Node Red MQTT on the Raspberry Pi
HTML-код
- Опубликовано: 5 фев 2025
- Node Red has quite rightly generated a huge head of steam in the 3 years since IBM released it as an Open Source project. Here I quickly review the interface and short circuit some of the installation and upgrade problems. If you need a reason to learn OO JavaScript then this too is an excellent starting point.
A BETTER UPGRADE IS HERE • Node-Red Raspberry Pi ...

Extremely well presented! Thank you. Subscribed!
I am truly honoured! I'd love to pop in and visit you when I drive to Prague next time.
No problem! Just announce yourself via Twitter or Facebook and I will tell you, if I can make it.
There is something so satisfying about watching a great video presented by a man doing an awesome Jeremy Clarkson impression.
Richard. Absolutely wonderful vid. One of the best, most comprehensive mixture of information i've seen anywhere. Thank you Thank you!!
Thank you Paul - must stop clicking the 'like' icon on my own videos..
Paul Morley Superbly spoken like an act in a Shakespearen play but with a real solid knowleable practiced flow.
Thank you for taking the time to produce such a thorough flawless presentation!
A BETTER UPGRADE IS HERE ruclips.net/video/z9a_ztJqaII/видео.html
You have a wonderful voice for narration. The content is fabulous too.
Thank you Carole. I appreciate your time responding.
I 100% agree
Probably the best node red video I've seen for beginners! Awesome job, man!
Ah - great to come home, grab a beer, site down and have my ego massaged. Cheers
This might just be the most informative, clear & 'goes-in-depth-but-not-in-an-overwhelming-kind-of-way' instructional video I've ever seen! And believe me I've seen thousands, on a wide range of (mostly IT related) topics. Exemplary!
Thanks. Hope it was of help.
I would like to express sincerely my acknowledgment for this video. I got graduated recently as Mechanical Engineer, (no deep knowledge about coding associated) and this video is helping me to manage useful info of the real world, and not dying in the way. It seems that the world is always telling us that is not possible to make our own devices and machines (instead of buying it) (and of course, not with social motivations), so thanks for take the opposite way.
Thanks and good luck in your forthcoming career.
Mr. Wenner, I keep a close watch on your articles and videos about new technologies. I appreciate your sharing and your effort.
This was long, but it was engaging enough and the topics interesting enough to keep me here for more than an hour, as I was following you step by step. THANK YOU for this magnificent work. I know this is hard to create. Really appreciate!
It was only when I completed it that I realised how long it was (in fact I removed all of the Python linked material). I appreciate your comments. Thanks.
Very well articulated. Not stammered. Very refreshing change from most other videos on any topic.
Few years already left after that publication, but probably it still is the best, and all-in-one video explaining Node-Red basics. Thank you for your effort.
Thank you!
A better route my be:- ruclips.net/video/z9a_ztJqaII/видео.html
Really great introduction to Node Red. Very clear and comprehensive video, thank you Richard for a well edited guide with great visuals to help re-inforce concepts. Can't wait to get started. Still waiting for upgrades to complete after 3 hours.
I've started to think that I should have posted an img file - still might some time. Let me know how you get on.
WOW, this was an impressive introduction to node-red and mqtt, including a complete description of the installation of node-red and mqtt. Thanks.
Thank you, your comment is appreciated. This is the product of some version mis-alignment issues that I had. Do have a Very Merry Christmas and a Happy New Year.
What a great help this has been for me. Eloquently put along with a great voice, I somehow felt very calm with you talking me through it. Ive subscribed and will be watching the whole series. Fantastic that you show so much about updating the Pi too, wonderful work, many thanks
Now look into my eyes and log in. Transfer all of your worldy goods into the following bank account trust me trust my voice ....... sleep sleep press those buttons ......transfer that money ..... Sorry Dean do let me know how you get on.
can i just say that this is the best , bar none , tutorial of node red on the interwebs and it is my 'go to' video when i have any sort of issue with the mighty Node Red
Thank you. Do go to the update - a lot has changed since this filming.
@@richard_wenner there is an update ? superb news
@@familyplans3788 should be referenced below the first video. ruclips.net/video/z9a_ztJqaII/видео.html
This is one of the best tutorials i came across for understanding node red integration with Rasp pi. BTW i am not a coder still node red makes it much more easy to integrate devices and communicate with each other as well as to the internet.
Yes, Node Red is brilliant! Do have a look at A BETTER UPGRADE IS HERE ruclips.net/video/z9a_ztJqaII/видео.html
I know this is an old video but wanted to thank you for one of the best videos on this subject. While I have a boatload of Raspberry Pi's around the house, mostly for KODI, and lighting display stuff, I had never tried Node Red simply because of, shall we say less than stellar information/videos on the web.
