Assuming you don’t live in California, on the moon, or somewhere equally dry, this intelligent Rachio irrigation controller can keep your lawn green with practically zero work on your part.

The Rachio IRO can control sixteen different zones in your yard, and automatically adjusts watering schedules based on the weather. 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. All of these smarts mean that the IRO can save you 30% on your outdoor water use, so it 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.

Today’s $200 deal is reserved for Prime members, but it matches an all-time low, and is well below its usual $300 asking price. [Rachio IRO Smart Irrigation Controller, $200 for Prime members]
