Accurately assess your environment with the Smart Home Weather Station

Analyse your indoor and outdoor environments in real-time

The Smart Home Weather Station lets you analyse your environment straight from your smartphone, giving an instant overview of your environment.
Your Weather Station measures indoor and outdoor temperature, noise levels, indoor air quality as well as air pressure with incomparable precision. The information for weather forecasts and outdoor air quality is provided by specialised organisations. The weather and humidity data lets you organise your outdoor activities better, while the indoor temperature and air quality readings help you make your home more comfortable.

Set customised alerts

You can set up the app to receive customised notifications about changes in your environment.
Is the temperature below freezing? The Smart Home Weather Station can instantly send a notification to your smartphone so that you can bring your plants inside.

More than just weather readings: improve your indoor air quality

A home’s indoor air can be up to five times more polluted than the outdoor atmosphere. To make your environment cleaner, the Smart Home Weather Station tells you the CO₂ levels of a room using a coloured halo, and alerts you in real-time on your smartphone as soon as the quality of your air deteriorates: it's time to open the windows!

Access your Weather Station’s readings from anywhere

With the Netatmo app, you can check your Smart Home Weather Station readings, even when you’re far from home. You can also view previous readings to help you understand how your environment has changed over time.
