Intelligent watering
Purchased several months ago, it works beautiful. Simple to program and saves a ton of water. Check my lawn, flowers and vegetables, with a moisture meter, all good based on weather and evaporation. Highly recommend The app is GREAT

    The ease of installation (followed instructions and there were no hitches or surprises). The ability to manage all from my phone makes this unit great! I paired it with a rain sensor and the system works perfectly. The only part I could have a slightly irritated comment about would be Home Depot and its shipping to stores. They are slow about moving product to you. Other than that I would highly recommend this unit to anyone who is upgrading. An added bonus for my area is that the City Water Division is offering to rebates on upgrades like this. So after all is said and done I ended up getting back 80% of what I spent for the until and the rain sensor!

    Wonderful all around- great features unlike any competitor. Attractive
    Works perfect. I have 8 zones for water, 1 for kavk forty trees 1 for misters. Two for sessonal drips to hanging baskets and porch and deck plants. For lights. I have it hooked up to alexa. On a hot day i can activate anything. I have it hooked to three weather sources. NOAA, Dark Sky and a local weather undergoeound. It averages them for predications. It also updates past rain predictions with actual rain every 4 hours. Then it adjusts watering based on actusla. If the internet is down it uses last ten years history. It also has another fail safe to water the same as last day. I never have had one failure. It has software api that rocks. It has full local ip connection control or world wide web control if you choose. Full logging of eventes and os errors. Only down side is it only has wifi dobgle and no hard wired ethernet. But that was well documented. It also has an un-needed method for rain detextion. Pretty lame. Last it can run a pump or that circuit could be used to have a master valve before your entire system to assure a system failure is limited. With the api you could even monitor excess water from base line and send notices but that would be up to you to program, however, it is super cool that you can mist system dont even give you that option. On notices it sends text messages for everything. I have it send one for shorted valves and freeze condition. It also graphs last 30 days and last years use. I extended the location 50 feet just so I could have it in the house to see the weather forcast and easily access the sweet touch screen. It has a responsive touch screen with all the cobtrol the phobe offers. Buy it if you are a pro or want full control. Or if you just want to water at fixed times and durations then you can do just thst and build from there as you are comfortable. Either way you are set. I programed mine from my iphone and also from the control pad. Both worked well. The phone has features the panel does not have but nothing that required me to have to use both. The control pad has feature the phobe does not have but again those are related to how you want the control pad to display stuff like, sleep, brightness wtc. and its os stuff.

      As described. Easy install and setup. Minimal space required. Adjusts watering schedule based on weather but can easily override or on demand/manually water areas/zones as needed. Within app you can add pictures to the zones to easily identify areas. Can access and program by smartphone or computer. Once installed no need to physically access unit. Makes watering fun.

      The hardware is good. Sometimes the app takes too long to load or needs to reload itself to work. Only get this if you are willing to invest the time it takes to program the app to automatically water the plants. (it took me about 30 minutes to do the 6 zones in my yard, but it's capable of doing 8) If you run the program manually, it won't save water on cold or rainy days. You should program it to start automatically at certain times, then it will use the weather data to save water. Mine wasn't accessing the NOAA website correctly (the software thought that the min. temperature each day was zero degrees,) so i easily added another weather service, now it's working better. Sloppy app programming but easy workaround. If you want a better app and either have more zones or want to spend the extra money, try the one by Rachio.

      What can I say? I'm just simply blown away by this tiny sprinkler controller. It's certainly very clean aesthetically speaking and installment was a breeze, virtually tooless with the exception of the 2 screws to mount to my sprinkler box. Setup was a breeze, I'm a network admin by trade and can honestly say a non techie person can set this up in their WiFi network. From open box to full programming took me less than 15 minutes. The cool camera feature allows you to take pictures of your zones that are active making for impressionable conversations. I origonallo bought the Orbit B-hyve and it was huge it wouldn't fit in my sprinkler controller box and then I read about this Rainmachine with a bit of skepticism and apprehension because of never hearing about this brand, but I'm totally sold on this idea gong forward. It totally makes sense that a controller box is simply that a small circuit board, no need for a monster size box. The only improvement I would recommend for Rainmachines next model is for a better outdoor box with weatherstripping, we live in the high desert and it gets cold. Other than that phenomenal piece of engineering!

