Buying Guide: Key Considerations For Open Source Style Controllers
- Zone capacity: Match the number of zones to your landscape. Larger properties benefit from 12–16 zones, while smaller lawns may do well with 6–8 zones.
- Weather intelligence: Look for automatic rain, wind, and freeze skips. This feature reduces watering during adverse conditions and saves water.
- App control and scheduling: Ensure the app provides intuitive scheduling, remote access, and real-time monitoring across all zones.
- Indoor vs. outdoor installation: Decide whether you need a weatherproof outdoor unit or an indoor controller with weatherproof housing for exterior use.
- Installation effort: Some models require wiring and setup in a garage or shed; others are simpler plug-and-play with minimal wiring.
- Water conservation features: Cycle-and-soak modes and plan-based watering minimize runoff and promote healthy soil infiltration.
- Reliability and support: Consider devices with consistent firmware updates and documented customer support resources.
