Alexa-LG-TV-Controller

Makes use of Klattimer's LGWebOSRemote module and Sinric's faux WEEMOS creator to control any smart LG TV with Alexa. This python script monitors Alexa's commands through Sinric, and then executes it using LG's nodejs API. It will allow you to turn on/off an LG tv and much more ... all from your Alexa device.

Supported models

Tested with

  • UF830V
  • UH650V
  • UJ635V

Setup

Requires wakeonlan, websocket and websocket-client for python and arp (in Debian/Ubuntu: apt-get install net-tools)

There's a requirements.txt included

 1.)  Setup your sinric account at https://sinric.com/
 2.)  Login to your account and click add smart home device, give the device a name and choose TV as device type
 ----> it is good at this point to copy the api of the device 
 3.)  On the Alexa app go to 'skills & games' and install sinric's skill and login to your account
 4.)  The fake device you just created on the website should then be seen in the Alexa app under 'devices'

# Now enter the directory with the files and type in command line 
------------------------------------->
1.)  pip install -r requirements.txt
2.)  sudo python setup.py
------------------------------------->
---> This will scan for your LG tv and will show the IP address of all LG tv's on the local network
# Example :
{
"count": 1, 
"list": [
    {
        "address": "192.168.0.158", 
        "model": "OLEDXXXXX", 
        "uuid": "0b6405648-ccc7-ab45f-967d-8gd47f21346"
    }
], 
"result": "ok"
}
---> You will then be prompted to enter the ip address of the TV you want to authorise on
please enter  ip like '192.168.0.158' (make sure to use brackets)
3.)  Enter IP address of TV, and a notification will pop up on the TV screen (click authorise on TV)

4.)  Now open the Alexa.py file and edit line 80. Here you need to replace :
# Example :
line 80 | api = ' enter-api-here  ' 
becomes 
line 80 | api = '65a23cd9-2e5d-495c-b4bd-5abfgh3l60345'

5.)  The final step is to start the Alexa.py file : 
          sudo python Alexa.py
     or to run in the background once terminal closes. Use: 
          sudo chmod +x Alexa.py
          nohup python /full/path/to/Alexa.py &
          logout

FeLiNa

Once all the steps above have been completed, and the python script is running, try telling your Alexa device to change your tv volume by saying

ALEXA SET (Sinric Device Name) VOLUME TO (intended level)

Caveats

You need to run setup.py whilst the TV is on as it will need to pull the mac address of the device.
