Above is a link to an old discussion. I messaged Franz with the following message and he requested that the message go to this board so all can benefit. The message is as follows:
Hello! I know the link above is an ancient (in Rachio development terms) discussion, but I am hoping you might help me understand some things better.
I have read a great deal about crop coefficients etc. It seems that what is “ideal” for one month might not be for another and so things are generally averaged. In my case I must average things for late April-October (anything else, my sprinkler lines are blown out).
At anyrate, here are my questions:
In the post I linked to, you mentioned that with a flex schedule, the “Advanced” settings for crop coefficient are ignored. Is this still true? I run a basic flex daily schedule and have noticed that when I change the crop coefficient, I noticed that it does change the soil moisture (and therefore the watering frequency).
In that post, you noted different crop coefficients for different months. Does the Rachio include these adjustments automatically when running the basic flex daily schedule?
2.5) If so, why did changing the coefficient in “Advanced” change the measured data as I mentioned in questions 1?
Ultimately, I guess I want to understand how the system manages crop coefficient when running the flex basic schedule so that I can ensure my system is not only keeping my lawn green (which it is doing) but also encouraging the roots to go deep so to speak. How’s it work ?
Right now, it is certainly keeping the lawn green, but after I adjusted the crop coefficient to .87 (thinking it to be a reasonable average for the months I run), it seems to run quite a lot even when the temperatures are not particularly high (65-78 degrees). I have not kept up on the software changes of the last couple years where this matter is concerned.
Thank you for any help you can provide. I would have gone right to tech. support, but your old post with the monthly crop coefficients and the associated discussion really fit with my questions - and added a bit to them .
