Sony Bravia Authentication

[arnocl]

I cleaned up your code a little to be tailored more to my needs. Also included a status object checker, convenient to get a feedback of the actual settings of the TV. 

   

Common Functions:

Code:

function ipControlSonyTV(service, command) 
  local http = require("socket.http")
  local ltn12 = require("ltn12")
  require("json")

  local ip = "192.168.1.135"
 
  local response_body = { }
  local res, code, response_headers, status = http.request
  {
    url = "http://" .. ip .. "/sony/" .. service,
    method = "POST",
    headers =
    {
      ["HOST"] = ip,
      ["Accept"] = "*/*",
      ["Content-Type"] = "application/x-www-form-urlencoded",
      ["X-Auth-PSK"] = "************",
      ["Content-Length"] = command:len()
    },
    source = ltn12.source.string(command),       
    sink = ltn12.sink.table(response_body)
  }
 
  response = json.decode(response_body[1])
  return response["result"][1]
end

Resident Script (every 2 seconds or as much as needed):

Code:

command = [[ {"method": "getPowerStatus","id": 50,"params": [],"version": "1.0"} ]]
powerStatus = ipControlSonyTV("system", command)
powerStatus = powerStatus["status"]

if (powerStatus == "active") then
  grp.checkwrite('5/0/2', 1, 1)
elseif (powerStatus == "standby") then
  grp.checkwrite('5/0/2', 0, 1)
end

if (powerStatus == "active") then
  command = [[ {"method": "getVolumeInformation", "id": 33, "params": [], "version": "1.0"} ]]
  volumeInfo = ipControlSonyTV("audio", command)
  volumeStatus = volumeInfo[1]["volume"]
  muteStatus = volumeInfo[1]["mute"]
  grp.checkwrite('5/0/5', volumeStatus, 1)
  grp.checkwrite('5/0/7', muteStatus, 1)
 
  command = [[ {"method": "getPlayingContentInfo","id": 103,"params": [],"version": "1.0"} ]]
  sourceStatus = ipControlSonyTV("avContent", command)
  sourceStatus = sourceStatus["uri"]
  sourceStatus = tonumber(string.sub(sourceStatus, -1))
  grp.checkwrite('5/0/9', sourceStatus, 1)
end

Every control object has it's own event script
Power:

Code:

power = event.getvalue()

if (power) then
  command = [[ {"method": "setPowerStatus","id": 55,"params": [{"status": true}],"version": "1.0"} ]]
else
  command = [[ {"method": "setPowerStatus","id": 55,"params": [{"status": false}],"version": "1.0"} ]]
end

ipControlSonyTV("system", command)

Volume Step:

Code:

volumeDown = event.getvalue()  -- down = 1 | up = 0

if (volumeDown) then
  command = [[ {"method": "setAudioVolume","id": 98,"params": [{"volume": "-1","ui": "on","target": "speaker"}],"version": "1.2"} ]]
else
  command = [[ {"method": "setAudioVolume","id": 98,"params": [{"volume": "+1","ui": "on","target": "speaker"}],"version": "1.2"} ]]
end

ipControlSonyTV("audio", command)

Volume:

Code:

volume = event.getvalue()

command = [[ {"method": "setAudioVolume","id": 98,"params": [{"volume": "]] .. volume .. [[","ui": "on","target": "speaker"}],"version": "1.2"} ]]

ipControlSonyTV("audio", command)

Mute:

Code:

mute = event.getvalue()

if (mute) then
  command = [[ {"method": "setAudioMute","id": 601,"params": [{"status": true}],"version": "1.0"} ]]
else
  command = [[ {"method": "setAudioMute","id": 601,"params": [{"status": false}],"version": "1.0"} ]]
end

ipControlSonyTV("audio", command)

Source Select:

Code:

source = event.getvalue()
power = grp.getvalue('5/0/2')

if (not power) then
  grp.write('5/0/1', 1)
  os.sleep(1)
end

command = [[ {"method": "setPlayContent","id": 101,"params": [{"uri": "extInput:hdmi?port=]] .. source .. [["}],"version": "1.0"} ]]

ipControlSonyTV("avContent", command)