So, yesterday, using your video, I was successful in getting a Pi running Node Red and even sending e-mails which, for anyone who has tried to do send e-mails in a C or VB or other language, knows is not an easy feat. With Node Red, a few click, enter basic account information, deploy, DONE.
Brilliant best describes you ability to convey a subject in a clearly understood manner.
Hope to use this to get off of ewelink's [ITEAD Sonoff] server and use the Pi/Node Red/MQTT to run my home automation.
Thank you very much.
I appreciate this. Thank you.
Thanks Richard for all the effort you've obviously put into this great video. This is only the second time I've commented on a RUclips presentation and I'm doing it to show my appreciation and express my hope that you continue to share your impressive knowledge and teaching skills.
Much appreciated. Thank you.
extremely well done in presenting such complex concepts in easy to follow manner, thank you and pls do continue to post more
Wow!
I've seen dozens of videos on Node-Red, including the annoying guy who speak in exclamation marks!
None have been this easy to understand or as complete.
I didn't see your "Next video" you referred to at the end. I looked in your play lists and videos, but couldn't find them.
I can only imagine how much work it took to make this video. I wanted to thank you for spending that time. It helped me a lot. Please do more videos on this HOT subject.
IOT is exploding and ESP modules are everywhere.
You gained another devoted subscriber. Cheers.
Thank you - this is certainly the way to galvanise me into further action. I agree with you regarding the 'hot topic' issue (that and MQTT). There are however a couple of updates that make the process of installation and update on the Pi far easier (there should be a ref below). These videos do consume a lot of time. Many times I've things planned and the Master (Andreas Spiess - the 'Guy with the Swis Accent') has beaten me to it - with far better stuff.
@@richard_wenner I've seen all your videos now. You shouldn't compare your videos with that of that German Robot. His videos are so boring! great as a sleeping aid.
If you do a search, you will find that there is no good videos that deal with only node-red and MQTT, which is more than enough to run a small house with a smart phone as the UI.
It's always complicated with home assistant or OpenHAB or other flavors of the day.
The one video I found useful, was from BitLuni ruclips.net/video/GeN7g4bdHiM/видео.html which is well done.
The guy from "opto video" may have some stuff, but I just can't stand him long enough to find out with the way he talks in a constant state of exclamation mark. It's like a millennium whining in my ear, with an occasional shitty music.
You have a presentation style unique to you. Don't sell that short. Cheers.
@@pirateman1966 Ah that's a shame. We are going to have to agree to differ there. I drove out to see Andreas last year. Believe me he is a great bloke. In fact it must have been the year before last as he was my guest at the first TTN event in Amsterdam. Try Pete Scargill - he is another really good source and prolific blogger tech.scargill.net/
@@richard_wenner I have no doubt he's a nice and knowledgeable guy. A lot of people are nice and knowledgeable, but can't convey their knowledge. I think you misunderstood me.
I am sub'd to scargill's channel for a while now.
Honestly still a solid intro to NodeRed 5 years later. Thanks!
Cheers Eric
Great video @Richard, nice pace and really clearly spoken. Exactly what I was looking for. Top quality. : )
Thank you.
Thank you Kevin - this is appreciated.
Richard you are number 1, the information content has help me understand the basics I sincerely appreciate your incredible knowledge base.Big thank you from Melbourne
One of the best videos I've seen on any subject. Superb work and thank you. I look forward to the promised future ones.
Thank you - I've just have to find the time - have a good new year.
Richard, you just nailed it so hard! I wish I have seen this video far earlier. While most of the things mentioned in the video I am already aware of (learnt the very hard way), this could have saved me a lot of time. It is absolutely worth watching.
Thank you - it's best to achieve things for yourself and then have them confirmed (it helps with the longer term retention - and feeling of self worth :) )
A new favorite channel for me. I can detect when something is well done and I sure that's the case here. Looking forward to learning a lot.
Your comments are appreciated - thank you.
Good tutorial. Had a poke with Node-red just today found it confusing initially but its quickly making more sense.
Going to revisit this video a few times when I have more time to play with the hardware side.
Best tutorial on Pi, node-red and MQTT setup I have ever seen, thanks.
Thanks. Should I have covered how to secure Node Red and MQTT when you expose your Pi to the wider world?
This video provides more n more information, when you see it repeatedly.i am new to raspberry Pi. but the information i got from this video is enormous. thanks a lot -:).
Thank you. Really glad it's appreciated. I wish my kids spent more time thinking about my emails, Twitter and other postings but like the rest of the world everything is SO shallow :) Good luck and enjoy your adventure with the Pi and thank you for your feedback.
Holy crap dude! You are one of the best teachers I have ever come across. Thank you so much!
I appreciate this - thanks.
I could listen to you read the phone book! What a great video!
Years ago, my dog had her own entry in the BT phone book. Thanks for your feedback.
Totally blown away. Extremely concise. Also subscribed.
