Rachio vs RainMachine – Which Smart Sprinkler Should You Buy?

rachio vs rainmachine

Smart technology has entered the irrigation technology just as it has done to the world of phones, security cameras, tablets, microphones, headphones, and so on. Today, we are saying goodbye to the automatic irrigation controller timers, which, although they did a good job, they had a challenge as nobody would be available to adjust the controllers when the weather changed.

During summertime, people struggle to keep their lawns green. But with the fact that droughts are becoming more frequent, it becomes paramount to save on water even as you strive to keep the lawn green. The most significant cause of wasteful watering of lawns is caused by automated watering systems that are not smart, and they do not understand the various weather patterns. Chris Klein, who is the CEO of Rachio, came up with the idea of having a smart sprinkler after seeing the wasteful nature of automated sprinkler systems. The company came up with a product that you can control using a smartphone and can monitor the weather and also allow you to view your usage history.

Rachio is not the only company that offers smart sprinklers. There are other companies, such as RainMachine, that have a reputation for making smart sprinklers that you can trust. In this article, we want to look at smart sprinklers from the two companies and see how they perform and which one you should pick over the other.

Similarities: Rachio and RainMachine

One reason for using smart sprinklers is to reduce water wastage. It will, therefore, be wastage if your sprinkler continues to spray even when it is raining as the automated sprinklers will do. Rachio and RainMachine come with rain sensors that enable them to stop watering while mother nature is doing it herself, thereby helping to prevent water wastage.

Maybe you are wondering, what happens if I have a large garden? Well, worry no more as the smart sprinklers from the two brands offer you an 8-zone model and a 16-zone model so that you can be sure to get a sprinkler that will work for you whether you are watering a small garden or a large piece of land.

When you want to buy a smart sprinkler, it would be a definite plus to get a product that will work with your smart home hub so that you can control it and other smart home devices from one centre. Thus, Rachio and RainMachine work with a variety of smart home hubs, including SmartThings, Nest Hub, and so on.

It would also be an impressive thing if you would have the opportunity to control your device using your voice as much as you have the app control. In that aspect, the two products support the use of voice control assistants such as Amazon Alexa and Google Assistant so that you can control them using your voice.

Being smart devices would mean nothing without connectivity. The two brands support WiFi connectivity over 2.4 GHz 802.11 b/g/n connections. Additionally, you can control the devices using a mobile app that is available for both iOS and Android devices.

The two brands are the top brands in the smart sprinkler world, and as such, their products come with a two-year warranty, which gives you confidence that what you are buying is high quality.

As much as you can control the devices using the Smartphone app, they also come with on-device controls, which allows you to control the devices on the model itself, which is also an impressive addition. 

Let us now look at each device in-depth, its features and specifications so that we can tell them apart.

Differences: Rachio and RainMachine Smart Irrigation Controllers

The Rachio model offers 8 or 16 zone options. At the same time, RainMachine offers an 8 or 16 zone option plus an additional 12 zone option.

While RainMachine offers only rain sensors, Rachio offers more sensors option with rain sensors, soil sensors, and flow sensors.

The two devices support a 2.4 GHz 802.11 b/g/n WiFi connection, but Rachio Gen 3 stands out for supporting 5 GHz.

One thing that makes RainMachine stand ahead of the Rachio is that it allows local connect, and it can still be used even when your WiFi is down.

The Rachio model is dependent on the cloud to carry out commands. On the other hand, RainMachine is self-reliant and does not depend on the cloud to carry out commands.

Both models are ideal for indoor use. However, RainMachine is not suitable for outdoor use in cold climates as it lacks weatherproofing.


RainMachine is the best smart irrigation controller that takes the number one spot between the two. The device is not only sleek and durable, but it also offers some exciting features and functionalities. The device works with Amazon Alexa's voice assistant that allows you to control it using your voice. It is also compatible with smart home hubs such as SmartThings so that you can manage all your smart devices from one centre. You can also use the touch interface on the device to give commands, which is a good plus as it gets the struggle away from using apps to control and monitor the device. 

One main advantage with the RainMachine smart irrigation controller is that it is not cloud-dependent, which means it will continue to function even when the WiFi is down. As such, you will only need to make your investment once while buying the device, and then from there, the device will remain functional.

Editor Notes:

Why we love the RainMachine more than Rachio is its ability to perform well in any situation, with or without connection.

As much as the Rachio Smart Sprinkler is ideal for outdoor use in cold conditions, this feature is not part of the sprinkler. You have to buy the Rachio Weatherproofing Casing, which adds to the amount you spend. If you consider the total costs you incur, especially with the sprinkler’s usual pricing being higher than RainMachine’s, the unit may not favor you if your budget is slim.

Not to mention, you have more zone options with the RainMachine than with Rachio.

However, Rachio also stands out with its 5GHz support and having more sensors. So, it still offers you a worthwhile alternative.
