MQTT and Home Assistant: An Abridged Version

Curious about using MQTT with Home Assistant? In this short abridged version of my other MQTT videos, I'll cover:

· What is MQTT and when might you use it?
· Setting up MQTT with Home Assistant in minutes
· Controlling devices and receiving updates with MQTT in Home Assistant
· Adding MQTT to your custom devices and projects
· Implementing MQTT Discovery for automatic creation of your entities

This is not intended as a complete "how-to" video, but more of an introduction. Each topic discussed will include a link to a seperate related video with many more details and step-by-step directions for those topics. These related videos are also linked below.

Sir, your MQTT video is very good, but I am a beginner. I can't find any simple videos on how to write Arduino code for ESP32 and how to work with Home Assistant. I tried searching on Google but still don't fully understand how to start. I think ESP32 is not good with Arduino because mostly I see videos with SP32. Can you help me with this or maybe make a video for beginners?

My basic requirement for the first step is understanding what Arduino library is needed and the basic needs for ESP32 Arduino code with WiFi settings, MQTT basic code, etc. Then, how to work with Home Assistant. Please start from the ground level, like turning LED on and off with ESP32 + Arduino + Home Assistant, Thank you !

I'm struggling with this. I'm trying to make a basic Arduino sketch to send info to HA over mqtt. At around 8:13 you have a command client.connect("Matrix", user, pass) I am not clear on what I replace Matrix with in my code. I think I have mqtt set up properly on my HA. My esp32 unit connects to my wifi but it is not able to connect to mqtt. I expect something is wrong with that connect command. A video showing a super simple Arduino sketch connecting to HA would be nice. I saw your video with the clock but the code is so bloated with the clock stuff that I found it a challenge to follow. Thank you.
