## What is Tempest Weather?

This app requires the Tempest sensor device, which is available to buy separately.

Need to set up and configure your Tempest Weather System? The Tempest app will walk you through a few simple steps, including connecting your home’s WiFi network. Once you’re up and running the app will quickly become your go-to for real-time weather conditions, lightning and rain alerts, and the most accurate forecast for your location - guaranteed. 

Data available in the Tempest app includes: 
Temp, humidity, dew point, feels like, heat index 
Barometric pressure, sea-level pressure, trends 
Lightning detection and alerts up to 40 km
Wind, UV, solar irradiance 
Rain rate,  accumulation, rain onset alerts
10-day forecast 
Historical weather data graphs


Smart Home Ready:
Use this app to save time, energy, and water by integrating with popular smart home and irrigation services. Use your weather data to optimize heating and cooling, adjust your irrigation schedule, and alert your family when lightning storms approach. Tempest is compatible with Google Assistant, Rachio, IFTTT, Siri, Alexa, Homey, and many more.

Weather Geek Worthy:
The Tempest device features an all-in-one sensor and long-range wireless connectivity (1000ft), sonic anemometer, and haptic rain sensor, but it is far more than just a cutting-edge piece of hardware. Each Tempest leverages WeatherFlow-Tempest’s patented Nearcast Technology™, which feeds real-time observed weather data from your backyard into a machine learning system to dramatically improve forecast accuracy where it matters most.

### 4/5 — Rainfall Rate on the Current Conditions

*2026-07-19*

Can y’all add the rainfall rate instead of the day before’s rainfall 
     So instead of it showing yesterday’s rainfall it would show the running rainfall rate like: 2.50 in/hr, so that I don’t have to go to the chart to look at the rainfall rate from a few minutes past. What I’m trying to say is keep the rainfall rate more current.
      For the wind speed, could y’all update the graphing system because it doesn’t want to show all of the current wind speed and direction, it just shows the one minute average of the recorded wind speeds and plots them under one minute’s speed like for example, at 1:00PM the wind “speed” was 10 mph where there was more wind and less wind than that. 
     Next, the lightning detection feels and seems off, where it’ll record 5+ strikes in a second or two and then it’ll not be there and it’ll say the last strike was either 1-2 minutes ago.
     Lastly, the radar map will not let me zoom all the way in to my house, if I would try to do this it would push me back about 2-4 miles away, or in other words it would show the rain or snow for another place when I want to zoom into my house close up to see what the conditions are. Could y’all add a feature where it would show the next 1-3 hours radar instead of the previous 1-2 hours, so it would feel like a true past/future-cast. And add a hurricane track where we can see where a hurricane is going to hit.
     So on the next possible update y’all should focus on these things by making the system better and more user friendly. All in all it’s a great system, but with a few things/bugs to be updated. That’s why I am giving 4/5 stars.

### 3/5 — Poor Design

*2026-06-19, version 5.40*

The station data is at the top of the screen and the rest of the screen is the forecast that goes out a ridiculous number of days.…. Plus there are 5 days of old forecasts left on the screen.  Why?  It’s not bad to see the forecast, but it’s not optional - so you can’t remove it from the screen. …. and makes the screen too busy and cluttered for my personal taste.  Other issue is that it does not denote times of peak data…. max wind…. high temp - and it doesn’t give you a start/end time for rain. To be fair there is a graph where you can attempt to obtain the data- but would be great to have that data at a glance.  One final issue….  When I tap on one of the individual data points on main screen…. it brings up another page with all the data and not just what you tap. The wind data on that page is a smaller lighter font than the Pressure and it’s  easy for my eye to not see the decimal point on the wind data-   for example- it’s easy to mistake a wind speed of 2.2 mph for 22 mph.  
I would like to click on a data point where all data for that data point is readily available on one screen …. along with time of the event peaks. 
I don’t expect you to redo your app for me, 😉
Just some food for thought next time you do a revamp.

### 4/5 — Good app needs temperature alerts

*2026-06-14, version 5.40*

This is a nicely designed app with a good user interface. Given that many people purchase a weather station to monitor temperatures, it seems like a big deficit to not have the ability to set high or low temperature alert alerts through the app.

### 1/5 — Bad WiFi

*2026-06-11, version 5.40*

I have over 50 devices on my home network that connected to my WiFi the first time but not the Tempest Weather Station. I have extenders in several locations so signal strength is not an issue. I followed all their troubleshooting recommendations with no luck. So at this point I will be returning it.

### 1/5 — Worst forecasting

*2026-06-06, version 5.40*

Still can’t believe there is no Apple HomeKit integration. Ifttt is $$$ now.
Also, the forecasts are never correct. It’s going to rain in 30 min. Nope now it’ll rain in 45 min. Nope… I give up on this app and hardware.

### 1/5 — This app hallucinates

*2026-06-02, version 5.40*

This app makes up fake data when the sensor fails. Also The tempest hardware is junk, breaks down after a couple of years.

### 1/5 — Base stopped connecting

*2026-05-10, version 5.40*

After many years of use this stopped working - can I connect seams like the hub

### 5/5 — The great weather app

*2026-04-25, version 5.40*

I’ve been using this weather station for almost a year, and my experience has been excellent. The installation was simple, and the data it provides is very accurate and consistent day to day.

I only had one issue during this time, but Tempest’s support team was outstanding. They responded quickly and sent me a replacement station at no cost, which really shows how much they stand behind their product.

It’s a reliable, well-designed system with top-notch customer support. I highly recommend it to anyone looking for a quality weather station.

### 3/5 — Great hardware. Meh software.

*2026-04-19, version 5.40*

I love my Tempest weather station. It integrates really well with Home Assistant and Alexa for hyperlocal forecasting. But the app is really in need of a makeover. It looks like it was made for iPhone 3G… things are arranged properly and it never crashes which is great, but it’s not using any modern design language. I hope to see better widgets and some Liquid Glass effects in the future.

### 2/5 — Seems as though you need to be the owner?

*2026-04-18, version 5.40*

Would be great to view a tempest with a public URL.
