In the past I had a simple timer. Set frequency and duration. I don’t need\want advanced settings. I think you are looking at it from a irrigation master level. Someone who like the ability to customize.
Let me change topics really quickly. Lets talk cellphones… When my parents were in the market for a smartphone I quickly said get an iPhone. Its simple and easy to use even for the most technology challenged individual. Yes Android has the ability to customize until your hearts content but for some people simpler is better not only for you but for them.
Kubisuro. Maybe its my ignorance on this topic but in my simple minded head it seems like the a little bit of data could go a long way. Even if it was part of the monthly seasonal shift email. Three feedback buttons, Too Wet, Too Dry, Perfect. If you click it you are feeding your zones with more info. Digi Brain “It was a hot month and user said Front Grass was too dry…If its the same temp or hotter lets increase watering duration” Not to complicate things but what about add a run off also. “Too Much Runoff” Digi Brain "It was a hot month and user said Front Grass was too dry and also said Too much Run off. Increase watering days and decrease time or maybe add smart cycle. Seems like after a season the timer could use that data to adjust times and there you have the lazy mans smart sprinkler timer.
azdavidr: I would agree those first few settings could get your into trouble but. In my case did take the time to feed it as much correct info as possible on the main screen. I looked up my soil type and I looked up my sprinkler heads. IE Rotor\Spray. I am certain all the info on the main screen is correct.
Thanks for the info on the crop-coefficient. That will come in useful. Need a little question mark button next to each of those advanced settings that explains. Yes, I am aware you can go into the help and read about it.
As for my timer I have an older smarter brother who looked at my settings and steered me in the right direction …I hope. He also pointed out a somewhat hidden feature to me. The ability to fill or empty the soil moisture. That will help immensely.
