Flex daily schedule help needed for Texas and warm season grass

Thank you for the information. I had changed the root depth because it is St. Augustine grass and I thought the roots were much shallower than 9 in. Is this the correct setting or should I leave it at the default. Also where is the bucket size you are referring to so I can reference it and adjust?

I am wanting to make sure the lawn stays green and healthy as I had some winter die off I am trying to get back green again. I know I can either reseed or wait for the healthy areas to spread to it.

I set the soil type based on a site I found in the forums here to determine your soil type. https://websoilsurvey.sc.egov.usda.gov/App/WebSoilSurvey.aspx

This yielded Silstid loamy fine sand, 1 to 5 percent slopes 0.08 (rating) was the soil type set correctly on the account or did I choose the wrong kind? 83.1 % sand, 9.4% silt, I wanted to get as specific as possible to get the most out of the smart aspects of the system. If I understand right the .08 refers to the AWC. What should I set this to in the app to corespond?

Appreciate the help.
