i have an issue with the Zimmerman method of OpenSprinkler. I’m running the newest Version of OSPI (did a git pull yesterday).
The last couple of days it rained a lot. The WebIF showed 0% watering.
My first Station runs on 9PM -> ignores rain – running normal
All other Stations are running later than 1 AM until 7AM during the night. -> The Stations are running even if the WebIF showed 0% watering (they don’t ignore rain by settings).
Might it be possible that the Zimmermann Method goes back to 100% watering at 0:00 AM?
It’s possible however I would check the log data to rule that out or in. Under the table view of the logs page you will see a water level average under each day. This might shed some light on the issue. Let us know what you find.
Samer after midnight the data for daily averages resets on the weather sites, though historical data should balance this out it may be a factor. Also there is a brief period after midnight and before the first update where some of the data is absent or null. If you are checking once per hour this may allow invalid data to persist for the first hour of each day.
Just a couple hypotheses, but looking at your code and the Zimmerman calculations, I don’t see where it should water at 0%…unless maxemanuel is seeing the 0% after it watered, and it watered based on another percentage/data set, which of course the log data would reveal.
