If it’s that it’s good 
You launch the container with the option « -d » which means « detached », so the container launches in the background and not in the foreground.
If you want to see how the container is doing, you can do
docker ps
Or
docker logs 8d329
to see the container logs (the ID displayed on your screen is the container ID)
Thanks Pierre-Gilles for your response.
Here’s what it returns, it doesn’t seem to be okay

You are running the container on a port that is already in use
Run:
docker ps
To check that you are not running node-red twice
No, I only have one Node-RED container apparently

And on your machine, you didn’t launch anything else? You didn’t try anything before launching this container?

The port already in use 9898, this is the port I declared in Node-RED to connect the Xiaomi gateway. Yes, I tinkered a bit 
I installed another Docker container Node-RED, which worked, but I realized that both were installed, so I uninstalled the second one to keep the one installed with your method. That’s why I wanted to start over with Node-RED.
Currently, the container is installed, I see it with docker ps, but it seems to restart continuously, and I no longer have access to the web page.
I’ll check your link
Thanks
The error message is clear: something is running on the port, so somehow you must have left a program running on the same port!
Initially, I unplugged the gateway, but that didn’t change anything (since the affected port is the gateway’s one). I must admit I’m not very knowledgeable in this area. Then, I took a more brute-force approach: using FileZilla, I tried to delete the /var/lib/node-red file, which resulted in many responses.
Command:
rm "/var/lib/node-red/node_modules/@serialport/stream/CHANGELOG.md"
````Error:``
rm /var/lib/node-red/node_modules/@serialport/stream/CHANGELOG.md: permission denied
I then ran:
docker restart node_red
Now, I can connect to the Node-RED web page. Everything is working correctly. I think this changed something on port 9898, but what? 
Thanks for your help; you’ve taught me a few things again.
Hello everyone.
I’m just starting to explore Node-red and I already have a problem…!
I followed the video tutorial carefully, but when I try to inject a value so that it is retrieved on the Gladys dashboard (to do a test as in the video), nothing is injected at all :-/
I am connected yet, when I press deploy, I have a message Successfully deployed but I do not have Successfully injected: 12 and the dashboard remains on No value recorded
How do you think I can debug the issue?
Oops… it worked. I didn’t realize I had to press the blue button on the left of the inject!
I’m back here but tell me if I should post in the topic I created about the Solaredge integration…
So I managed to get Node-red to communicate with Gladys.
But now I’m stuck: the information returned by the Solaredge API is in JSON format. I get all these values:
The one I’m interested in right now is currentPower.
But I don’t know how to extract it from this JSON and send it to Gladys. Do I need to « parse » something? I’m not even sure that’s the right word ^^
Hello Guim 31
To quickly progress in node red, check out this video series, it explains quite a few things that helped me with the Xiaomi Gateway tutorial: [Course 2.2 Bioautomatics] Node-RED Interface - YouTube.
Then in the tutorial: [NODE-RED]Piloter la Gateway Xiaomi chinoise - #4 par Psoy
At the bottom of the tutorial, in the « Sensor Part » section, I discuss the extraction of data from a Json. You’ll find it in the « function node ». You’ll need to adapt your data.
That should do it. 
Your turn to play.
Awesome these Bioautomatique videos!!! I succeeded thanks a lot
Rather than:
docker run -d \
option 1
option n
node:red/node-red
On Raspberry Pi, wouldn’t the script launch proposed on the official Node-Red installation page be more suitable?
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
If there are no operational interferences!
No, I recommend running Node-RED via Docker. However, the script you listed here seems to install Node-RED directly on the host, which is less practical for several reasons:
At least with Docker, you have a container and everything is isolated inside it. I really recommend using Docker
I’m running it on a NUC (Beelink BT3 PRO) after following the tutorials for an Ubuntu Lite installation (Debian Mini next)
Thanks for the clarification, no more questions to ask to make node-red work with Gladys! 
Hello @VonOx,
I’m trying Node-RED with Z-Wave.
I can use a motion sensor, but I don’t know how to use my Qubino ZMNHJD1 modules for my heating.
I would like the following functionality:
a switch, or linear dimmer, in Gladys
Either with configured names (off, frost protection, eco, comfort), or with value ranges that would correspond to the modes (0-10; 11-20; 21-30; 51-99)
I can’t provide the correct value format to control the module.
Here is my flow:

I get the error: Error: Syntax error: « setValue »
If anyone has any ideas, I’m taking them.
Thanks in advance
EDIT 02/10/2022
I managed to turn on my heating with 4 different modes 
Now I just need to figure out how to do daily programming 
EDIT 02/16/2022
Daily programming done
Now I would like to do
Thanks @cce66
You can delete your 2 messages, I modified mine
Hello, I tried to integrate Node-RED. I’m almost done, I’m stuck when I edit the settings.js file. I use the following command « nano /var/lib/node-red/settings.js »
