Sorry for being a n00b at this.  
I have found this [https://forum.pvoutput.org/t/nodered-home-assistant-uploader/2472](https://forum.pvoutput.org/t/nodered-home-assistant-uploader/2472)  
I have imported it in NodeRed and changed the entities etc.  
The problem is that my entities sends its values in KWh and not in Wh or watt.  
So I tried to create a entity template for that value in HA but I cannot use that entity in NR, so that doesn't work in this situation.  
Now I am searching for another solution but I am not a programmer.  
I think it would be possible to the same in NodeRed and change to value to = and do \*1000 or something.  
Maybe someone can help me?

Welcome to the forum!  
Can you show us what you have in your 'V' change nodes (one will do!)

Try using jsonata, like this;

![power](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/b/0/b0b1e89009ed40ecba29b82c929e54a2b7c18159.jpeg)

EDIT - If the payload is a **string** value, and not a **number** , then change the jsonata function to;

```auto
$number(payload)*1000

```

Getting this in debug info now.

msg : string[87]  
"Invalid JSONata expression: The left side of the "\*" operator must evaluate to a number"

Will try to ues $number(payload)\*1000 now

This is great, it works!  
Thank you! I would like to know how do you know this? Were can I study those codes and what is the "language" of the code?

It's jsonata, see [https://docs.jsonata.org/overview.html](https://docs.jsonata.org/overview.html)  
I'm no expert, I learnt all I know from @janvda here in the forum by learning from his examples.

Ok its the first time that I work with it.
