Growatt Thor 11A/S Failed with response: Rejected after reload of integration

[altserg]

Describe the bug
I'm using Growatt Thos 11 A/S charger with firmware THOR_11AS-V5.2.4-20230307-NOVO. HASS Version: 2024.12.5, OCPP version: 0.7.0

I have noticed following problems with OCPP integration:

1. After the HASS restart or reload of OCPP integration there is OCPP "Failed with response: Rejected" warning in the HASS log. The warning floods the log file every second or so. There is no notification in HASS WEB interface. Further everything seem to work fine. There are 2 ways to get rid of the warning: physically power off/on the charger or press the reset button in the integration. If understand the sources correctly, the warning is probably in trigger_status_notification() function of ocppv16.py

• When Reset button is pressed after HASS reboot/OPP restart, there is "Stop transaction received for unknown transaction" error

To Reproduce

1. Configure the OCPP integration and Growatt charger according to the documentation
2. Disable the OCPP integration in HASS
3. Enable the OCPP integration in HASS
4. Review the HASS log with OCPP warning

Expected behavior

1. No warning occurs after HASS reboot/OCPP restart

I think that I have found the problem. OCPP lib log file is below. The charger reply to NumberOfConnectors variable is -1 . It's interpreted as 16 million, so the integration starts to query every connector, the charger rejects everything above 1. The charger reply after reset is 1 connector.

Proposed solution to change the async def trigger_status_notification(self) function and force correct # of connectors in case of configuration failure. Refer to lines 279-282 below

`
266 async def trigger_status_notification(self):
267 """Trigger status notifications for all connectors."""
268 return_value = True
269 nof_connectors = int(self._metrics[cdet.connectors.value].value)
270 for id in range(0, nof_connectors + 1):
271 _LOGGER.debug(f"trigger status notification for connector={id}")
272 req = call.TriggerMessage(
273 requested_message=MessageTrigger.status_notification,
274 connector_id=int(id),
275 )
276 resp = await self.call(req)
277 if resp.status != TriggerMessageStatus.accepted:
278 _LOGGER.warning("Status Notify Connector ID %d Failed with response: %s", id, resp.status)
279 _LOGGER.warning("Forcing number of connectors to %d", id - 1)
280 self._metrics[cdet.connectors.value].value = max( 1, id - 1 )
281 return_value = ( id > 1 ) #False
282 break
283 return return_value
