I am trying this device for the first time. I am not sure I totally understand this, but here is what I did:
After setting up the device I entered for source location (key is my WU key):
http://api.wunderground.com/api/key/radar/q/pws:KCASANDI170.png?radius=20&width=280&height=280&newmaps=1
and for destination location:
file:///Users/MacMini/Pictures/WU_Radar_Images
The source location URL works fine in a web browser. But Indigo gives me the plugin error: ... cannot determine age of data. Skipping until next scheduled poll.
What is wrong?
