## Documentation

See documentation at: [https://xknx.io/](https://xknx.io/)

## Help

We need your help for testing and improving XKNX. For questions, feature requests, bug reports either open an [issue](https://github.com/XKNX/xknx/issues), join the [XKNX chat on Discord](https://discord.gg/EuAQDXU) or write an [email](mailto:[email protected]).

## Development

You will need at least Python 3.10 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](https://home-assistant.io/).

## Example

```python

"""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',

        )

        xknx.devices.async_add(light)

        await light.set_on()

        await asyncio.sleep(2)

        await light.set_off()

asyncio.run(main())

```
