Welcome to the forum! I too am a Texas licensed irrigator. I think you’re in the right place for any question you may have about the controller. There are first time users and Rachio veterans here. I have learned that the Rachio users on this forum are or have become the best resources for any question you may have. And Rachio support is the best!
When I install a new controller for someone I always give them a help sheet with several helpful links to this forum. Because when I’m not directly available to answer a question, I know this forum will have an answer.
The community has been around a few years now. Do a search and see if any of your questions might have an answer.
