Are you using the web application hosted by Ray at http://rayshobby.net/apps/sprinklers? If so, those updates have to be pushed by Ray and sometimes take a day or two. I email him the updated package daily and he usually pushes it within 12 hours.
Glad your enjoy the app 🙂
Edit: I just checked and the version on Ray’s site still has the weather bug. It should be fixed once updated and also get the new status page and other fixes/changes.
For future reference, you can find the version in the About page accessed from the side panel. Currently, Ray has v14 and the latest is v15.
