The weather call is made every 2 hours:

Regarding the error ‘Building Weather History”, I just became aware of the weather call error: this has to do with the daylight savings time change yesterday. Apparently our current script has a bug that if DST is not accounted for, then the next day it returns an error that it didn’t get sufficient 24-hour weather data from yesterday. This should resolve itself by midnight today once we are outside of the 24-hour window. but obviously we will fix it so it doesn’t happen again next year.
