aiostreammagic

An async python package for interfacing with Cambridge Audio / Stream Magic compatible streamers

About

This module implements a Python client for the Stream Magic API used to control Cambridge Audio streamers. The API connects over TCP/IP and supports several streamers, receivers, and pre-amps.

Supported Devices

• Cambridge Audio Evo 75
• Cambridge Audio Evo 150
• Cambridge Audio CXN
• Cambridge Audio CXN (v2)
• Cambridge Audio CXR120
• Cambridge Audio CXR200
• Cambridge Audio 851N
• Cambridge Audio Edge NQ

If your model is not on the list of supported devices, and everything works correctly then add it to the list by opening a pull request.

Installation

pip install aiostreammagic

Examples

Basic Example

import asyncio

from aiostreammagic import StreamMagicClient, Source, Info

HOST = "192.168.20.218"


async def main():
    """Basic demo entrypoint."""
    client = StreamMagicClient("192.168.20.218")
    await client.connect()

    info: Info = await client.get_info()
    sources: list[Source] = await client.get_sources()

    print(f"Model: {info.model}")
    for source in sources:
        print(f"Name: {source.id} ({source.id})")

    await client.disconnect()

if __name__ == '__main__':
    asyncio.run(main())

Subscription Example

The Cambridge Audio StreamMagic API can automatically notify the client of changes instead of the need for polling. Register a callback to be called whenver new information is available.

import asyncio

from aiostreammagic import StreamMagicClient

HOST = "192.168.20.218"


async def on_state_change(client: StreamMagicClient):
    """Called when new information is received."""
    print(f"System info: {client.get_info()}")
    print(f"Sources: {client.get_sources()}")
    print(f"State: {client.get_state()}")
    print(f"Play State: {client.get_play_state()}")
    print(f"Now Playing: {client.get_now_playing()}")

async def main():
    """Subscribe demo entrypoint."""
    client = StreamMagicClient("192.168.20.218")
    await client.register_state_update_callbacks(on_state_change)
    await client.connect()

    # Play media using the unit's front controls or StreamMagic app
    await asyncio.sleep(60)

    await client.disconnect()


if __name__ == '__main__':
    asyncio.run(main())
