I give up. Do whatever way you want.
I need a minimum of a 1 minute and a maximum of 1 day duration for the next 15 years.
That is accounted for in option 3 that Ray suggested.
Also, this won’t be used for the logging output. The controller will still log with a granularity of a single second and report exact usage.
Update: Actually he has a maximum of 7 hours right now. Are you saying you need a station open for 1 whole day? If so, the interval option is available to re-run the program as often as needed to accomplish the end watering goal.
