Upgrades
Smart controllers & drip
Smart controllers adjust watering based on weather, and drip lines water beds and gardens at the roots. Both are common upgrades to existing systems.
Common upgrades
- Wi-Fi controllers you can run from your phone
- Rain and soil moisture sensors
- Converting spray zones in beds to drip
- Adding zones for new landscaping
Good to know
Ask whether your existing wiring and valves work with the new controller, and who sets up the schedule.
Methods, parts and prices vary by company. Ask each one what's included and whether parts are extra.
Features worth comparing
| Feature | Why it helps |
|---|---|
| Weather-based scheduling | Skips or shortens watering after rain |
| Phone app | Run, pause or adjust zones from anywhere |
| Soil or rain sensors | Waters by actual conditions |
| Flow monitoring | Can alert you to leaks or broken heads |
| Zone count | Must match or exceed your system |
Drip conversions
Spray heads in flower beds often wet leaves, walls and walkways. Converting those zones to drip puts water at the roots, reduces runoff and can help plants stay healthier. Many companies convert one zone at a time.

Setting it up well
A smart controller works best when each zone is set up with the right plant type, sun exposure, soil and slope. Ask the installer to set those details, not just connect wires. Check the schedule after a few weeks and adjust if any areas are too wet or too dry.
