Rachio WiFi Smart Sprinkler Controller (16-Zone Irrigation Remote Control) – App-Based Scheduling, Local Weather Intelligence, Rain Skips, Easy DIY Install

I debated for a long time before purchasing this product due to the mix of very strong reviews — both positive and negative. After using this unit for about 2 weeks, and experiencing a lot of weather in the North TX area, I’m writing to speak to both sides and offer my observations in hopes that it will help others who find themselves in the same dilemma that I did. First, let me say that this is an awesome product. Having worked in technology, and specifically software engineering and product development for 15-20 years, I truly appreciate the simplicity of the product. The entire setup process — from opening the box to having water running in our yard — lasted maybe 10-15 minutes max, and it was only that high because I spent about 5 minutes creating a label on our label maker to “mark” the zones on the outside of the unit. Some might call this overkill… my wife calls it particular… but nevertheless. Everything from the design, to engineering, to the magnetic cover, the software in the app (we use iOS)… it was simple and the experience was like opening an Apple product and having it “just work”. Second, let me speak to the setup options, since I think this is where most folks that write negative reviews get hung up. There are basically two paths to choose from, and there doesn’t really seem to be a middle ground. One path is to basically set it up as a “dumb controller” — meaning, think of what your parents probably had 20-30 years ago in their garage. You set a schedule, it is fixed, and it basically runs on certain days and times that you set. If this is your preference, then save your money and buy a different controller. There are way cheaper options on the market, and this product is going to be overkill for a schedule that simple. The other option, which is why I suspect most of you are probably interested or reading this in the first place, is what this system is really designed to do. You can set it up as a “smart controller” — meaning, you set a base schedule, along with some data points specific to your location, and these are fed into an algorithm, along with real-time weather information from your area, and it basically adjusts “on demand”. For example, if it rained more than a certain amount (you can set the threshold), or if rain is even expected in your area in the next 24 hours, it will skip a cycle. Or if it detects winds (again, you can set a threshold), it might adjust the time. Same thing for temperature below freezing, soil moisture, etc. There are a lot of options and you can customize which ones per zone… for example, one of our zones is a dedicated drip hose, so the wind alert doesn’t really matter but the soil moisture does. The neat thing is you can set multiple “schedules” and target different settings for each. The only thing to be aware of, is one of the settings is “time of day”… so if you have multiple schedules for the same day, and they are both set to “finish before sunrise”, for example, you might run into weird situations. We get around this by alternating days (or you can set a “fixed” time of day for one). Just a heads up for anyone running more complex schedules across zones. The “smart controller” setup (as I call it) is a little more work up front, and if you do it wrong, I can totally see how it will mess up your yard. However, it’s not all that difficult, and once it’s setup as intended, it’s totally worth the money. Based on our water usage, and the unpredictability of weather in the North TX area, I think this unit will pay for itself in a matter of a couple months. In the past 14 days alone, it has already saved us from running 4 different cycles for who knows how many hundreds of gallons each time. Again, this means that you actually have to do some work up front to make sure it is setup correctly. It does require a little bit of knowledge of your soil type and the ability not to over-estimate slopes. For example, just because your yard is graded (to get water away from your house) does not mean that the slope is “extreme”. All of the factors go into the algorithm… so if you get it wrong, that is not Rachio’s fault, even though it sounds like that is where most of the negative reviews stem from. It’s just like anything else with data… garbage in = garbage out. If you put good data in, then the results can be remarkable. The only downside, if there was one, is I could not get this to work with our existing rain sensor or HomeKit. The rain sensor threw false positives, and once I figured that out (thanks to Rachio alerting us "why" the system did not run), I just unplugged it and it's one less thing to have to worry about. For HomeKit, with a background in software engineering, I’ve looked into this technically and this appears to be an issue with Apple’s integration rather than Rachio. Practically, all this means is I cannot say “Hey Siri, turn on our sprinklers for 10 minutes". Would that be impressive to show off? Absolutely. But with the intelligence already built into Rachio's software, there’s a good chance I’ll never need to do anything manually ever again. In summary… this is an excellent product, but it is not for everyone. I do wish there was a review like this a few weeks back so I did not have to spend time second guessing myself before we purchased this product. All in all, this is a solid product, and I would highly recommend it… as long as you have some time to set it up correctly. I hope this helps! Justin

This sprinkler controller has been incredibly convenient and simple to use. The app makes it easy to control everything right from your phone, whether you’re at home or away. Scheduling is straightforward, and I love being able to adjust zones quickly without any hassle. Setup was easy, and it’s been reliable ever since. A great upgrade from a traditional system—highly recommend if you want something efficient and user-friendly!

