Nous E18 Smart Wi-Fi Carbon Monoxide Detector with Audible Alarm and LCD Display

The Nous E18 Smart Wi-Fi Carbon Monoxide Detector with Audible Alarm and LCD Display is a reliable safety device designed to continuously monitor dangerous, odourless, and colourless carbon monoxide gas concentrations in residential and commercial premises. Featuring direct 2.4 GHz Wi-Fi connectivity, this detector operates without the need for an additional hub or gateway, integrating seamlessly with the Nous Smart Home and TUYA ecosystem. When a hazard is identified, the device alerts occupants using a powerful ≥85 dB audible alarm, a flashing light signal, and instant smartphone notifications. An integrated LCD display provides clear, real-time status monitoring directly on the device.

Advantages

This smart carbon monoxide detector offers exceptional protection against invisible and toxic hazards by combining local sirens with remote monitoring capabilities. Its direct Wi-Fi connection eliminates the cost and complexity of extra gateways, while the included battery delivers dependable power for up to 5 years. The combination of an audible siren, visual light indicator, and remote app notifications ensures multiple layers of awareness whether you are at home or away. Furthermore, compliance with the EN 50291-1:2018+AC:2021 standard and a long service life make it a practical, long-term addition to any indoor safety setup.

Suitable for

• Homes and apartments equipped with gas boilers or central heating systems
• Properties featuring indoor fireplaces, wood stoves, or other fuel-burning appliances
• Holiday homes and secondary residences requiring remote smartphone alerts
• Offices and commercial spaces where combustion equipment is present
• Users looking to integrate safety alarms into the TUYA or Nous Smart Home application

When it may not be suitable

This detector is not designed for outdoor use, industrial environments with heavy chemical exposure, or areas where temperatures and humidity regularly exceed the specified operating limits of –10 to +40 °C and under 95% relative humidity. It should also not be relied upon as a primary fire smoke detector, as it is specifically engineered to sense carbon monoxide gas rather than smoke or flames.

How to use

Mount the detector securely on a wall or ceiling in the recommended room location using the provided screws or 3M adhesive material according to the manufacturer guidelines. Connect the device to your local 2.4 GHz Wi-Fi network using the mobile application to enable remote notifications. Perform regular functional tests using the test button located directly on the housing to verify proper operation of the sensor, siren, and display.

What to consider before purchase

• Verify that your premises operate a stable 2.4 GHz Wi-Fi network for app notifications
