python-kasa

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

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

Contributions in any form (adding missing features, reporting issues, fixing or triaging existing ones, improving the documentation, or device donations) are more than welcome!

Getting started

You can install the most recent release using pip:

pip install python-kasa

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

git clone https://github.com/python-kasa/python-kasa.git
cd python-kasa/
uv sync --all-extras
uv run kasa

If you have not yet provisioned your device, you can do so using the cli tool.

Discovering devices

Running kasa discover will send discovery packets to the default broadcast address (255.255.255.255) to discover supported devices. If your device requires authentication to control it, you need to pass the credentials using --username and --password options or define KASA_USERNAME and KASA_PASSWORD environment variables.

[!NOTE] If your system has multiple network interfaces, you can specify the broadcast address using the --target option.

The discover command will automatically execute the state command on all the discovered devices:

$ kasa discover
Discovering devices on 255.255.255.255 for 3 seconds

Command line usage

All devices support a variety of common commands (like on, off, and state). The syntax to control device is kasa --host <host> <command>:

$ kasa --host 192.0.2.123 on

Use kasa --help (or consult the documentation) to get a list of all available commands and options. Some examples of available options include JSON output (--json), more verbose output (--verbose), and defining timeouts (--timeout and --discovery-timeout). Refer the documentation for more details.

[!NOTE] Each individual command may also have additional options, which are shown when called with the --help option.

Feature interface

All devices are also controllable through a generic feature-based interface. The available features differ from device to device and are accessible using kasa feature command:

$ kasa --host 192.0.2.123 feature
== Primary features ==
State (state): False
Brightness (brightness): 11 (range: 0-100)
Color temperature (color_temperature): 0 (range: 2500-6500)

Smooth transition on (smooth_transition_on): 2 (range: 0-60)

SSID (ssid): HomeNet
Current firmware version (current_firmware_version): 1.1.6 Build 240130 Rel.173828
Available firmware version (available_firmware_version): None

Some features present configuration that can be changed:

kasa --host 192.0.2.123 feature color_temperature 2500
Changing color_temperature from 0 to 2500
New state: 2500

[!NOTE] When controlling hub-connected devices, you need to pass the device ID of the connected device as an option: kasa --host 192.0.2.200 feature --child someuniqueidentifier target_temperature 21

Library usage

import asyncio
from kasa import Discover

async def main():
    dev = await Discover.discover_single("192.0.2.123", username="un@example.com", password="pw")
    await dev.turn_on()
    await dev.update()

if __name__ == "__main__":
    asyncio.run(main())

If you want to use this library in your own project, a good starting point is the tutorial in the documentation.

You can find several code examples in the API documentation How to guides.

Information about the library design and the way the devices work can be found in the topics section.

Contributing

Contributions are very welcome! The easiest way to contribute is by creating a fixture file for the automated test suite if your device hardware and firmware version is not currently listed as supported. Please refer to our contributing guidelines.

Supported devices

The following devices have been tested and confirmed as working. If your device is unlisted but working, please consider contributing a fixture file.

[!NOTE] The hub attached Tapo buttons S200B and S200D do not currently support alerting when the button is pressed.
