XKNX - An asynchronous KNX library written in Python

Documentation

See documentation at: https://xknx.io/

Help

We need your help for testing and improving XKNX. For questions, feature requests, bug reports either open an issue, join the XKNX chat on Discord or write an email.

Development

You will need at least Python 3.9 in order to use XKNX.

Setting up your local environment:

1. Install requirements: pip install -r requirements/testing.txt
2. Install pre-commit hook: pre-commit install

Testing

To run all tests, linters, formatters and type checker call tox

Running only unit tests is possible with pytest Running specific unit tests can be invoked by: pytest -vv test/management_tests/procedures_test.py -k test_nm_individual_address_serial_number_write_fail

Home-Assistant

XKNX is the underlying library for the KNX integration in Home Assistant.

Example

"""Example for switching a light on and off."""
import asyncio

from xknx import XKNX
from xknx.devices import Light


async def main():
    """Connect to KNX/IP bus, switch on light, wait 2 seconds and switch it off again."""
    async with XKNX() as xknx:
        light = Light(xknx,
                      name='TestLight',
                      group_address_switch='1/0/9')
        await light.set_on()
        await asyncio.sleep(2)
        await light.set_off()

asyncio.run(main())
