TCP Socket Connection for Legrand

[a455115]

Hello Admin,

Would you help me to refactor the code so that it can use all the features of Open web net ? I tried to redo it myself for the temperature, but I'm sure it's not the right way since the string is different there.

Code:

if not sock then
  mappingtemp = {
    ['1'] = '1/1/1',
    ['2'] = '1/1/2',

  }
  mapping = {
   
    ['3'] = '1/1/3',
    ['4'] = '1/1/4',
    ['5'] = '1/1/5',
    ['6'] = '1/1/6',
    ['7'] = '1/1/7',
    ['8'] = '1/1/8',
    ['9'] = '1/1/9',
    ['10'] = '1/1/10',
    ['11'] = '1/1/11',
    ['12'] = '1/1/12',
    ['13'] = '1/1/13',
    ['14'] = '1/1/14',
    ['15'] = '1/1/15',
    ['16'] = '1/1/16',
    ['17'] = '1/1/17',
    ['22'] = '1/1/22',
    ['23'] = '1/1/23',
    ['51'] = '1/1/51',
    ['0215'] = '1/1/52',
  }
 
   function parselighting(what, where)
    log("Ok")
    local addr = mapping[ where ]
    what = tonumber(what) or -1

    if addr and 0 <= what and what <= 10 then
      grp.checkwrite(addr, what)
    end
  end
 
 
 
 
  function parsetemperature(where, value)
    local addr = mappingtemp[ where ]
    log(where)
    value = tonumber(value) or -1

    if addr and 0 <= value and value <= 4050 then
      value = value * 0.1
      grp.checkwrite(addr, value)
      log("done",value)
    end
  end

 
 
 
 
 
  function parse(msg)
    log (msg)
    length = string.len(msg)
   
    if length == 11 then
    log("length",length)
    local who, where, dimension, value = unpack(msg:split('*'))
    if who == "#4" then
    who = string.sub(who,2,2)
    who = tonumber(who)
    parsetemperature(where, value)
end
    end
     if length == 6 then
      log("length",length)
       local who, what, where = unpack(msg:split('*'))
            who = tonumber(who)
       -- lighting
        if who == 1 then
      parselighting(what, where)
      log(what)
      log(where)
    end
  end
   
  end

  function read(sock)
    local buf = {}

    while true do
      local ch, err = sock:receive(1)

      if ch then
        local pr = buf[ #buf ]

        buf[ #buf + 1 ] = ch

        if ch == '#' and pr == '#' then
          break
        end

      else
        return nil, err
      end
    end

    if #buf > 0 and buf[ 1 ] == '*' then
      return table.concat(buf, '', 2, #buf - 2)
    end
  end

  sock = require('socket').tcp()
  sock:settimeout(1)

  res, err = sock:connect('192.168.1.195', 20000)

  if res then
    sock:send('*99*1##')
  else
    log('connect failed', err)

    sock:close()
    sock = nil
    os.sleep(1)
  end
end

-- socket handler
if sock then   
  res, err = read(sock)

  if res then
    log(res)
    parse(res)
  elseif err == 'closed' then
    sock:close()
    sock = nil
  end
end