        We love being able to adjust the sprinklers from our phone. We just reseeded some of the backyard and its very easy to adjust/add additional time depending on the weather to keep the new seeds moist. Would definitely recommend this controller

        Stop looking and get this one. This is the only Smart Sprinkler Controller I could find that is cloud independent--no fees, and will still work without an internet connection. It is not reliant on Rainmachine's cloud service. Hookup is very simple for up to 12 stations. Use either or both common wire connection points. Works with existing rain delay. TFT touch screen is all you need to get going and program. Use a smartphone or any internet connected device to dive deeper into the settings for better water control. Access, adjust, and change water setting from anywhere. Uses NOAA, or choices of other weather stations to automatically adjust watering. Total time for install and programming is about 15 minutes. Internet connectivity is very automated and has very strong signal even for a large home. PROS 1) Not cloud-based. No subscription charges. Will work as a standalone. 2) Super easy installation and setup. Integrates with any sprinkler system. 3) Access and adjust programming from your laptop, tablet, or anywhere. Lot's of adjustability. 4) Intuitive instructions. Easy to use large TFT (touch screen). CONS 1) You pay for what you get, and this system is a bit more than others. 2) So simple to set up, smart guys will overthink it a bit and wonder what steps they missed. You didn't miss any, it's just that simple. 3) This is nitpicking: You can't set the "soak" feature independently for each station--it's either all or none. Since Rainmaker updates their firmware from time to time, they may change the soak feature to be accessed independently for each station.

          Watering your lawn made easier
          To start this is a very compact and minimalist unit. It was extremely easy to install, it had good instructions on how to wire it and I like that instead of having to screw wires in all you had to do was strip the ends of them and the push down a small spring loaded button and then simply insert the bare section of wire and release the button. Then when it comes to programing it you download the app to your phone where you can program it or you can use your computer and go online to program it. There are a lot of options and it may seem a little intimidating at first but once you start to use the program you realize how easy it is to use making it very easy to, program, adjust and operate things. The app works excellent and so does the online site you can use on your computer to program it. I started with the same base times I have always run my sprinkler zones on and I have already noticed it working according to the weather where it has canceled watering on days where it has rained a lot. I also like that your not tethered to a third party cloud service so there is never a fee to pay and your not dependent on single system. The WiFi on it works excellent and it is cool that you can access it thru an app on your phone or online on a computer anywhere or anytime. I have already got it programmed very easily and seems to be working very well and I will be interested to how well it works over the summer and I will update my review after I have used it a couple of months. As for now I have rated it 5 stars because it was super easy to wire and install, programming it thru your phone using the app or using the website on you computer is very straight forward and easy, and your not tied to a 3rd party cloud based service that you have to pay for.

          love this Rain Machine smart sprinkler controller!! amazing!
          I absolutely love this smart sprinkler controller! This controller is a life saver, lawn saver, and time saver! We recently reseeded our front lawn as it had become a bit patchy and weeds have invaded after last's year drought and watering restriction in California. With our old controller, watering everyday felt like a huge burden, since we had to do it manually. However, this smart sprinkler controller has completely changed lawn watering. The product is absolutely flawless. It is very easy to install, it took me no more than 5 minutes to put it on the wall and plug the wires, and a total of maximum 15 minutes to install the app and do the configuration. The controller itself is so simple, compact, and easy to install. The smart phone application works on both Android and iPhone. The app also is amazing, super simple to use and it never crashes. Besides that, it uses weather data to adjust watering. All in all, this smart sprinkler controller is super convenient and easy to use. Highly recommend to anyone, it is an amazing product!
