Gen3 schedule didn't run (due to rain sensor)


#1

The title says it all. I had a schedule set to run this morning before the sun came up. It didn’t water. Maybe I’m doing something wrong?


#2

Do you have a rain sensor? Is there anyway you can look at your history feed and see what it says before your schedule was about to run?


#3

The rain sensor was activated and immediately deactivated.


#4

What kind of rain sensor do you have? Can you post a photo of your rain sensor’s wiring?


#6

Are both of the black wires a part of the sensor? Are the white and red also from the sensor?


#7

The black ones are the sensor wires. I went 1 to 1 from the old controller to this new Rachio one.


#8

Can you let me know the brand?

We have a few different sensor wiring setups for the different types --> https://support.rachio.com/hc/en-us/categories/115001606387-Sensors

I’ll take a picture when I get home. I’m unsure of the brand. Thanks for the link.


#10

Please let me know what you find. Definitely want to get this solved for you.


#11

I verified and the rain sensor is currently activated which will not allow schedules to run.

:cheers:


#12

Well I guess I’ll need to figure this one out. I’ll post the picture when I get home. It’s two sensor cables and the link that was shared mentioned not to plug both in.

Here’s a picture of the sensor: https://photos.app.goo.gl/UmMfKCPn4mfJErzR7

If it is just two wire, one should go into S1 or S2 and the other should go into -24 VAC.


#15

Yep. Just now figured that out per that link and tested it. This is solved. Thanks for the help.


#16

@the901Very glad to hear it got resolved. Enjoy your Rachio 3!!


#17

The more I get familiar with it, the more I’m liking it. Thanks again.


#18

I have this same issue, constant cycling of the rain sensor. This is a three wire, plus the 24v.

Any thoughts most welcome.


#19

@golfbravo - what make and model of rain sensor? Can a picture of the current wiring be posted?

See this post where swapping the VAC wires was the solution:


#20

Here are pics of the sensor and the wiring. Three wires yellow, brown & white (plus 24V).

I wired it as per the old system

Cheers

@golfbravo - move the white wire in S1 to the 24VAC - terminal and in the app have nothing connected to S1 and the rain sensor connected to S2.
