@crewcrews Ok got it. Yes those restrictions, and restrictions in general, are usually, fairly arbitrary.
Our new software (2.0) coming out in May will have a new concept called flex schedules. We will only water when our depletion algorithms determine based on weather data. So in your case, you would opt-in for Tuesday, Thursday, and Saturday and we will only water on those days, when the yard is moisture depleted. Stay tuned!
