NodeRED for beginners: 2. Getting started

[@zenyrgarden7859]

thank you! very easy to understand & follow along. i think i understand it more clearly now.

[@notenoughtech]

Awesome thanks

Hi great intro video where do you get your node red buttons.

[@notenoughtech]

What do you mean I'm sorry?

[@jasontodhunter9088]

@@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

[@notenoughtech]

@@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

[@TheEyupalkis]

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 ?

[@notenoughtech]

Yes, the mosquitto will run in the background while creating endpoints for NodeRED

[@TheEyupalkis]

@@notenoughtech Thanks for answering and you are doing great job :) . I admire you

[@notenoughtech]

Thank you

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.

[@notenoughtech]

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

[@quaternion-pi]

@@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.

[@notenoughtech]

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.

[@Arbiter5154]

Awesome videos! Get a better mic when possible. It'll make a big difference.

[@notenoughtech]

On my shopping list! I think next month on Patreon should give me enough to browse something decent

[@mamartyacse1]

It will be helpful if you make a tutorial how to deploy nodered instance in ibm Watson cloud and connect with an Arduino

[@notenoughtech]

You can use MQTT if you have an Arduino connected to the internet

[@ismzaxxon]

Screen seems all blury when you show the node red screens.

[@Harrzack]

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.

[@notenoughtech]

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

[@good2gogo1]

Thanks for the tiny terminal. Best to keep fonts as small as possible.

[@notenoughtech]

But you can CTR+scroll up to increase the font in chrome of the attached article to your heart's content

[@hammershigh]

I suppose "getting started" would include "apt-get install nodered"

[@notenoughtech]

It depends on the actual device you are trying ok it on. On the raspberry pi there is a bash script

[@hammershigh]

@@notenoughtech You "started" on a RPI zero, right...

[@notenoughtech]

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.
