Hi.  
I have an object with an array of objects. I want to use a function node to get one spesific value based on the object id.  
So if I only want temp from a speseific device/object  
`if msg.payload.object.id == "2920009404" then msg.payload = msg.object.temp`?

Have a look at the array `filter` function.

Thanks for the tip. Solved it with this code.

```auto
msg.payload = msg.payload.devices.filter(el => el.id === "V004b11e12")
msg.payload = msg.payload[0].data.controlSignal

return msg;

```
