Once again you are missing the point to the study because of your incessant need to be brilliantly dumb.
Some Texas cities and water purveyors are now mandating smart
controllers. If these controllers are to become requirements across the state, then it is important
that they be evaluated formally under Texas conditions.
The issue of being able to tweak a smart controller is not the purpose of the study. If you would like education on that I suggest you attend Guy Fipps water auditing course among others. The issue of the study is whether smart controllers can be considered a water conservation tool in Texas using the parameters and sensors provided by the manufacturer. If they don't then the manufacturers need to keep improving on the necessary parameters as they have done from previous studies. If the claim is that this is not possible then fine don't mandate them.
