==Node-RED installation and setup==
 +
 +
We are going to set up Node-RED in Linux virtual machine. For Node-RED to work, you would need to install Node.js version 14.00 or higher, if you already have Node.js installed, verify Node.js version using this command:
 +
<pre>
 +
node -v
 +
</pre>
 +
If you do not have Node.js installed, run these commands to install it:
 +
<pre>
 +
sudo apt install curl
 +
curl -fsSL https://deb.nodesource.com/setup_14.x | sudo -E bash –
 +
sudo apt-get install -y nodejs
 +
</pre>
 +
Once we have Node.js installed, we can install Node-RED. Use this command to install:
 +
<pre>
 +
sudo npm install -g –unsafe-perm node-red
 +
</pre>
 +
Use the command ''node-red'' to start a local server. Here is how the terminal should look like if the server starts correctly:

 +
Once you have the local server running, use the local IP and port number in your internet browser. In this case, we are using 127.0.0.1:1880:

 +
 +
For MQTT usage, we are going to need MQTT-specific nodes. Use the side menu to navigate to Manage Palette section and install these nodes:
 +
*node-red-contrib-aedes
 +
*node-red-contrib-mqtt-broker
 +
