Homebridge UI showing all details, also Node.js version.
When entering `node -v` in SSH Terminal I get 18.15.0.
`which node` shows "/usr/local/bin/node" 

Installed Homebridge image with Pi Imager. Where is the right path, where version 18.16.0 is installed?

How can I reinstall NPM because it seems to be missing?
Without NPM I can't install or update plugins for example.
