pybluecurrent 0.3.0rc1

Python client for BlueCurrent charge points.

pybluecurrent

Python client for BlueCurrent charge points.

Usage

Using the client is as simple as:

from pybluecurrent import BlueCurrentClient

client = BlueCurrentClient("your_username", "your_secret_password")

async with client:
    charge_points = await client.get_charge_points()
    transactions = await client.get_transactions(charge_points[0]["evse_id"])

Methods

The BlueCurrentClient exposes the following methods:

• get_account
• get_api_token
• generate_api_token
• get_charge_cards
• get_charge_points
• get_charge_point_settings
• get_grid_status
• get_sustainability_status
• set_plug_and_charge_charge_card
• set_status
• login
• get_charge_point_status
• set_delayed_charging
• set_delayed_charging_schedule
• set_price_based_charging
• set_price_based_charging_settings
• boost
• get_contracts
• get_grids
• get_transactions
• iterate_transactions

Connection

The client can only be used when the websocket client is connected. For example:

client = BlueCurrentClient("your_username", "your_secret_password")
async with client:
    result = await client.get_account()

Entering the async context will automatically login.

Instead of a username and password, you can authenticate with an API token:

client = BlueCurrentClient(api_token="your_api_token")

Retrieve or rotate the token with get_api_token and generate_api_token, or from the BlueCurrent website.

get_account - Get your account information.

async def get_account(self) -> dict[str, bool | str]

Returns

A dictionary describing your account:

{
    "full_name": "Your Full Name",
    "email": "[e-mail]",
    "login": "[e-mail]",
    "should_reset_password": False,
    "developer_mode_enabled": False,
    "tel": "",
    "marketing_target": "bluecurrent",
    "first_login_app": datetime(2020, 1, 15, 13, 33, 52),
    "hubspot_user_identity": "a_very_long_string"
}

get_api_token - Get your API token.

async def get_api_token(self) -> str

Returns the API token (home automation key) for your account. This token can be used to authenticate instead of a username and password, by constructing the client with BlueCurrentClient(api_token=...).

generate_api_token - Generate a new API token.

async def generate_api_token(self) -> str

Generates a new API token and returns it. Warning: this rotates the token — any previously issued token is invalidated, which will break anything still using the old one (for example a Home Assistant integration).

get_charge_cards - Get your charge cards.

async def get_charge_cards(self) -> list[dict[str, date | int | str | None]]

Returns

A list of dictionaries, each representing a charge card:

{
    "uid": "A1B2C3D4E5F6",
    "id": "NL-ABC-123456-0",
    "name": "My Charge Cards",

}

get_charge_points - Get your charge points.

}

set_delayed_charging - Enable or disable delayed charging.

async def set_delayed_charging(self, evse_id: str, enabled: bool) -> None

While delayed charging is enabled, the charge point only charges within the window configured with set_delayed_charging_schedule, and delays charging outside of it. A charge point has at most one smart charging profile active, so enabling delayed charging disables any other profile.

Arguments

• evse_id: The ID of the charge point.
• enabled: Boolean that indicates whether delayed charging should be enabled.

set_delayed_charging_schedule - Set the delayed charging schedule.

async def set_delayed_charging_schedule(
    self,
    evse_id: str,
    start_time: time | str,
    end_time: time | str,
    days: Iterable[Weekday | int | str],
) -> None

Sets the window in which the charge point may charge on the selected days. The window may span midnight. It is only applied while delayed charging is enabled with set_delayed_charging.

from datetime import time
from pybluecurrent import Weekday

await client.set_delayed_charging_schedule(
    "BCU123456", start_time=time(23, 0), end_time=time(7, 0), days=[Weekday.MONDAY, "tu", 3]
)

Arguments

• evse_id: The ID of the charge point.
• start_time: The time at which charging may start, as a time or a "HH:MM" string.
• end_time: The time at which charging must stop, as a time or a "HH:MM" string.
• days: The days on which the schedule applies. Each day may be a pybluecurrent.Weekday, an isoweekday number (1 for Monday through 7 for Sunday), or a weekday name such as "monday" or "mo".

The schedule is read back from the delayed_charging key of get_charge_point_settings.

set_price_based_charging - Enable or disable price-based charging.

async def set_price_based_charging(self, evse_id: str, enabled: bool) -> None

While price-based charging is enabled, the charge point charges during the cheapest hours before the expected departure time, as configured with set_price_based_charging_settings. A charge point has at most one smart charging profile active, so enabling price-based charging disables any other profile.

Arguments

• evse_id: The ID of the charge point.
• enabled: Boolean that indicates whether price-based charging should be enabled.

set_price_based_charging_settings - Set the price-based charging settings.

async def set_price_based_charging_settings(
    self,
    evse_id: str,
    expected_departure_time: time | str,
    expected_kwh: float,
    minimum_kwh: float,
) -> None

Configures how much energy to charge before departure. Only applied while price-based charging is enabled with set_price_based_charging.

Arguments

• evse_id: The ID of the charge point.
• expected_departure_time: The time the vehicle is expected to leave, as a time or a "HH:MM" string. Note this is read back as expected_leave_time from the price_based_charging settings.
• expected_kwh: The amount of energy, in kWh, expected to be charged before departure.
• minimum_kwh: The amount of energy, in kWh, to charge immediately regardless of price.

The settings are read back from the price_based_charging key of get_charge_point_settings.

boost - Charge now, overriding the active smart charging profile.

async def boost(self, evse_id: str) -> None

Starts charging immediately, overriding whichever smart charging profile is currently delaying charging — delayed charging or price-based charging — for the ongoing session. The override cannot be undone. While it is active, get_charge_point_status reports "boosting": True. Raises ValueError if no smart charging profile is active.

Arguments

• evse_id: The ID of the charge point.

get_contracts - Get your contracts.

async def get_contracts(self) -> list[dict[str, str]]
