@@notenoughtech Sorry where do you source the hardware buttons from. how do they connect to the server ? is that by means of a zigbee or lora gateway / hub
@@jasontodhunter9088 there are many buttons you could use. I go for zigbee based system which need a zigbee coordinator (I have some articles about that) but you can find BT based stuff or even WiFi
Can I use a VPN to access my node-red-server from the internet instead of opening a port? Or will I have limitations with how I construct flows by using a VPN? Love your content. Thanks for sharing your expertise. I agree with others you should consider making your terminal fonts larger.
Thanks for the font suggestions. Even if you use a VPN you will need to open a port to connect to NodeRed. From a security stand point I'm not sure what it more risky having a port open for VPN or for Node directly. Both will need authentication so as long as you use strong credentials you have done everything you could yo keep yourself secure
@@notenoughtech As a noob, my understanding was that running a VPN server on my home router required no open ports to the internet. When tunneling into my home network via VPN from the internet, I access node-red-server with my local address (eg 192.168.1.xx:1880). That 1880 port is not exposed to the internet accessed via VPN. As I said, I know just enough to be dangerous coupled with the illusion of competence. ;>) Tnx.
You will need to open a port to the VPN sever - how otherwise will you access the server behind the firewall? :) You are tunneling via specific port :) By default you have a number of ports exposed by your router for communication already - opening ports isn't equal to making your network vulnerable but not securing devices behind it is.
Each video comes with an article in the description, where the commands are listed so you don't have to pause the video to figure out what to do :) This way you can take it at your own pace
Yes you can use it on any of the Pi (advantage of better board is faster interface and more memory) - nodered.org/docs/getting-started/raspberrypi Here is the current way to install it ... but you can opt out for docker as well.
thank you! very easy to understand & follow along. i think i understand it more clearly now.
Awesome thanks
Hi great intro video where do you get your node red buttons.
What do you mean I'm sorry?

I have question and forgive me for my ignorance, Is it possible to use same Pi for both mqtt broker and as a NodRed server ?
Yes, the mosquitto will run in the background while creating endpoints for NodeRED
@@notenoughtech Thanks for answering and you are doing great job :) . I admire you
Thank you
Awesome videos! Get a better mic when possible. It'll make a big difference.
On my shopping list! I think next month on Patreon should give me enough to browse something decent
It will be helpful if you make a tutorial how to deploy nodered instance in ibm Watson cloud and connect with an Arduino
You can use MQTT if you have an Arduino connected to the internet

Screen seems all blury when you show the node red screens.
Thanks for the tiny terminal. Best to keep fonts as small as possible.
But you can CTR+scroll up to increase the font in chrome of the attached article to your heart's content
Great info, but you REALLY need to show the terminal window full screen. You are moving a bit quickly and the tiny type is impossible to read.

I suppose "getting started" would include "apt-get install nodered"
It depends on the actual device you are trying ok it on. On the raspberry pi there is a bash script
@@notenoughtech You "started" on a RPI zero, right...
