# ADR 0001: Initial Architecture Decisions
|
|
|
|
**Date**: 2026-06-19
|
|
**Status**: Accepted
|
|
|
|
## Context
|
|
|
|
We need a monitoring system for small water systems that is affordable, low-egress, and usable by both non-technical owners and professional operators.
|
|
|
|
## Decision
|
|
|
|
We will use a hybrid edge + cloud architecture with:
|
|
- Raspberry Pi 5 edge devices
|
|
- Tiered telemetry (compressed healthy summaries + rich alert payloads)
|
|
- Monitored Objects as the core abstraction
|
|
- Hybrid AI (small edge models + larger cloud models)
|
|
- Multi-tenant web application with role-based access
|
|
|
|
## Consequences
|
|
|
|
- Strong emphasis on local processing to control data costs
|
|
- More complex initial onboarding (AI interview + camera mapping)
|
|
- Clear separation between Basic (owner) and Advanced (operator) dashboard views
|
|
|
|
## Alternatives Considered
|
|
|
|
- Pure cloud SCADA (too expensive for small systems)
|
|
- Fully on-prem with no cloud (loses multi-system operator view and easier updates) |
