SAMSUNGCTL

BIG NEWS!!!! samsungctl now supports the ever elusive H and J model year (2014 and 2015) TV's

OK so first thing is first. I want to give a special thanks to the people that helped in the bug testing of this version. It has been a bit of a challenge because of the different devices/OS's that samsungctl is running on. In no special order I want to say TY for the help. If I have missed mentioning ya. let me know. That was one really long issue thread. and Github likes to collapse the thing. I could have missed expanding one or 2 of the sections.

Onto the library.

samsungctl is a library and a command line tool for remote controlling Samsung televisions via a TCP/IP connection. It currently supports both pre-2014 and 2016+ TVs as well most of the modern Tizen-OS TVs with Ethernet or Wi-Fi connectivity.

UPDATE: This library supports 2016+ TV's running the latest firmware. Samsung has changed it's websocket connection to now use SSL encryption. We have this all sorted out.

If the TV kicks back an error when connecting the program will then try the SSL connection. The SSL connection uses a token based system. What this means is, there will be only one thing you need to do if your TV uses this kind of a connection. You will get a message on the TV to pair a remote. You will need to click on the "Accept" button. You have 30 seconds to do this before the program will error out.

There is a flat text file that is used to store the token between uses of the program. This is so that you will not have to go through the above process each and every time you use the program. This file is going to be different for each user that can be logged into the computer.micro controller.

On NIX systems the file is stored in ~/.samsungctl

On Windows the file is stored in %appdata%\samsungctl

Both of the locations are specific to the profile of the user that is logged in. I placed the file in these locations as to avoid any permissions related issues.

This program IS NOT the same one that is available on the Python Packaging Index (Pypi). I do not have access to that and unfortunatly the original author Ape has been on hiatus for some time. He may no longer be maintaining the library.

So for the time being you will need to clone this repository and install it using the directions below.

More Changes:

Python 2.7+ compatible Better logging Adds additional keycodes (A LOT) The websocket-client library a requirement not an option

Things to come Expanded control and notifications from the TV Automatic discovery of the TV Support for other Samsung devices

Dependencies

Python 2.7+
websocket-client
curses (optional, for the interactive mode)

Installation

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]

--key-help {OPTIONAL KEYS}	prints out key help

samsungctl --host 192.168.0.10 --name myremote KEY_VOLDOWN

To obtain a list of all of the known keys. samsungctl --help-keys

You can also get help on a specific key samsungctl --key-help KEY_16_9

or if you wanted to list more then one key samsungctl --key-help KEY_16_9 KEY_TTX_MIX

The settings can be loaded from a configuration file. The file is searched from

$XDG_CONFIG_HOME/samsungctl.conf
~/.config/samsungctl.conf
/etc/samsungctl.conf

in this order. A simple default configuration is bundled with the source as

samsungctl.conf <samsungctl.conf>

--config-file

This is how the --config-file parameter works. If this is the first time you are using this library on a TV you must specify --method and --host and key code for the command you wish to execute along with this parameter. By doing this is will make all of the necessary config file settings that are needed to be made for your TV. After the library has sent the command to your TV it will then save the file. Any calls there after will only need to have --config-file PATH/FILENAME along with the command you wish to perform for a command line options. All other information will be retrieved from the file.

Library usage

samsungctl can also be used as a python package.

    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

Config Class

Depreciated 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.
token	string	Authentication token
timeout	int	Timeout in seconds. `0` means no timeout.

I have put into place a class that handlees all of thee configuration information. It makes it easier for saving and loading confiig data.

import samsungctl


config = samsungctl.Config(
    name='samsungctl',
    description='samsungctl-library',
    method='websocket',
    port=8001
)

