Asked by CuriousInColorado October 8, 2020

can this unit be hard wired installed? in other words, not connected with the a/c transformer?

Asked by Doug September 8, 2020

Yes, it’s 24 V ac and you have to have a transformer to convert 110 to 24v...unless you have a 24v coming in like a doorbell then no transformer would be needed

This was a great improvement over the 10-year old Rain Bird "smart" irrigation controller which had an Irritrol rain / humidity / temperature / weather controller added on by our city. If you take the time to properly configure it, the Rachio R3 Smart Sprinkler Controller is: 1. MUCH easier to set up, monitor and use... ESPECIALLY for occasional manual watering. No more bending down in the bushes to try to figure out how to make our Rain Bird do a "one time" run one of the zones for a specific period of time. 2. SIGNIFICANTLY more water efficient since each zone has it's OWN watering schedule... each zone changing it's watering FREQUENCY and RUN TIME *** AUTOMATICALLY *** depending on the weather. BRILLIANT 3. MORE information on past run times... and future watering schedules for EACH zone all esily available on your iPhone, iPad, or computer. Honestly I should have bought and installed our Rachio R3 irrigation controller when they first came out... Especially since SoCal WaterSmart gave us a REBATE for our ENTIRE purchase price. It only took my wife and I about 2 hours to remove our "vintage" Rain Bird controller, connect our Rachio R3, and go through the entire setup on my iPad. This included time to take pictures of EACH Zone for easy reference (much better than Zone names or numbers), draw the landscape area of EACH Zone on their Google Maps satellite view of our property, select the soil + plants/grass + leval/slope of EACH Zone. 100% worth it since this will save us $$$ on our water bill... and actually make our yard look better too!

Initial setup was difficult because the product would not connect to wifi using the app. Rachio support was able to get the device updated using a file that had to be run from a PC or Mac. After the device was updated it connected fine. Setup is as easy or as detailed as you want. You can select zones, grass type, soil type, and even draw the zone area on a map to figure approximate square footage. There are several schedule types you can choose from and it is smart enough to not water if it has been raining or will rain soon. Overall a great product that I would have given 5 stars if it worked out of the box without an additional update.

Beat Controller I have owned
By far the best controller I have owned. Its technology allows for smarter watering, it works with google assistant, has an app to control all the scheduling and functions. Extremely easy to install. Definitely recommend spending the extra money.

4.9 stars, but really 5
Super easy installation -so long as you know your wiring amd which colors/wires go to what zones in your yard. Fortunately I did, so install did take under 30m as advertised, including install of outdoor enclosure. However setting up of the zones in the app took a bit longer, though still super easy. Loved that the app determines best watering times and durations and auto adjusts to the weather.

A sprinkler system that’s caught up with current tech... finally!
This controller is spectacular. It’s a breeze to install, it has built in flexibility for watering days (e.g. skipping rainy and windy days), and it just looks great. Connecting the wires for each zone was simple, Rachio made it easy to plug them into the respective zone on the controller. It’s a simple easy plug system that you slide up on a lever, insert the wire, and then let go of the lever and it’s locked in. The step by step walk through is awesome as well. They walk you through the steps of swapping out your old one with the new one, and then they have a detailed walk through for configuring your controller and the zones. Once configured, the active zone will glow a blue color as its watering. Neat! Another couple of handy features were zone pictures and Internet connectivity. You can snap pictures to represent your different zones. This allowed us to be able to quickly identify which zone is which. You can also start and stop your system from your phone, which is very useful! Overall, I highly recommend this system for your home lawn watering needs. It was a simple installation, it’s pretty to look at, and it’s extremely flexible with how you want to configure it.

Great Fathers day gift, better yet with HD's veterans discount. The unit is great. Easy to setup and to migrate from my old controller. The App is intuitive and has many features for you to customize for your lawn. Live in an area with water restrictions. Set the specified dates. The unit calculated my zone run times of 24 minutes each. You can adjust if you dont agree. The Rachio3 determined it would be best to split the run times in half and make two passes of 12 minute each. It aslo calculated the start time to finish by sunrise. Wife loves that she can also control it by voice commands. Still haven't finished playing with all the options. Worth it!

