I may have uncovered a bug regarding skipping a scheduled watering due to past and future predicted precipitation. We have had heavy rain this week and more predicted for today, my controller alerted me yesterday that both zones I have would be skipped appropriately. I noticed this morning that the decision of the software changed over night and one zone ran - needlessly - while my other zone did not appropriately. I have not seen this behavior before. I am a bit concerned as I trust the weather skip to do its thing and not have to worry about needless watering. The only interesting part is the rain sensor did change to allow for watering last night also. Therefore, I am not sure why after inches of rain and more predicted and effective prior skips this week this happened. See image:
