Hi.
Your flow is unusable.
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.

What do you mean my toggle? Do you mean inverse? Or do you mean to flip between "on" and "off" or `true` and `false`? or do you mean when PIN 13 is HIGH to output a certain value?
Please explain exactly what you are hoping to get out of this
do you expect `{ payload: "reset" }` or `{ reset: true }` or `{ reset: "reset" }` ?

I think you simply want a switch node to filter out payload of `1` then a change node to set msg.whatever to "whatever" (no need for custom contrib nodes for something so simple)

I recommend watching this playlist: [Node-RED Essentials](https://www.youtube.com/playlist?list=PLyNBB9VCLmo1hyO-4fIZ08gqFcXBkHy-6). The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.