The constrictor for the Config class takes these parameters

Param Name	Default value	Use
name	None	Name of the "remote" this is the name that is going to appear on the TV
description	None	Only used in the legacy connection (pre 2014 TVs)
host	None	The ip address of the TV
port	None	The port to connect to. choices aree 55000 (< 2014), 8080 (2014 & 2015), 8001 & 8002 (>= 2016)
method	None	The connection method. legacy, websocket or encrypted
id	None	This is an identifier that you can set. when using the "encrypted" method this should be left out
timeout	0	socket timeout, only used for the legacy method
token	None	Authentication token that is used for 2014 & 2015 and some 2016+ TV's
device_id	None	Internal Use
upnp_locations	None	Future Use

the Config class is also where you set your logging level

import logging
import samsungctl


config = samsungctl.Config(
    name='samsungctl',
    method='websocket',
    host='192.168.1.100'
)

config.log_level = logging.DEBUG

There are 2 nice convenience methods for saving and loading a config file.

import samsungctl

config = samsungctl.Config.load('path/to/save/file')

If you load a file the path is saved so you can simply call save to save any new data. If you constructed the Config class manually you will need to pass a path when calling save. and that path is then saved so any subsequent calls to save will not require you to pass thee path

import samsungctl


config = samsungctl.Config(
    name='samsungctl',
    description='samsungctl-library',
    method='websocket',
    host='192.168.1.100'
)

config.save('path/to/save/file')

when calling save if you pass only a folder path and not a folder/file path the name you passed to the constructor will be useed along with the extension ".config"

You do not need to keep track of the config instance. once it is passed to the Remote constructor it is then stored in that instance.

import samsungctl


config = samsungctl.Config.load('path/to/save/file')
remote = samsungctl.Remote(config)
remote.config.save()

You are still able to pass a dictionary to the Remote constructor as well.

The only parameters you MUST supply is the method and the host. everything else has a default value associated with it.

Power Property

I also added power status along with powering off and on 2014+ TV's

import samsungctl


config = samsungctl.Config.load('path/to/save/file')
remote = samsungctl.Remote(config)
print(remote.power)

# turns the TV on
remote.power = True

print(remote.power)
# turns the TV off
remote.power = False

# toggles the power
remote.power = not remote.power

We do not have the ability to turn on the TV's older then 2014.

Exceptions

When something goes wrong you will receive an exception:

Exception	Description
SamsungTVError	Samsung TV Exception Base Class.
AccessDenied	Connection was denied.
ConnectionClosed	Connection was closed.
UnhandledResponse	Received unknown response.
NoTVFound	Unable to locate a TV.
ConfigError	Base class for config exceptions.
ConfigUnknownMethod	Unknown connection method.
ConfigParseError	Config data is not json formatted or is not a formatted flat file.
ConfigLoadError	Config path specified cannot be located.
ConfigSavePathError	Config save path is not valid.
ConfigSaveError	Error saving config.
ConfigSavePathNotSpecified	Config save path was not specified.
ConfigParameterError	Parameter is not a config parameter.

Example program

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

import samsungctl
import time

config = samsungctl.Config(
    name='samsungctl',
    method='legacy',
    host='192.168.1.100'
)

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

Mouse Control

Mouse control can only be done by using samsungctl as a python module. Mouse command are built. this way you can accomplish multiple movements in a single "command" and the movement set can be stored for later use. depending on how long it takes to accomplish a movement (distance traveled) you will need to insert a wait period in between each movement.

import samsungctl

config = samsungctl.Config(
    name='samsungctl',
    method='websocket',
    host='192.168.1.100'
)

with samsungctl.Remote(config) as remote:
    mouse = remote.mouse
    mouse.move(x=100, y=300)
    mouse.wait(0.5)
    mouse.left_click()
    mouse.run()
    mouse.clear()

I designed this to all be thread safe. so only one mouse command set can be run at a single time. So if you have the mouse running in a thread and you need to stop the movement from another. or you simply want to terminate the program gracefully. you would call mouse.stop()

I will be at a later date adding the wait periods on the mouse movements so it will be done automatically. I do not own one of the TV's so I do not know how long it takes to move the mouse different distances. I also do not know if the time it takes to move the mouse is linear. An example of linear movement would be it takes 1 second to move the mouse 100 pixels so to move it 200 pixels it would take 2 seconds. most devices that have mouse control also have acceleration and a min/max speed which would be non linear movement. An example of non linear is, if it took 1 second to move the mouse 100 pixels, to move it 200 it would take 1.5 seconds. You can run the code below and report the output to me. that will aide in making this all automatic. I need this data form several TV models and years. as Samsung could have changed the mouse speed and acceleration between years/models.

