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:

# 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.

Library usage

samsungctl can be imported as a Python 3 library:

import samsungctl

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

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.

#!/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.

Key code Description
KEY_POWEROFF Power off
KEY_UP Up
KEY_DOWN Down
KEY_LEFT Left
KEY_RIGHT Right
KEY_CHUP P Up
KEY_CHDOWN P Down
KEY_ENTER Enter
KEY_RETURN Return
KEY_CH_LIST Channel List

I did not reverse engineer the control protocol myself and samsungctl is not the only implementation. Here is the list of things that inspired samsungctl.
