FYI, some examples for you of various ways to call ChargePoint APIs:

https://lefthandwriter.github.io/software/2018/06/22/Designing-EV-Database.html
https://github.com/lefthandwriter/ChargePointAPI/blob/master/createEVdb.py

https://github.com/nicholasrobinson/ChargePoint-Scraper/blob/master/main.py

Can you please give more detail on where we are supposed to edit the config file? Are we to add
chargepoint:
email: [email protected]
password: SECRET

temporarily this is required (see MITM steps below)

userid: 0000000
secret: 'AAAAAAA'
to the configuration.yaml file? or is there a config file for charge point?

Here is how I've found the userid and secret, without needing to mitm the app:

1. Log in to chargepoint.com
2. Visit https://na.chargepoint.com/index.php/nghelper/getSession
3. Find the userId in the json response
4. Find the session id by opening the browser's Inspector/Devtools, going to the "Storage" tab, under "Cookies", it is listed as "coulomb_sess".

Feel free to incorporate this in the readme.
