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](https://python-kasa.readthedocs.io/en/latest/cli.html#provisioning).

## 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](https://python-kasa.readthedocs.io/en/latest/cli.html#kasa-help)) 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](https://python-kasa.readthedocs.io/en/latest/cli.html) 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)
Light effect (light_effect): *Off* Party Relax

== Information ==
Signal Level (signal_level): 2
Overheated (overheated): False
Cloud connection (cloud_connection): False
Update available (update_available): None
Device time (device_time): 2024-06-22 15:39:44+02:00

== Configuration ==
HSV (hsv): HSV(hue=35, saturation=70, value=11)
Auto update enabled (auto_update_enabled): False
Light preset (light_preset): *Not set* Light preset 1 Light preset 2 Light preset 3 Light preset 4 Light preset 5 Light preset 6 Light preset 7
Smooth transition on (smooth_transition_on): 2 (range: 0-60)
Smooth transition off (smooth_transition_off): 20 (range: 0-60)

== Debug ==
Device ID (device_id): soneuniqueidentifier
RSSI (rssi): -50 dBm
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](https://python-kasa.readthedocs.io/en/latest/tutorial.html).

You can find several code examples in the API documentation [How to guides](https://python-kasa.readthedocs.io/en/latest/guides.html).

Information about the library design and the way the devices work can be found in the [topics section](https://python-kasa.readthedocs.io/en/latest/topics.html).

## Contributing

Contributions are very welcome! The easiest way to contribute is by [creating a fixture file](https://python-kasa.readthedocs.io/en/latest/contribute.html#contributing-fixture-files) for the automated test suite if your device hardware and firmware version is not currently listed as supported.
Please refer to [our contributing guidelines](https://python-kasa.readthedocs.io/en/latest/contribute.html).

## 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](https://python-kasa.readthedocs.io/en/latest/contribute.html#contributing-fixture-files).

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

> [!NOTE]
> Some firmware versions of Tapo Cameras will not authenticate unless you enable "Tapo Lab" > "Third-Party Compatibility" in the native Tapo app.
> Alternatively, you can factory reset and then prevent the device from accessing the internet.
