1. Zone Count — Count First, Buy Second
Every independent watering area is one zone. Count carefully before purchasing:
| Yard Type | Typical Zones | Best Pick |
| Small yard under 5,000 sq ft | 4–6 zones | Orbit B-hyve XD 6-zone |
| Medium yard 5,000–15,000 sq ft | 6–10 zones | Rachio 3 8-zone |
| Large yard 15,000+ sq ft | 10–16 zones | Rachio 3 16-zone |
| Estate / complex system | 16+ zones | Hunter Hydrawise 24-zone |
2. Weather Intelligence Type
