Raspberry Pi as a MQTT Broker | Cheap MQTT Broker

In this video, we will be installing the Mosquitto MQTT broker in Raspberry pi and use it locally; this is the cheapest broker you can have. You can use Raspberry pi 4 or Raspberry pi zero, which is affordable yet powerful.

In the last video, we discussed what MQTT is, how it works, and how it was developed. We also discussed the components of MQTT. If you haven't watch that video, Here is the link.

This playlist is awesome! Super easy to understand. Thank you!

[@dangthanhthienan]

It's really easy to follow! Hope you do more videos about this MQTT topic. It would be great if you make a tutorial setting up Raspberry Pi as web server to monitor and control devices through MQTT protocol.

[@HighVoltages]

Thank you for appreciation. Yes, that is my plan, i will be making a complete Mqtt series in which i will cover webservers, gui and android app. Also later in this series we will be using esp8266, raspberry pi, arduino and other development boards.

[@abbas5550]

Awesome! 🙂

[@surendramaharjan3129]

4:49 I can ping my raspberry pi from ubuntu machine but I cant connect using mqtt explorer. port i am using is 1883 in mqtt explorer. I am doing exactly what you are saying.

[@noone7692]

did you get any solution to it?

[@vedantjoshi1487]

Hi, the MQTT explorer application does not connect to my pi IP address (done everything as per your procedure)....can you tell what I am doing wrong?

[@HighVoltages]

There is a mqtt broker running on Pi ?

[@Winkeltje84]

@@HighVoltages I have the same issue. smqtt broker is running on the Raspberry Pi and is on the same network as the laptop. When trying to connect I keep getting "Disconnected from server". Fyi: I am using a Windows machine.

[@sohrabsheykhmohammadi1909]

please write mqtt in java and connect it to cloud

[@wajdibrahem7617]

can i use my RPI as a MQTT broker with KALI LINUX as operating system ?

[@HighVoltages]

you can try and let us know.

[@terryphan1775]

Will this work on Raspian lite?

[@HighVoltages]

yes it will

[@WORLD_PEPITES]

have you a méthod to make a distant broker , not localy ?

[@HighVoltages]

I will make a video about it.

[@ishdemon_]

Can you tell what is the minimum Ram I need to run the mosquito broker? Will the 1 GB pi4 be good for this?

[@HighVoltages]

Yes , it will work.

[@konradskolimowski2677]

Can i install mqtt Explorer on raspberry?

[@HighVoltages]

I am not sure if they have the Linux version, but you will find others.

[@manikshekhar7520]

why we used -y flag? what it means?

[@HighVoltages]

when you install a library , it asks you again to write y or n for whether you want to continue or not , if we put -y it automatically take yes as our answer.

[@boopeshkumarprabhakaran]

can i use Raspberry Pi Pico?

[@HighVoltages]

i have not tried but you can try and let us all know.

[@namilo8863]

how to create more MQTT user ?

[@HighVoltages]

Like we created one user , we can create multiple users. By typing "mosquitto_passwd -c passwordfile " then type password and confirm it.
