thx Paddy,
Managed to get this working via node-red.
Signalpath: Sensor (I2C or SPI)--> arduino --> USB(serial) --> Openplotter PI --> Serial interface node-red
Point now is that in the real practice the sensor has to be installed outside, harsh environment, seawater. So USB is not the correct way i think. ESP8266(wifi) is not reliable on an aluminium boat. So thinking of RS485. N2k looks to complex to me
