The best smart-sprinkler products
Rachio (Generation 2) Smart Sprinkler is the best choice for most people with an in-ground sprinkler system. here are some feature:

- Offers simple plug-and-play functionality and the option to fine-tune irrigation system with advanced settings.
- The onboard touchscreen is less functions, you may have to be tied to an app or an Internet connection.
- If the Internet is down, you won’t be able to adjust any schedules on the device or through the app and automatic weather adjustments won’t work either. (But the Rachio will continue to run on its preprogrammed schedules)
It’s like like Rachio above. But if you don’t want to be tied to an app or an Internet connection, the RainMachine Touch is a good choice. The RainMachine Touch is not only be controlled by a smartphone app or Web interface, it also has an onboard touchscreen that lets you control every functions.
- The RainMachine connects to the internet only to get weather data. You can still control it with your phone, tablet or computer over local network.
- Full-controlling from the onboard touchscreen in case the Wi-Fi is down.
- The app is less intuitive (compared with Rachio).
- Requires more information of your landscape and irrigation system for optimal setup.

It is the perfect sprinkler timer for new installations or for replacement, and available in both 6 and 12 zones.

- A drag-and-drop interface makes the app intuitive, speedy, and attractive.
- It comes in a waterproof, lockable case, so there is no extra expense if you want to put it outdoors.
- Offers direct Alexa integration.
- Not good looking, like a clock—big, heavy, and bulky—and comes with the traditional A, B, C programs that irrigation experts are familiar with.
- Many user reviews reported that the app is very buggy: Some time it’s crashed, cancelled out the smart watering schedule entirely for no clear reason, somehow enabled restrictions (although our program was set to run, it didn’t).

From user experience
It is the most fine-tuned control you can get for your yard. The BlueSpray Irrigation Controller have the expansion port which can extends up to 64 zones (it’s ideal if you live in a mansion or run a farm or or own a golf courses).
It’s not easy to program and doesn’t adjust its schedule based on the weather but the controller will let you run multiple schedules, multiple zones, and even multiple master valves simultaneously (most homes don’t need that)
Doesn’t havean app or any on-device controls, it’s only have Web UI (but looks complex and pretty dated). It also doesn’t have smart-home integrations, but it does have an API and an optional Ethernet connection.
