Communication Methods for Offline-First Controllers
Context
Discussion originated from Matrix room #architecture.
Problem
Controllers must operate reliably under intermittent connectivity.
Options Considered
- MQTT
- HTTP polling
- LoRa-based messaging
- Local mesh networks
Findings
- MQTT requires stable broker connectivity; may fail under prolonged offline periods.
- HTTP polling is simple but inefficient in bandwidth-constrained environments.
- LoRa is suitable for low bandwidth but offers limited throughput and higher latency.
- Local mesh networks can provide autonomy but require complex topology management.
Conclusion
For AOWIS reference implementations, MQTT with local buffering is preferred to maximize reliability while minimizing complexity.
Open Questions
- What is the optimal synchronization strategy for buffered messages?
- How should conflicts be resolved in offline scenarios?
