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
