This is the only video that showed me enough detail to get my node red doing what I want. Very good mate.SUBSCRIBED.

[@tampatra]

That's one hell (or something nice word) of information/work/insight over a very complex/broad topic in a very short video. Please keep up this good work.There is a steep learning curve for all those subjects, discussed here, and I wish all viewer/enthusiast DIY'ers are willing to pay time. I'll certainly not miss any past/future post from you on this very topic(s). Once again, Thank you & wish you good luck...

[@mvitalik111]

We love your videos and Fran's voice! From Canada

[@Hasitier]

Nice video. Please do more of the home automation MQTT stuff. I have my own raspi broker with node red, set up with the script from peter scargill. I use some modified sonoff switches as actors to switch lights etc. Works great but your videos gave me some nice ideas for functional improvements. Thanks a lot.

[@bitluni]

peter scargill is truly a reference...

[@chuxxsss]

Nice work on Node-red. You may find using big-time from Peter Scargill handy as well. I for one was real impress with the function stuff. I need to work on a filter for picking the right switch in node-red. As using ifttt and dataclicity makes it harder to access the right switch for some reason.

[@bitluni]

+Chris B have to check ifttt soon. Google home mini just arrived

[@DAveShillito]

Thanks for a really useful overview video, especially showing the dashboard.

[@lightdark00]

Going to have to rewatch this on a full size screen... Hope to see projects not requiring a broker or server, maybe just a memory card for data storage collection and solar powered with a battery backup. Truthfully, that's what I make mostly, I wanted to see concepts and ideas from you 😊

[@bitluni]

sorry... mqtt broker needed. (you can use io.adafruit) It's just much more convenient to process the data using node-red. other features are given :-)

[@tangosierra41]

Great video and my first subscribe. Learned a lot this evening! Thank you

[@fernandolunadev]

Excellent tutorial about Node-RED. Thanks a lot for the time and dedication You've put on the project and the video. I'm so grateful! I hope some day can have a time to try Node-RED with your tutorial. Regards!

[@StePhanMckillen]

Nice thanks for taken the time has open my eye to node red thanks again and you can say "minus" ok with me

[@soulife8383]

The bad guy from Die Hard took some valium and then decided to make a Node Red educational video? Awesome!

Thank you for the insights... Very useful for many other applications.

[@edgaraguilar8555]

A lot of information very well presented

[@EkelundDK]

Very nice walkthrough. Great job!

[@petrbrazda1064]

The Guy with the Swiss accent I supose :-)

[@lyphuong]

Great! Node Red working

[@bigmistqke]

Very cool technology

[@RishiRajKoul]

Very good video. Can you guide as to how to setup node red on a PC windows or linux to use it as broker with the multiple devices using 4G sim card each for connectivity. How will node red send a control message (like switch on ) back to device over 4G connection

You are the king. But, A video that explain how a non-local secure access can be provided makes you lord of the rings :)

[@bitluni]

You could always use some dyndns service and adding port 80 (or any ssl port) forward on your router. But I'm not sure if I would ever like to have my appliances exposed to to the web.

[@RadionicaExpress]

Great video

[@uweri_3851]

thank you for these nice tutorial. For me very helpful. Hope we get more

[@anekoueifard]

thank you for your great educational video. Could it possible to connect red-node app on mobile via the Internet? You have connected to it via mobile through the internal network(local host)!

[@jonagostini8782]

Thank you from California!

[@mandeepmails]

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.

[@danielergawanto4170]

it is only work if our device is on the same network? i.e same wifi in our home? or it is can access from all over place (public network)

[@grindel80]

Great and funny as always. BIG LIKE

[@RaulAlexandreMatos]

Can I add a new device dynamically in node-red dashboard?Thank you, it's the best beginners video about node-red I've seen!

[@elaatermohamed4961]

thank you for the tutorial !! i'm just for the complet method to publish my dashboard in a local network, so i can access to the dashboard from my phone or other laptops connected to the same network

[@timkrav843]

wow super cool! Can you possibly do a tutorial on how to ad a LoRa device to the things network and then control it?

[@codersindonesia]

Nice to know. Thanks its very useful for me

[@alfonsozarzasanz593]

Hello good morning. I have made a code in which I receive a message from two IP devices, and I save them inside a folder. The problem is that for this program to run, I have to open the console from the PC. Is there a way so that, simply by turning on the PC, the program will run? In other words, without the need to search for the console and open the program manually. Thank you.

[@akado5663]

Great Job. Very Helpful. Thanks. The only issue which I could not fix it was the MQTT Broker. as I followed the Video everything was fine but by connecting to WeatherStation/# it could not connect to MQTT Broker. should it be separately installed?

[@themerpheus]

I am thinking about industrial automation via industry 4.0 concept considering this.

