The Tempest Weather System by WeatherFlow is a complete smart weather station that pairs an all-in-one outdoor sensor with an included Wi-Fi Hub. The outdoor unit measures temperature, humidity, wind speed and direction, rainfall, barometric pressure, solar radiation, ambient light, and UV, and it includes built-in lightning detection. Ultrasonic wind sensing and haptic rain mean there are no wind cups or tipping-bucket parts to maintain. You view conditions in the Tempest app and can connect the system to supported smart-home tools — without needing a separate physical display console.
Specifications and compatibility notes are based on manufacturer documentation — not independent Atmosiva testing.
Known limitations
- •Amazon ASIN B0868WY7NY is the complete Tempest Weather System listing (outdoor sensor + Wi-Fi Hub + mounting/base hardware) — not a sensor-only SKU
- •No physical display console is included; viewing is via the Tempest app and supported smart-home integrations
- •Wind 0–100 mph is a documented measurement range, not a survival rating
- •Lightning detection is documented up to about 25 miles / 40 km
- •RainCheck / NC Rain is a cloud-assisted enhancement for improved rain estimates; the outdoor unit still measures rain with its haptic sensor when cloud assistance is off or unavailable
- •Smart-home and cloud partner availability (Alexa, Google, IFTTT, Shortcuts, and others) can change over time — verify current WeatherFlow integration docs
- •Atmosiva does not claim Ethernet on the current retail Hub; confirm ports on your unit if wired LAN is required
Pros
- + Complete all-in-one outdoor sensor in a single housing
- + No mechanical wind cups or tipping-bucket rain gauge
- + Built-in lightning detection
- + Solar powered with internal LTO battery
- + Wi-Fi Hub included in the retail bundle
- + App and smart-home support with no mandatory subscription for core use
Cons
- − No physical tabletop console included
- − Fixed sensor suite — less modular than Ecowitt-style add-on ecosystems
- − Haptic rain estimates may benefit from RainCheck / NC Rain cloud-assisted enhancement
- − Hub connectivity is Wi-Fi based — do not assume Ethernet on the retail hub
- − Premium price versus basic display-first weather stations
Technical Specifications
Ultrasonic wind sensor with 0–100 mph documented measurement range — not a survival rating
