Samer has already implemented the California Water Restriction and this will become available when firmware 2.1.4 is released. We are finishing up this new firmware and have been working on internal testing. Hopefully it will be released in a few days.
Regarding WaterSense: getting the certificate requires implementing ET-based water adjustment algorithm, and I assume the approval process will take several months, so I don’t foresee this to be completed within the next few months. Sorry.