[@predragristic6003]

Great job man!!!! This is so great. Thank you for this great tutorial.

[@kevinvdb13]

Whoo new video! :D. Do you perhaps do something with Home Assistant as well?

[@alphonsebenedict4327]

Nice video sir

[@ramazans8114]

thanks for great tutorial

[@spacefolder]

Hi Bit Looney! Great, informative and humoresque videos as usual. Quick question: Is there any way of accessing the dashboard from outside the LAN, without opening ports in the router? Cheers!

[@bitluni]

I don't think so. Either opening the port or using a v-server outside your lan with node red (but this would require another mqtt setup).

[@jyvben1520]

if your router supports vpn, you can (if you use dynamic dns or have a fixed wan ip for your router) vpn into your network an then open the webpage of the nodered service.

[@samiratalebi7803]

Hi, danke für Video. Ich hab eine Frage, zum Energiemanagment kann ich Node Red benutzen? Ich möchte Daten von Geräten zuerst speichern dann visualisieren.

[@khaledtifoura2973]

Great !, simplified explanations,very interesting, thank you.

[@AMoktar]

thanks a lot

[@dariovicenzo8139]

Great video! How Node-red is different from OpenHAB. I'm a little confuse! Thanks

[@haus_automation]

Ich habe schon sehr viel mit FHEM umgesetzt - allerdings werde ich wahrscheinlich FHEM demnächst mit Node-Red ergänzen. Also dass FHEM nur noch die ganzen Geräte verwaltet und alles über MQTT übermittelt. Die eigentliche Logik würde ich dann gerne in Node-Red abbilden, da ich dort alles wesentlich schöner gelöst finde. Zusammen sind die beiden sicher ein sehr gutes Team :)

[@bitluni]

Zur meiner Schande muss ich gestehen, dass ich FHEM gar nicht kenne... bin echt noch ein n00b. Aber kommt sicher noch :-)

[@haus_automation]

Is klar :D Du setzt auf deinem Kanal wesentliche komplexere Themen um ;) Finde das hier wirklich alles super spannend und werde auch ein paar Dinge in jedem Fall nachbauen! Danke für die ausführlichen Videos und spannenden Themen!

[@bitluni]

ich weiss zwar nicht alles, aber wenn mich was interessiert dann verschling ich da alles wissen und probiere gerne was aus. Momentan kämpfe ich aber viel mit Administration vom Kanal und so. Ich versuche jetzt wieder langsam wieder etwas komplexere Themen zu behandeln, ohne die Leute abzuschrecken die noch neu sind. Wünsche dir auf jeden Fall viel Spaß!

[@haus_automation]

Hehe, ja das kenne ich :) Ich verstehe Menschen nicht die Langeweile haben - es gibt so viel zu entdecken, zu lernen und zu probieren. Ich wünschte die Tage wären länger :) Freue mich auf jeden Fall schon auf weitere Videos von Dir!

[@Empusas1]

What about an IR Blaster with the ESP8266 for the next home automation video?

[@bitluni]

+Empusas1 waht is a ir blaster?

[@Empusas1]

Hallo, mit einem IR Blaster bezeichnet man ein Device das IR Codes senden kann, Blaster deshalb weil oft mehrere IR Dioden drin sind um die Leistung und damit die Reichweite zu erhöhen. Also ich würde damit anfangen mit einem ESP8266 Board und einem IR Empfänger die IR Codes der Fernbedienungen aus zu lesen. Software dafür gibt es. Dann einen Webserver mit einer REST API auf dem ESP8266 laufen lassen der die IR Codes in der URL annimmt und dann per IR Sende Diode sendet. Software dafür gibt es auch schon. Interessant wäre aber sicher die Elektronik, ein oder mehrere IR Dioden am besten über Transistor angesteuert da eine IR Diode direkt an den IO Ports zu wenig Leistung bringt. Sowie die Integration in Mosquito, Openhab, usw.

[@TheHappyKamper]

@@bitluni IR = Infrared Radiation. Basically he wants to send infrared signals from a remote control (like the one used for you TV). This would be useful for automating and simulating a universal remote setup.

[@jorgegabrielar]

when I type my pass it says password denied. I followed through the entire tutorial and now I cannot access my RPi. help!

[@MU3LL3S]

just amazing, thanks

[@johnz.2957]

can this Node-RED project be used by a beginner user?

[@wjhoogervorst]

Thanks, great video!

[@marcschneiderphoto]

quick question as I'm new to the whole MQTT and Node-RED thing: do the used systems also save data transmitted from a node (e.g. your wheaterstation)? And how is that data accessible?

[@thomasamsterdam]

Great tutorial. Just a little remark. The .node-red directory will not be there, until you start node-red for the first time.

[@desy666]

Hi, how do you do the gauge-level for the humidity in that shape? The blue zone is a straight line to me :( and what about the light with the sun? anyway thank you, I found this video really usefull.