I used to love my Rachio, but the current software has bugs. My system will only water on every 3rd day now, no matter what you do to the schedule. It isn't a "rain skip" or "seasonal adjustment". It was 98 degrees yesterday and the same today and it is requires me to manually run the sprinklers! What's worse, Rachio support isn't available. Maybe it's because others are having the same problem and overwhelming their support center, but try it for yourself if you don't believe me. You sit on the phone for a long time before the system finally tells you that no one is available and asks you to leave a message. When I finally got through to someone, they couldn't figure out the problem. I asked for it to be escalated to a 2nd level support which they agreed to do. They said I'd get a call back within 48 hours but "probably would be the same day". It's been over a week and nobody has called. I called them yet again today and asked to speak with a manager. They say they can't do that and can't transfer calls. The ticket had been placed in a "normal" status and that's why nobody called. They said they'd changed that now to "Urgent" but that put's be back at the bottom of the "urgent" queue and no ETA for a call can be given. In the end, the system is buggy. There are severe limitations in the Android application, web site and scheduling system. The system does not water as it is supposed to and the company is unable to back it up. I would NOT recommend this brand again! Buyer beware!

Hi Brian,

Thank you so much for sharing your story. I'm so sorry for the frustration you've experienced with the software and our support team. I'm going to check into your ticket and make sure it gets escalated immediately. This sounds like strange bug but might be an easy fix. Expect a response right away tomorrow morning.

Exactly what I was looking for! I think this will pay for itself in no time. I replaced an old Toro controller that was really difficult to program with the Rachio 3 (R3). Here in North Texas, due to our clay loam soil that needs time to absorb the water you apply, it is recommended that you sprinkle a zone for 3-5 mins, let it absorb for 30 minutes, then 3-5 minutes again, etc for at least 3 cycles for a total of 9-15 minutes for each zone. I have six zones with my system. Not only does the R3 allow me to do that type of detailed programming, but I can also program differently based on my two zones that are shrubs only. The truly awesome feature is the Weather Intelligence (WI) which makes it absolutely worth buying the R3. You can select a type of programming using the WI that will override your programmed schedule in the event of rain that will increase the saturation of the ground in your zones. The WI estimates the amount of water already in the ground, then calculates, based on WI, how fast that water is dissipating. It rained this morning and when I went to check my R3 schedule, not only did it record the approximate precipitation in my area, but it changed the watering schedule accordingly. No local or roof mounted sensor is does it all from official weather data, both actual (after the fact) and forecast data. I also incorporated our local water restriction days into the program so it only waters on Sunday and Thursday (the allowed days for my part of town) for when water restrictions will be implemented. Although the system has not turned on much due to all the rain we have had, I love the fine tuning that the R3 allows. Not only am I not wasting water, but I am improving my lawn with the multiple short cycles that forces the grass to grow deeper and therefore healthier roots. You do need a good wifi signal wherever you are going to install this. But I was also surprised that I did not need a wifi extender for the connected easily even though my router is at the opposite extreme part of the house. I did require the assistance of the Rachio Customer Support staff to figure out how to do all the programming that I wanted to do, but for the most part, they were very helpful and I am a very satisfied customer so far. I can truly now "set it and forget it" and even check up on what is going on when I am on travel through the wifi connection. I have owned my R3 for less than one month, so perhaps I will update this review in a year and let you know how it has performed.

Rachio 3 (16-zones) is an outstanding sprinkler controller. Replaced +20year old sprinkle controller. For me challenge relocating from outdoor to within garage; establishing new outdoor weatherproof electrical box-receptacle. Home Depot On-line purchased, shipped free, UPS arrived on-time good shape. Rachio company provides free recycling old controller unit, but uses FedEx; work w/ Rachio Support getting return FedEx shipping label. Recommend installing Rachio 3 "Smart home system": easy connectivity to NOAA weather predictions controlling sprinkling accurately and allowing my cellphone intervening when needed, I now fine-tuning watering of each separate zone.
