@Alex-Jochym I don't know if you have continued to work on this or have given up, but I created a project on hackster.io that does this. It pulls the location from the GPS module I have hooked up on the expansion board, but you can change the URL in the project to pull from specific stations by their ID. I have a weather station at my house that sends to WUnderground as well.
OK, new scripts have been created, I can now get the screen set up the way I want. All I have to do now is to read in the file and separate the data into the variables. I'm getting there, but slowly.
needs to be split so that I get back
If you have electronic knowledge, the simpler approach would be to bring the RS-232 voltage levels to 3.3V and use the Omega2 serial pins. If not, looks like the card reader device provides a USB interface as well. So, you would need to use some Linux USB api, perhaps just some read access to the /dev device, but I'm not familiar with the specifics yet (no Omega2 for me yet).