[@himalayanapiitech2311]

Hello thanks for video ... can you make video on control multiple esp8266 mqtt on node-red and is there any thing we can add new devices from ui????

[@goldstarit]

Wow~ Very nice!

I thought "node red" is some kind of IDE for node js... i did not even open it since i bought my raspberry pi... today i will open it....

[@RelyingArcher27]

Hi, can i use esp32 make mqtt server? And how to make it? can you teach?

[@rkdilla]

what is the hardware used for the lava lamp? 8:50

[@MrJanulis]

I guess you know about Big Timer node? It might be useful for washing mashine automation?

[@bitluni]

nope.. link?

[@lookboy478]

Hi, I have a question for you: Can I edit node’s properties from functions? If is this possible, how can I do it?

[@yusofjohan3456]

hello i have a question. can the raspberry pi and nodeRed read vibration sensor values on the dashboard?

[@smickinfo1991]

hello luni I tried the audio node. It works on PC, but on my phone's Chrome browser only pop-up "Computer says ..." message pops up and no audio is heard. Do you need to configure something on your phone? thank you

[@samot56498]

This work only on lokal area network?

[@leandrocosta4283]

Hi, I'm in doubt about using openhab2 or node-red. What did you tread your way to nodered?

[@DrinsterTV]

Nice video bro :) Did you have a link for the time picker code?

Try middle click to paste

[@maxkremmel]

can someone explain me how the code in the template node (Data Input) works? I copied lunis flow and used it in my projekt but my time is fals by one hour. So i tried to understand the code to evantually change the timezone but no chance

[@tapiraiverde]

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?

[@nayabinlam]

Hi I want to know if there is something similar to node red but for Arduino or Nodemcu (esp)

[@usmanasghar2567]

You are awesome

[@zephalon]

Vielleicht bin ich doof, aber wie bekomm ich folgendes hin: ich erhalte eine MQTT Nachricht mit Payload '1'. Dann will ich umgekehrt '0' auf einem anderen MQTT Kanal schalten.

I make the wheather station using rasberry pi but problem is i am not saw at mobile how you do it this plz tell me plz

[@jasonliew2678]

Why I can't access to the ui dashboard via my phone even though I insert exactly the same Ip address to my phone browser?

[@ZsomborZsombibi]

Heh, I see you use the pico editor. Good man:)

[@poweredbysergey]

Nice

[@cch4433]

Very good but missing how Rasp PI connects to these sensors.

[@alchemistalchemist6051]

The raspi hosts a MQTT broker, that the sensors send messages to and the actuators read from

[@jonathangerard745]

Hi Sir, I just nlove watching your videos. But I kindly request you to make s separate tutorial on the function node of Node-RED and also the basics of Javascript. Thanking You, Yours sincerly, Jonathan Gerard Joseph J :)

Can i make it on r pi zero w?

[@user-mfsc-2024]

is node-red installation come with mqtt broker?

[@HenningAndersen]

@@Adam-vp5lc Wow thats quick, thanks! =)

[@user-mfsc-2024]

where is the mqtt topic configured in node coming from ?

[@nautitard]

Did update-nodejs-and-nodered which failed during installation. Now I get "Bus error" or "Command not found" on every command. Can't connect through SSH either, can only "use" the previous session but this rendered my Pi completely useless until hard restart by pulling the power. After this, the update-nodejs-and-nodered disappeared.

[@bitluni]

did you have a clean image before?

[@jkk2000jk]

I have a question: How do I leave a loop, that is running as a function via WiFi. E.g. i write my function in the beginnning( a simple blink with a while(true) loop). Now i upload it and type my ip adress and e.g. /blink in the browser. But now i have the problem, that i can't access any other function, because the blink one is running and the server doenst update anymore.

[@bitluni]

If the editor does not react stop the server or reboot the device. I don't know of any quick way to cancel an endless loop in the function. However if you have created a message loop by connecting nodes that trigger each other infinitely you still probably can remove a connection and deploy

[@jkk2000jk]

bitluni's lab my solutions was to connect two microcontroller and one recieves data and can start loops and the other one can still change the input

[@ankitvirla]

how you open node-red dashboard on your phone?

[@DirkTas]

I tried to import the weather station flow from your webpage, but I can not press the import button. Any idea ?

[@bitluni]

Thanks for the hint.. somehow wordpress messes with the text... it should work now. Please try again

[@xlfvrs17]

Do you need a Raspberry Pi for each of the examples? (e. Washing Machine, Lamp, Temp. Control).

[@jonathangerard745]

Well, Sir, you may use other Linux devices such as Beaglebone, or use your regular Windows or Mac computer. You can install node-red on windows and mac manually via the npm. But you have to install node.js
