Review: Excellent product, but not for everyone - 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
Review: Vital part of a smarthome setup - Where do I start? If you have a smart home integration setup -get this. If you want to save water - get this. If you want frustration free irrigation - get this. If you want a rebate - get this. So take $99.00 off from the price if you live in Central Texas because there's a rebate by LCRA, that's right just for purchasing and installing this product you get a $99 check from LCRA. Nothing to send in, just go to their website and fill out a form. This sprinkler system uses super accurate weather forecasts to determine rain hold days. You can set it up to be dynamic based on soil conditions or program a static schedule. You can start your sprinklers from your phone - from another state if you want. Tracks water usage, schedules, rain hold days and you can add other people from your household to your account so they can control it also. If you are like most people out there, your rain sensor doesn't work anyway. Ever run to the controller when it's raining to shut the sprinklers off? I have, I don't anymore, this thing is smart enough to activate rain hold based on the forecast. The forecast could be wrong you say.... well this is not your average forecast. The weather is provided from a network of 300,000 weather stations and other sources to provide hyper-local weather forecasts. It's never wrong. Installation: takes about 10 mins 5 mins to remove the old one 5 mins to install this one. It will take you another 10 mins to setup zones where you tell the application what type of irrigation, vegetation and soil composition you have. You can actually take pictures of your actual zones to put into the app. (see pic above). You can set it to notify you when zones start and stop, or tell it to leave you alone and just do it's thing. I have it integrated with Home Assist - An open source home automation server that ties my Alexa, smart-things, cameras, nest, august locks, network devices and now my lawn sprinkler system together. You can even tell Alexa - "water backyard" and presto - your sprinklers start running. The wiring is so easy a caveman could do it - M=Master pump, +/- 24volt power and one wire for each zone. I even used the screws that were in my old control panel. If you're on the fence about this purchase, pull the trigger. It will save you time, money and frustration over time and pay for itself. I can not speak to the durability of the product, however since you never actually touch the controller to operate, I suspect that it will last a long time. I would recommend this product 100% without reservation and they make an 8 and 16 zone version. I am reviewing the 8 zone version, however the 16 has all the same features. No jinky setups, everything was straight forward and easy, the software (phone app) is really intuitive and makes it easy to schedule and manually water. It will take care of the lawn for you. Set it, and forget it. No more running to shut off the sprinklers in the rain, no more brown grass because you forgot to set the schedule to run.

## Questions & Answers

**Q: I have a zone that is under cover and never gets rain. Does the Rachio 3 allow for one zone to run regardless of rain while other zones don't?**
A: Despite the answers above, the answer is YES. You can create a separate schedule just for the zone you desire and make it a fixed schedule. You can turn off all the features and that will make it run even if it’s raining or windy or whatever. Than create schedules for the rest of the zones with all the weather features you like.

**Q: Does this have a setting for a delay between zones? The controller i'm replacing does not have this delay,it switches between zones fast, hammers pipe**
A: Yes, at least with my gen 3, a feature to reduce water hammer will turn on the next zone 10 seconds early allowing no abrupt stop at the end of a zone run.

Excerpt from Rachio help:

What is Rachio's "Minimize Water Hammer" setting?
With this setting, your Rachio Smart Sprinkler Controller will open the 'next' scheduled zone to run in a watering schedule, 10 seconds prior to the end time of the current zone that is running.

**Q: Can it be hard wired from the modem/router with cat5 or 6? no wifi where it would be installed. does it have an ethernet data port?**
A: No data port — BUT, it works on both 2.4 and 5Ghz bands of wifi. Works very well and connected very easily. Access point is through a wall about 25 feet away.

**Q: Can each valve be set up as it's own zone with independent start times and durations?**
A: You have to understand that each zone needs to have it’s own solenoid in order to control zones separately.  Some homes use an index valve system, and you switch zones by turning off and on, and the water pressure turns the index valve to the next zone. That won’t work with Rachio or any of these kind of systems. You will need to remove the index valve, and rearrange each of the pvc pipes that connected to it. That can be accomplished with a days effort, but you’ll need pvc fittings, a pvc cutter and pvc cement, and a solenoid for each zone you have. Each solenoid has two wires, so you’ll also need  sprinkler cable with two conductors for each zone. So for a 5 zone system, your cable needs 10 conductors.

### ⭐⭐⭐⭐⭐ Fantastic for many reasons
*by J***C on August 1, 2026*

Absolutely fantastic system. Easy to program and make adjustments via an app on your phone. This works great if you are away from your home and wish to make a change in schedule, duration, etc. What I also love, and any one who does their own sprinkler system repairs will love, is that you can turn your system on and off while being at the site of the repair versus having to have some one else manage the on/off or risk losing a lot more water while you run to see the leak and then run back to turn off the system. Also easy to install and operate.
