I received my API from WUnderground and have it set up form my location. I am in Southern California and wonder upon wonders it is supposed to rain this Friday. Will the Zimmerman function:
1. inhibit watering on Thursday in advance of Friday’s predicted rain?
1. No, Zimmerman’s method currently does not consider the forecast of the next day. However it does consider the forecast of today, and the history data from the previous day, so the rain on Friday will have an effect on Saturday’s watering time.
2. The method calculates a percentage value. So whether it will completely stop the watering on (to 0) or not depends on how much it rains.
