Hello,
How can I insure Weather underground is what my controller is using? Assuming it is already, can I ascertain what station the weather is being pulled from? Thank you.
What controller version are you using? If you are using a Rachio 3 controller you can choose between using Weather Intelligence Plus or select a preferred weather station (PWS). You can verify the settings you are using by selecting More from the lower right corner -> controller settings -> weather intelligence -> weather network.
And here’s a link on how to select a PWS.
