## Overview

The Rachio 3 Smart Sprinkler Controller is a 16-zone, Wi-Fi enabled irrigation system that leverages hyperlocal Weather Intelligence Plus to optimize watering schedules.

It automatically skips watering during rain, freeze, or wind events, helping reduce water waste and lower bills while maintaining a healthy lawn.

## Description

The Rachio 3 Smart Sprinkler Controller raises the smart watering bar with foolproof installation, dual-band Wi-Fi and an expressive light bar. Rachio 3 is the only controller equipped with hyperlocal Weather Intelligence Plus. The Rachio 3 Smart Sprinkler Controller automatically creates watering schedules that lower your water bill and ensure a beautiful yard, while the mobile app lets you manage your sprinkler system from anywhere. Rachio partners with the top smart-home platforms including desertcart Alexa, the Google Assistant, Nest, IFTTT – making it the most connected controller on the market. App Compatibility - Android 4.4+; subject to change. Mobile app is required to connect the controller to Wi-Fi. Systems that source water from a well will likely need a pump to add pressure for sprinklers.

Review: Looked at upgrading my current RainBird ESP-ME controller to WiFi capability. When I contacted RainBird, the LNK2wifi module would not work with ESP-ME before Nov 2016. So I looked at getting the ESP-ME3. Well, you can get it but then you still have to buy the LNK2wifi module - it doesn't come with it!!! So I looked around and so glad I found Rachio 3!!! As advertised, I was connected in 15 minutes!!! Cavet, 2 of 3 mounting holes fit from the old system and I had already labeled my station wires from the last time I dinked around with the old controller. So just putting in third mounting hole and connecting the wires was a breeze. Downloaded the APP and it was pretty straightforward to set up the zones, take pictures of my zones, etc. With push of a button my zones were active. Seamless integration! All for MUCH LESS than what RainBird would have cost!! The only issue was connecting my Hydro Rain HRC-100 sensor. It actually was bad either but there was some conflicting discussion on the Rachio forum. The Rachio controller already has connections ready for the sensor like this. Still quite not working but that is due to the HRC-100 transmitter - batteries died. I like the fact the Rachio APP looks at local forecasts to monitor whether it is going to rain or not. The one dig is Rachio wants to charge an additional $30.00 for their valve sensoring diagnostics. Debating whether it's worth it or not. In any case, the Rachio 3 definitely was what I was looking for to control my sprinkler system when not home. It is at a good price. Easy to install and get going. I do agree with another reviewer in that the controller LED should cycle back 'n forth like the Ceylon bots from BattleStar Galactica. That would have been so cool.
Review: 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 desertcart 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.

## 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.

This controller is a great replacement for my old Rainbird 16-zone. I really like being able to use my phone or alexa to turn-on zone 13 for 10 minutes while i'm in the back yard with the root feeder staked in the ground.. Makes for quick watering without having to walk the 1/2 acre back and forth 18 times. I was also able to connect my old wireless rain/freeze sensor.
