A healthier home

We spend 80% of our time indoors – yet indoor air is often more polluted than outside. The Netatmo Weather Station measures indoor pollution through a CO2 sensor, sending you alerts so you can air out your home when necessary… and live in a healthier environment.


Connect up to three Indoor Modules and monitor all your rooms and measurements with a single application.

Family room

Have trouble relaxing in your living room? It may be due to the indoor air quality. Receive an alert if the CO2 level rises sharply.

View your data history to understand changes in the room over time

View changes in your environment at a glance using charts accessible in the app. Humidity problems in the bathroom? Monitor how that evolves over time.

Customize your notifications to choose which alerts you receive

Receive the information that matters most to you - such as excessively high CO2 levels or a drop in temperature - directly on your smartphone.

Long battery life

Energy-efficient, up to 1 year of battery life.


Put it wherever you like in the room you want to monitor; there's no need to plug it in!

In all your bedrooms

Monitor up to 3 rooms at the same time.

Connect with other devices in your smart home

Netatmo lets you use the data from your Additional Module to communicate with other devices in your home. For example, you can use the IFTTT app to activate the fan when the temperature in the room with the additional module exceeds 30°C.

Partner applications: IFTTT, Weatherpro, Imperihome, Instaweather Pro.
