aiovantage

aiovantage is a Python library for interacting with and controlling Vantage InFusion home automation controllers.

Uses a controller pattern inspired heavily by the aiohue library.

This open-source, non-commercial library is not affiliated, associated, authorized, endorsed by, or in any way officially connected with Vantage, and is provided for interoperability purposes only.

Example

from aiovantage import Vantage

async with Vantage("192.168.1.2", "username", "password") as vantage:
    async for load in vantage.loads:
        print(f"{load.name} is at {load.level}%")

See the examples folder for more examples.

Features

• Uses Python asyncio for non-blocking I/O.
• Exposes "controllers" to make fetching and controlling various objects easy.
• Uses SSL connections by default, with automatic reconnection.
• Fetch objects lazily (with async for obj in controller).
• Alternatively, eager-fetch objects with controller.initialize.

Installation

Add aiovantage as a dependency to your project, or install it directly:

pip install aiovantage

Usage

Creating a client

Begin by importing the Vantage class:

from aiovantage import Vantage

The most convenient way to create a client is by using the async context manager:

async with Vantage("hostname", "username", "password") as vantage:
    # ...use the vantage client

Alternatively, you can manage the lifecycle of the client yourself:

from aiovantage import Vantage

vantage = Vantage("hostname", "username", "password")
# ...use the vantage client
vantage.close()

Querying objects

The Vantage class exposes a number of controllers, which can be used to query objects. Controllers can either be populated lazily (by using async for), or eagerly (by using controller.initialize()).

For example, to get a list of all loads:

async with Vantage("hostname", "username", "password") as vantage:
    async for load in vantage.loads:
        print(f"{load.name} is at {load.level}%")

Alternatively, you can use controller.initialize() to eagerly fetch all objects:

async with Vantage("hostname", "username", "password") as vantage:
    await vantage.loads.initialize()
    for load in vantage.loads:
        print(f"{load.name} is at {load.level}%")

If you aren't interested in the state of the objects, you can call controller.initialize(fetch_state=False) to slightly speed up the initialization:

async with Vantage("hostname", "username", "password") as vantage:
    await vantage.loads.initialize(fetch_state=False)
    for load in vantage.loads:
        print(f"{load.name}")

All controllers implement a django-like query interface, which can be used to filter objects. You can either query by matching attributes:

async with Vantage("hostname", "username", "password") as vantage:
    async for load in vantage.loads.filter(name="Kitchen"):
        print(f"{load.name} is at {load.level}%")

Or by using a filter predicate:

async with Vantage("hostname", "username", "password") as vantage:
    async for load in vantage.loads.filter(lambda load: load.level > 50):
        print(f"{load.name} is at {load.level}%")

Fetching a single object

You can fetch a single object by id, by calling controller.aget() or controller.get():

async with Vantage("hostname", "username", "password") as vantage:
    load = await vantage.loads.aget(118)
    print(f"{load.name} is at {load.level}%")

These functions also implement the same query interface as controller.filter() for querying by attributes or filter predicate:

async with Vantage("hostname", "username", "password") as vantage:
    load = await vantage.loads.aget(name="Kitchen")
    print(f"{load.name} is at {load.level}%")

Controlling objects

Most controllers expose a various methods for controlling the state of objects. The first parameter to these methods is always the vantage id of the object to control.

For example, to turn on a load:

async with Vantage("hostname", "username", "password") as vantage:
    load = await vantage.loads.aget(name="Study Lights")
    load.turn_on()

Subscribing to state changes

You can subscribe to state changes by using the controller.subscribe() method:

def on_load_state_change(event, load, data):
    print(f"{load.name} is at {load.level}%")

async with Vantage("hostname", "username", "password") as vantage:
    vantage.loads.subscribe(on_load_state_change)
    await vantage.loads.initialize()

Note that a subscription will only receive state changes for objects that have populated into the controller.
