StatusNotifications 2.0.1

🔄 StatusNotification: OCPP 1.6 vs 2.0.1

Purpose: The StatusNotification message informs the backend system about the current status of a connector (e.g. Available, Charging, Faulted).

🧾 Key Differences

Feature OCPP 1.6 OCPP 2.0.1
Message Direction Charge Point → CSMS EVSE → CSMS
Context Sent per connector Sent per EVSE (new structure)
Connector Structure connectorId (flat model) Hierarchical: evseId + connectorId
Status Values Fixed enums Expanded enums + more granular statuses
Timestamp Optional Mandatory (more precise tracking) Extensibility Limited Highly extensible with richer diagnostics

✅ Example Use Cases

OCPP 1.6: Suitable for simpler infrastructures with basic status reporting.

OCPP 2.0.1: Better for smart charging, richer diagnostics, and advanced monitoring in complex EVSE deployments.
