Welcome to OpenLEADR

A friendly and compliant OpenADR implementation for Python 3.

Key Features

  • Fully compliant OpenADR 2.0b implementation for both servers (Virtual Top Node) and clients (Virtual End Node)

  • Fully asyncio: you set up the coroutines that can handle certain events, and they get called when needed.

  • Fully pythonic: all messages are represented as simple Python dictionaries. All XML parsing and generation is done for you.

Library Installation

$ pip install openleadr

OpenLEADR is compatible with Python 3.7 and higher.

Getting Started

Client example:

from openleadr import OpenADRClient
import asyncio

async def main():
    client = OpenADRClient(ven_name="Device001",
    client.add_handler('on_event', handle_event)
    await client.run()

async def handle_event(event):
    This coroutine will be called
    when there is an event to be handled.
    print("There is an event!")
    # Do something to determine whether to Opt In or Opt Out
    return 'optIn'

loop = asyncio.get_event_loop()

This will connect to an OpenADR server (indicated by the vtn_url parameter), handle registration, start polling for events and reports, and will call your coroutines whenever an event or report is created for you.

Representations of OpenADR payloads

OpenLEADR uses Python dictionaries and vanilla Python types (like datetime and timedelta) to represent the OpenADR payloads. These pages serve as a reference to these representations.

For example, this XML payload:

<?xml version="1.0" encoding="utf-8"?>
<oadrPayload xmlns="http://openadr.org/oadr-2.0b/2012/07">
    <oadrResponse ei:schemaVersion="2.0b" xmlns:ei="http://docs.oasis-open.org/ns/energyinterop/201110">
        <requestID xmlns="http://docs.oasis-open.org/ns/energyinterop/201110/payloads" />

is represented in OpenLEADR as:

{'response': {'response_code': 200,
              'response_description': 'OK'},
 'ven_id': 'o57b65be83'}
