I don’t understand. CyanogenMod 13 introduced new Weather widget and lock screen support. Great! Unfortunately, the widget requires specific providers for weather services and CM does not provide any in the default installation. There exists Weather Underground provider, which works, but only other provider I found (Yahoo! Weather provider) does not work with my CM without Google Play!.
I would a way prefer OpenWeatherMap provider, but although CyanogenMod has the GitHub repository for one , but no APK anywhere (and certainly not one for F-Droid). Fortunately, I have found a blogpost which describes how simple it is build the APK from the given code. Unfortunately, author did not provide APK on his site. I am not sure, whether there is not some hook, but here is mine.
