I had a similar issue last July, when the Rachio watered three days after 2+ inches of rain (Rachio 2 Watering after 2 inches of Rain in 3 Days). I made some adjustments from feedback there.
This morning (Thursday the 2nd), three days after 6+" of rain over two days (1.66 on Sunday the 28th, followed by 4.66 on Monday the 29th), the Rachio 2 again ran through a cycle, watering for 98 minutes across six zones. There are spots in the yard that last night (pre-Rachio irrigation) water would come up through my toes as I walked from the 6+" three days ago.
So, looking for some input on what I can change to avoid this.
Because this happened last year with a big storm, I was watching the Rachio through the app to see if it was scheduling anything in the week after the deluge. I was surprised to see something scheduled for today.
Here are screen shots from the day after all the rain:
One Zone example (other zones set similarly, except for size, slope and spray head):
Weather station information:
And today, after it ran:
So, the soil moisture dropped to 0% two days after 6+" of rain.
Ideas on what I need to do with this?
