Ray, I hope you’re still monitoring this thread. Since WU doesn’t provide what’s necessary, my weather program is now calculating ETo and WL range 0-200. It updates WL on OS once per minute. Thanks for the nice API! @Roger had some nice posts from a similar high desert location.
Question: if WL changes, is each station’s duration updated while running or in queue? If it starts raining during an active sprinkler program and ETo backs down, my program will update WL accordingly and hopefully change the durations.
Thank you,
Randy
PS, for me, Water Demand makes a good mental image.
