That's an extremely specific problem, but in general terms it's a simple solution.I have an Alessi 501 X-pert battery monitor on my boat. It’s about 20 years old (I know) but it does have an RS type socket and it can be set to output data like voltage etc to an attached computer. I would like to set up an RPI to read the output and broadcast it via wifi to the Internet for remote monitoring.
Does anyone have experience with such a project?
Have you ever connected it to any PC to get data? Does it have a manual that describes what it sends? Is the connector on the unit male or female?
If it really is RS232 it ought to be trivially easy to connect a USB serial cable from the Pi to it, open a serial monitor program such as gtkterm, and view some data. The next step would be figuring out what the data means, then write a simple program to capture it and put it somewhere that a webserver can find it and display it (probably a local sqlite database).
Done! Going to put my feet up now.
