A demonstration of the power of MQTT in combination with Node-RED. We'll also take a look at the "universal" Tasmota firmware for ESP8266 and ESP32-based devices. This all to hopefully make you enthusiastic to start building your own projects with these building blocks.

MQTT is a very light message transport mechanism that uses a standard network connection and a subscribe-publish
protocol to get messages from one device to one or more others in the network in a structured manner.
Node-RED is a programming tool for wiring together hardware devices, APIs and online services very suited for working with MQTT messages.
Tasmota started as a universal firmware for ESP8266/8285 IoT-devices, now with added support for the ESP32 and it comes with MQTT-support out of the box.
With these tools, a raspberry pi and a few lines of script, we can start building home automation or whatever you want.
