Try these functions, they are untested so might not work at all. You have to parse any XML response manually

Code:

function request(host, url, urn, action, args)
  local body, http, ltn12, sink, res, err

  ltn12 = require('ltn12')
  http = require('socket.http')
  body = [[<?xml version="1.0" encoding="utf-8"?>
  <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
  <s:Body><u:]] .. action .. [[ xmlns:u="urn:]] .. urn .. [[">]] .. args .. [[</u:]] .. action .. [[></s:Body>
  </s:Envelope>]]

  sink = {}

  res, err = http.request({
    url = 'http://' .. host .. ':55000/' .. url,
    method = 'POST',
    headers = {
      ['soapaction'] = '"urn:' .. urn .. '#' .. action .. '"',
      ['Content-Length'] = #body,
    },
    sink = ltn12.sink.table(sink),
    source = ltn12.source.string(body),
  })

  if res then
    return table.concat(sink)
  else
    return nil, err
  end
end

function sendkey(host, code)
  local args = '<X_KeyEvent>' .. code .. '</X_KeyEvent>'
  return request(host, 'nrc/control_0', 'panasonic-com:service:p00NetworkControl:1', 'X_SendKey', args)
end

function getmute(host)
  return request(host, 'dmr/control_0', 'schemas-upnp-org:service:RenderingControl:1', 'GetMute', '<InstanceID>0</InstanceID><Channel>Master</Channel>')
end

IP = '192.168.1.2'
log(getmute(IP))
