Hi

I have this inject node, and works well.

How do I make a msg.topic and msg.payload function, so it will work as the inject node?

The equivalent Function node would be:

```auto
msg.payload = {
   "warning": { ... }
}
msg.topic = "zigbee2mqtt/R_Alarm_Køkken/set"
return msg

```

Hi knolleary  
And then after the question, then I found [Sending value from array to mqtt in nodered](https://stackoverflow.com/questions/66227926/sending-value-from-array-to-mqtt-in-nodered)

But can see that it's almost the same as you wrote.

Thx alot. 🙂
