing height for carbon monoxide according to local guidelines). Follow the manufacturer’s quick-start instructions to complete initial power-up and calibration if required. Pair the device with a Tuya-compatible app or hub to enable remote notifications and configure alarm settings. Regularly check the device status indicators and test the alarm function according to the provided instructions.
Usage recommendations
Position the detector in locations where gas leaks or CO accumulation are most likely, such as kitchens, adjacent to gas appliances, and in boiler rooms. Avoid placing the unit directly next to heat sources, in damp areas, or behind large furniture that could obstruct airflow. Test the alarm periodically, replace or service the unit according to the manufacturer’s guidance, and ensure Tuya integration is secured with updated app credentials to receive timely remote alerts.
