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
```
For enhanced cli tool support (coloring, embedded shell) install with `[shell]`:
```
pip install python-kasa[shell]
```
If you are using cpython, it is recommended to install with `[speedups]` to enable orjson (faster json support):
```
pip install python-kasa[speedups]
```
or for both:
```
pip install python-kasa[speedups, shell]
```
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 https://github.com/python-kasa/python-kasa.git
cd python-kasa/
poetry install
```
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 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

```
If your device requires authentication to control it,
you need to pass the credentials using `--username` and `--password` options.
## Basic functionalities
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
The syntax to control device is `kasa --host `.
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`), defining timeouts (`--timeout` and `--discovery-timeout`).
Each individual command may also have additional options, which are shown when called with the `--help` option.
For example, `--transition` on bulbs requests a smooth state change, while `--name` and `--index` are used on power strips to select the socket to act on:
```
$ kasa on --help
Usage: kasa on [OPTIONS]
Turn the device on.
Options:
--index INTEGER
--name TEXT
--transition INTEGER
--help Show this message and exit.
```
### Bulbs
Common commands for bulbs and light strips include:
* `brightness` to control the brightness
* `hsv` to control the colors
* `temperature` to control the color temperatures
When executed without parameters, these commands will report the current state.
Some devices support `--transition` option to perform a smooth state change.
For example, the following turns the light to 30% brightness over a period of five seconds:
```
$ kasa --host brightness --transition 5000 30
```
See `--help` for additional options and [the documentation](https://python-kasa.readthedocs.io/en/latest/smartbulb.html) for more details about supported features and limitations.
### Power strips
Each individual socket can be controlled separately by passing `--index` or `--name` to the command.
If neither option is defined, the commands act on the whole power strip.
For example:
```
$ kasa --host off # turns off all sockets
$ kasa --host off --name 'Socket1' # turns off socket named 'Socket1'
```
See `--help` for additional options and [the documentation](https://python-kasa.readthedocs.io/en/latest/smartstrip.html) for more details about supported features and limitations.
## Energy meter
Running `kasa emeter` command will return the current consumption.
Possible options include `--year` and `--month` for retrieving historical state,
and reseting the counters can be done with `--erase`.
```
$ kasa emeter
== Emeter ==
Current state: {'total': 133.105, 'power': 108.223577, 'current': 0.54463, 'voltage': 225.296283}
```
# Library usage
If you want to use this library in your own project, a good starting point is to check [the documentation on discovering devices](https://python-kasa.readthedocs.io/en/latest/discover.html).
You can find several code examples in the API documentation of each of the implementation base classes, check out the [documentation for the base class shared by all supported devices](https://python-kasa.readthedocs.io/en/latest/smartdevice.html).
[The library design and module structure is described in a separate page](https://python-kasa.readthedocs.io/en/latest/design.html).
The device type specific documentation can be found in their separate pages:
* [Plugs](https://python-kasa.readthedocs.io/en/latest/smartplug.html)
* [Bulbs](https://python-kasa.readthedocs.io/en/latest/smartbulb.html)
* [Dimmers](https://python-kasa.readthedocs.io/en/latest/smartdimmer.html)
* [Power strips](https://python-kasa.readthedocs.io/en/latest/smartstrip.html)
* [Light strips](https://python-kasa.readthedocs.io/en/latest/smartlightstrip.html)
## Contributing
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](https://python-poetry.org) 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
```
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](https://github.com/softScheck/tplink-smartplug#wireshark-dissector)
or the `parse_pcap.py` script contained inside the `devtools` directory.
Note, that this works currently only on kasa-branded devices which use port 9999 for communications.
## Supported devices
The following devices have been tested and confirmed as working. If your device is unlisted but working, please open a pull request to update the list and add a fixture file (use `python -m devtools.dump_devinfo` to generate one).

### TP-Link Tapo support
This library has recently added a limited supported for devices that carry Tapo branding.
That support is currently limited to the cli. The package `kasa.smart` is in flux and if you
use it directly you should expect it could break in future releases until this statement is removed.
