Let it Rain
If you like Netatmo’s minimalist weather station, you’ll love the device’s add-on rain gauge. The small unobtrusive device costs $79 and immediately lets you know that it’s started to rain. Like the temperature and humidity gauge, it connects to the base station wirelessly. Inside is a tipping bucket that empties itself every 24 hours so that you get accurate daily rain-level readings. The device requires a pair of AAA batteries and is accurate to within 1 millimeter an hour.
