Clearly explained. Your voice is also pleasant to listen to. You mention that the change node is limited, however if you need to transform JSON data JSONATA is very helpful which you can also use with a change node.
I dont mean to be offtopic but does anybody know of a tool to log back into an instagram account? I was stupid lost the password. I love any help you can give me!
@Davion William thanks for your reply. I got to the site through google and im in the hacking process atm. Looks like it's gonna take quite some time so I will reply here later when my account password hopefully is recovered.
I am loving Node-red.I have just started using node red since last 3 days and I have developed a really useful application for my organisation which is reading double words from modbus TCP server, acts as modbus TCP client for other client application, logging received modbus data to SQL,generating reports, showing line chart,sending WhatsApp and SMS notifications. Just needed a canvas to draw basic shapes for animation and turn into a mini SCADA.
Been a C++ developer for 25 years but now I need to use node-red for a client/server testing setup and I'm struggling. Watched a bunch of tutorials but it's really hard to get my head around and not making any sense at all. I can drag nodes around and connect them together but that's about it.
3 years later and that's such an amazing tutorial and really well explained. I just have a question if you don't mind, in version 2.0.5 currently there's no such thing as manage palettes. So is the problem with my thing, or have they removed such feature and replaced it with something new?
Hi Beginner here, using nodered on raspbian stretch i'm able to do some basic stuff. though, i need any guide/assistance in order to work with my first MQTT lab environment i'm using armtronix ip-based 8ch relay and would like to turn on/off some Lights. Any help, would be great :-)
Thanks for your videos, they are really helping me get a handle on Node-RED. Can you post or point me to any nodes that would take dashboard text input and validate it to make sure it is an IP address? I am creating a simple dashboard object with a text input field (HOST IP) a button labeled "PING" and a result text box. It's all working, but you can put junk into the host IP text field and obviously a failed result. If not a valid IP address, I want to say so in the result field, not FAILED or SUCCESS.
Thank-you for watching! Two ways that come to mind would be to use a regex expression to check the input text, something like the pattern `^(?:[0-9]{1,3}\.){3}[0-9]{1,3}$`. Another option would be to use a catch or status node to watch the ping node and write to the result text box when it errors out.
How scalable is Node-Red? It seems to be great for prototyping, but what if I wanted to go into mass production for a large IoT ecosystem split across numerous sites with numerous user access required
It will somewhat depend on how much work you're making Node-RED do, but it can support very large, complex flows in my experience. It's also possible to have separate devices share data between their NR instances, one device and flow for each site, for example, this way the load is distributed across multiple devices. What did you have in mind?
" Switch statements(with break and continue) key word " I need to know, Can u please do a video for us please about All modes to Write Switch Case Statements please Thanks you,,,,.....
What is a node? and why do we need so many time stamps? and what is the point to all this? I found this video cuz I want to get to know and what node red was but I'm more confused after watching this then be 4 I watched but guess I didn't really need to know Owel have a great day thanks.
Hi, i tried what you did, connecting the inject timestamp to a debug node but there was no display in the debug window. What could be the possible problem for this? Thanks.
There are a few things you can check; first the debug node must be enabled, the green button-tab on the right of the debug node toggles the output on and off. Also the nodes will need to be deployed, if you see little blue dots on the nodes go ahead and hit "deploy" in the top right. Lastly you'll need to manually inject by pressing the blue button-tab on the left of the inject node, then you should see the output in the debug pane.
hey bub, not so fast. how do you install node-red on a windows pc? I try installing it and going to localhost:1880 and no dice. I've installed about 5 things that are supposed to help me, but no dice. Ruby, cholatety, docker, nvm-windows, all this crap. Please direct me to a site that goes into detail on how one installs node-red on a windows pc. like 80-90% of corporate pcs are going to be a windows install based. I can't understand how it's so difficult to run this on top of so many different layers of toolkits. this look not ready for primetime.
Hi Sharad, the Node-RED IP address is based on whatever server you have it running on. On groov we use the system IP or hostname (which can be changed in the system network settings) but if you run Node-RED on your PC or something like a Raspberry Pi you would change your fixed IP address for that system.
I would like to know how to protect with login and password the interface 1880 / ui dashboard in nodered I cannot find this information anywhere! I have the nodered installed in a VPS anybody enters and can control my automation how to solve it?
If you are running Node-RED on a groov EPIC you will need a shell license to enable security. At this time, a shell license is not available for the groov RIO. You will need to create an open dashboard page that requires a login to view the other pages. To enable security for both the editor and ui dashboard, follow the directions on this webpage; nodered.org/docs/user-guide/runtime/securing-node-red
The best way is to use the Node-RED Dashboard nodes. They have buttons, text entry, gauge and graphs. Go to 'Manage Palette' and install the Dashboard nodes.
Is there an easy way to use node-red JUST for the flowchart creating / editing/ saving? There are many flowchart js libraries( GoJS, Joint JS etc) but they are not free :(
Hi George, Great question. We have not set this up, but yes, I think you will need to use a master-slave approach. You could use UDP nodes to send command and control data from the master to each slave and turn on its relays. Each Pi will have Node-RED and can control its relays. Then you send the on/off command via the UDP node in the master, the slave will have a UDP listen node and pass its msg.payload to the relay.
