In-depth reviews of the top weather-based smart controllers that save $300-800 annually
🏆 Our Top Picks at a Glance

Smart irrigation controllers are the single highest-ROI investment for reducing your water bill. By automatically adjusting watering based on weather, soil moisture, and evapotranspiration rates, these controllers typically reduce outdoor water use by 30-50% and save $300-800 annually.
Unlike traditional timers that run the same schedule regardless of conditions, smart controllers skip watering when it rains, reduce runtime during cool weather, and increase watering during hot, dry periods - all automatically.

- Smartphone or tablet for app setup
- WiFi network (2.4GHz for most controllers)
- Optional: Wire strippers if wires are damaged
Installation Steps (30-60 minutes)
- Document old controller: Take photos of existing wire connections
- Turn off power: Shut off circuit breaker or transformer
- Label wires: Mark each wire with its zone number before disconnecting
- Remove old controller: Unmount and disconnect
- Mount new controller: Use included mounting bracket
- Connect wires: Match zone numbers to new controller terminals
- Restore power: Turn on breaker/transformer
- Download app: Follow in-app setup wizard
- Configure zones: Enter plant type, soil type, sun exposure for each zone
- Test system: Run each zone briefly to verify proper operation
💡 Installation Tips
- Most issues come from incorrect wire connections - take your time and double-check

- If your controller is hardwired (no plug), consider hiring an electrician for $75-150
- Most manufacturers offer phone support during installation - don't hesitate to call
- WiFi signal must reach controller location - test beforehand or use WiFi extender

Frequently Asked Questions
Do smart controllers really save that much water?
Yes - EPA studies show 30-50% reduction in outdoor water use is typical. Your actual savings depend on how inefficient your old system was. If you were running a basic timer that watered the same amount every day rain or shine, you'll see dramatic savings. If you were already manually adjusting for weather, savings will be more modest (15-25%).
Will my utility rebate work with any of these controllers?
All four controllers reviewed here are EPA WaterSense certified and should qualify for any utility rebates that exist in your area. Always verify with your specific utility before purchasing.
Can I install this myself or do I need a professional?
95% of homeowners can install these controllers themselves in 30-60 minutes. The only exception is if your existing controller is hardwired (no plug) rather than using a plug-in transformer - in that case, hire an electrician for safety.
What if I don't have WiFi in my garage?
Consider a WiFi extender ($25-40) to extend coverage to the controller location, or choose the Orbit B-hyve which can work via Bluetooth if your controller is within 100 feet of where you typically are with your phone.
How long do these controllers last?
Most smart controllers last 7-10 years with proper care. Rachio's 5-year warranty is industry-leading and suggests they expect their units to last significantly longer. The electronics rarely fail - most issues are related to WiFi connectivity or user error in setup.
