I can't recall exposing that functionality through our app, so you might be losing your mind
You can use our remote to run one individual zone for an amount of time, or run multiple zones for a known amount of time. If you enable water hammer on the device it will keep the first running zone on for 10 seconds while starting the second zone.
Hope this helps. Someday I'm sure we will add zone skip to the app.
Maybe someone can help with the dos and don'ts around sprinkler blowout, unfortunately I can't help there.
