I just pulled the latest version of the code on Dan’s Github (https://github.com/Dan-in-CA/OSPi) and used your location: “Grafrath,Germany” which returned “rain” weather code triggering a rain delay when using Weather Underground. Going to the homepage shows the rain delay is in fact set.
However, when using Yahoo! weather I noticed two things. One I have a bug preventing Yahoo weather from triggering a delay. I just pushed a fix to Dan’s repo and hopefully have that merged in soon. Second, your location right now on Yahoo weather is returning “cloudy” (code 28) which would not trigger the delay anyways.
Thanks for the information. I also found a bug preventing weather from being shown in your location on the mobile app and have already issued a fix for it for the next version.
