Sorry, I should've been a little clearer. I was asking about a friends Rachio. He lives approximately 20 miles east of me and he was the one whose weather station recorded 0.24" of rain. Either way though, I believe this answers the question.
My logic seems to be correct that if the rain doesn't fill the moisture balance to the level needed then the irrigation will run the zone but it will need less water as the precipitation helped "refill" the moisture balance. Can you confirm my thinking is correct and Iro is using the same logic?
