Customizing SmarIoT

SmarIoT should be fairly straight forward to customize. Here's the "big-picture" stuff:

The python (and flask) source is contained in a single file app.py.
templates directory contains Jinja templates and static directory contains the CSS files.
- main.css is use throughout the website
- iframe.css is used for iframes (duh!) on the homepage for dumping incoming raw JSON and on the /viz endpoint for showing line charts corresponding to each endnode
Javascript files are loaded off of CDNs. SmarIoT uses ChartJS ver 2.

ORM

SmarIoT uses the SQLAlchemy ORM toolkit
Two ORM classes are defined:
- DeviceData : Stores basic device (board/endnode) info (currently this is only being used to generate the endnode/device list)
- SensorData : Parses and stores sensor readings (this guy holds all sensor readings in the msg field)
hw_id is used to keep track of which endnode sent what

Data Parsing Functions

msg_parse_val contains the logic for interpreting raw payload data from TTN
This function WILL need to be modified to suit the data your hardware is sending

Adapting for source other than TTN

msg_get_hw_id, msg_get_value and msg_get_timestamp are abstractions for extracting the Hardware ID, Sensor Data and Timestamp respectively. These will need to be modified for as per the JSON structure
msg_parse_val will likely need to updated to remove the base64 decoding
censor_downlink_url will likely need to be removed (or updated)
