---

## v2 Requirements (Deferred)

- Graph/Chart views with extended time ranges
- Advanced alarm threshold configuration
- Calibration wizard
- Multiple station support
- Extended data export options

---

## Out of Scope

- **Mobile app** — Web-only interface
- **Cloud server** — RTU side only
- **Hardware sensor integration** — UI only
- **AI/predictive analytics** — Overkill for rainfall monitoring
- **3D visualizations** — Resource-heavy, not needed
- **Multi-touch gestures** — Error-prone, standard touch sufficient
