In this part we will send the measurement data to a broker via MQTT. These can then be displayed later with io-Broker or Grafana.
In this part you will find out how to control an LCD display with the ESP32 and how to display a menu on it. In this part we will solder for the last time.
In this part we will implement the control in a state machine. I will explain to you how my heater works and we will solder again to control the pump.
In this part we will solder for the first time and read out the DS18B20 temperature sensors. We will also create the second configuration page through which we can assign the sensors to the measuring points.
In the second part, we set up a mini HTTP server through which we can configure the ESP32. We will only create one configuration page in this part, and at least two more in the further course.
In the first part of the tutorial you will learn how to install MicroPython on the ESP32 and establish a WiFi connection.