Great stuff Richard, many thanks...was able to work through all the examples with your clear, detailed guidance.
Looking forward to more of your tutorials/info-packs.
Thank George - what are you thinking about doing? I'm playing with IoT.
A really good introduction Richard. Many thanks.
Opps - wrong link - shouldn't really be pressing the 'Like' on my own video - but thanks Dave for your comment and Merry Christmas and a Happy New Year to you too.
I'm reminded a bit of the narrator speaking whilst a potted plant and a whale careen toward a planet. And I enjoyed it! Thanks for the info!
Don't know why I have only just seen this comment but it made be smile. Happy New Year Mark!
Very impressed with this video, in fact I have shown it to several others. It has given me food for thought of how to proceed with my homebrew custom IoT solution and MQTT
Excellent - keep us posted as to how you get on.
Outstanding, clear and appreciate you creating and sharing. Love the classic game sound.
Much appreciated. Thank you.
This is very informative . as a beginner on this subject I now know an end to end perspective- very effective visuals and presentation- thank you sir...
Thank you Ramesh - good luck with your 'playing'.
Awesome! Followed exactly as you went through the process and works great on my Raspberry Pi 3! Very well spoken, detailed explanation. Now I am going to save a copy of the SD card as to not have to do this again for another Pi setup!!!
Thank You
Thank you for your reply - this video was borne out of the frustration of problems with differing versions of the component software. It could be an idea to store a copy of this image online(?). The other option would be to start with a minimal installation and use Git just to install only the required components which is quicker. This route took time and installs everything which is good thorough option for 'newbies' I presumed.
Fantastic video, everything works as expected even >2 years later
- that's more than me I'm afraid :)
Well done introduction to Node Red and MQTT. I'm looking forward to your follow-on video.
Thank you.
Best intro I've ever seen thank you!
Thank you.
i like your clear way of explaining things. Great work Richard , thank U verry much !
Well thank you both - keep me updated with your achievements please.
It cannot get any better. Thank you for the wonderful video.
Thanks Vijay
Richard rocks! Thanks for such a good Node Red RPi tutorial.
Cheers - don't forget this though ruclips.net/video/z9a_ztJqaII/видео.html
awsome
Thank you.
Thank You. This was an excellent intro into Node-Red. I wish I had watched it before I spent time on my inexplicable errors!
Thanks Gary - there is merit in struggling :) Happy New Year and sorry for the delay in replying.
Wow...an excellent tutorial,well done Richard, can't wait to get stuck in !
Thanks and good luck!
This was totally 'gold quality'!
Very well done, very good script, very good narrating, very pleasant voice and accent, and by the way, you should do audio-books for a living, if you are not already doing it
:o)
Liked, commented and subscribed.
Constructive feedback: the only thing I would lose would be the repeating audio separator (i.e. 37:22).
Again, five stars for your work.
Thank you very much!
Thank you. I appreciate your comments. Makes it all worthwhile.
This came on in the background and I thought... what on earth is Jeremy Clarkson doing on a Raspi channel! So i quickly found this tab to see. Its unbelievably canny. wow. Thanks for the vid too.
Life on the internet and serendipity eh? Cheers.
Great data and great to listen to! Subscribed.
Thanks David - it's appreciated.
A big bow to you !!! this is wonderful ...... cannot thank you enough
Best ever MQTT explanation!
Thank you.
This is the most complete, well presented and useful video about NodeRED I've ever seen! I think it should be placed on a central place on nodered.org. Thanks for sharing :)
Wow - thank you. This makes everything worthwhile.
Quite enjoyed the narration, reminded me quite a lot like the game "The bards tale". At some point I was expecting to be insulted.
Bravo :)
I can do insults - but that's an extra :) Happy New Year and sorry for the delay in replying.
Very clear instruction. Enjoyed the narration too! Thanks
Thank you.
Excellent!! Very clear en comprehensive explanation. Thank's for sharing this.
Great video... very clear and still relevant. Thank you!
Simple Superb .... You got lot of Patience Richard Wenner , Thanks a lot
awesome video... well presented and great voice over... first time finding out about node red :) :)
Smile mode on - thanks!
Wow, Richard you did a wonderful job explaining everything and making it look super easy. This is much easier to use than Arduino's "Processing" language (even though it's still helpful to know). Thanks!
Ah I did enjoy Processing but my students saw it as a backwater. Thanks for your comments.
Excellent video Richard! Thank you a million for that! Keep up the good work!
This means a lot Jaroslav - thank you.
