Hi @Chenko

the docs cover how to send multiple messages: [https://nodered.org/docs/user-guide/writing-functions#multiple-messages](https://nodered.org/docs/user-guide/writing-functions#multiple-messages)

Do you mean you want to send multiple messages, or that you want to send one message but with more in it than payload and topic? If the latter then in a function node you can say  
`msg.someAttribute = something`  
You can also do that with a Change node.  
As well as the link suggested look at the page on Working with Messages.

Hi @Chenko

Here is a little function that sends multiple msg's. I don't know what your inputs are but I hope this helps you figure a method.

```auto
var IPS = msg.payload.ip.split("|");
var TOPIC = msg.payload.message.split("|");
for (var i in IPS) { 
msg.payload = {"ip": IPS[i]};
msg.topic = TOPIC[i];
node.send(msg);
}
return;

```

```auto
msg.payload = "1.1.1.1|2.2.2.2|.3.3.3.3"
msg.topic = "topic1|topic2|topic3"

```

This will send multipe messages (3)  
`{"msg", {"payload":{"ip": "1.1.1.1"}, "topic": "topic1"}}`
