Hi and welcome to the forum.

There’s a great page in the docs ([Working with messages : Node-RED](https://nodered.org/docs/user-guide/messages)) that will explain how to use the debug panel to find the right path/value for any data item.

Pay particular attention to the part about the buttons that appear under your mouse pointer when you over hover a debug message property in the sidebar.

![BX00Cy7yHi](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/b/d/bd1f333a9e043b061b39917c328b0094d3e52d30.gif)

Use the copy path on the item to get the correct name.

Also JSONata expressions do not use square brackets for object properties, so it would be  
`payload.data.device_status."temperature:0".id` Assuming the path was correct.

PS when sharing dat like objects it is best to copy the object using the copy value in the debug , and paste the object as text. Then we can be sure your path is correct and there is no ambiguity.

In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote `````)

````auto
``` 
   code goes here 
```

````

You can edit and correct your post by clicking the pencil ✏ icon.