Great video. Thank you. I made the mistake of trying to get mosquito running on a fresh install of Stretch. Cost around 3 days of head banging before going back and digging out the latest Jessie and starting again. All now working and talking to an ESP loaded with Sonoff-Tasmota. Problem is that mosquitto is dependent on some libs that have been dropped in Stretch. Some say that getting this lot working and then upgrading to Stretch does work but I have not tried. Mike
Mike This is all part of the fun of Linux .... Open Source ..... you feel f***ed it took so long but GREAT when it works .... thanks for your reply - let's know how you get on
Somewhere I've a video of pure exasperation ruclips.net/video/Y4Nka-jbHCY/видео.html you can hear my despair - keep going!!!!!
The voice and the explanation is really wonderful.
and your typing is impressive too!
Your video was the major source of information on Node-Red for my final year Engineering Project. A huge thanks for that !
Well this is really appreciated - thank you for letting me know. All the very best with your career (I'm, of course, assuming everything went well ;) ).
Excellent ! Very well done and incredibly informative. Great jump start for me on my path to IoT mastery from basics. Subscribed & Thank You!
Well thank you for your feedback. Sorry for the delay in replying. How did you get on?
Great video with such much useful and exciting information. Thank you!
Thank you.
Richard, terrific video, really well done!
Thank you John.
Crisp and clear.. Thank you so much!
Thank you. Have fun.
In 2018 the best thing so far is to subscribe to you site
Outstanding! This is THE tutorial. Many thanks.
THE thanks from me :)
Nice, clear, valuable information, great Job !
Thank you. There is an update for the update (as it were) ruclips.net/video/z9a_ztJqaII/видео.html

Awesome tutorial. Very useful tutorial. Thank you sir. I have just started working on iot. Hope i will learn lots of things from you.
Thank you. Do have a look at ruclips.net/channel/UCu7_D0o48KbfhpEohoP7YSQvideos He is a joy!
Fantastic video, will share with others!
Thank you.
thank youRichard. These tutorial was really helpful for me as a beginner. Hope you much more tutorials.
It's great being a beginner - so much fun to come!
Hello Richard, long time no see. I was just looking for some info on MQTT and saw this!
Yes, long time, no see. I hope this is of interest. What are you up to these days?
Wow this is incredible. Genius!
I want your babies!
Great intro, thank you! I could listen to you forever, can you please record an unabridged read of the Hitchhiker's Guide to the Galaxy? ;)
Wow - two classics that can never be repeated 'Hitchhiker's Guide' (Radio Version) and 'The Prisoner' (ATV 1967)! (Oh and possibly 'Tales from the River Bank' Johnny Morris - in fact anything by Jonny Morris). erg - what have you started here? Thanks for the comment. :) (This is going to be a mind-worm for the rest of the day! -Damn you sir!)
OMG, the presentation was amazing! Instant Subscribe!..:D
Hopefully I will find time to do some more - this is getting a little old. Thank you.
Beautifully explained. Thank you.
Thank you again Thomas! :)
I needed this for work, thanks alot!
Work? Playing with Pis is pure enjoyment. You have a great job. Thanks for your feedback. It's appreciated.
@@richard_wenner I started working at a real life escape-room company in my town, and we produce our puzzles by ourselves, including the usage of node red, so this was very helpful to me. :)
Richard well made video I enjoyed watching Node-Red
Thank you, really enjoyed the video. Its a fantastic way to learn so professional. I am now going to give it a go
brilliant - it will change and take your life! :)
Sensational video, many thanks!
Thank you.
Amazingly awesome tutorial! Great job done...
Thank you.
Superb description!
Thank you, Peter.
Excellent article and nice presentation.Thank you!!
Thank you.
I follow Andreas Spiess videos... i am surprised to see his comments here... Speechless.. Thank Q
I drove out to spend a wonderful day with him and have met again whenever possible. I was really pleased to arrange for him to come and speak at the Reading Things Network event. He is a God With a Swiss Accent as far as I'm concerned.
Fantastic introduction to Node-Red, thank you! Liked and sub'd!
Thank you.
The most exciting software environment.......in the WOOOORLD!
:) and I'm sure there is much more to come and be developed.
Sir. You got me inspired… I am setting this up right now. Thank you!
That's pleasing - thank you.
FYI. I successfully completed the setup last night, including Mosquitto. I can access my Pi’s Node-Red from within my Lan without any issues. Thanks to you.
Excellent - now secure both Node Red and Mosquitto - with passwords - and using the secure version of Mosquitto (if you are going to put this on the Internet and also see Peter Scargills work with Node Red
I’ll get to that immediately, thank you.
Subscribed. Quality stuff.
Thank you.
Thank you for a great starting point. The many building blocks of the Node Red world are now a bit more understandable.
thanks this exactly what i was looking for. liked
Thank you
Very good and useful presentation Thanks
Thank you.
Anyone here in 2021 feeling like they've been living under a stone? Lovely presentation style
Plenty of time to play though? Thanks Richard
@@richard_wenner The great illusion in the digital age is that somehow one has missed the boat. The IOT boat has yet to even begin boarding really. Exciting / scary times
