The retained reference is $349 current direct U.S. price. Confirm the 2026 replaceable-battery generation, included hub, mount, current warranty and home-use terms rather than used first-generation hardware. Confirm the final mount, safe access, account, exports, warranty and replacement-sensor plan before payment.
Current market
Each line carries its own check date because price, software, specifications, and product cycle do not age at the same speed.

Tempest is the best defended route when a compact array, API, broad smart-home integrations and no physical console fit, provided haptic rain, cloud dependence and one-mount exposure are accepted.

What changed
Older observations stay in the ledger when the current view changes. That lets a buyer tell the difference between an old complaint, an active issue, and a problem that was corrected.
Tempest Weather System was checked against current manufacturer identity and U.S. price, exact manual or specification, support and connected-service path, independent editorial or meteorological evidence and bounded owner evidence.
Each amount stays tied to its source and capture date. Conflicting prices remain visible until the seller resolves them.

Owner experience
Owner evidence is retained as a setup, siting, connectivity, maintenance and service checklist for Tempest Weather System, not an accuracy, reliability, forecast-skill or safety rate.
Reports are self-selected and span different generations, sensors, calibration, mounts, terrain, obstructions, weather, radio paths, routers, accounts, firmware, maintenance and ages. They cannot prove reference accuracy, official status, forecast skill, population reliability, lightning safety, service rate or outcome.Self-selected exact-system owners discuss exposure compromises, comparisons, radio and Wi-Fi reach, console or app behavior, maintenance, failures and support. These anecdotes are configuration-specific and do not establish accuracy, reliability, forecast skill, official-observation status or failure rates.
Verify that app-first operation is acceptable during an internet outage and commission rainfall and temperature against appropriately exposed references before automating on them

WeatherFlow identifies Tempest 2026 as a compact solar station with ultrasonic wind, haptic rain, temperature, humidity, pressure, UV, solar and lightning sensing, using an included Wi-Fi hub, app, cloud and published API instead of a physical console.
WeatherFlow lists the current Tempest system with outdoor device and required hub at $349. Confirm the 2026 replaceable-battery generation, included hub, mount, current warranty and home-use terms rather than used first-generation hardware
Tempest measures temperature, humidity and pressure plus ultrasonic wind, haptic rainfall, UV, solar radiation and lightning activity. The lightning channel estimates event distance and is not an official alert, strike map or life-safety instrument. The outdoor unit sends frequent sub-GHz observations to the included hub, which uses 2.4 GHz Wi-Fi for cloud and app service. Sensor cadence, hub radio, local UDP stream, cloud record and forecast update are distinct and can fail independently. Retain the current Tempest specification tables and environmental limits for each channel, including ultrasonic wind, haptic rain and lightning boundaries. WeatherFlow's machine correction and forecast inputs do not convert a poorly exposed sensor into a reference observation.
Keep the mount rigid and level, clean acoustic and optical areas, maintain solar exposure and compare rain over multiple events. Do not tune one storm in isolation; record battery, firmware, siting and algorithm changes that can alter continuity. Never install or troubleshoot aloft during wind or thunder, and keep the pole clear of utilities. The lightning sensor does not replace NWS warnings; confirm the two-year home-use warranty, battery procedure, hub replacement, API continuity and support boundaries.
There is no physical console. Current readings and history use the Tempest app and web service, while documented local UDP and public APIs support integrations with their own limits; setup, forecast and full archive remain more cloud-dependent than the local packets suggest. WeatherFlow presents normal personal-station app, history and API access without a required recurring subscription. Account, precise location and station data are processed in the cloud and may be shared publicly when enabled; review API tokens, integrations, retention and deletion.
NWS gives separate temperature and humidity, anemometer and rain-gauge exposure objectives and explains the compromises common at residential sites.
The NWS CWOP guide covers calibration, siting, accuracy, upload and quality-control boundaries and does not treat typical personal stations as climate-quality instruments.
CWOP accepts properly sited private-station data through compatible upload software and subjects it to network processes; participation does not make a station an official NWS observation.
NWS lightning safety directs people indoors when thunder is heard. A consumer lightning sensor, app or forecast is not permission to remain outside or climb a mast.
Independent hands-on editorial coverage assesses the exact Tempest system's installation, app-led use and sensor approach. It does not prove rainfall algorithms, forecast skill or accuracy at another site.
Self-selected exact-system owners discuss exposure compromises, comparisons, radio and Wi-Fi reach, console or app behavior, maintenance, failures and support. These anecdotes are configuration-specific and do not establish accuracy, reliability, forecast skill, official-observation status or failure rates.

Manufacturer identity, exact current U.S. price, specification or manual, support and connected-service path, independent editorial or meteorological evidence and bounded exact-system owner evidence were checked on August 19, 2026. This market covers complete current U.S.-supported residential and prosumer weather-station systems with meaningful outdoor sensing plus a console, gateway or supported app and data path. It excludes single thermometers and hygrometers, sensor-only accessories, unsupported imports, airport, research and municipal reference systems, agricultural-only packages, OEM rebadges, cosmetic bundles and sensor packs or console choices that do not materially change measurements, siting or data ownership. Preserve the exact sensor suite and absent channels; temperature shield and ground cover; wind height and obstruction; rain-gauge height, level, splash and wind loss; radio frequency, range and channel-specific update interval; console, gateway, local storage, cloud, API, public sharing, retention, subscription and offline behavior; battery, solar, mains and heater power; expansion channel limits; manufacturer-stated range, resolution and accuracy; calibration, aspiration, cleaning, moving parts and firmware; mast, roof, ladder, lightning, overhead-line, low-voltage wiring and grounding exposure; warranty, repair, replacement parts and service region. One integrated array usually cannot satisfy ideal NWS temperature, wind and rain exposure simultaneously. Consumer resolution is not accuracy, calibration cannot repair bad siting, a local pressure-trend icon or maker algorithm is not a guaranteed local forecast, lightning detection is not a life-safety warning, and private observations are not official NWS, FAA, climate, insurance or legal records. No station, price, sensor claim, app, history, API, forecast, owner report or network upload guarantees local forecast accuracy, warning delivery, official-observation acceptance, crop or property outcome, safety, uptime, connectivity or service response.
