A simple, Pythonic wrapper for the ChargePoint API.
Project description
python-chargepoint
A simple Pythonic wrapper around the ChargePoint EV Charging Network API.
DISCLAIMER
I, nor this project, are in any way associated with ChargePoint. Use this project at your own risk. ChargePoint is a registered trademark of ChargePoint, Inc.
I just wanted a way to retrieve and store charging data from my ChargePoint Home Flex in a way that is easy to model and query. This project is the first step in getting that data into a more robust time series database.

Starting or Stopping a Session
from python_chargepoint import ChargePoint
client = ChargePoint(username="user", password="password")
charging = client.get_user_charging_status()
if charging:
session = client.get_charging_session(charging.session_id)
session.stop()
# If you wanted to charge again, you can start a new session.
session = client.start_charging_session(session.device_id)
You can also start a new session by providing any device ID you want to start charging on.
from python_chargepoint import ChargePoint
client = ChargePoint(username="user", password="password")
home_flex_id = client.get_home_chargers()[0]
home_flex = client.get_home_charger_status(home_flex_id)
if home_flex.charging_status == "AVAILABLE":
session = client.start_charging_session(home_flex_id)
Setting the amperage limit
from python_chargepoint import ChargePoint
client = ChargePoint(username="user", password="password")
home_flex_id = client.get_home_chargers()[0]
# Print out valid amperage values.
print(client.get_home_charger_status(home_flex_id).possible_amperage_limits)
# [20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32]
client.set_amperage_limit(home_flex_id, 23)
print(client.get_home_charger_status(home_flex_id).amperage_limit)
# 23
