Hi! I get some data via API (battery status) into my Node-Red.  
The data has an array - up to 99 arrays and each of this array contains 4 values [0]...[3].  
I want to get the value from the latest array [80] out of 80 or [65] out of 65 and always value "3".

How can I do this?

Off the top of my head, a function node with...

```auto
msg.payload = msg.payload[msg.payload.length-1][3]
return msg

```

...should work (untested)

_assuming the array is in msg.payload_

Hi @Steve-Mcl !  
I guess, this was the solution.

Again what I did:  
Function node plus your mentioned lines:

```auto
> msg.payload = msg.payload.xx.yy[msg.payload.xx.yy.length-1][3];
return msg;

```

Remark:  
xx.yy --\> its a part of my payload/array where I get the data.

I'll check the changes during the next hours and let keep you informed!  
Thank you and all the best!  
Cheers

@Moach2000 - Whenever you post code in the forum, 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 
```

````
