OCPP 2.0.1

OCPP 2.0.1 reworks the protocol around a structured device model and consolidates the 1.6 start/stop messages into a single TransactionEvent. The emulator supports the core functional blocks plus security profiles 1–3.

What changed from 1.6

  • Device model — components and variables replace the flat configuration keys. Read with GetVariables / GetBaseReport, write with SetVariables.
  • TransactionEvent — Started, Updated, and Ended events replace StartTransaction / StopTransaction and carry richer context.
  • Security profiles — from basic auth (profile 1) to mutual TLS (profile 3).

Transaction events

A session is a stream of TransactionEvent messages:

[2, "msg-010", "TransactionEvent", {
  "eventType": "Started",
  "timestamp": "2026-01-01T00:00:00Z",
  "triggerReason": "Authorized",
  "seqNo": 0,
  "transactionInfo": { "transactionId": "tx-001" }
}]

Reporting

Use GetBaseReport to pull the full device model, then SetVariableMonitoring and NotifyEvent to test monitoring and alerting paths in your CPMS.