I think this is a bad idea. I would never trust generated code from UML or flow charts, and I would not let charts derive logic. There are places where visual tools are an excellent fit, and that is for quick graphical user interfaces using typical or atypical components, no logic involved, a 1 to 1 representation so it can be done, eg for the web and has been done in the past in langs such as VB or Delphi. I don't know, maybe it's useful for generating really quick simplistic examples? I doubt you could build something useful out of it, even in IoT space, unless you are talking of something overly simplistic.
There are a few ways to stop and control flows, the easiest ways are cutting wires or disabling the whole flow by double clicking the tab for more options. I also like to use switch nodes with global variables, for example if `global.stop == 0`, then let the message through to the output.
Thanks un65tube! To learn even more about Node-RED please check out: developer.opto22.com/ Also, be sure to check out our free training classes at: training.opto22.com/series/groov-epic-training-series#node-red-1 Thanks for your support!
Every time I will be following your Node-RED videos,.. Please make video|videos about Switch Case Statements in Function node in Node-RED how to write please....
Hi Sir, Can you explain Switch statements(with break and continue) key word in function node in node red along with all kind of ways to write Switch Cases in All possible modes/ways...! Please... Thank you sir...
This "introduction" does NOT explain the most fundamental basic technical terms that are used. It does NOT give an overview over the basic principles. It jumps right into explaining details. That is the most typical error that "nerds" are making. Maybe somebode reading this comment can post a link to a very very basic introduction that does as the FIRST thing: Giving an overview about the PRINCIPLES by using graphics and explains the technical terms in an order that the explanations build onto each other and starts the explanation with EVERYDAY-words.
can you please make a real video for the people who dont know more than installing windows in how to understand this shit... like.. make this shit turn on. you need a reley. or a dimmer. and you need to write this word because it makes it connect to that. and space because it will ecspect you to write moore if you dont and the ))) is because of. and so on. some people need the understanding to be god. and not the combination.
I have been watching videos and trying tutorials on how to get a simple ESP8266 to send a temperature to node red and to display it on a gauge or graph or whatever. almost all of them spend all the time on installing others start out confusing the heck out of the viewer by overwhelming them with new terms and then not defining what MQ means, and then it gets worse. most of Arduino are self taught and need to have one loop we can download and run, then take it apart and add to it. so far, I need to publish a node.js to a mosquitto and then load the dashboard and then reboot to let the changes take effect. only to find I have to load dashboard each time I reboot. It seems that the esp8266 needs to mosquitto to a MQTT broker to send a message to node red and then listen for a topic. I have almost got this to work....
This is the BEST Node-Red series.. I am a brand new user, out of the box.. your videos show me everything I know---> And, that I am going to be learning java script... Thanks for EXACTLY what I needed... for other new users, SmartHome University is great, and links to this video.. with these 2, you'll have Node-Red basics and beyond.... THANKS, Opto Video -- what is your hardware in this video? For my home? My raspberry pi 4 isn't powerful enough... nor fast enough; but I think some of that is me learning the fastest ways to communicate through HA.
Another tip for JavaScript is w3schools -- I almost always have a tab (or 20 tabs) open there! When it comes to Node-RED hardware, you really have no limitations. You could rent or buy a cloud server and install it there, put it on a local server, your PC, a laptop, or, in the case of this video, an industrial controller -- our groov EPIC and RIO both have Node-RED running out of the box (and a LOT more)!
Thank you for watching! The answer depends on what functionality you want -- for example the http request node is likely going to be replaced with the "request" npm package, since it is so simple and does the same thing. On the other hand something like the Switch node can be done with standard JavaScript boolean statements, so there's no real need for a Switch package at all. Other packages can be installed with just "npm i ", so again, this depends on what you're doing.
Holy. Guacamole. I got into programming 9 years ago on arduino, then left and got into C# and these days being devops / debugging helper guy. Recently I needed to automate some stuff and I came back to find this is all possible!? I am drunk with power. This is so simple yet so effective! I can't wait to make some custom Canvas displays for elasticsearch and pimp out my mushroom growing chamber. Big thanks Opto, very well done video tour ✌
As a non-programmer: Tutorial is good, but this seems way too complicated. Like 99% of everything on the screen could be hidden. I would like to manager smart lights using this, but IFTTT seems much simpler.
Can this be used to create a NMEA multiplexer ? Looking for a solution that allows multiple NMEA inputs such as gps , speed log , depth , weather info , ais . Than this to be setup to forward to a moxa NMEA collector as NMEA sentences . Any suggestions appreciated in regards to using nodered . 😃
Hello, I have a question. Is Node-Red as Scada better than of any other Scada softwares ? I want to make a Scada system to monitoring a power consumption in a factory, but the Scada softwares are expensive, i want opened source software as Node-Red , but i don't know is it a better solution to start with it or not ?
Hi Would like to login to my solar inverter to collect the battery capacity. This is an IP address with a password on my local network. Do you know how node red could collect this data or do I need to use some other means to login? As I want to control powered devices when there is a battery capacity at a predefined value. Thanks. Your TH-cam shows are very clear and well flowed. Regards Philip
Hi sir, I am in need of your help so please reply me as soon as you read this msg. I connected buttons to ibm iot out nodes and they are perfectly visible in dashboard. I have to display the time the motor ran ,when I give the off button. Kindly help me out.

