Node Red (Pi installation) Nov 2018
Just installed pi os with noobs (Raspian v2.8 Nov2018), surprised that node red was preinstalled (nodered version 0.19.4).
What to do next after default installation:
1. Start node-red. Open browser, point to localhost:1880 Chk version (setup hamburger)
2. Pallette is not visible
chk npm version with npm -v
sudo apt update && sudo apt install npm ; however this seem not to work
then I tried "update-nodejs-and-nodered"
that did the trick.
3. Install the extra nodes:
sudo systemctl enable nodered.service
