PyPI version Build Status codecov Documentation Status

python-kasa is a Python library to control TPLink’s kasa-branded smart home devices (plugs, wall switches, power strips, and bulbs) using asyncio.

This is a voluntary, community-driven effort and is not affiliated, sponsored, or endorsed by TPLink.

Getting started

You can install the most recent release using pip:

pip install python-kasa

If you are using cpython, it is recommended to install with [speedups] to enable orjson (faster json support):

pip install python-kasa[speedups]

With [speedups], the protocol overhead is roughly an order of magnitude lower (benchmarks available in devtools).

Alternatively, you can clone this repository and use poetry to install the development version:

git clone
cd python-kasa/
poetry install

Discovering devices

After installation, the devices can be discovered either by using kasa discover or by calling kasa without any parameters.

$ kasa

Use kasa --help to get list of all available commands, or alternatively, consult the documentation.

Basic controls

All devices support a variety of common commands, including:

  • state which returns state information

  • on and off for turning the device on or off

  • emeter (where applicable) to return energy consumption information

  • sysinfo to return raw system information

Energy meter

Passing no options to emeter command will return the current consumption. Possible options include --year and --month for retrieving historical state, and reseting the counters is done with --erase.

$ kasa emeter
== Emeter ==
Current state: {'total': 133.105, 'power': 108.223577, 'current': 0.54463, 'voltage': 225.296283}

Bulb-specific commands

At the moment setting brightness, color temperature and color (in HSV) are supported depending on the device. The commands are straightforward, so feel free to check --help for instructions how to use them.

Library usage

You can find several code examples in the API documentation.


Contributions are very welcome! To simplify the process, we are leveraging automated checks and tests for contributions.

Setting up development environment

To get started, simply clone this repository and initialize the development environment. We are using poetry for dependency management, so after cloning the repository simply execute poetry install which will install all necessary packages and create a virtual environment for you.

Code-style checks

We use several tools to automatically check all contributions. The simplest way to verify that everything is formatted properly before creating a pull request, consider activating the pre-commit hooks by executing pre-commit install. This will make sure that the checks are passing when you do a commit.

You can also execute the checks by running either tox -e lint to only do the linting checks, or tox to also execute the tests.

Running tests

You can run tests on the library by executing pytest in the source directory. This will run the tests against contributed example responses, but you can also execute the tests against a real device:

pytest --ip <address>

Note that this will perform state changes on the device.

Analyzing network captures

The simplest way to add support for a new device or to improve existing ones is to capture traffic between the mobile app and the device. After capturing the traffic, you can either use the softScheck’s wireshark dissector or the script contained inside the devtools directory.

Supported devices

In principle all devices that are locally controllable using the official Kasa mobile app should work with this library. The following lists merely the devices that have been manually verified to work. If your device is unlisted but working, please open a pull request to update the list and add a fixture file (generated by devtools/
