Edge Devices
Edge Devices are the physical fleet in the field — sensors, controllers and embedded gateways. They are external to the platform: we control the contract (how they connect and what they send), not the firmware runtime itself.
Integration contract
Devices connect over MQTT secured with TLS client certificates. They publish telemetry upstream and subscribe to commands and desired-state downstream — a bidirectional, long-lived session.
