Z-Wave JS UI standalone server on a Raspberry Pi with RaZberry 2

Instead of buying  a new Z-Way adapter I thought it would be a nice project to reuse the almost 10 year old adapter together with a Raspberry Pi 2. 

After some Googling I found Z-Wave JS UI(ZUI) which is both the server part and an UI.

The described installation could be used for almost "any" Z-way interface and for "any" Linux distribution.

Introduction
The ZUI installation is going to be used together with Home assistant. After some tinkering with the above mentioned hardware it worked.

Prerequisites 

You need a Linux machine with some Linux OS + the Z-way interface

Detect the hardware

After connecting the RaZberry card(RZC), or a USB dongle, it will probably appear as something like "/dev/ttyXX". Check with "dmesg | grep tty"

RaZberry card

Per default the RX/TX pins, on any Raspberry Pi, are setup as a serial console. This means that you can use a USB console cable to log on from almost any computer, which have an USB port, to the RPi. Since the RZC is using the same pins we have to disable the console function with 

sudo rasp-config

3. Interface options => 

    I6 Serial Port Enable/disable shell messages on serial connection

    

    Would you like a login shell to be accessible over serial? => No

    Would you like the serial port hardware to be enabled? => Yes

    The serial login shell is disabled

    The serial interface is enabled  => OK

Do a restart "sudo reboot now" and check "dmesg | grep tty".

Install Z-Wave JS UI

Docker seems to be the prefered method but here I'm using the NPM method.

Via ssh/terminal start with an update

sudo apt update && sudo apt full-upgrade -y && sudo apt clean
and then install Node.js(V22 LTS) and NPM 

curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -

sudo apt install -y nodejs 

sudo npm install -g npm@latest

and check the install with "node -v && npm -v".

Then the actual application "sudo npm install -g zwave-js-ui",  start with "STORE_DIR=~/.zwave-js-ui sudo zwave-js-ui" and check at "http://your_host.local:8091".

To be continued !
