Zone count sounds simple, but undersizing a controller can force a replacement when landscaping or drip irrigation expands later.
What matters most
Count every independently controlled valve and leave reasonable expansion capacity for future beds, drip zones, or landscape changes.
Where buyers get tripped up
A controller marketed as eight zones may still have separate limitations around master valves, pump relays, sensor inputs, or expansion modules.
What to verify before buying
Inspect the existing valve wiring, identify any unused conductors, and check how the controller handles master valves, pumps, and future expansion.
How we research smart irrigation
We compare water source, delivery method, zone or plant capacity, local fallback controls, schedule logic, connectivity, sensors, pump or valve compatibility, subscriptions, and what happens when internet service is unavailable.
Prices, specifications, firmware, inventory, and configuration-driven features can change. Check the current manufacturer or retailer page and local requirements before buying or installing equipment.
