Installation manual Node-RED (use at your own risk)

WesleyFranken

Dear community,

I get a lot of questions how to install Node-RED in the Unipi Axon. Because I'm grateful for this product of Unipi I am happy to share some knowledge:

Put the latest Unipi Axon Open Source image on a 16GB using FAT32. Flash Axon.

sudo su
apt-get update
apt-get upgrade
reboot

sudo su
apt-get install evok
systemctl enable evok
reboot

sudo su
apt-get install build-essential
apt-get install curl software-properties-common
reboot

Install NodeJS and Node-RED. !!Answer Yes to all except for installing standard Raspberry Pi nodes!!

sudo su
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
systemctl enable nodered.service
reboot

Don't mind the errors of installing node-red-admin:

sudo su
apt-get install nano
npm install -g node-red-admin
reboot

Securing Node-RED: https://nodered.org/docs/user-guide/runtime/securing-node-red
Hash, copy and paste password:

sudo su
node-red-admin hash-pw
cd .node-red
nano /root/.node-red/settings.js
reboot

Copy the following:

allow-hotplug eth0
iface eth0 inet static
address 192.168.1.101
netmask 255.255.255.0
broadcast 192.168.1.255
network 192.168.1.0
gateway 192.168.1.1

and paste into file eth0:

sudo su
nano /etc/network/interfaces.d/eth0

reboot

Change password Unipi:

sudo su
passwd unipi
reboot

sudo dpkg-reconfigure tzdata

I hope this helps you to get more out of your Unipi Axon!

Beste regards,
Wesley

Hello @WesleyFranken,
we have dedicated Node-RED images for all our PLCs. They also contain example program with Dashboard UI: https://kb.unipi.technology/en:sw:03-3rd-party:nodered

@Martin-Kudláček From today that is ;-)

Thanks!

Well @WesleyFranken, for Axon and Neuron, we have the image for a few weeks;) It just wasn't presented to the public, only as a download on the said page. From yesterday, we have the image for all three platforms.

Hello I have istalled the Node red image on Unipi 1.1 but no desktop...only command line. How to RU or install the PI desktop please??

Martin Kudláček

Hello @FabioIT,
the Node-RED image is defacto a Raspberry Pi OS. You can proceed with any general tutorial for adding the desktop environment, which you can find on the offical Raspberry Pi OS webpage.
