arduino on I2C

[Sprokkie]

Hi Paddy,

i have nmea2000 and not nmea0183.
I look in the sketch and i see also mqtt do need that ?

where do you want to display the data ?
using node red it could be displayed on the dashboard, there would be no need for nema at all to arduino  ..
you could do alarms text email ect..
sk data can be read and actions taken in N.R. and sent back to arduino to do something open close relays ect.
arduino can read analog sensors and take actions in node red , display,or other actions..
so the short answer is Node-Red..
you will need a usb hub eventually..

really wonderfull gauge display, where did you get the gauges ?
i will google on arduino and node red, this might be the solution, only how to get the information from the arduino to the node red server ?
