Exploring the Features of the Weatherflow Tempest

The Weatherflow Tempest is more than just a weather station. It is a smart device that can measure various weather parameters and provide you with real-time data and alerts on your smartphone, tablet, or computer. The Tempest can also integrate with various smart home platforms and devices, allowing you to automate and control some elements of your home environment based on weather conditions.

Temperature and Humidity

The Tempest measures the temperature and humidity using a digital sensor that is located inside the device. The sensor is protected by a radiation shield that reduces the effects of solar heating and wind chill on the readings. The sensor has a range of  -40°F to 140°F for temperature and 0% to 100% for humidity. The sensor has an accuracy of ±1°F for temperature and ±3% for humidity.

The temperature and humidity readings are displayed on the app and web interface in various formats, such as current, daily, weekly, monthly, or yearly averages, highs, lows, trends, graphs, etc. You can also view the heat index, dew point, and wet bulb temperature, which are calculated based on the temperature and humidity readings. You can also set custom alerts for temperature and humidity levels that interest you, such as frost, heat wave, or mold risk.

The temperature and humidity readings are comparable to other weather stations in terms of accuracy and consistency. However, some users have reported that the Tempest tends to read slightly higher than other stations, especially in humid or cloudy conditions. 

Weatherflow is aware of this issue and is working on improving the calibration and correction algorithms for the Tempest. Firmware updates are pushed out as needed.

The temperature and humidity readings can also be used to trigger smart home actions through platforms, such as Alexa, Google Assistant, IFTTT, SmartThings, HomeKit, etc. For example, you can use Tempest’s data to adjust your thermostat, fan, humidifier, dehumidifier, etc. based on your comfort and health preferences.

Wind Speed and Direction

The Tempest measures the wind speed and direction using a sonic anemometer that is located on top of the device. The anemometer uses four ultrasonic transducers that emit and receive sound waves in different directions. By measuring the time it takes for the sound waves to travel between the transducers, the anemometer can calculate the wind speed and direction based on the Doppler effect.

The anemometer has a range of 0 to 125 mph for wind speed and 0° to 360° for wind direction. The anemometer has an accuracy of  ±1 mph or ±5% (whichever is greater) for wind speed and ±5° for wind direction.

The wind speed and direction readings are displayed on the Weatherflow app and web interface in several selectable formats, such as current, daily, weekly, monthly, or yearly averages, highs, lows, trends, graphs, etc. You can also view the wind gusts, lulls, cardinal directions, etc. You can also set custom alerts for wind speed and direction levels that interest you, such as storm warnings or favorable sailing conditions.

The wind speed and direction readings are more accurate and reliable than most other weather stations that use mechanical anemometers that rely on spinning cups or propellers. The sonic anemometer does not have any moving parts that can wear out or get stuck by dirt or debris.

The sonic anemometer also responds faster to changes in wind speed and direction than mechanical anemometers. However, some users have reported that the Tempest tends to read slightly lower than other stations in very light winds, less than 0.7MPH, or very strong winds. This could be due to interference from ambient noise or turbulence from nearby objects.

Weatherflow is always improving its algorithms through feedback from the network of Tempest weather stations and is constantly improving the calibration and correction algorithms for the Tempest.

The wind speed and direction readings can also be used to trigger smart home actions through various platforms and devices. For example, you can use the Tempest’s data to control your smart blinds or shades based on the wind direction or intensity.

Rainfall

The Weatherflow Tempest rain sensor is the most innovative and controversial.

The Tempest measures rainfall using a haptic rain sensor that is located on top of the device. The rain sensor uses a piezoelectric element that vibrates when raindrops hit it. By measuring the frequency and amplitude of these vibrations, the rain sensor can calculate the rainfall intensity and duration based on a proprietary algorithm.

The rain sensor has a range of 0 to 8 inches/hour for rainfall intensity and 0  to 393 inches for rainfall accumulation. The rain sensor has an accuracy of ±10% or ±0.01 in/h (whichever is greater) for rainfall intensity and ±1% or ±0.04 in (whichever is greater) for rainfall accumulation.

The rainfall readings are displayed in your choice of formats, such as current, daily, weekly, monthly, or yearly totals, rates, trends, graphs, etc. You can also view the rain start and stop times, the rain type (drizzle, light, moderate, heavy, etc.), and the rain check feature that corrects the readings based on official or nearby sources. You can also set custom alerts for rainfall levels that interest you, such as flood warnings or watering needs.

The rainfall readings are different from other weather stations that use tipping-bucket rain gauges that rely on a mechanical mechanism that tips when a certain amount of rain is collected.

The haptic rain sensor does not have any moving parts that can get clogged or jammed by dirt or debris. The haptic rain sensor also responds faster to changes in rainfall intensity and duration than tipping-bucket rain gauges.

However, some users have reported that the Tempest tends to read higher or lower than other stations depending on the raindrop size, shape, and angle. This could be due to the sensitivity and calibration of the piezoelectric element and the algorithm used to convert the vibrations into rainfall measurements.  Again, as time goes by, this issue is getting better.

