When you installed all related dependencies in nodeRED could you see all new nodes included in the johnny package for example in the side menu of nodeRED??

You said that you don't have npm installed, in your raspberry. I recomend that you installed the last stable node version in your Raspberry SO and of course the last npm package manager first. Also use the last stable nodeRED in your project and not the default one that could be installed in the Raspberry SO.

Any way, check this link if it could help you:

Node "rpi-gpio out" doesn't do the expected in GPIO 18 (Pin 12)

Debug in nodeRED doesn't really exist.

You could trigger debug logs to the right side panel of nodeRED or use lamps in your nodes indicating the status like you know but not more.

If you need any more complicated debug in a more complicated logic in javascript or other backend language for your data received from your hardware devices I recomend implement this logic outside nodeRED using for example the IBM Loopback framework is you are using a nodeJS backend. I used it many years and is fantastic nodeJS backend framework. Thwen you could use the API services exported by this framework or others in your flows using the javascript node of nodeRED or directly the HTTP. I recomended the first option.

My 5 years experience in nodeRED tell me that not build your logic inside nodeRED only use nodeRED like a message router.

The correct flow must be: capture the outside dara inside nodeRED, transfom, persist, etc this data outside nodeRED (IBM Loopback for example) and publish the results alarms etc inside nodeRED to other UI services like Angular, React ot any client side framework that you prefered.

Good Luck in your project!

Thanks for the detailed answer.

With Debug window i meant the Panel / Window in NodeRED.
