I have fixed your post so that the flow is importable. For future reference, 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 
```

````

See this post for more details - [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506)

Well I can't see any problems with that, and importing to my system does not cause an issue. The 'pin' number is badly named, it refers to the GPIO number, not the pin.

Can you open a command window and run  
`ps -aux |grep nrgpio`  
and paste the result here. Use the same technique as for posting flows, that will stop the forum messing with the layout. I want to check if the python script that interrogates the non-working pin is running, and if it is if there is anything unusual about it.
