Smart home automation can meaningfully reduce your utility bills by controlling two things precisely: water and electricity. We tested the top smart sprinkler controllers and lighting hubs to find which ones actually save you money — from the weather-smart Rachio 3 to the budget-friendly Wyze sprinkler and the reliable Lutron Caseta lighting system.
Heating, cooling, lighting, and watering your yard add up fast — the average U.S. household spends about $2,000 a year on utilities, with outdoor water use alone accounting for nearly 30% of total household water consumption.1 The good news? Smart home devices can chip away at those numbers by automating the boring stuff: turning off lights when nobody's home, skipping a watering cycle when rain is forecast, and scheduling everything around your actual life.
We looked at four devices that tackle the two biggest levers — water and electricity — and ranked them by how much they can realistically save you.
| Rank | Device | Best For | Key Feature |
|---|---|---|---|
| 1 | Rachio 3 | Maximum water savings | Weather intelligence + hyperlocal forecasts |
| 2 | Orbit B-hyve | Mid-range value | Real-time weather data + remote management |
| 3 | Wyze Smart Sprinkler | Budget entry | Basic weather skipping |
| 4 | Lutron Caseta | Lighting automation | Reliable scheduling + dimming |
The Rachio 3 is the gold standard for smart irrigation. It uses hyperlocal weather data — temperature, rainfall, humidity, wind, and soil moisture estimates — to build a watering schedule that adapts daily.1 If a storm rolls in, it skips the next cycle automatically. If a heatwave hits, it adjusts run times to keep your lawn alive without waste.
Why it's #1: No other controller in this lineup matches the depth of Rachio's weather intelligence. The company claims users save an average of 30–50% on outdoor water use, and given how granular the scheduling gets, that number is believable. It's also the easiest to set up if you have a compatible smart home hub.
Orbit's B-hyve line brings weather-responsive scheduling at a lower price point than Rachio. It connects to Wi-Fi, pulls real-time weather data, and lets you control everything from the app — start, stop, or delay watering from anywhere.2
Where it shines: The B-hyve is a great pick if you want most of the smart features (weather skip, remote control, zone-by-zone scheduling) without paying flagship prices. It's slightly less refined than the Rachio in terms of forecast granularity, but for most lawns, it'll get you 80% of the savings at 60% of the cost.
Wyze brings its signature "good enough at a low price" approach to sprinkler controllers. The Wyze Smart Sprinkler offers basic weather skipping — it checks local forecasts and pauses watering when rain is expected.3
The trade-off: You don't get the deep weather intelligence or multi-day adaptive scheduling of the Rachio. But if your main goal is to stop watering during a rainstorm (which is where most waste happens), this does the job for a fraction of the price. It's a solid entry point if you're not ready to invest heavily in irrigation automation.
Water is one half of the bill; electricity is the other. Lutron Caseta is a lighting control system that lets you schedule lights, dim them remotely, and set them to turn off automatically when you leave a room.4
Why it matters for savings: The U.S. Department of Energy estimates that lighting accounts for about 10% of a home's electricity bill. Automated scheduling — making sure lights are never on in an empty house — is the simplest way to cut that number. Caseta also works with most major smart home platforms (Alexa, Google Home, Apple HomeKit), so it fits into an existing setup without friction.
Let's be realistic. A smart sprinkler controller won't cut your total utility bill in half. But the math works:
Combined, you're looking at $200–340 in annual savings — enough to pay for the devices themselves within the first year or two.
If you want the best water savings, get the Rachio 3. If you want a solid middle ground, the Orbit B-hyve delivers. For a low-cost entry, the Wyze Smart Sprinkler covers the basics. And for lighting, Lutron Caseta is the most reliable way to stop wasting electricity on empty rooms.
