From the web interface, go to the Home screen. Right under the weather icons you should see “weather Station” with an arrow. When you click on that you will see the one’s available and the one you are using. Click on more info, and you will be able to see what that station is reporting.
From the IOS app it’s a little different to get to it. Click on More, then controller settings, then weather intelligence plus, then weather station, then you will get to the screen that shows the available weather stations and which one you are using. (At least that’s how I get to it on my iphone now. — I have NO idea why it changed to be so complicated on the mobile app. Sigh …)
