Key Generation Differences Between Rachio Controllers

Rachio 2 - Extra - 01

Zones – Almost all Rachio controllers support 8 and 16 zone control except for the Rachio 3e which only supports an 8-zone control

Manual Control – In case you don’t have your phone on you, it’s nice to be able to make basic adjustments to the preset watering schedule right from the unit. Fortunately almost all Rachio models provide manual control, except for the Rachio Gen 1 which requires access to the Rachio app to be controlled.

It’s worth noting that Rachio Gen 2 has run, pause, and skip buttons under the front panel which makes it as uncomfortable as it sounds like. Whereas the Rachio 3 and 3e have run, pause, and skip buttons right on the main panel.

Wired Flow Sensors – With flow sensors you can check your sprinkler’s actual water consumption in gallons. It’s a useful accessory to help you monitor the actual flow of water running through pipes. Unfortunately, Rachio Gen 1 doesn’t support wired flow sensors. However, all other Rachio controllers, Gen 2, Gen 3, and 3e do support them.

Wireless Flow Meter – This feature is exclusive for the Rachio Gen 3 only. The wireless flow meter will detect leak and blockage to notify you as soon as possible. Moreover, it’ll instantly shut off zones where leaks are detected. 

Flex Daily – Rachio offers three types of watering schedules: Fixed, Flex Monthly, and Flex Daily.

Flex Daily is only available for the Rachio Gen 2 and Gen 3. With Flex Daily, your Rachio controller will be checking for hyperlocal weather forecasts, moisture levels, and individual zone characteristics daily to determine the best watering for each zone in particular. This is a super customized feature that will make sure your plants will get enough water to be green and happy. 

Weather Intelligence – All Rachio sprinklers support weather intelligence, to a certain degree. Rachio Gen 1, Gen 2, and Gen 3e feature standard intelligence, whereas the Gen 3 model comes with advanced technology. 

The difference between standard weather intelligence and advanced one is the Self-Healing function. With the standard version, you’ll have a selected weather station which Rachio will use to set up watering schedules. The advanced version, on the other hand, has this self-healing function which will switch to the closest reporting station in case your standard weather station stops reporting data for three days or more. It’ll also send you an email to notify you about the change.

Yard Map – With the Yard Mao feature you can improve water usage reporting by customizing sprinkler heads and drawing your zone boundaries. 

The Yard feature is only available for a limited line of 12-zone controllers available only at Costco. It’s also available for Rachio 3 controllers that use the Rachio Wireless Flow Meter.

Other than that, the Rachio Gen 1, Gen 2, and Gen 3e controllers do not support this feature.  

Wi-Fi Connection – Rachio Gen 1 and Gen 2 run on 2.4Ghz, whereas the Gen 3 and 3e can use either 2.4Ghz or 5Ghz. The 2.4Ghz offers longer range but slower speeds while the 5Ghz provides less coverage but it’s way faster at transmitting data. Also, the more devices you have on the 2.4Ghz network, the lower the speed is.

So if you already have a lot of devices on your 2.4Ghz network, then Rachio Gen 3 and 3e are the way to go. Just make sure your router supports 5Ghz.

HomeKit – The only Rachio controller that supports HomeKit is the Gen 3 model. So, if you use HomeKit and control your smart tech via Home app and Siri, then it goes without saying that Rachio Gen 3 is for you.

It’s important to note that all Rachio controllers support Amazon Alexa and Google Assistant. So they all offer smart voice control, it’s just Siri is unique to Rachio Gen 3 only.

Future premium software features – As you can tell, out of all four models the Gen 3 is the most advanced, thus it has support for future premium software features. Unfortunately, we can’t say the same about the Gen 1, Gen 2 and Gen 3e models.

Which Rachio Controller is Perfect For My House?

you want a total control of your front/back yard, all the stats and reports, even from wireless flow meters, and a super customizable daily schedule. Not to mention, Rachio Gen 3 is the only Rachio controller that supports HomeKit, so it’s a no-brainer for Apple fans.
