TCP Socket Connection for Legrand

[admin]

This is not a proper protocol implementation, but see if this works for you:

Code:

function openwebnetcmd(ip, cmd)
  local socket = require('socket')
  local eot = string.char(4)
  local sock = socket.tcp()

  sock:settimeout(1)

  local res, err = sock:connect(ip, 20000)
  if not res then
    alert('connect failed ' .. tostring(err))
    return
  end

  os.sleep(1)
  sock:send('*99*0##' .. eot)

  os.sleep(1)
  sock:send(cmd .. eot)

  os.sleep(1)
  sock:close()

  return true
end

openwebnetcmd('192.168.1.1', '*1*1*11##')
