Smart Wi-Fi Carbon Monoxide (CO) Detector E18, with Audible Alarm, TUYA

Smart Wi-Fi Carbon Monoxide (CO) Detector NOUS E18, with Audible Alarm, TUYA

NOUS E18 is a smart Wi-Fi carbon monoxide (CO) detector designed to continuously monitor dangerous, odourless and colourless CO gas concentrations in residential and commercial premises. When a hazard is detected, the detector alerts you with a ≥85 dB audible alarm, light indication and a phone notification, while the integrated LCD display allows you to monitor the device status.

Carbon monoxide is particularly dangerous because people cannot see, smell or taste it. NOUS E18 is designed for continuous CO monitoring in premises where boilers, fireplaces, stoves or other fuel-burning appliances are used. The local audible alarm serves as the primary warning, while the smart function supplements it with remote notifications on your phone.

The detector connects directly to a 2,4 GHz Wi-Fi network, so no additional ZigBee gateway or hub is required. It is powered by the included CR123A 3 V battery, with a typical operating life of up to 5 years. The manufacturer specifies a 10-year service life for the CO detector itself.

Why Choose This Product?

• Detects an invisible hazard: carbon monoxide is a colourless and odourless toxic gas, so a dedicated CO detector is an important safety device in premises where carbon monoxide may be produced.
• Loud ≥85 dB alarm: when a hazard is detected, the detector emits a powerful audible signal designed to immediately draw the attention of people in the premises.
• Three alert methods: the audible siren is supplemented by a flashing light indicator and an app notification on your phone.
• Remote alerts: when Wi-Fi and internet connectivity are available, the “Nous Smart Home” app can notify you when the CO detector is triggered, even when you are away from home.
• Integrated LCD display: information related to the detector and its status can be viewed directly on the display.
• No smart home gateway required: NOUS E18 connects directly to a 2,4 GHz Wi-Fi network.
• Long battery-powered operation: the CR123A battery has a typical operating life of up to 5 years, so the detector does not require a separate wired power supply.
• 10-year product service life: the manufacturer-specified operating life of the CO detector makes it easier to plan its replacement.

Who Is This Product For?

The NOUS E18 smart CO detector is intended for premises where carbon monoxide may be produced due to heating, hot water production or other combustion processes.

• Homes and apartments with gas boilers where continuous CO monitoring is required.
• Homes with fireplaces or stoves where improper combustion or problems with exhaust gas removal may create a carbon monoxide hazard.
• Holiday homes and less frequently occupied properties where supplementing the local alarm with remote phone notifications can be useful.
• Offices and commercial premises where there may be a risk of CO formation depending on the type of equipment used.
• TUYA and NOUS smart home users who want to monitor the status of a safety detector in a smart home app.

Practical Applications at Home and in Heated Premises

• Use the CO detector in premises with a gas boiler or other fuel-burning heating appliance in accordance with the manufacturer's installation instructions.
• Install the detector in homes where a fireplace or stove is used to monitor potential carbon monoxide hazards.
• In a holiday home or another less frequently occupied property, use the Wi-Fi function to receive additional alerts on your phone.
• Regularly test the detector using the button on the device in accordance with the manufacturer's instructions.
• Replace the entire device with a new one after the manufacturer-specified 10-year detector service life has expired.

Protection Against a Hazard That Cannot Be Seen or Smelled

Carbon monoxide is often called the “silent killer” because it is colourless, odourless and cannot be detected by human senses. Therefore, a dedicated CO alarm is required to warn of dangerous concentrations in a room. NOUS E18 continuously performs this task and activates a local audible and visual alarm in the event of danger.

The Wi-Fi function provides an additional layer of safety – a notification can be received in the “Nous Smart Home” app when the detector is triggered. However, the remote notification is an additional feature and does not replace the local audible alarm. If the CO alarm is activated, you should immediately follow the actions specified in the detector instructions and the recommendations of local safety authorities.

Technical Specifications

Frequently Asked Questions (FAQ)

What is carbon monoxide and why is a CO detector required?
Carbon monoxide (CO) is a toxic, colourless and odourless gas that cannot be detected by human senses. A CO detector monitors its concentration and activates an audible alarm in the event of a dangerous situation.

How does NOUS E18 alert you to carbon monoxide?
The detector uses three alert methods: a ≥85 dB audible alarm, a flashing light signal and a notification in the “Nous Smart Home” app.

Does NOUS E18 require a ZigBee gateway?
No. The detector connects directly to a 2,4 GHz Wi-Fi network, so no additional ZigBee gateway or smart home hub is required.

Will the CO detector work if the internet connection is lost?
Local carbon monoxide detection and the audible and visual alarms are not designed to depend on the remote app connection. However, a working Wi-Fi and internet connection is required for phone notifications.

How long does the NOUS E18 battery last?
The manufacturer specifies a typical CR123A battery life of up to 5 years. Actual battery life may depend on Wi-Fi connection quality, the number of alarm activations and operating conditions.

Where should the carbon monoxide detector be installed?
The installation location of a CO detector depends on the room and potential sources of carbon monoxide, so the NOUS E18 user instructions and applicable safety country requirements must be followed. The detector should not be installed simply based on convenience, as an unsuitable location may reduce the effectiveness of the warning.

Choose the NOUS E18 smart Wi-Fi carbon monoxide detector if you want to monitor CO hazards not only with a local ≥85 dB audible alarm but also with smart notifications on your phone. The integrated LCD display, direct 2,4 GHz Wi-Fi connectivity, battery life of up to 5 years and compliance with EN 50291-1:2018+AC:2021 provide a practical solution for indoor CO monitoring.
