This code works best with the NodeMCU V2 ESP8266 module and an 0.96" OLED display. To get you up and running in no time we created a kit that contains all the necessary parts. By buying this and other kits from us you are funding the maintenance and development of this library. Make sure you use a version of the Arduino IDE which is supported by the ESP8266 platform. If you are using the PlatformIO environment for building, choose one of the available IDE integration or the Atom-based IDE,...

...Extremely low power consumption (several weeks between charges) Idea based on David Bird's original weather display which I couldn't get to work as Weather Underground had closed down (https://github.com/G6EJD/ESP32-8266-ePaper-Weather-Display-Examples) Programming done using Arduino with the Waveshare ePaper library (https://github.com/waveshare/e-Paper/tree/master/Arduino%20UNO/epd2in13/epd2in13) and the Arduino Json library (https://github.com/bblanchon/ArduinoJson.git) Hardware: * TTGO T5 v2.13 * Li-Ion battery You will need to modify the pin settings in the Waveshare library (epdif.h) to match those that you are using. The pins for the TTGO T5 were found to be: //TTGO T5 #define RST_PIN 16 #define DC_PIN 17 #define CS_PIN 5 #define BUSY_PIN 4 #define EPD_CLK 18 #define EPD_MOSI 23

Light Weather is a free weather forecast application for mobile devices. It uses minimal internet traffic (up to 10kb per request) to retreive the weather data from the web service provided by http://www.worldweatheronline.com/.
