Zone running without schedule

I have rachio 3 and I only have 1 valve wired and have the zone set up for it.
The only zone was running without anything scheduled for at least a week ahead but it is still running and the recent run is not recorded for the zone on rachio app. I ran via schedule on 5/4 and watched the ground dry up for hot weather. On 5/5, I noticed wet ground in the zone. I watched the area dry up again and noticed wet ground again on 5/6 while rachio app only shows zone ran on 5/4.
I just now disabled the zone to see if it helps. Can you tell me what is going on?

Are you sure you didn’t inadvertantly set up a fixed schedule that is running on the zone? When you click on the “more” on the bottom right of the screen, and look at history, there is NOTHING showing?

It shows “Schedule Completed” for 5/4 as the top (last) entry but nothing for 5/5 or 5/6 even though ground became wet from very dry on both days.

Are you sure the wet ground is not because of dew? After watering there’s moisture in the soil and dew can build up quite a bit if overnight temps lower quite a bit. That’s all I can think of.

This is happening to me as well. I am sure it is running an old schedule when grass was new on a few of our zones that is not listed and not showing in history. I removed all deactivated schedules and no luck. What is the best way to reset the controller? Gosh we have been wasting so much water as a result. Thanks-

If there isn’t something showing in history, then Rachio isn’t running it. If you have a zone that is running without the controller reporting it, it is one of two things.

There is a short in the system wiring and the zone is getting the milliamp signal from another zone set to run.

Or, if the diagram in the valve is damaged or failing, the reduced pressure caused by another zone running on the system can actually activate the valve.

Thank you for the reply. There is no other activity on the system when this zone activated. Could there be another thing causing a short or pressure issue? Debris on the solenoid / valve or something?

It would be an easy check to take apart the top of the valve to check condition of the diaphragm.

Have you physically seen the zone run?

I will check that out thanks. I haven’t seen it, but my wife has heard it and the backyard grass and nearby concrete are always wet. And the front yard is dry. Thank you-
