Poor Design

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.

Good app needs temperature alerts

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.

Bad WiFi

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.

Worst forecasting

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.

This app hallucinates

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