Status Notification

Source: OCPP 2.0.1 Part 2 — Specification (Edition 2, 2022-12-15) — Section 1.59 (Messages); Use Case G01 — Status Notification (Functional Block G. Availability)

Overview

The Charging Station sends StatusNotificationRequest to inform the CSMS about a change of connector status (Available, Occupied, Reserved, Unavailable, Faulted).

In OCPP 2.0.1, status reporting is much simpler than in 1.6 — the connector status enum has only five values, error reporting has been moved to NotifyEvent (Device Management Monitoring), and connector identity is split into evseId + connectorId.

NOTE (from spec): This message might be removed in a future version of OCPP — it will be replaced by Device Management Monitoring events.
