Hi So just to clarify before i format everything.
Is it possible to install node-red on Ubuntu, install Zwavejs and an Aeotec dongle without using docker or HA.
Thank you in anticipation
Indeed.
I think there is some layering going on somewhere - but not one I have seen.
-
Install Ubuntu Server.
-
Then the Node RED installer
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered) --node18
This will give you a clean Node RED installed directly on Ubuntu with no Docker or HA
EDIT:
install some build tools prior to installing Node RED.
sudo apt install build-essential
Top job
Many thanks to all of you
Would it be better to use 18 or at least 16? 14 is almost out of support is it not?

Hi
I have got a little bit further as when I select port on the Zwave Controller ports are listedit is listed.
I ran
andrew@andrew-OptiPlex-3060:~$ sudo dmesg | grep tty
[sudo] password for andrew:
[ 0.095111] printk: console [tty0] enabled
[ 1.020759] 00:01: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A
[ 4.084963] cdc_acm 1-4:1.0: ttyACM0: USB ACM device
I did not change any other settings
I selected /dev/ttyACM0 and deployed.

I get this error

msg : error
"ZWaveError: Failed to open the serial port: Error: Permission denied, cannot open /dev/ttyACM0 (ZW0100)"
Thats fine - at least Node RED can now see it 
Do you remember the username you used during Node RED install
If you just used your own account do the following
sudo usermod -a -G dialout $USER and restart.
The user that is effectively running Node RED needs to be added to dialout
Hi again
Ran the command `sudo usermod -a -G dialout $andrew```
I am unsure what was supposed to happen but it asked for a password and then loaded all the usable switches
Re started ubuntu
same error
"ZWaveError: Failed to open the serial port: Error: Permission denied, cannot open /dev/ttyACM0 (ZW0100)"
sudo usermod -a -G dialout $USER
$USER is a variable - dont change it 
sudo usermod -a -G dialout $USER < - as is
(providing your running the command under your account)
You could do sudo usermod -a -G dialout andrew if you wish
and of course restart after

Thank you for your hep Colin
Many Thanks
You now have a bare metal Node RED instance.
Depending on your number of ZWave device's
the interviews might take a few minutes - if you have some that can sleep - you may need to wake them up - once or twice.
Your attention should now be here
and work down the guide
