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: https://flows.nodered.org/
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 Nerdiy.de 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. 🙂
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. https://www.nerdiy.de/en/sicherheitshinweise/

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.
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.
Install new nodes via the configuration interface
Open the configuration interface of your NodeRed installation.
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. 🙂
