Is a ground probe that measures moisture in the soil to control whether or not the system runs? Weather forecast info is not reliable as described in some of the questions. I want the system to skip watering if soil is moist.

Beware if you’re in a dry climate
I was very pleased with this product until I wasn’t. I set it up, it watered automatically to get the soil moisture to the right level and then it used the “smart cycle” mi after that. Well, between 2 saturation skips and 5 rain skips it decided it wouldn’t need to water for 7 days in a row while the outdoor temperature averaged 110. This happened to coincide with a vacation of 10 days. It looks like I lost about half of the plants and trees. I won’t know for sure until next spring. Update- the company emailed me back and said the weather source was at fault. The problem is the source is the default, I didn’t choose one. Even more ridiculous, what weather source would decide to skip watering for 7 days in 110 degree weather? They also said I could have used the manual override option. Excuse me? I bought the thing to do less monitoring of my system, not more. Absolutely unacceptable responses.

    Very dissatisfied with Rachio Controller
    I bought this a year ago. I had a number of problems with the first controller and had to have a new one shipped to me. Then when starting it up this year, it completely stopped working again. I contacted support and was told the controller's motherboard was bad and they'd ship a new controller. After a number of attempts to get confirmation of its shipment, I was told it was finally on its way. When it arrived, I had received two controllers. Neither controller worked however. Searching online, it appeared that both the new controllers needed a software update. I contacted support again but received no response. I returned all the controller and bought a BHyve controller in its place, which has worked well.

      Horrible wifi connection
      I bought this last year. Very difficult to get linked to wifi. Today, for some reason it is offline and again, won't connect. I have had no problem connecting garage door openers or my home security system to wifi through apps. This product is pathetic. When it works, it's good. But I've had enough of its poor wifi crap. Rachio needs to get a product engineer like Lift master. I don't recommend this product.

        Great Until it Wasn’t
        Worked great until it didn’t. Completely dead one month after the 2 year warranty was expired.CS told me to kick rocks. I would never do that to a customer in my business, so I expect others to stand behind their work as well. I’ll be finding a better product with better customer service for its replacement.

          I installed that system in the summer and it’s pretty amazing. I like the automatic adjustments for weather which saves me money!!

          NO Manual BACK UP
          I bought a Rachio about a year ago, and it completely stopped working. I spent an unreasonable amount of time troubleshooting with their customer service, only to be sent a used, refurbished older unit as a replacement—which also didn’t work. The second replacement does work but is also CLEARLY a refurbished used one. More importantly…there is no manual way to run the sprinklers if this equipment malfunctions. Other brands don’t have this issue. This product has proven to be unreliable, and their customer service has been frustrating and unhelpful. For the price, I expected dependability, not repeated failures. Definitely not a brand I’d recommend.

            Constant Off Line Status
            This controller would regularly go off line and would cancel any scheduled watering events. We have automatic watering for animals hooked to this controller and would regularly find their water low or empty because this controller’s regular reoccurring off line status. A time suck to update Wi-Fi connection and network, unresponsive buttons on the controller and troubleshooting in the App made it very difficult to work. I would not buy a Rachio product again. The attached photo is the best way to repair this controller.
