HowTo: Node Red – Install New Nodes

The great thing about NodeRed, in addition to the simple programming, is that there are all sorts of plugins (in the NodeRed-Universe called “nodes”) with which the functionality of NodeRed can be extended.

A list of currently – officially available nodes can be found at:

If you found a node that you want to install, you can do so via the “Palette Manager” found in every NodeRed installation.

How this works is described in the following article.

Hints for our lovely english readers: Basically, many of the articles on are translations from the original german articles. Therefore, it may happen here and there that some illustrations are not available in english and that some translations are weird/strange/full of mistakes or generally totaly wrong. So if you find some obvious (or also not obvious) mistakes don't hesitate to leave us a hint about that in the comment section. 
Also please don't get confused, that instead of a "dot" often a "comma" is used as decimal separator. 🙂

Safety instructions

I know the following hints are always a bit annoying and seem unnecessary. But unfortunately, many people who knew it "better" from carelessness lost their eyes, fingers or other things or hurt themselves. In comparison, a loss of data is almost not worth mentioning, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Even the coolest project is worth no injury or other annoyance.

Of course NodeRed should already be installed so that you cango through this article.
How to prepare this and a RaspberryPi and then install NodeRed on it is described in the following articles.

Required material:

In the following list you will find all the parts you need to implement this article.

Log in to the NodeRed configuration interface

Before you can edit your NodeRed configuration you must - if activated - first log in to the NodeRed configuration interface.

View of the login screen. Here you have to enter the login details that you entered during the configuration of the login. Information about this can be found in the article NodeRed - User Login Setup.

Install new nodes via the configuration interface

Open the configuration interface of your NodeRed installation.

Now click on the three gray horizontal bars on top-right and then on “Manage Palette”.
In the window that opens, select the “Install” tab.
In the text field underneath you can now enter search terms to find your desired node. In this example, an “Alexa” node is installed, which makes it possible to control NodeRed from an Alexa device.
After you have found your desired node in the suggestion list, click on the corresponding “Install” button.
Before the installation starts you have to confirm this once again in a small window. Here you also have the option of clicking on “Open node information” to see more information about the desired node.
The installation starts as sonn as you have confirmed the installation by clicking on “Install”. This is indicated by an animation in the search suggestion list.
If the installation was successful you will be shown which concrete nodes have been added to your palette.
In addition, the “Install” button of your search suggestion list is grayed out. This indicates that you have already installed this node.

Have fun with the project

I hope everything worked as described. If not or you have any other questions or suggestions, please let me know in the comments. Also, ideas for new projects are always welcome. 🙂

P.S. Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do this because I enjoy it, but if you appreciate it that I share these information with you, I would be happy about a small donation to the coffee box. 🙂