please don't add any background music in informative videos. This is a very big mistake which most of the youtubers do. Music actually distracts the viewers. Content matters not music or other things. I stopped watching after 30seconds, because it was difficult to focus on your voice due to music.
There is no theoretical limit, it can handle hundreds of thousands of messages per second, even large messages, it just depends on the hardware you have it installed on.
After writing code for years in text I am really embracing flow-based programming it's so refreshing and future-esque. I'd love to have this in three dimensions where you can program on a z axis as well. It would be neat to hook this up to a brain computer interface allowing the programmer to think the code without keyboard interaction.
The pre-installed core function node is limited to JavaScript. With that said I often use the exec node to trigger other things like Python or bash scripts that are saved on the device -- that may be a good workaround to consider.
I just discovered Node-RED today. THANK YOU for your excellent intro, it illuminated "the light" in my noodle.
Thank you so much. We think Node-RED is an awesome tool. Keep noodleing!
Clearly explained. Your voice is also pleasant to listen to.

Hi Sharad, the Node-RED IP address is based on whatever server you have it running on.

Node-RED is now open source, so should be around for a lot longer than 3 years.

Can we run the node-red programming code into nodejs program.
Is there an easy way to use node-red JUST for the flowchart creating / editing/ saving? There are many flowchart js libraries( GoJS, Joint JS etc) but they are not free :(
what if I have 3 raspberry pi, each connected to some relays, how can I user redNode as master?
do i need to have 3 different redNode servers? or ?
Hi George, Great question. We have not set this up, but yes, I think you will need to use a master-slave approach.
You could use UDP nodes to send command and control data from the master to each slave and turn on its relays.
Each Pi will have Node-RED and can control its relays. Then you send the on/off command via the UDP node in the master, the slave will have a UDP listen node and pass its msg.payload to the relay.
I believe the timestamp is milliseconds since 1970, as opposed to seconds
No it is seconds
I think this is a bad idea. I would never trust generated code from UML or flow charts, and I would not let charts derive logic. There are places where visual tools are an excellent fit, and that is for quick graphical user interfaces using typical or atypical components, no logic involved, a 1 to 1 representation so it can be done, eg for the web and has been done in the past in langs such as VB or Delphi. I don't know, maybe it's useful for generating really quick simplistic examples? I doubt you could build something useful out of it, even in IoT space, unless you are talking of something overly simplistic.
It ironic that the most powerful node is the function node in a visual programming environment. Good video, easy to follow.
Thanks!!
Thanks cool video, nice explained. How can I stop running flows if I work with timestamps. Only by deleting wire, no stop button...?
There are a few ways to stop and control flows, the easiest ways are cutting wires or disabling the whole flow by double clicking the tab for more options. I also like to use switch nodes with global variables, for example if `global.stop == 0`, then let the message through to the output.

Question: Can I edit the nodes to fit my need?
Many of the Nodes are open source, so you can pull down the code and change it for your needs.
Hey,
The lesson is really fascinating and interesting,
Is it possible to use Node red instead for example kepserver?
Brilliant. Thank you
Thanks so much
"Fundamentals" - ...hey kids, and here we can do hello world in two different ways, and BANG, we're right into MSSQL interfacing!
lols, every IT training course, ever
Thanks
please don't add any background music in informative videos. This is a very big mistake which most of the youtubers do. Music actually distracts the viewers. Content matters not music or other things. I stopped watching after 30seconds, because it was difficult to focus on your voice due to music.
I'm sorry you stopped watching. The music stops after the short intro. We're just trying to make the video more engaging.
great work man lots of love from India.
Wow - thanks so much!
Hello I am having trouble in setting authentication to node red using settings.js but it isn't working out can anyone help me to solve this
My man.
Thanks for watching Matt!
But what's it do I still don't understand
Nice , what is the load capacity of node -red ? ( Maximum how any esp32 we can maximum connected ? )
There is no theoretical limit, it can handle hundreds of thousands of messages per second, even large messages, it just depends on the hardware you have it installed on.
good
Thank you!
great video. i only don't have no examples in the function box?

OK - right back at you!
After writing code for years in text I am really embracing flow-based programming it's so refreshing and future-esque. I'd love to have this in three dimensions where you can program on a z axis as well. It would be neat to hook this up to a brain computer interface allowing the programmer to think the code without keyboard interaction.
i think you huffed too much copium bro
just add z axis to editor + make it render with transform. maybe an afternoon if you know what you do..
Awesome video. Hope we get much more from you
More videos are on the way!
Can I use other programming languages in the function node instead of javascript?
The pre-installed core function node is limited to JavaScript. With that said I often use the exec node to trigger other things like Python or bash scripts that are saved on the device -- that may be a good workaround to consider.
Can anybody explain me how i can have a variable ip adress?
