Yes, I am aware of the calibration process and have been submitting reports for six weeks or so… However, I have yet to see any improvement in its rain reporting to date… It is best with light rain and increasing inaccurate as the rain intensity increase… It is also interesting how heavy thunder can produce false rain readings. Source: The sample for this review was provided by WeatherFlow. I’ve enjoyed using this no-hassle weather station and hope to continue to use it for a long time to come. No batteries to charge or separate solar panels to mountįrom the ease of installation and the usability of the app to all the data that is collected and available in real-time, the WeatherFlow Tempest smart home weather system is a dream come true for any weather buff.The app also sends your device notifications about lightning strikes, rain start, and more. Some ideas would be to turn on the AC or water sprinklers based on the temperature. You can also use IFTTT to perform actions based on AirTemp, Humidity, Pressure, WindAvg, WindDir, WindLull, WindGust, Rain, UV, Brightness, solar radiation, and LightningStrike. You can use the Alexa skill and Google Home actions to report the weather and temperature info through your smart speakers. How cool is that? I say it’s very cool! Other features When well sited and calibrated, the haptic sensor can measure rain accumulation very accurately (90-100% accuracy in Tempest and 80-100% accurate in SKY) compared to accumulation measured by a conventional rain gauge, which should also be well sited and co-located.Ī conventional rain gauge can be highly precise but a haptic sensor is able to provide details on rain start time, event duration, relative intensity and rain rate at 1 minute resolution! Not to mention there is no need for the user to manually collect data after each rain event. Well, it actually uses haptics to detect rainfall. You might wonder how the Tempest can provide rain data when there’s no physical rain collection gauge on the sensor.

You can also view the data through your desktop computer by logging into your account through the Tempest web app. For example, you can check past rainfall data, wind speed data, lightning strikes, and more. Even more information can be found on the sensor page by clicking each item.
