"""
This is a very trivial script that logs into a user's account and prints out useful data for a "NOAH" system.
This has been tested against my personal system (NOAH2000) which is a 2kW Balcony Storage system.

Throughout the script there are points where 'pp.pprint' has been commented out. If you wish to see all the data that is returned from those
specific library calls, just uncomment them and they will appear as part of the output.
