Asyncio Duke Energy

Installation

Install this via pip (or your favourite package manager):

pip install aiodukeenergy

Usage

Duke Energy uses Auth0 with CAPTCHA protection which blocks automated logins. Authentication requires a browser-based OAuth flow using a Chrome extension to capture the mobile app's custom redirect URL.

Setup

1. Install the Chrome extension:

   • Download the latest chrome-extension.zip from releases (or use ./chrome-extension/ from source)
   • Extract the zip file
   • Open Chrome and navigate to chrome://extensions/
   • Enable "Developer mode"
   • Click "Load unpacked" and select the extracted folder

2. Run the browser authentication script:

   cd examples
   python browser_auth.py
   

3. The script will:

   • Open your browser to Duke Energy's login page
   • After you log in, the extension captures the authorization code
   • Exchange the code for API tokens
   • Save tokens to duke_tokens.json

Using Tokens

Once you have tokens, use them with the library:

import asyncio
import aiohttp
from aiodukeenergy import Auth0Client, DukeEnergy, DukeEnergyAuth


async def main():
    # Option 1: Load from token file
    import json

    with open("duke_tokens.json") as f:
        tokens = json.load(f)

    async with aiohttp.ClientSession() as session:
        auth0_client = Auth0Client(session)
        auth = DukeEnergyAuth(
            session,
            auth0_client,
            access_token=tokens["access_token"],
            refresh_token=tokens.get("refresh_token"),
            id_token=tokens.get("id_token"),
        )

        client = DukeEnergy(auth)

        accounts = await client.get_accounts()
        print(accounts)

        meters = await client.get_meters()
        for serial, meter in meters.items():
            print(f"Meter: {serial} ({meter['serviceType']})")


asyncio.run(main())

Browser OAuth Flow (Programmatic)

You can also integrate the OAuth flow into your own application:

import asyncio
import webbrowser
import aiohttp
from aiodukeenergy import Auth0Client, DukeEnergy, DukeEnergyAuth


async def main():
    async with aiohttp.ClientSession() as session:
        auth0_client = Auth0Client(session)
        auth = DukeEnergyAuth(session, auth0_client)

        # Step 1: Get authorization URL with PKCE
        auth_url, state, code_verifier = auth0_client.get_authorization_url()

        # Step 2: Open browser for user login
        webbrowser.open(auth_url)

        # Step 3: Get the authorization code (captured by Chrome extension)
        code = input("Enter the authorization code: ")

        # Step 4: Exchange code for tokens
        await auth.authenticate_with_code(code, code_verifier)

        # Now you can make API calls
        client = DukeEnergy(auth)
        accounts = await client.get_accounts()
        print(accounts)


asyncio.run(main())

Available Classes
