PyWebOSTV

Why another Library?

I looked at a few libraries. The LGWebOSRemote repository by klattimer is definitely a good library, but it has a few problems:

• Meant to be used with Python 2.x.
• Assumes all the users of the library would like to save the credentials to ~/.lgtv.json.
• Assumes only a single command will be fired and waited on at any given time (ctrl+F for self.__waiting_callback)
• Mouse/Keyboard not supported.

This SDK is a tiny attempt at overcoming some of the above problems.

Current status?

At the moment, I haven't been able to do any kind of extensive testing. No unit test cases too! Current status: Works for quite a few people! :)

Currently working on more controls and unit test cases. Upon testing, I will upload it to PyPI.

How to use it?

from pywebostv.discovery import *
from pywebostv.connection import *
from pywebostv.controls import *

# The 'store' gets populated during the registration process. If it is 
# empty, a registration prompt will show up on the TV. You can pass any
# dictionary-like interface instead -- that when values are set, will 
# persist to a DB, a config file or something similar.
store = {}

# Scans the current network to discover TV. Avoid [0] in real code.
# If you already know the IP, you could skip the slow scan and 
# instead simply say:
#    client = WebOSClient("<IP Address of TV>")
client = WebOSClient.discover()[0]
client.connect()
for status in client.register(store):
    if status == WebOSClient.PROMPTED:
        print("Please accept the connect on the TV!")
    elif status == WebOSClient.REGISTERED:
        print("Registration successful!")

Media Controls

media = MediaControl(client)
media.volume_up()
media.volume_down()
media.get_volume()
media.set_volume(<int>)
media.mute(<mute status as boolean>)
media.play()
media.pause()
media.stop()
media.rewind()
media.fast_forward()

System Controls

system = SystemControl(client)
system.notify("This is a notification message!")
system.power_off()
system.info()

Application Controls

app = ApplicationControl(client)
apps = app.list_apps()
launch_info = app.launch(apps[0], content_id="...", params=...)
app.close(launch_info)

Mouse and Button Controls

You need to execute the first two commands.

inp = InputControl(client)
inp.connect_input()
inp.move(10, 10) # Moves mouse
inp.click()
inp.up()
inp.down()
inp.left()
inp.right()
inp.home()
inp.back()

# Following 3 lines are valid only when an input field is focussed on TV.
inp.type("This sends keyboard input!")
inp.enter()  # Return key.
inp.delete(10)  # Backspace 10 chars

inp.disconnect_input()

TV Controls

tv_control = TvControl()
tv_control.channel_down()
tv_control.channel_up()

Source Controls

source_control = SourceControl(client)
sources = source_control.list_sources()
source_control.set_source(sources[0])

More controls coming soon!

Credits

• klattimer for his library! Since WebOS team decided against providing any sort of documentation, his repository was extremely useful for an initial implementation
• As far as input controls are concerned, they are based on the Java package written by Connect-SDK folks!
