The data from my weather station is uploading to Weather Underground but the data does not show up on the app on my iPhone
Ensure that you have the latest version of the app and console firmware installed: Where do I get the "WS View" application?
Ensure that the station ID is listed in ALL CAPS in the application. If it is not, go back into WU setup and correct and/or remove the listing with lowercase from your WU stations and replace with uppercase.
Refresh the screen by pulling down on it, you should see a progress indicator as it reloads the data. If this does not work, turn off WiFi and refresh connected via phone data only, or if possible change WiFi networks. This issue is usually caused by network connectivity problems.
