Weather Station

First, make sure you have a valid Python 3 installation. When typing python in a terminal, it should open the Python REPL :

Python 3.7.4 (default, Jul 16 2019, 07:12:58) 
[GCC 9.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> ▯ 

Create a new folder that will contain the project, go into the new folder and create a Python virtual environment :

python -m venv env

Source the environment and install PlatformIO inside it using pip :

# On Linux and MacOS
source env/bin/activate
# On Windows
env\Scripts\activate.bat
# Install platformio
pip install platformio

Initiate a new PlatformIO project :

platformio init

This will create a few files and folders. Open platformio.ini and write the following inside :

[env:nodemcuv2]
platform = espressif8266
board = nodemcuv2
framework = arduino
lib_deps =  ESP8266 Weather Station,
            JsonStreamingParser,
            ESP8266_SSD1306,
            simpleDSTadjust

Add those 3 files into the src folder :

• WeatherStationDemo.ino
• WeatherStationFonts.h
• WeatherStationImages.h

And rename WeatherStationDemo.ino to main.cpp. Then build and upload the project by doing :

platformio run --target upload

To get data, be sure to set the following variables in main.cpp :

L49: const char* WIFI_SSID = "yourssid";
L50: const char* WIFI_PWD = "yourpassw0rd";

...

L72: String OPEN_WEATHER_MAP_APP_ID = "XXX";

...

L79: String OPEN_WEATHER_MAP_LOCATION_ID = "2657896";

...

L89: String OPEN_WEATHER_MAP_LANGUAGE = "de";

The comments above the variables should explain their meanings and how they should be filled.
