Converting MQTT broker payload to OCPP payload to transmit the data to the backend portal which is accepting only OCPP requests

[balavasudevan123]

Dear OCPP Experts,
My EV charger is currently transmitting the data to the backend portal using MQTT broker. Now we would like to create a python environment which is essential to handle OCPP communication through websockets in between Charger and the Backend portal. Because we don't want to disturb the charger which is integrated with the MQTT broker. So we planned to have a separate OCPP based python environment between the charger and backend portal.

This OCPP based python environment will do the following things.

• Receiving the MQTT broker's payload from charger
• Converting MQTT broker's payload to OCPP based payload
• Transmit the OCPP based payload to the backend portal through websocket using OCPP-J

I need to achieve these things with the new OCPP based python environment. I'm having strong python knowledge and I know about the packages Paho-MQTT and ocpp. But I need your help to understand how I can do the above process technically and also I need your best suggestions on the above scenario.

Looking forward to have a wonderful thoughts here.

Thanks much in advance friends!
