WiCAN ESP32-based open-source OBD2/OBD-II Vehicle (car or truck) CAN Bus Diagnostics to WIFi/BLE/USB adapter for Home Assistant integration?

Got it working with your help/post. but unfortunately my car (Peugeot boxer 2011) does not provide the fuel level on PID 47. It’s just zero. Any ideas here? I think it’s not possible to get this value with my car. As this was the only reason for me to use this device, I have now one to sell (coming from Germany).