This irrigation controller is perfect for homeowners who have 8 or less zones to their irrigation system. If you have basic level knowledge of tools and how to do simple home improvement tasks, installation is very easy. A perfect replacement for old school controllers (like my old Rainbird model with a dial and simple numerical screen) that were annoyingly complex to try to control schedules, do seasonal or rain adjustments, or just manage in general. These are often on sale during big Amazon sales events, so I picked it up for quite a discount during Black Friday / Cyber Monday sales. - Installation consisted of unplugging the old Rainbird controller, carefully labeling each zone (1, 2, 3, etc.) and the common wire as it was installed before, disconnecting all labeled wires, and then removing the old controller from the wall. New install was pretty much the reverse. Took approximately 30 min at a leisurely pace. - Initial Setup: Super easy via the app and only need to setup a Raachio account, and of course needed my WiFi password to connect the controller to the network. - The app: Very intuitive and easy to use. I love that I can take a picture for each zone so I know what is what. I can use the app to quick run each zone while I'm walking around to inspect sprinkler heads and make adjustments. No more running back and forth to the controller on the wall. Schedule setup was very easy and it is easy to have multiple schedules with any combination of zones assigned to each schedule. For example, I have one schedule to run my yard zones, and a separate one for my raised garden beds using drip lines. The system uses local weather reporting to perform "rain skips" based on predicted or actual precipitation. The rain skip is really the only drawback I have found so far. When summer temps are really high (95+ deg) it is not uncommon where I live to have inaccurate rain predictions due to small thunderstorm cells that may rain close by but not at my location. Sometimes the system will rain skip a schedule based on the weather prediction, but in reality no rain was received. I end up having to manually un-skip the rain skip occasionally. However this is only a minor issue and still miles ahead overall compared to the old outdated controllers. This also could be a function of the type of schedule I set up; there is a much higher level of customization available than I have fully utilized.

Finally figured out annoying zone Fault error for master valve operation when multiple master valve connected to the M terminal along with the regular zones Operation for about less than $20 wiring work, Really simple wiring and thanks to amazon for selling such simple devices to help rescue in this matter. It’s shame that rachio engineers didn’t design enough power for each channel especially when there is M terminal available for use. Customer should not need to buy anything else to make it work all together. At least they should have allowed up to 5 Amps of power usage for simultaneous multiple zones operations and multiple master valve operation. Which is very common these days. Anyways. I highly recommend, using individual master valves for front and back if you have multiple pipes feeding irrigation at your home, to save on leaks, and protect your irrigation and extend valve life using these available master valve terminals on Rachio 3. It is very simple, to wire up. I got all links for the product and wiring diagram shown below that has been tested and work prefectly. This is all you need. I have got 2 Master valves (1 for front yard, 1 for back yard), hooked up to external power source of 24VAC plugin type, using this simple DIN mount $10 24vac contactor, https://amzn.to/46q988x And this power supply, 24VAC, https://amzn.to/3I0UI6B wired externally to power up these master valve it works flawlessly, I am using these master valves https://amzn.to/4mck5QJ which shows 5W power consumption which is great for the application, however always have higher rated power supply purchased, to be safe to handle inrush (higher current for start up) current of valves when they open initially. I was able to simplify the circuit and use these externally powered master valve with any zones without any zone fault error or compatibility issues with Rachio 3. The product I shared above have been tested by myself, and I guarantee it works as long as you wire them correctly. if you have any questions then please let me know. If you use my link to purchase, it would tremendously help me provide support for your need, feel free to text me here if you have any questions. Hopefully, these photos with wiring diagram helps you out. If not just shoot me question here. The wiring for external pump would be very similar, but I can help you with that if you have unique situations for your case. Just ping me here and be happy to prepare your circuit diagram.

