First, you need to define wheat type of emitter you have. If you don't know what you have, can you take a picture of one of your emitters and maybe we can point you in the right direction. The emitter you have selected is the "out of the box" emitter in Rachio and probably isn't correct. You will need to create a custom emitter.
Otherwise, what does your landscaping consist of? Is it really xeriscape? Where are you located? You probably have sandy loam in the valley.
