Easy MQTT Server Setup

This simple tutorial shows how to setup an MQTT broker on a Raspberry Pi. MQTT is a little bit explained and some examples are shown. It is also shown how to add password protection and get es fixed IP from a router.
Links, code etc. can be found on the project page:

So FYI, you don't need a mouse and keyboard and monitor to setup the raspberry pi. 1) create your SD card Raspbian image 2) . create an empty file called ssh in the root of the SD card boot partition. This enables ssh on first boot. 3) Connect via ssh from your computer, saves you a lot of hassle...

[@xxaax]

cool thanks! saved me alot of time!

[@webblab2415]

​@@xxaax don't you forgotten a network connection? I mean wpa_supplicant.conf file with ssid ad pass....to allow raspberry to connect to the LAN..

[@richardlighthouse5328]

@@webblab2415 Not needed when you are using ethernet, which you should be using anyway.

[@cavhaunch3597]

How do you know the ip address of the pi before connecting it to a monitor?

[@thenetimp]

@@cavhaunch3597 I don't. I use other unix tools to scan my network for new devices and their IP addresses, typically the new PI is the new one. Or if it's an older pi I am setting up again, I have the mac address recorded on a piece of tape on it for future reference, I can set it up in my router to have a specific given IP address.

[@BrianThomas]

3:58 The default IP address can be found also in the raspberry pi after running ifconfig. Generally the default gateway is the router or where the IP is being generated from. Type in the default gateway IP into a browser and you should be prompted to login to your router.

[@zvpunry1971]

6:11 The config file contains "include_dir /etc/mosquitto/conf.d" by default. It is a good advise to use this to just create a file like "/etc/mosquitto/conf.d/50-bitluni.conf" and add your config there. When the mosquitto package is upgraded, it won't ask if you want to keep or discard changes on a changed config file. And you have all of your changes in a single file with clear visibility of your own deviations from the default. Many other programs have something like this in their config too.

Yep love the home automation and so happy your back making videos one of the best on youtube.

[@mmajstruk398]

Hi! Another great video that saved me lots of time setting up my Raspberry Pi with MQTT broker for my academic project. I got Raspberry Pi with Node-RED and MQTT ready, now it`s time to get ESPs, sensors and relays out from box and start playing with them - that should be the most fun part of project ;) BTW, I liked the password ;)

[@sairfan06]

What user interface you were using for mosquitto like 192.xx.x.x:1992

[@TrentSterling]

Was subbed, but today I added the bell. There's a lot of devices around here I need to chuck an ESP into. Looking forward to the washing machine project!

[@ajaybnl]

I love when you do over acting.... Thanks.

[@bitluni]

Thanks mate :-)

[@Noah-vm8id]

Echt mega hilfreich, bin schon am Schauen wo ich meinen Raspi habe, das wird sofort umgesetzt

[@arunbm123]

You have so many components in shelf...Good Setup !!!!

[@xxaax]

Hi bitluni, thanks for showing us the setup. How would you proceed, building a new house? I like the mqtt node-red technology and think it would be a cheap solution for a smart-home. Are there any good guides out there yet? How to wire everything up and so on. Thanks again, and keep on basteling ;)

[@sntshkmr60]

I can't open the dashboard from my host machine's chrome. I have installed mosquitto into raspi using ssh.

[@istvantemerdek3445]

Good password for mosquitto :)

[@colinpamplin9976]

Very interesting I think I will add password to my mosquitto Pi3 setup with 12 mqtt devices. I have found node-red very good and easy when you get the hang of it. The only issue is the dashboards can be slow with several devices, graphs and dials.

[@bitluni]

I like node red.. planned to add it with the first use case :-)

[@gcm4312]

nice password 🍈🍈😂 oh, when you want to mask mac addresses, it is better to mask the last 3 bytes since the first 3 are usually used to identify the manufacturer so easily discoverable if you show the device on the video ;)

[@carlosvidal3814]

I just rewatched the video and thought, "wait, is he showing us the password on purpose? That has to be a joke" and I was right 🤣

[@KshitijDhar7]

Awesome! Was looking for this. Thanks :D

[@shinevisionsv]

Lmao, the washing machine fix is genius.

[@transient0126]

LOL..rev 1 never used with dust all over it. You and me both mate...you and me both :D

[@BeanedVR]

Thx for the helpful vid, also great user password ;)

[@Noah-vm8id]

This video is also a good example for the fact that german humor does not work in other languages

[@JasonRobards2]

excellent tutorial!

[@BrijeshRana]

5:36 I see what you did there 😂😂😂

[@andironner6784]

Why would you need security, it's all within your network.?

[@leon-set]

Bruder genau was ich brauche 👌🏼

[@tinker7722]

MQTT is so great! wow - I like it!

[@tinker7722]

Thank's for that info! this way I do not have to plug my raspi to my TV-Screen

[@VBsepheroth888]

Does mosquitto not work on the newer versions of raspberry pi? I have a pi 3 model b and I can't get mosquitto to install to it.

[@zephalon]

Nice video! I want to build something similar but I already have a RF24 hub so my sensors don't need a WiFi connection.

