Turn Your Smart Home
Into a Genius

Trigger your outdoor lights based on the actual brightness of the sky. Enable your thermostat to use the weather conditions outside your home to conserve heating and cooling use.

Do something about the Changing Weather

Tempest data, along with all our real-time useful information, is part of data sets which are shared with the National Weather Service (NWS-NOAA) and other met agencies across the world, supporting their mission of predicting dangerous weather and warning the public of potential risks. As forecasting becomes more difficult and weather patterns increasingly unpredictable, each Tempest helps contribute to a better global forecast.
