Sorry if this is duplicated elsewhere. I looked through all of the product suggestions and didn't find any threads that mentioned it (though the OP on this one has a similar idea; http://community.rachio.com/t/no-water-option-when-sun-is-out/1688).
I would love if there was an option for multiple watering windows (with start and stop time). My neighborhood has restrictions where I can only water during certain time windows (say MWF, 6-7). Ideally the system would take the zone info (soil, slope, head, etc), and allowable watering times then water however it sees fit depending on weather, etc.
It could water whatever zones it had time for in one window, and more in the next if it runs out of time. I'm sure in some cases the windows could be too restrictive for the system to water your yard enough and it would constantly be playing catch-up. If that's the case, maybe it would notify the user. That way the user would know its doing everything it can and that the Iro is basically watrering during the full extent of all of available watering windows.
I hope I'm making sense. I guess you could think of it like automatic scheduling within a users time limitations. I'm sure its much easier said than done, but would be fantastic if you guys could implement something like that!
That said, thanks for the awesome work you guys do and being so available and responsive on the forums. I love that you guys listen to outside ideas and keep adding features!