[@bitluni]

+Zephalon coming back to rf in a few weeks

[@yusofjohan3456]

what if im just using a mobile phone hotspot? should i change also

[@MrBobWareham]

I hear the SD card in Pi don't last very long something to do with read-writes so can we use a hard drive to the pi or another small computer please thanks Bob

[@AhmetTasdemirDJLuds]

İ was tried it last year but it worked only with local broker. Am i true or false ?

[@BrettSeibert]

i just get "unbindable key" trying to save config

[@jonatasdeoiveirasousa595]

If a don't have a Rapsberry Pi, can I use a virtual machine Linux instead of a Raspberry?

[@MobiMenace]

Thanks for the videos; they are helpful. Would you please go through SSL setup, please?

[@bitluni]

Ok, I will. But probably not October since I've a full schedule and have to do a project for Halloween

[@marcodibona]

HI! Is MQTT client in PHP possible? which library to use?

[@xbmcnut]

Thanks for the vid. What MQTT app did you use on your phone?

[@bitluni]

MQTT Dash. Works fine but it doesn't support widgets.. if you know any other good ones I'll try

[@xbmcnut]

Yes, I use that too but MQTT Dashboard allows single button widgets although it's not as nice to use.

[@LatinDanceVideos]

I'm late to the party, there are far too many options now. Blynkt looks nice but I'm not convinced it works well with MQTT.

[@msmadaram]

have you ever work on android broker such as moquette or something like that ?

[@gianluca1694]

i have the problem that my PI in the menu not marked as "mos installed".... and nothing connectto anything....

[@MegaSolidgamer]

How did you connect your phone with the ping pong senario?

[@hacihocni6156]

Is there a safe way to access local host in internet ? Usibg just esp32

[@phamtoan3820]

you rock man!

[@roadeycarl]

I don't get it... how to you access the broker?

[@moneydontbuyclass]

will this work with the new raspberry pi zero W?

[@facundonieto1598]

qué datazo el del minuto 3:41! buen video

[@zekrell9381]

6:37 best password btw

[@michaelg.werner4331]

why the ip address of the raspi broker isn't determined AT the raspi itself?

[@schneider1492]

how about running a mqtt broker on a asus router running Merlin

[@AstralJaeger]

Looks verry promising, would be nice if you could explain how we can access these local MQTT servers from everywhere, maybe with somekind of DynDNS

[@gordhenschel1419]

dyndns hasn't been free for years, but namecheap offers free dns and its good. Then forward a port in your router. not sure about the MQTT / Node-RED part. Maybe bitlunislab can comment.

[@AstralJaeger]

doesnt need to be a DynDNS Service, NoIP or something similar should do, would be just nice to be able to check a MQTT based Temperature probe from everywhere not just my own wifi

[@bitluni]

dyndns and opening a port on the router... but that might be risky. If you happen to have a virtual server you could also install a mqtt server on that and let your home mqtt subscribe to that one on the virtual server. it's called mqtt bridge... mosquitto supports it. No open port there

[@AstralJaeger]

The problem with the vserver is that it aint cheap to host one, but i might beworth giving it a shot and look it up. By the way its a good video!

[@caroman6761]

How do I get my communication to the MQTT Broker secure? is there any way of encryption? I heard, usernames and passwords will be sendt as clear text ...

[@bitluni]

didn't do encryption yet.. it's still in your local network. but you probably don't like to use the same password as your gmail one

[@chuxxsss]

You must have been reading my mind. I need to make a new broker for my home. The old one has issues with reverse shell stuff.

[@bitluni]

what is reverse shell?

[@chuxxsss]

bitluni's lab it's where you have a ssl tunnel in to your system without opening a port,

[@narasis]

whats kind of chip is it that plays ping pong?

[@jettaglnegro]

Is posible.... mqtt +android celphone+modem+esp32? Red local...No Internet .

[@umanggoel2709]

My MQTT server is not running. Its giving me an error that address already in use. Any way to fix it? I am a new to linux

[@leonf.7893]

Did you put the correct port in?

[@1q1q1q1q1q1q1qw]

first of all funny videos your acting is great :D i got PRI 1 (c) i inserted the card with the stretch image on it nothing happend ??? any idea

[@___aZa___]

maybe a little late, but did you flash it or did you just put the image on the card per drag and drop?

[@MyTube4Utoo]

Cool......

[@lightdark00]

You show really simplistic computer/Linux issues, but you didn't say how you get the results and settings on your phone.

[@bitluni]

this is the beginning of the series for setting up the server. I'll show how to do the client this week. the app is MQTT Dash.. you add there the broker (ip, port 1883, user and password). On that page you simply add the topics and select the type you like

[@gasca_mx]

First comment! Greatings!

[@user-uv2gu8wm6h]

what is mac address of rasp pi

[@anigamaha]

But what is the other part of the project ; Not the RPi but the little tiny part that is assigned a IP then acts as a remote switch please

[@mrsoundso4897]

Some Esp32 module

[@SIMPhony]

"rooter"

[@AKIRAfotografie]

I did comment already. Got deleted :(

[@bitluni]

sorry had to reupload this one

[@peterjhartvideo]

So dramatic
