Rachio brought home sprinkler systems into the smartphone age, and their 8-zone system has its biggest discount ever today on Amazon.

These controllers can automatically adjust watering schedules based on the weather, and if you want to keep tabs on it, its iOS and Android app will show you how much water you’re using (and saving), and allow you to make any adjustments necessary, no matter where you are in the world. They even work with Alexa, so you can water your lawn with nothing but your voice. All of these smarts mean that you can save over 50% on your outdoor water use, so the Rachio should pay for itself over time. It’s also EPA WaterSense Certified, meaning your local water company might offer you a rebate for purchasing it.
