Measure the amount of precipitation in front of your house with the Netatmo rain gauge: analyse the rainfall in your garden, roof or balcony and calculate how much water your plants still need. The rain gauge measures the precipitation of the last hour and the graphs in the Netatmo app allow you to track the amount of precipitation anywhere and at any time. The Netatmo Rain Gauge works exclusively with the Netatmo Weather Station (sold separately). Maximum one rain gauge per Netatmo Weather Station. (2x AAA batteries, one year lifetime, waterproof).
