Buying Guide
- Zone capacity: Choose the number of zones you need now and anticipate expansion. Higher zone controllers offer more future flexibility.
- Power and installation: Battery or plug‑in options suit different sites. Indoor versus outdoor placement affects durability and weather resistance.
- Weather awareness: Weather‑adaptive features cut water waste and protect plants during adverse conditions. Ensure compatibility with local climate data if available.
- Connectivity: WiFi or app control provides remote management but adds reliance on network stability. Consider offline controls as a backup.
- Future upgrades: If you expect to add smart features later, plan for a model that supports optional modules or cloud connectivity.
