@dennis.french, weather1.py should be the only file referenced by the firmware nevertheless I have restored access to weather.py. The reason is the firmware appends the weather algorithm type to the end to request the proper script.
If you are using the 2.1.0 firmware, all you need to do is put a valid location (you may use the lookup feature to verify the location is valid). Once saved, the timezone, sunrise and sunset data should be displayed correctly. From there, you may input a Weather Underground API key and enable weather based adjustments for programs.