6 years in and it’s still working fabulously. I’m sure it’s paid for itself in water savings several times over. This is the second unit I’ve owned and the first one is still in use at the home I sold in Colorado, as far as I know. It takes the guesswork out of watering schedules and adjusts automatically based on the actual weather from nearby stations. It’s been completely hands-off and trouble-free.

Wow. Install was super easy. One hour. Walked around the house and it turned on and off each zone with a button click. Everything works. I just had sod placed on three section of my yard. Programming to water new sod in n the took two minutes. And it compensates for rain and knows how to handle new gras. Wow.

This was my first experience with a Rachio sprinkler controller. Installing the unit was quick and easy. Linking the unit to the App and setting up the system was not. I eventually had to reset and start over the set up process several times. However, once that process was completed, things have been working just fine without any issues. I really appreciate the ability to control my system from my phone and I especially appreciate the extra features like weather tracking and automatic adjustments that come with the unit. I was a little disappointed to see that I had to pay extra in the app to take advantage of all the features that the unit offers, I’m not a fan of “pay to play.” This includes features like sprinkler valve monitoring to alert you of potential problems in your system. If the unit has that capability, then just include it in the initial cost of the product. That said, in my opinion the pros do outweigh the cons and I am happy with my purchase and do recommend it for others looking for a sprinkler valve controller with internet and app capabilities.

High-quality product with helpful features. The timing setup for regular programming is easy to do. Scheduling one-time watering cycles was not an issue. I’m not sure how they measure the moisture of the soil for each setting but they do show it and it works as many minutes as you wish. The installation of the controller can be a little challenging but read the directions carefully. I strongly recommend this purchase for your home lawn and garden. Our local water company covered $150 of the purchase price which was a nice surprise. Do yourself a favor and buy it today and you will glad you made the investment.

Very easy to use, a lot of modofications available, really good device. The only problem if you don't have US socket, but you can solve it using another adaptor.

Unusable device in UAE based on our power standards. Avoid!!

It's only been two weeks but I will give you my first impression and it's a good one. The reason I was looking for a new controller was my old Rainbird always had issues with connecting to my wifi. It was ok feature wise but felt it was falling short. This new Rachio was super easy to install. I loved that fact the bottom of the control was left open so you don't have to pull wires through any holes. Face is held on with magnets, another nice feature. Connecting wise, Are you kidding me! I blinked and I missed it. I thought for sure I did something wrong as it should not be this easy but no! I was wrong and it was connected and it really was that fast! The rest of the set up was just as easy. I'm a guy, who has time for instructions, not me!!!! And you truly do not need them. It walks you through everything step by step. I found everything easy to understand and to navigate through. It has some great features in my opinion zone wise. Asks about your area you live, asks what kind of watering you are doing (Grass, bushes etc) what type of irrigation heads you are using. What slope the area is on. It then gives you the option to name the zone and add a picture. All this is to optimise your watering. So cool! Timer wise, again super easy. I asked to end my watering cycles at sunrise and it figured out the start times. Because you entered all the information about the zone it automatically calculates how long each zone waters for. Keeping in mind you have full control over all of these settings if you wish. It watches your local forecast and it has only watered once so far. Its early spring here and it has been cloudy and sometimes raining. It is pausing my schedule automatically for me. Such A nice feature. I was a little hesitant on giving it full control but since you can easily go into the app and monitor your past watering cycles I feel comfortable knowing I can monitor it and see what is going on. Another very cool feature. It's not the cheapest unit on the market but due to all the features, the care free operation it's worth every penny. For anyone that has never used an App based watering system its pretty cool. My cell phone notified me someone was in my yard (Security camera system). When I looked someone was walking their HUGE wolf dog and it decided it didn't want to go any farther and layed down on my lawn. She was pulling and pulling. No way she was moving him. So I decided to help her out..... I opened up my Rachio app and flicked the zone on. Wanna see how fast a Wolf dog can move!!!! She literally said out loud laughing. THANK YOU WHOEVER YOU ARE !!!!! LOL!

Muy buen servicio, entrega muy rápido, buen precio

Great unit, easy to set up and works well. For those in Australia, if you buy from the AU Amazon site the package includes 240v Australian transformer which is nice.
