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

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

timber · May 16, 2018, 2:40pm

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

the901 · May 16, 2018, 2:41pm

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

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.

timber · May 16, 2018, 2:46pm

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

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

the901 · May 16, 2018, 4:52pm

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.

the901 · May 16, 2018, 10:32pm

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

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

the901 · May 16, 2018, 11:03pm

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

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

Any thoughts most welcome.

@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:

golfbravo · July 22, 2018, 8:21pm

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.

See ->

golfbravo · July 22, 2018, 9:35pm

Ok thanks. That doesn’t agtee with the link you provided, I’ll give it a try though!

Cheers

@golfbravo - I think the only difference between the text and the link is the link uses S1 instead of S2. At the bottom is the picture for the Gen 3:

My gen 3 system did not go on , apparently because of the rain sensor. The rain sensor was not activated, but connected.
