I have more details… Looking at the log, I see that the percentage offset based on the Zimmerman method returns, to me, unexpected values, depending on the time of day it checks. I’d expect that the percentage offset would be the same all day based on yesterday’s weather and today’s forecast. It appears that the calculation is done based on the current temp, not the forecast high for the day, which would explain why programs set to run early would end up with no watering time after the offset, and programs that run later have >100%. Where can I get more info on how this Zimmerman method calculates the offsets? The code isn’t part of OpenSprinkler.

3rd value is % offset of run-time for the valves
