Samsung / Tizen TV API v2 - Joep - 24.02.2023

Hello,

I found this Python script to control a Samsung Smart TV.
Can someone help me to modify this Python script to a Lua script?
Source: https://github.com/vrachieru/samsung-tv-api/blob/master/samsungtv/remote.py

Thanks in advance.

This API uses websocket/JSON. You can use this example as a starting point: https://forum.logicmachine.net/showthread.php?tid=2185&pid=16331#pid16331

Got this so far but i'm strugling with the payload. What's the correct way to send the commands?

Code:
host = '192.168.126.54'

port = 8001

name = 'SamsungTvRemote'

if not client then

  ws = require('user.websocket')

  json = require('json')

  url = 'ws://'..host..':'..port..'/api/v2/channels/samsung.remote.control?name='..name

  client, err = ws.client('sync', 10)

  res, err = client:connect(url)

    log( res, err)

  if res then

    client:send(json.encode({

      payload = [[

        'method': 'ms.remote.control',

              'params': {

                    'Cmd': 'Click',

                    'DataOfCmd': key,

                    'Option': 'false',

                    'TypeOfRemote': 'SendRemoteKey'

                }

              ]]

    })) 

    client:send(json.encode({

      payload = [['KEY_VOLUP']]

    }))

  else

    log('connection failed: ' .. tostring(err))

    client:close()

    client = nil

  end

else

  data, _, _, opcode, err = client:receive()

  if data then

    data = json.pdecode(data)

    if data then

      log(data)

    end

  else

    log('receive failed: ' .. tostring(err))

    client:close()

    client = nil

  end

end

Hi Joep,
have you tried with API cloud?
best regards Cristian

RE: Samsung / Tizen TV API v2 - admin - 27.02.2023

Try this:

Code:
host = '192.168.126.54'

port = 8001

name = 'SamsungTvRemote'

b64 = require('encdec').base64enc

ws = require('user.websocket')

json = require('json')

url = 'ws://' .. host .. ':' .. port .. '/api/v2/channels/samsung.remote.control?name=' .. b64(name)

client, err = ws.client('sync', 10)

res, err = client:connect(url)

if not res then

  log('connection failed', err)

  return

end

data, _, _, opcode, err = client:receive()

resp = json.pdecode(data)

if type(resp) ~= 'table' or resp.event ~= 'ms.channel.connect' then

  log('invalid response', data, err)

  client:close()

  return

end

key = 'KEY_VOLUP'

payload = json.encode({

  method = 'ms.remote.control',

  params = {

    Cmd = 'Click',

    DataOfCmd = key,

    Option = 'false',

    TypeOfRemote = 'SendRemoteKey'

  }

})

client:send(payload)

client:close()

RE: Samsung / Tizen TV API v2 - Joep - 27.02.2023

It's not working as i got an 'unautorized' reply. I know you first need to submit each remote control by a popup that appears a the the tv screen.

So for that i just tested with a basic url:
url = 'ws://' .. host .. ':' .. port .. '/api/v2/'

And then i got this response:
Samsung TV websocket 27.02.2023 14:08:28
* table:
["data"]
* table:
["clients"]
* table:
[1]
* table:

The same url http://192.168.126.54:8001/api/v2/ in the webbrowser is giving me more information back:

RE: Samsung / Tizen TV API v2 - admin - 27.02.2023

It seems that you need to send KEY_HOME first to get the access token. Then add this token to the query string for further calls: ...samsung.remote.control?name=NAME&token=TOKEN
Add another client:receive() after sending the key and log the results.

This is the script so far:

Code:
host = '192.168.126.54'

port = 8001

name = 'SamsungTvRemote'

b64 = require('encdec').base64enc

ws = require('user.websocket')

json = require('json')

url = 'ws://' .. host .. ':' .. port .. '/api/v2/channels/samsung.remote.control?name=' .. b64(name)

client, err = ws.client('sync', 10)

res, err = client:connect(url)

if not res then

  log('connection failed', err)

  return

end

data, _, _, opcode, err = client:receive()

resp = json.pdecode(data)

log(resp)

if type(resp) ~= 'table' or resp.event ~= 'ms.channel.connect' then

  log('invalid response', data, err)

  client:close()

  return

end

key = 'KEY_HOME'

payload = json.encode({

  method = 'ms.remote.control',

  params = {

    Cmd = 'Click',

    DataOfCmd = key,

    Option = 'false',

    TypeOfRemote = 'SendRemoteKey'

  }

})

client:send(payload)

data, _, _, opcode, err = client:receive()

resp = json.pdecode(data)

log(resp)

client:close()

The result is this:

Samsung TV websocket 27.02.2023 15:54:54
* table:
["event"]
* string: ms.channel.unauthorized

-----------------------------------------------------

Samsung TV websocket 27.02.2023 15:54:54
* arg: 1
* string: invalid response
* arg: 2
* string: {"event":"ms.channel.unauthorized"}

* arg: 3
* nil

RE: Samsung / Tizen TV API v2 - admin - 27.02.2023

Comment out this check before the key is sent and try again.

Sorry but i don't understand what you mean with ' Comment out this check '

Add comments to this check:

I have a working script now using wss over port 8002. Only issue is that the TV keeps asking to accept the connection and it seems the token is changing all the time as i got a new one so now and then while testing.

Code:
host = '192.168.126.54'

port = 8002

name = 'MyRemote'

token = 16687249

b64 = require('encdec').base64enc

ws = require('user.websocket')

json = require('json')

url = 'wss://' .. host .. ':' .. port .. '/api/v2/channels/samsung.remote.control?name=' .. b64(name) .. '&token=' .. token

client, err = ws.client('sync', 10)

res, err = client:connect(url)

key = 'KEY_MUTE'

payload = json.encode({

  method = 'ms.remote.control',

  params = {

    Cmd = 'Click',

    DataOfCmd = key,

    Option = 'false',

    TypeOfRemote = 'SendRemoteKey'

  }

})

client:send(payload)

data, _, _, opcode, err = client:receive()

resp = json.pdecode(data)

log(resp)

client:close()

Hi there,

I am in the same situation as Joep.

websocket library working and comunicating with Samsung IP, but each time i send a KEY command the TV send us a new Token string and ask us to confirm the device.

Anyone have improved this?

And the wol packet i tried several scripts to switch ON the TV without success.... any idea about?

Here's a working WOL script. I just tested with my Samsung tv and it works. Also for my pc and i believe many other devices.

Code:
function wol(mac)

local m = ''

  for w in string.gmatch(mac, "[0-9A-Za-z][0-9A-Za-z]") do

    m = m .. string.char(tonumber(w, 16))

  end

  local udp = require("socket").udp()

  udp:settimeout(1)

  udp:setoption("broadcast", true)

  udp:sendto(string.char(0xff):rep(6) .. m:rep(16) , '255.255.255.255', 9)

end

wol('60:2D:BE:C3:4A:BC') -- MAC address of your device

Thank you very much Joep. I will try it later.
