python-kasa/kasa/__init__.py

"""Python interface for TP-Link's smart home devices.

All common, shared functionalities are available through `Device` class::

>>> from kasa import Discover
>>> x = await Discover.discover_single("192.168.1.1")
>>> print(x.model)

For device type specific actions `modules` and `features` should be used instead.

Module-specific errors are raised as `KasaException` and are expected
to be handled by the user of the library.
