As many of you know the WeatherUnderground API is being phased out as of  December 31, 2018.

The master branch for PiClock has been updated to replace WU with DarkSky for the forecast data, and RainView for the radar images.

The (long) discussion occured at the github issue page https://github.com/n0bel/PiClock/issues/103

I encourage everyone to upgrade (instructions have been updated for both install and update)

Please post issues at github https://github.com/n0bel/PiClock/issues  It is much simpler to manage issues there, as well as help the community of PiClock users active there.
