Although these modules are shipped with the NodeMcu firmware installed, it's very easy to load your own firmware using the Arduino IDE. There are loads of websites detailing installing the ESP8266 Boards Manager (Google) and, once installed, you write code in the normal Arduino IDE and upload it directly into the ESP8266 module without using the Arduino (Uno, mega, whatever) at all. The ESP8266 *replaces* the Arduino hardware.

Sketches are written exactly as for the Arduino, the only point to note is that, in common with most ESP8266 development boards, the pin numbers written on the silk screen are NOT the numbers to use in your sketches. You need to use the actual "GPIO" pin numbers of the ESP8266 chip itself - Google ESP82266-12E pinout.

The attached photo shows the ESP8266 module being put through its paces. Measuring temperature with a DS18b20, measuring pressure and temperature with a BMP180 module and lighting two LEDS.

At the same time, the ESP8266 module is connected by WiFi to my router and I'm able to display the sensor measurements and control the two LEDS via a simple webpage created by the onboard Arduino-style sketch.

In meiner kleinen Wetterstation habe ich einen ESP8266 verbaut. Das Arduino-kompatible Modul führt die Verbindung zu meinem WLAN durch. Bisher funktioniert das ausgezeichnet. Ich werde einie weiter Experiment mit diesem preiswerten Modul machen. Mein Video mit der Arbeitsweise der Wetterstation habe ich hier: https://youtu.be/DSEfxub_-f4
