Receive UDP string

[admin]

@AlexLV, see this example, it will accept "on", "off" and any numeric value:

Code:

data = server:receive()
if data then
  chunks = data:split(' ')
  
  if #chunks == 3 and chunks[ 1 ] == 'group' then
    addr = chunks[ 2 ]
    value = chunks[ 3 ]

    if value == 'on' then
      value = true
    elseif value == 'off' then
      value = false
    else
      value = tonumber(value)
    end

    if value ~= nil then
      grp.write(addr, value)
    end
  end
end
