The most advanced
home weather station
ever created

This is not your grandfather’s weather station.

WeatherFlow Smart Weather Stations feature a revolutionary design with no moving parts to wear out, completely wireless operation, simple installation, instantly online, app-enabled, flexible data APIs. The proprietary sonic anemometer out performs and out lasts traditional spinny cups. Our haptic rain sensor can feel each rain drop allowing you to receive alerts the instant it begins raining, determine relative intensity of rain, and know the exact number of minutes of rain each day. The station also reports brightness, UV index, solar irradiance, temp, humidity, pressure, lightning up to 25 miles away, and a slew of other nerdy weather data.

Backed by the WeatherFlow network and proprietary Continuous Learning algorithms, these are the only stations in the world that auto-calibrate daily and directly feed applied machine learning models to improve forecast accuracy at your exact location.

  • Works with Amazon Alexa, Google Home, IFTTT and more
  • Instant lightning strike and rain alerts
  • Precision sonic anemometer and haptic rain sensor
  • Continuous Learning system prevents sensor drift
  • AI / Machine learning improves forecasts over time
  • REST API and local data access via UDP and BLE
  • Free iOS and Android apps
  • Free personal weather webpage
  • Direct feed to WeatherUnderground
  • Integrated with ISY, HomeAssistant, and many more

  • WeatherFlow SKY

    Encased in SKY’s eye-catching design, our revolutionary sensors detect rain drops in an instant, give accurate real-time wind speed & direction, and measure sunlight (including UV Index) - all with no moving parts to wear out or fail. Long range wireless connectivity. Solar power optional.

    WeatherFlow AIR

    Protect your family when AIR detects lightning & warns you of approaching storms. AIR also measures temperature, humidity, and atmospheric pressure. Long range wireless connectivity. Extremely long battery life.

    Wireless Connectivity

    AIR and SKY connect via long range telemetry to an indoor receiving hub. The hub then publishes data to the cloud via your home WiFi network and/or locally to your iOS or Android device via Bluetooth Low Energy. The hub also broadcasts data locally via UDP for direct raw data access.
