Sometimes things are just easier without your smart phone. Maybe your phone is charging upstairs and you just want to quickly adjust the sprinklers before you forget. On Rachio, that’s difficult since the controls are under the cover, with just a few buttons available. Skydrop has controls, but it’s also a little difficult to use since it requires a spinning dial.

RainMachine wins this one for their illuminated touch keys and HD touchscreen that makes it easy to schedule either on the device or on your phone.

        I have been looking at all the features with the Rachio and Rainmachine. I do have a problem with not being able to manually do changes from the box with Rachio . I need 12 zones Rachio has 8 or 16 . I agree with your review so I have decided to go with the Rainmachine. Thanks

        Hi RB, I recently talked with some of Skydrop’s staff, and they typically do not charge a $6 a month fee. They sell their system through partners and bundles who may sell Skydrop at a much lower price and then charge a fee. But for DIY set up (which most of our readers use), there is no fee whatsoever.

        1. D. Anderson

          Hi Alysa. Thanks for all the great information! But just FYI – there are customers now being charged $6 per month for the app who purchased their SkyDrop at Lowe’s (per their reviews on lowes.com). That’s as “DIY” as it gets, in my opinion. They are charged after a free “trial period”, so then it’s too late to return the product. I am currently awaiting written confirmation from SkyDrop that I will NOT be charged (before I install, because I will return it if there is a monthly app fee). Just wanted to let you know, since there seems to be a lot of conflicting info “out there” on this subject.

          1. Alysa Kleinman

            Thank you very much for your comment! As you said, there is a LOT of conflicting info out there. I’m reaching out to Skydrop for further clarification of exactly when their $6 monthly fee is required. I will fully reply to your comment and update this blog with more details by next week. Thanks again!

          2. Alysa Kleinman

            Hi there, I wanted to reply one more time now that I’ve followed up with Skydrop. They reiterated that anyone purchasing from a retail location should never be required to pay a monthly fee for the app. While I see the $6/month information in some of the reviews on Lowes.com, Skydrop has made it very clear to me that this monthly fee isn’t applicable for retail, self-installed options. For any questions about specific cases, they encouraged me to have you contact sales@skydrop.com.

            While you might not be keen to reach out to their sales team, they were actually very helpful for me in answering these questions and will definitely help clear up any misinformation that you’ve heard. Thank you again for your comment!

    The Rachio seems to be the only one with an optional waterproof enclosure for outdoor installation. The other two seem to be for indoor installation only. My old unit is outdoors so that is an important differentiating factor. Going to get the Rachio.

    1. Alysa Kleinman

      Thanks for letting me know! I actually found waterproof enclosures for all 3 devices, although RainMachine can be temperamental outdoors since it has a touchscreen. I added details and links to the blog post, but I’d probably agree with you and recommend Rachio if you need to install outdoors. Thank you again for the comment!

    1. Alysa Kleinman

      Hi Howd, thank you for your comment. I checked with Rachio and they informed me that the Rachio controllers are manufactured in the U.S., but the included power adapters are made in China. This may be where the confusion is coming from, but the device itself is made in America. Thanks!

  2. andrew

    In my view Rainmachine seems to have an easier interface. “easy to use’. And has much better historical graphs — the relation in between weather and water use is well defined.

    Rachio is a good controller has nice outdoor enclosure for the ones that need to place the controller outside for both 8 or 16 valves options.

    Skydrop looks flashy, but I doubt the usefulness of the interface. A jog-dial? How do you type on it? Why not touch screen? If the $6/mo fee is true, nobody will buy it.

  3. Smart Home Solver

    Hi Charles,
    Thanks for your comment. I’m glad that we both picked RainMachine as the overall winners comparing Rachio vs RainMachine. I updated our review to include the details you listed about shade/slope and WUnderground compatibility. Thank you for the corrections!

    Sky drop is now extorting &2 a month for use of their app. For this reason alone you should eliminate them from consideration!

    1. darrell

      Skydrop ran out of money and went out of business, basically. I wouldn’t call it extortion as they are trying to continue to provide service essentially out of their own pockets. They sent the following e-mail to their customers:

      At the end of 2018 and after exhausting all options, Skydrop ownership made the difficult decision to discontinue operations. The immediate concern was for the many loyal customers that would see their smart controllers reduced to being dumb traditional timers when the Skydrop Cloud ceased operating. A few of the passionate (former) employees wanted to find a way to maintain the Skydrop Cloud and determine a path forward so that customers could continue using the devices and services they have enjoyed. The owners agreed to allow us to at least maintain the cloud services and retain a single full-time customer support employee.

      For the last several months, as we have transitioned to positions at new companies, we have volunteered our time and personal resources to keep the cloud services up and available. Of course, this is not a long-term solution. We need to get Skydrop onto reasonable financial footing so it can either be acquired or continue operations with a few full- or part-time employees. Our options were: 1) increase sales (hard to do with no sales or marketing team); 2) ask the existing customers to pay a minimal fee to support the continuing availability of the cloud services or 3) shut down the cloud services immediately.

      We sincerely apologize for this unwelcome news. Our hope is that our customers will see the value in the service and be willing to contribute to the ongoing costs of the system. We’ve also decided to disable, for now, the option to pay the yearly fee with an in-app purchase. We want to avoid the situation where the company accepts money for services they are unable to deliver.
