App running on Python3.4

[nos86]

I'm running this application using python 3.4 on Windows, and I'm receiving warning because MQTT reading is byte based instead string (as expected).
I'm doing something wrong, or we need to improve the code?

I honestly don't know, but I suspect we need to improve the code. If you're up to it, I'll be happy to accept improvements. :-)
