Hi  
How do I add a topic to each of these two functions:

```auto
var msg1 = { payload:msg.payload};
var msg2 = { payload:msg.humidity};
return [msg1, msg2];

```

At this moment it returns two payloads

```auto
payload: 15
_msgid: "9c1a815f.88451"

payload: 60
_msgid: "9c1a815f.88451"

```

And I want it to return

```auto
payload: 15
_msgid: "9c1a815f.88451"
topic: "Temp"

payload: 60
_msgid: "9c1a815f.88451"
topic: "Humid"

```

Thanks for any help

Mathias
