NeverDry is a custom integration that calculates a real-time soil water deficit using a scientific water balance model (FAO-56 simplified). It tells you exactly when and how long to irrigate each zone of your garden.
- Per-zone crop coefficient (Kc) with 10 plant families and seasonal variation
- Direct valve control with sequential multi-zone irrigation
- Rain-aware — skips irrigation automatically on rainy days
- Metric & imperial — all sensors carry HA device classes; units follow your HA system preference automatically
- Monitoring mode — works without smart valves (notification alerts)
- UI config flow — no YAML needed
- Home Assistant 2024.1.0+
- Outdoor temperature sensor (°C)
- Rain sensor (mm/event)
- Optional: smart valve(s), soil moisture sensor
