Quite simply, the best Node-Red instruction available, thank you for taking the time to create all this content. You have a rare gift to demonstrate, explain and educate.
Thank you for taking the time to watch! Are there any other topics you'd like to see us cover?
Even in 2024 the best tutorials of node red. Thanks a lot!🎉
You are the best for Node RED tutorial.
Thanks Joe. We think you're the best!
Excelent video. I love your Node-Red instructions. These helps me to implement more functionalety into my flows. Hope we get much more from these tutorials.
We try our best, thanks. Any suggestions for future videos?
Of course (-;. I have implemented an Node-Red flow (raspberry pi) with connection to an ESP8266 over ESPEasy / MQTT. In the flow I see that ESP8266 is sometime status switch from MQTT connected (green dot) too MQTT disconnected (red dot). I do not understand how these works in detail. Would be great to get more information about these connect/disconnect status.
Thank you a lot for this tutorial! You have combined so many knowledge in just one video. Great tut!
Underrated channel ...Nice work guys
Thanks IOT Academy!
I really came for that 'Music' initially. Then everything I started loving from UX, Colours used, Explaination, Examples, Flow, etc.
i love that track also. Is it a free use yt jingle?
i am only here because of this intro music
This tutorial. I cannot thank you enough!
You're very welcome!
Great presentation
Thanks, one day I will suss this stuff but this has helped me along my, oh so slow, journey, thanks again.
excellent tutorial.Thanks!
Glad you enjoyed it!
Very good intro to Node Red, thanks
We appreciate your support.
This was perfect!
Thanks Ariel!
thank you dude,
very helpful intro :)
Happy to help
Brilliant Video! Thanks!!!!
Glad it helped!
Great video ....thank you.
Thanks Phil! More videos coming soon.
Thank you :D
Thanks for positive feedback!
Thanks for the video =)
No worries!
Excellent video as always. You have a knack of explaining things very well.
Would love to see a video of you using NR to drive some modbus TCP outputs, read inputs and create some data sources driving the outputs.... If that makes sense lol
Thankyou for the feedback, we'll see what we can do! For modbus devices I've been using the `node-red-contrib-modbus` package, if you're looking into modbus communication using NR that's a great place to start.
Opto Video is modbus to point Mqtt messages to Nodemcu for example
I’m grateful to see such an elaboration. Hats off to your knowledge and presentation skill. Undoubtedly I’m newbie into this, and exploring all I can, may be you could point me to the right place, if there’s a guide to get expertise over nodered. I’m still unable to correlate some basic stuff sometimes...my first project I’ve decided is to have complete dashboard for my room lighting controls. I’ve already bought one Nodemcu.v9 and got raspberry pi able to use gpio pins. But not over wireless MQTT.....please advise me. Thanks in advance.
Hi, I have a question for you:
Can I edit node’s properties from functions? If is this possible, how can I do it?
I am using node red in home assistant. I have a Shelly switch connected. Is there a way for node red to perform different tasks for single press, double press and so on...
Hi
I would like to copy modbus read value and add or subtract one delta value and keep this result value till bolean input goes false, whe it goes false it return back to the previous value readed before bolean true. Is it possible to do with RBE node?
Thankyou!
how packaging he used in the video?

I see that the email node is not in my palette. Odd, I thought, for a video on "core nodes". It seems that Node Red removed the email and "Social" from core functionality. Searching, I see that I can manually add email to my palette.
Is there maybe a good reason this node was removed from core install? Is there some better equivalent, now that ~5 years has passed?
from openweather I have taken the sunrise n sunset time and try to convert n the readable format , it is getting convert but date is coming form 1970, please help in doing so
is node properties in switch got deprecated? I cant see that option..
8:49 Sorry, i don't quite understand this part.
He used the switch nodes as if else statements, but after he deploys it doesn't show in any way that it's weekday or weekend.
How would i find out if it works?
Change the Name property on the debug nodes and he name will be displayed in the debug messages instead of the long hex id number.
Just use the BigTimer node
The BigTimer node is a great option, but that does require an internet connection to download and install first. A lot of Node-RED applications can be in limited-access or entirely closed networks, where the preinstalled nodes are essential.
Sorry man, i've got this error concerning the email node and the send is failed: "Error: getaddrinfo EAI_AGAIN smtp.gmail.com:465"
I followed the video step by step, everything worked perfectly, except this. Please i really need help!
Apart from that , really NICE JOB!
a thing i noticed is that, as you did, i put my userid and password in email node and click done, but when i reopen it there are less characters than before in the password field. I don't know if is this the problem or maybe my password is too long and few black dots are showed
`d = new Date()`, seriously?
What language is that, javascript from Netscape Navigator?
Man, if you say in one video that node-red speaks JS, it's assumed that it speaks it well. Does it?
The pace of your video(and your voice) is too slow.. I have to set the playback speed to 3.0x.
Hi John, we strive to make content that is accessible to as many people as possible (non-hummingbirds included). Thanks for watching!
It needs to be slow, it's very complex. I have to keep pausing.
