Your Alarm continuously measures carbon monoxide levels, an odourless gas that can be deadly. It warns you in real-time if the risk threshold is crossed. It alerts those present with its 85-decibel alarm and simultaneously warns you on your smartphone so that you can immediately warn your family and the emergency services.

The Carbon Monoxide Alarm comes with a battery that lasts 10 years*, which is the maximum lifespan of any CO detector.

That means you don’t need to change any batteries because when you receive a low-battery alert, you’ll know it’s time to replace your Alarm.

With the auto-test feature, your Alarm checks the status of its battery, sensor, and Wi-Fi connection, sending you a notification in case of any issues.

The Carbon Monoxide Alarm is a standalone product and works without any additional equipment. It offers the best protection for you and your family, subscription-free.

Your Smart Alarm is battery-powered and easy to install. Place one in each room where there is a fuel-burning appliance (boiler, fireplace, gas cooker, etc.).

Create an ecosystem tailored to your needs. Access all your Netatmo security products and their features in the Home + Security app, with no subscription fees or any extra costs.

Do you have a Netatmo Smart Thermostat for your gas, oil or wood boiler? With Apple HomeKit compatibility, you can create a scene so that your Netatmo Thermostat shuts off the boiler whenever the alarm detects carbon monoxide.
