ChargePoint

✓ import ocpp

✗ from ocpp import ChargePoint

Minimal example creating a charge point client and sending a BootNotification.

import asyncio import logging from ocpp import ChargePoint from ocpp.v16 import call logging.basicConfig(level=logging.INFO) class ChargePointClient(ChargePoint): async def send_boot_notification(self): request = call.BootNotificationPayload( charge_point_vendor='vendor', charge_point_model='model' ) response = await self.call(request) logging.info(f"Boot response: {response}") async def main(): cp = ChargePointClient('id', None) await cp.send_boot_notification() asyncio.run(main())

Known issues

breakingIn v2.0.0, the library dropped support for Python <3.11 and renamed several internal classes.

fix

Upgrade to Python >=3.11 and adjust imports: Payload classes are now in ocpp.v16.call and ocpp.v16.call_result instead of ocpp.v16.datatypes.

affects: >=2.0.0,<2.1.0

gotchaWebSocket connection is not part of the library; you must provide your own transport (e.g., websockets).

fix

Use websockets library to connect and pass the socket to ChargePoint constructor.

affects: all

deprecatedThe 'Payload' suffix on call/call_result classes is deprecated in favor of un-suffixed names.

fix

Use BootNotification instead of BootNotificationPayload (still works but will be removed).

affects: >=1.0.0-rc.1
