If you are writing a personal Python script, Home Assistant integration, or Raspberry Pi automation, you can fetch your data directly without setting up a complex OAuth application.

​
Prerequisites

You do not need to generate API keys for this. You will use your standard iON email and password that you use to log into the consumer app.

​
The Script

Copy the Python script below. It uses our public DIY Client ID to automatically authenticate your account and fetch a 1-hour id_token to use for API requests.
Security Note: Because this script uses your real username and password, it should only be used in secure, local environments (like your own Raspberry Pi). Never put this script on a public web server.
Python
import requests

# 1. Your iON Credentials
USERNAME = "your_email@example.com"
PASSWORD = "Your_Password_123!"

# iON's Public Client ID for DIY Scripts
CLIENT_ID = "69gs8v1eli5or9167l7t7t84ef"

# 2. Authenticate with AWS Cognito to get a token
print("Authenticating...")
auth_response = requests.post(
    "https://cognito-idp.eu-central-1.amazonaws.com/",
    headers={
        "X-Amz-Target": "AWSCognitoIdentityProviderService.InitiateAuth",
        "Content-Type": "application/x-amz-json-1.1"
    },
    json={
        "AuthFlow": "USER_PASSWORD_AUTH",
        "ClientId": CLIENT_ID,
        "AuthParameters": {
            "USERNAME": USERNAME,
            "PASSWORD": PASSWORD
        }
    }
)

if auth_response.status_code != 200:
    print("Login Failed:", auth_response.json())
    exit()

# Extract the Token
id_token = auth_response.json()["AuthenticationResult"]["IdToken"]
print("Successfully obtained Bearer Token!")

# 3. Call the iON API
print("Fetching Telemetry Data...")
api_response = requests.get(
    "https://api.ionelectricity.com/v1/telemetry",
    headers={"Authorization": f"Bearer {id_token}"}
)

print(api_response.json())
