I'm using PH since a month now and still discovering some of its feature nevertheless, using the board and TonyNo weather script I was able to:
- Grab all information from my weather station published here: http://www.wunderground.com/weatherstation/WXDailyHistory.as p?ID=KMNMINNE34
- store the information in global variable
- creating a moving 7day variable with the sum of rain and sum of water the sprinklers distributed.
So as per this weekend watering occurs if:
- my backyard wind is lower than 10mph and wind gust lower than 20mph
- it's not raining
- if the total of water received (rain + sprinklers) in the last 7day is less than 1 in
- if the 7day is higher than 1 in - amount of water for one cycle, the cycle time is reduced proportionally.
If the wind pickups during watering, it's delayed by 5 min. After an hour delay, the watering is cancelled.
I'm still struggling with naming convention. When using things like: '[Local1]', "[LOCAL1]", [LOCAL1], {WATER_TOTAL}, '{WATER_TOTAL}', "{WATER_TOTAL}" etc...
But between trials, the famous "!" and WATER_TOTAL has been updated to 0.7812 (yeah) I made it 
Thanks to the board for the constant help.

That's awesome! I've only recently purchased and begun DIYing some automatic sprinklers, but have hopes and dreams to getting to the point where you are right now.
How are you measuring the sum of water produced by the sprinklers? Do you actually have a device that is catching and measuring rain/sprinkler accumulation, or are you calculating it based on the wunderground info and some metric you devised to estimate how much the sprinkler is putting out?

That's very easy :) the tool is a simple pot or any flat bottom kitchen recipient. Place it in your lawn, run the sprinkler 15-20 minutes. Place the pot on a leveled surface and measure the height of water. Divide by the time the sprinkler ran and you have the equivalent amount of water in inches per minute that you work with.

You call that home automation?! ;)
Over the winter I added a one-wire temperature sensing network to my house. Since I don't yet have the sprinkler system online, I haven't done this yet, but I'm thinking that one day I'll add a soil moisture sensor to that one-wire network which can then be read by PH which can then, based on the actual moisture levels, decide when to trigger the sprinkler system.
But until then, I suppose I'll just keep trudging out with my "simple pot or ... flat bottom kitchen recipient" and turn the sprinklers on by hand. :)

Yes, you do measurement once with what you have then you let PH do the job for you

I went there and tried few sensors but I wasn't very satisfied with the cheap ones and I'm not ready asking my wife to spend thousands in a sensor network but that would be great.
