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)

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.
