MarCas Tech has developed a small DIY weather station using a simple ESP8266 and a 1.3" OLED display. Within the code, you need to make a WiFi connection with static addressing and retrieve your city information via the API. You can retrieve this information via registration at https://openweathermap.org/.
The connection of the display to the hardware is very simple :
VDD - 3V
GND - GND
SCK - D2
SDA - D1
The library used is the 8x8lib library that you can easily find on the web.
