The WeatherFlow WiFi HUB is an essential component of your Tempest Weather System. The WiFi HUB collects data sent wirelessly from the sensor devices (Tempest, SKY & AIR), performs onboard algorithmic data conditioning, and publishes the data via WiFi, UDP, and BLE. One HUB can handle 12+ sensor devices at the same location.
The HUB is included with all complete weather stations. This product listing is for a WiFi HUB only (not a complete weather station) and should only be purchased if you need to replace your existing HUB.
