What is your exactly your problem? If you start rc.local proposed in my previous post than your problem has been solved. The only thing is you have to do some tweaks.
Modify analitico.py for systemd
1) Add time.sleep(20)
2) Remove the while loop and try except stuff inside the while loop too.
You don't need the while loop.
3) disable invia_analitici() by placing a # before that instruction
4) keep in mind goolge stuff is not needed for a simple test. If everything works fine than enable that instruction.
Start your analitico.sh and see what happens.
Remember analitico.sh does not open a terminal so you don't see any output. The output is redirected to a log file analitico.log.
