Nextion HMI displays are great. But the documentation and the support is not very good, and the library currently does not work with the ESP32. Today I will show you the five most important features of the enhanced version and how to use them.
In the end, you will have a small keypad which can be used as a control center for your home automation. And of course, the library works now with the ESP32, not only with the Arduino.

I did already some videos about Nextion displays. They are the basis for this video and worthwhile to watch because I will not cover these details again. You will find links in the description.

Today we will:
1. Build a small device using a Nextion display with 6 Softkeys
2. When one of these keys is pressed, the beeper on the extension board will beep. You will learn how to achieve this by programming the display itself
3. Each key triggers an MQTT message. This message can be used to switch devices in your home-automation system
4. The device can receive MQTT commands and switch a relay accordingly
5. The enhanced version has a Realtime clock aboard. We will synchronize this clock once using internet NTP time. From then on, the display updates the time itself
