There are also suggestions to have separate watering times for any zones that have advanced settings like a custom area.
I understand that, currently, if multiple watering times are scheduled to start at the same time, one watering time finishes completely before the next starts, even if that means there is dead time, as Kolraw is experiencing.
It seems, though, that this doesn't need to be the case. At least, it should be easy to interleave two cycling watering times with simultaneous start times, then we could have custom zone attributes and still not waste soakings minutes during prime watering time by not running another zone.
That's what I figured would happen, until I read the article that stated otherwise
