ocpp Python library 2.1.0 routing on decorator handler registration server ChargePoint documentation
💡 Result:
In **`ocpp` Python package 2.1.0**, `@on(...)` marks a method as the handler for an OCPP action. When a `ChargePoint` instance is created, it builds a route map from decorated methods; as messages arrive, it uses the action to find and invoke the matching handler. ([raw.githubusercontent.com](https://raw.githubusercontent.com/mobilityhouse/ocpp/2.1.0/ocpp/routing.py))
For a server, subclass the appropriate `ChargePoint`, decorate handler methods, then create an instance for each WebSocket connection and `await charge_point.start()`. The server-side documentation demonstrates this with `ocpp.v16.ChargePoint` and `@on(Action.boot_notification)`. ([ocpp.readthedocs.io](https://ocpp.readthedocs.io/en/stable/usage/server_side.html))
**Version distinction:** `2.1.0` here is the Python library’s version, not evidence of OCPP protocol 2.1 support. The documentation example is OCPP 1.6; the project README lists support for OCPP 1.6 and 2.0.1. ([github.com](https://github.com/mobilityhouse/ocpp/releases?utm_source=openai))

Emit an event for the Unknown authorization result.
When a charger sends an OCPP 2.0.1 Authorize request with a valid token type outside ISO14443, ISO15693, and Central, on_authorize returns Unknown without calling get_authorization_status. That result bypasses the event, despite the test’s stated “Every decision” expectation. Emit the existing status through the shared event path without looking up or changing authorization.

Assume the user would also want to know the connector id?
There was a problem hiding this comment.
@drc38 Yes. A connector_id would help automations target the correct connector on a multi-connector charger.
However, an Authorize request does not include a connector ID. I would make the event field nullable:
- For OCPP 1.6
StartTransaction, pass the suppliedconnector_id. - For
Authorize, emit"connector_id": null. Do not infer the connector or default to1. - For OCPP 2.0.1 transaction events, include
evse_idas well when available. The connector ID is scoped to the EVSE.
The shared event emitter can accept this optional context. The Unknown authorization result should still emit an event, even when no connector is known.

Fixed, unchecked 2.0.1 token types now fire the event with Unknown.
There was a problem hiding this comment.
Added connector_id. StartTransaction sets it, Authorize carries no connector in either protocol, so it is null there.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy liftEmit the authorization event for OCPP 2.0.1 transaction tokens.
If a charger accepts a token locally and sends it only in
TransactionEvent,on_authorizenever runs. This handler answersAcceptedfor the token but emits noocpp_authorizationevent. Publish that decision with the resolved connector ID. Also handle the immediateAcceptedresponse in the inventory-buffered path, and avoid publishing the same decision again during replay or later updates.
