Hi,  
I have one pc with ubuntu to test my code  
and one Raspberry (so raspberry) for my home automation.

Why this simple function

```auto
const pay = Number(msg.payload.toFixed(1));

```

in Ubuntu is ok and in Raspeberry show this error ?

```auto
TypeError: msg.payload.toFixed is not a function

```

Because the payload is NOT a number on your PI flows.  
Simple to verify with a debug node BEFORE the function.

It's a temperature value, I thought it was a numeric value, not string ....  
Thank you very much (and thanks for your patience) ....
