I've been using processing.org to capture data from Arduinos. I haven't tried with an RPi yet, but the link here is dedicated to just that.
Processing is more geared for doing really fancy graphics, but its ability to capture data and put it to a file is great, and, of course, send data to the Arduino.
I am inexperienced in interprocess communication, but, apparently processing can put the data out to MQTT check this link
Let me know how that works out for you!

I am using them at 12V so the power would be ~4W. Not too much but still enough to get the sink hot!
The voltage makes no difference. 5A is still 5A.
you are right brain fart
this kind of optic fiber is probably only plastic so for a full DIY , you can use also fishing wire with a big power led or an old chistmass tree optic fiber lighted.....