import samsungctl
import time


config = samsungctl.Config(
    name='samsungctl',
    method='websocket',
    host='192.168.1.100'
)

with samsungctl.Remote(config) as remote:
     mouse = remote.mouse

    def move_mouse(_x, _y):
        mouse.move(x=x, y=y)
        start = time.time()
        mouse.run()
        stop = time.time()
        print('x:', x, 'y:', y, 'time:', (stop - start) * 1000)
        mouse.clear()
        mouse.move(x=-x, y=-y)
        mouse.run()
        mouse.clear()

    for x in range(1920):
        move_mouse(x, 0)

        for y in range(1080):
            move_mouse(0, y)
            move_mouse(x, y)

Voice Recognition

If you TV supports voice recognition you have the ability to start and stop the voice recognition service on the TV. this can be done only by using the samsungctl library as a package to an already existing program. example code of how to do this is below.

import samsungctl
import time

config = samsungctl.Config(
    name='samsungctl',
    method='websocket',
    host='192.168.1.100'
)

with samsungctl.Remote(config) as remote:
    remote.start_voice_recognition()
    time.sleep(5.0)
    remote.stop_voice_recognition()

Applications

This is going to be a wee bit long winded. But here goes

below is a sample of how to access the applications on the TV

import samsungctl

config = samsungctl.Config(
    name='samsungctl',
    method='websocket',
    host='192.168.1.100'
)

with samsungctl.Remote(config) as remote:
    for app in remote.applications:
        print('name:', app.name)
        print('=' * 30)
        print('id:', app.app_id)
        print('is running:', app.is_running)
        print('version:', app.version)
        print()

if you want to access a specific application by name or by the app id

import samsungctl

config = samsungctl.Config(
    name='samsungctl',
    method='websocket',
    host='192.168.1.100'
)

with samsungctl.Remote(config) as remote:
    app = remote.get_application('YouTube')
    if app is not None:
        print('name:', app.name)
        print('=' * 30)
        print('id:', app.app_id)
        print('is running:', app.is_running)
        print('version:', app.version)
        print()

these are the available properties for an application

is_lock
name
app_type
position
app_id
launcher_type
mbr_index
source_type_num
icon
id
mbr_source
action_type
version
is_visible
is_running

now here is a little bonus. we can also iterate over an application for any content groups. and then we can iterate over the content group for the available content in that group

import samsungctl

config = samsungctl.Config(
    name='samsungctl',
    method='websocket',
    host='192.168.1.100'
)

with samsungctl.Remote(config) as remote:
    for app in remote.applications:
        print('name:', app.name)
        print('=' * 30)
        for content_group in app:
            print('   ', content_group.title)
            print('   ', '-' * 26)
            for content in content_group:
                print('       ', content.title)

here are the available properties for the content group

title

here are the available properties for the content

is_playable
subtitle
app_type
title
mbr_index
live_launcher_type
action_play_url
service_id
launcher_type
source_type_num
action_type
app_id
subtitle2
display_from
display_until
mbr_source
id
subtitle3
icon

You can also run an application or a piece of content by calling run() on either an application or on the content.

Please note that some codes are different on the 2016+ TVs. For example, KEY_POWEROFF is KEY_POWER on the newer TVs.

I also added all of th keys as methods. so you havee the choice of using the method for sending a key

import samsungctl

config = samsungctl.Config(
    name='samsungctl',
    method='websocket',
    host='192.168.1.100'
)

with samsungctl.Remote(config) as remote:
    remote.command("KEY_VOLUP")

or you can also use this

import samsungctl

config = samsungctl.Config(
    name='samsungctl',
    method='websocket',
    host='192.168.1.100'
)

with samsungctl.Remote(config) as remote:
    remote.KEY_VOLUP()

References

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.
