I have an OsPi running the latest software…I am not sure when this happened, but no watering is happening at all for any scheduled program. I can run the scheduled program manually, and all stations run as they are supposed to….the calendar shows that a program should run….but no automated program runs on the specified time. The system had been running just fine, so I really don’t know what changed (maybe a power cycle)….but really, everything looks to be fine.
Is there some special process that gets called to run an automated program that is different from a manual program run, possibly?
Some other possibilities: have you set it to use weather (either Zimmerman algorithm or auto rain delay)? If so, it could be that the weather algorithm returns 0% watering, preventing programs from running.
