Temperature measurement

The temperature is measured by both indoor and outdoor modules.

Minimum and maximum

Click on the temperature and then on the settings button to choose whether or not to display the minimum and maximum temperatures on your dashboard.

Minimum and maximum temperatures are the highest and lowest temperatures measured during 24 hours, from midnight to midnight.

Temperature trend

The little arrow appears next to the temperature to shows whether it's increasing or decreasing. The trend is calculated over the last hour.

“Feels like” temperature

Your Netatmo Dashboard displays a “feels like” temperature. This is computed data, obtained by adding the combined effect of moisture and wind over human perception of heat and cold. To achieve reliable data, the station uses a combination of two usual formulae: wind-chill which represents the effect of wind on cold temperatures and Humidex/Heat Index which represents the effect of moisture on high temperatures.

Humidex vs. Heat index setting

The formula used to represent the effect of moisture on high "feels like" temperature is either Humidex or Heat index, depending on your geographical region. Default settings use Heat index in the United States, and Humidex in Canada and Europe. You can manually change the formula used in the My Account > Profile > Units section.

Dew point

It is the temperature to which air must be cooled to reach saturation (assuming air pressure and moisture content are constant). When saturation is reached, water vapour starts condensing into liquid water. A higher dew point indicates more moisture present in the air. The dew point is always lower than (or equal to) the air temperature.

Did you know?

The indoor comfort temperature ranges from 19°C to 24°C (66.2°F to 75.2°F) in Winter time, and 23°C to 26°C (73.4°F to 78.8°F) in Summer time. Comfort temperature depends on the humidity level: the dryer the air, the higher the comfort temperature.

Wise steps for accurate temperature measurements

You will improve the accuracy of your temperature measurements by protecting your modules from exposure to direct sunlight. Also, measurements on demand, when used frequently, trigger the indoor module's lights, which may artificially increase the measured temperature.
