samsungctl
==========

samsungctl is a library and a command line tool for remote controlling Samsung
televisions via a TCP/IP connection. It currently supports both pre-2016 TVs as
well most of the modern Tizen-OS TVs with Ethernet or Wi-Fi connectivity.

Dependencies
============

- Python 3
- ``websocket-client`` (optional, for 2016+ TVs)
- ``curses`` (optional, for the interactive mode)

Installation
============

samsungctl can be installed using `pip <(https://pip.pypa.io/>`_:

::

    # pip install samsungctl

Alternatively you can clone the Git repository and run:

::

    # python setup.py install

It's possible to use the command line tool without installation:

::

    $ python -m samsungctl

Command line usage
==================

You can use ``samsungctl`` command to send keys to a TV:

::

    $ samsungctl --host <host> [options] <key> [key ...]

``host`` is the hostname or IP address of the TV. ``key`` is a key code, e.g.
``KEY_VOLDOWN``. See `Key codes`_.

There is also an interactive mode (ncurses) for sending the key presses:

::

    $ samsungctl --host <host> [options] --interactive

Use ``samsungctl --help`` for more information about the command line
arguments:

::

    usage: samsungctl [-h] [--version] [-v] [-q] [-i] [--host HOST] [--port PORT]
                      [--method METHOD] [--name NAME] [--description DESC]
                      [--id ID] [--timeout TIMEOUT]
                      [key [key ...]]

    Remote control Samsung televisions via TCP/IP connection

    positional arguments:
      key                 keys to be sent (e.g. KEY_VOLDOWN)

    optional arguments:
      -h, --help          show this help message and exit
      --version           show program's version number and exit
      -v, --verbose       increase output verbosity
      -q, --quiet         suppress non-fatal output
      -i, --interactive   interactive control
      --host HOST         TV hostname or IP address
      --port PORT         TV port number (TCP)
      --method METHOD     Connection method (legacy or websocket)
      --name NAME         remote control name
      --description DESC  remote control description
      --id ID             remote control id
      --timeout TIMEOUT   socket timeout in seconds (0 = no timeout)

    E.g. samsungctl --host 192.168.0.10 --name myremote KEY_VOLDOWN

The settings can be loaded from a configuration file. The file is searched from
``$XDG_CONFIG_HOME/samsungctl.conf``, ``~/.config/samsungctl.conf``, and
``/etc/samsungctl.conf`` in this order. A simple default configuration is
bundled with the source as `samsungctl.conf <samsungctl.conf>`_.

Library usage
=============

samsungctl can be imported as a Python 3 library:

.. code-block:: python

    import samsungctl

A context managed remote controller object of class ``Remote`` can be
constructed using the ``with`` statement:

.. code-block:: python

    with samsungctl.Remote(config) as remote:
        # Use the remote object

The constructor takes a configuration dictionary as a parameter. All
configuration items must be specified.

===========  ======  ===========================================
Key          Type    Description
===========  ======  ===========================================
host         string  Hostname or IP address of the TV.
port         int     TCP port number. (Default: ``55000``)
method       string  Connection method (``legacy`` or ``websocket``)
name         string  Name of the remote controller.
description  string  Remote controller description.
id           string  Additional remote controller ID.
timeout      int     Timeout in seconds. ``0`` means no timeout.
===========  ======  ===========================================

The ``Remote`` object is very simple and you only need the ``control(key)``
method. The only parameter is a string naming the key to be sent (e.g.
``KEY_VOLDOWN``). See `Key codes`_. You can call ``control`` multiple times
using the same ``Remote`` object. The connection is automatically closed when
exiting the ``with`` statement.

When something goes wrong you will receive an exception:

=================  =======================================
Exception          Description
=================  =======================================
AccessDenied       The TV does not allow you to send keys.
ConnectionClosed   The connection was closed.
UnhandledResponse  An unexpected response was received.
socket.timeout     The connection timed out.
=================  =======================================

Example program
---------------

This simple program opens and closes the menu a few times.

.. code-block:: python

    #!/usr/bin/env python3

    import samsungctl
    import time

    config = {
        "name": "samsungctl",
        "description": "PC",
        "id": "",
        "host": "192.168.0.10",
        "port": 55000,
        "method": "legacy",
        "timeout": 0,
    }

    with samsungctl.Remote(config) as remote:
        for i in range(10):
            remote.control("KEY_MENU")
            time.sleep(0.5)

Key codes
=========

The list of accepted keys may vary depending on the TV model, but the following
list has some common key codes and their descriptions.

the only implementation. Here is the list of things that inspired samsungctl.
