@jredner , that's actually what we're struggling with right now. When we first went live, we had an "automatic" mode that basically figured out when & how much to water. It was cool and automatic and smart -- and people hated it. Part of that was because we didn't have enough history & reporting to let everybody know exactly what the system was doing or to modify it, but part of it was just that it worked so different from any other sprinkler controller.
So we are currently working out how best to implement fully smart watering so people get lots of feedback & have lots of opportunities to fine-tune the results. You can expect to see the results in the next few weeks.
In the meantime, we'll take all of the feedback we can get. We know that we don't always have perfect descriptions of people's lawn and irrigation system, so we can't just rely 100% on the math--we'll need people's input as we go. What kind of control would you want to have? Would you rather have something as simple as "water more" and "water less", or would you rather have more precise (and potentially complicated) controls, to really fine-tune the process?
