Edge Computing

OttO is a Go-based IoT edge gateway that connects sensor stations, MQTT messages, REST APIs, WebSocket dashboards, and application logic at the boundary between devices and backend systems.

A practical five-layer model for IoT systems, showing how devices, protocols, edge runtime, backend services, and applications fit together.

How the OttO IoT gateway uses MQTT to receive telemetry from device stations, parse topic-based sensor identifiers, pass readings through Go channels, and protect the gateway from unbounded in-memory growth.
