ChargePoint Station Occupancy Scraper with Boxcar and OS X Notification Center support

by Nicholas Robinson

Overview

This software allows for convenient monitoring of ChargePoint station occupancy via a text-based user interface. Additionally, it supports OS X Notification Center and Boxcar notifications, which are triggered whenever a new charging spot becomes available. This gives you a much needed advantage in an office charging environment where contention for charging spots is high!

Requirements

  • Python 2.7+
  • Virtualenv
  • OS X 10.8+ (for Notification Center)
  • Boxcar account + compatible device (for Boxcar notifications)

Installation

$ git clone git://github.com/nicholasrobinson/ChargePoint-Scraper.git
$ cd ChargePoint-Scraper/
$ virtualenv v_env
$ source v_env/bin/activate
$ pip install -r requirements.txt
$ vim main.py 
(replace BOXCAR_ACCESS_TOKEN with your Boxcar access token)
$ vim chargepoint_scraper.py
(replace DEFAULT_LATITUDE and DEFAULT_LONGITUDE definitions with <YOUR_LATITUDE> and <YOUR_LONGITUDE>)

Execution

$ ./main.py
(enter your ChargePoint username and password when prompted)

Sample Output Explanation

The above output shows 19 ChargePoint stations (indicated by the column headings) and their availability every minute (indicated by the row headings). The x/y entries in each cell indicate that x spots out of y total spots are currently unoccupied.

Notes

In main.py the

poll_chargepoint_stations(s)

can be replaced with

poll_chargepoint_stations(s, stations_of_interest=stations, stations_to_ignore=ignore)

where stations_of_interest and stations_to_ignore kwargs allow you to specify stations you are interested in and/or would like to exclude.

Please let me know if you find this useful or come up with any novel implementations.

Enjoy!
