How can I split a MQTT string

Hi.

First, could you please format your post correctly - it is important to surround your code with three backticks

```
like this
```

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

See this post for more details - How to share code or flow json


secondly, when copying a value from debug, please use the "copy value2 button that appears under your mouse when you hover over the message in the debug window


Lastly, can you post a screen snip of the debug output so we can see how it looks.
