Getting Started with Node-RED Dashboard

This post is an introduction to Node-RED dashboard with Raspberry Pi. We’ll cover how to install Node-RED Dashboard and exemplify how to build a graphical user interface.


What is Node-RED Dashboard?

Node-RED Dashboard is a module that provides a set of nodes in Node-RED to quickly create a live data dashboard.

To learn more about Node-RED Dashboard you can check the following links:

Installing Node-RED Dashboard

To install the Node-RED Dashboard run the following commands:

pi@raspberry:~ $ node-red-stop
pi@raspberry:~ $ cd ~/.node-red
pi@raspberry:~/.node-red $ npm install node-red-dashboard

Then, reboot your Pi to ensure that all changes take effect on Node-RED software:

pi@raspberry:~ $ sudo reboot

To open the Node-RED UI, type your Raspberry Pi IP address in a web browser followed by :1880/ui as shown below:


At the moment your dashboard is empty – as you can see in the following figure – because we haven’t added anything to the dashboard yet:

Creating a UI (User Interface)

In this section we’re going to show you how to create your UI (User Interface) in Node-RED.

The Dashboard Layout

Open another tab in your browser to access Node-RED with:


Scroll down on the nodes section.  You’ll see you have a set of nodes called dashboard as shown in the following figure:

Nodes from the dashboard section provide widgets that show up in your application user interface (UI).

The user interface is organized in tabs and groups. Tabs are different pages on your user interface, like several tabs in a browser. Inside each tab you have groups that divide the tabs in different sections so that you can organize your widgets.

Every widget should have an associated group that determines where the widget should appear on the user interface.

To create a tab and a group follow the following instructions (see figure below):

  • On top right corner of the Node-RED window you have a tab called dashboard.
  • Select that tab (1). To add a tab to the user interface click on the +tab button (2).
  • Once created, you can edit the tab by clicking on the edit button (3).

You can edit the tab’s name and change its icon:

After creating a tab, you can create several groups under that tab. You need to create at least one group to add your widgets. To add a group to the created tab, you need to click on the +group button (4).

Then, you can edit the created group by clicking on the edit button (5).

You can edit its name, select its corresponding tab and change its width.

Dashboard Theme

The Node-RED Dashboard has a white background and a light blue bar by default. You can edit its colors in the Theme tab on the up right corner as show in the following figure.

Change the style, deploy the changes and see the Dashboard UI changing its colors. For example, like in the following figure:

Dashboard Site

At the right upper corner of the Node-RED window, you have another tab called Site that allows you to do further customization as show in the figure below.

Feel free to change the settings, then deploy the changes and see how the UI looks. At the moment you won’t see much difference because you haven’t added anything to the dashboard yet. Those changes will be noticeable when you start adding widgets to the UI.

Creating a User Interface – Example

In this section we’re going to make a dashboard example to show you how you can build and edit your own dashboard – we won’t actually add functionalities to the widgets – we’ll do that in future projects. This dashboard will have the following features:

  • Two different tabs: one called Room and another called Garden
  • The Room tab will have two groups and the Garden tab will have one group
  • We’ll add a color picker and a switch to the room groups
  • We’ll add a chart to the Garden group

Creating the Tabs

On the top right corner on the Node-RED window, select the dashboard tab and create two new tabs by clicking on the +tab button.

Edit one tab with the following properties:

  • Name: Room
  • Icon: tv

And the other one with the following:

  • Name: Garden
  • Icon: local_florist

Then, add two groups to the Room tab and one group to the Garden tab. The following figure shows how your dashboard layout looks.

Adding the Widgets

Add a switch, a slider, a colour picker and a gauge to the flow as show in the following fig.

Double click on the switch. A new window pops up.

In this new window you can choose where you want your button widget to appear. In this case we want it to appear in the Room tab, Group 1 as highlighted in red in the previous figure.

Then, do the same for the other widgets but add them to the following groups:

  • slider: Group 1 [Room]
  • colour picker: Group 2 [Room]
  • gauge: Group 1 [Garden]

Deploy the changes and go to the dashboard UI to see how it looks.


Your dashboard has two tabs: the Room and the Garden as highlighted in the following figure:

Here’s how the room tab looks with two groups.

And here’s how the Garden tab looks with one group.

Wrapping up

In this post we’ve shown you how to build a user interface with Node-RED.

We hope you’ve found this post useful.

Thanks for reading!
