Why do I want a weather station at my house?
Most weather apps and weather reports from your evening news are based on public domain data — primarily from weather stations installed long ago at regional airports. Having a reliable weather station at your home gives you the benefit of knowing the exact conditions outside, (not at the nearest airport). Tempest also provides hyper-local forecast info, customized to your location and can even help you save money on heating & air conditioning by allowing your smart home tech to make automated decisions based on real-time weather data.

Can I see my Tempest data online?
Yes. Once your system is configured (using the Tempest Weather mobile app on iOS or Android), you can view data and forecasts from any browser at tempestwx.com. Log in to the website using the same credentials you used to create your Tempest account or view the station data as a guest user.
Do I need WiFi to use the Tempest System?
It is highly recommended to connect the Hub to a WiFi network. Doing so will enable continuous uploading of weather data and allow anytime data access from anywhere.
