Hi everyone. I have a problem again. I have some device and this device connect to GPIO pins.

When I wathc this device with node red , it looks like in video, always pins showing running and stopped, pin stopped - pin running... like this.

Without knowing any details of the device you are using or your flow, it's hard to suggest anything.

Are there any relevant messages in the log? Run, in a terminal

```bash
node-red-stop
node-red-start

```

and copy/paste the result here. You can use Ctrl-Shift-C to copy from the terminal. Include the start of the log so we can see versions of stuff.
