To add my 2 ¢ to the restarted thread, Rachio offers a dedicated “Delay between zones” cycle and soak setting if and only if Advanced Wiring (M terminal) setting for the controller is set to “Well or Pump start relay”.
This feature was released on April 4th (link)
For someone with an indexing valve, it may be confusing that they have to choose well pump setting instead of the master valve that they may actually have.
Alas it also doesn’t address the downside that indexing valve will not work with a flex daily schedule, which is the Bee’s Knees option of schedule types.
