Sony Bravia Authentication

[The Real Mr.T]

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)

Hi guys,
i try this Scripts and got error

Code:

Common functions:144: bad argument #1 to 'decode' (string expected, got nil) stack traceback: [C]: in function 'decode' Common functions:144: in function 'ipControlSonyTV'

Can you help me?
I dont know much about scripting.
Just a little less than basics.