The rainfall readings can also be used to trigger smart home actions like controlling your smart sprinklers or irrigation system based on the rainfall amount or type.

Lightning

The Tempest detects lightning using an electromagnetic sensor that is located inside the device. The lightning sensor detects the electromagnetic pulses emitted by lightning strikes within a radius of about 25 mi.

By measuring the time and strength of these pulses, the lightning sensor can estimate the distance and frequency of the lightning strikes based on a proprietary algorithm.

The lightning sensor has a range of 0 to 25 miles for lightning distance and 0 to 9999 strikes for lightning count. The lightning sensor has an accuracy of ±2 miles for lightning distance and ±10% for lightning count.

The lightning readings are displayed as current, daily, weekly, monthly, or yearly totals, distances, trends, and graphs.  You can also view the lightning start and stop times, the storm track feature that shows the direction and speed of the storm movement, and the storm check feature that corrects the readings based on official or nearby sources.

You can also set custom alerts for lightning levels that interest you, such as storm warnings or safety precautions.

 The electromagnetic sensor does not have any moving parts that can wear out or get damaged by noise or vibration. The electromagnetic sensor also responds faster to changes in lightning activity than acoustic sensors. 

Atmospheric Pressure

The Tempest barometer measures the atmospheric pressure using a MEMS sensor that changes its capacitance according to the pressure applied to it. The barometer ranges from 8.86 to 32.48 inHg (300 to 1100 mbar)  for pressure. The barometer has an accuracy of ±0.03 inHg  (±1 mbar). 

The pressure readings are displayed as current, daily, weekly, monthly, or yearly averages, highs, lows, trends, and graphs. You can also view the sea level pressure feature (absolute pressure)  that adjusts the readings based on your elevation (relative pressure) and temperature settings. You can also set custom alerts for pressure levels that interest you, such as high or low pressure systems.

 Solar Radiation and UV Index

The Tempest measures solar radiation and UV index using a photodiode that is located on top of the device. The photodiode measures the intensity of the sunlight in watts per square meter (W/m2) and converts it into a UV index value based on a proprietary algorithm. The photodiode has a range of 0 to 2000 W/m2 for solar radiation and 0 to 15 for UV index. The photodiode has an accuracy of ±5% or ±10 W/m2 (whichever is greater) for solar radiation and ±1 for UV index.

The solar radiation and UV index readings are shown in the same ways the previously mentioned sensors are. You can also view the solar energy feature that shows the amount of energy produced by the sunlight in kilowatt-hours per square meter (kWh/m2). You can also set custom alerts for solar radiation and UV index levels that interest you, such as sunburn risk or solar panel efficiency.

Weatherflow Tempest forecasting

The Weatherflow Tempest uses a proprietary forecasting software called Nearcast. It begins with weather measurements from the Tempest Weather Station, then incorporates a huge amount of data from satellites, radars, official surface networks, other weather stations, and more. Using these carefully selected data sources, then they run their high-resolution numerical weather forecast models and train the AI-based output models to produce the most precise location-specific forecasts available anywhere. The outcome is a greatly improved forecast for the Tempest’s exact location.

Power:


Four solar panels that can work at any angle of the sun provide energy for the Weatherflow Tempest. The panels only need 4 hours of
sunlight every two weeks to keep running. This makes the Weatherflow Tempest useful in high-latitude places like Canada. The Tempest has a 1300 mWh LTO battery that lasts forever. If the panels don’t get enough sunlight, you can use an extra power source accessory.

The Weatherflow Tempest is Wireless

The Hub receives data from the Tempest device using a low-power 915Mhz radio signal. The Tempest weather station can send data to the Hub from up to 1000 feet away if there is nothing blocking the signal. The range may be shorter if there are obstacles (cars, walls, buildings).

The Hub, Tempest’s Indoor Receiver

The WeatherFlow Tempest Hub is a device that collects and publishes data from the Tempest Weather System. The Hub connects to the Tempest sensor array via radio frequency and to the internet via WiFi. It also performs onboard algorithmic data conditioning to improve the accuracy and quality of the data. The Hub can handle up to 12+ sensor devices at the same location. You can use the Tempest Weather app or web interface to view your weather data in real-time or access historical records. You can also share your data with other users or weather networks like Weather Underground.

The Hub requires a 1 amp 5-volt power supply (included w/Tempest) and a WiFi network. If you live in an area prone to power outages or severe weather,  a Hub Power Bank is available, which is a battery backup that can keep the Hub running for up to 10 hours. The Hub Power Bank also has pass-through charging, which means it can power the Hub while charging itself.

The WeatherFlow Tempest can collect data during a power outage for up to 90 minutes and send it to the Hub when the power is restored. However, if the power outage lasts longer than 90 minutes, the Tempest will lose the data that it cannot store.

The Hub can store up to 7 days’ worth of data from a single Tempest device and restore it to the internet when the connection is restored. However, the Hub also needs a power source to operate, so if the power outage affects both the Hub and the Tempest, the data will be lost.
