Setup

1. The first thing you need is a free API key from https://home.openweathermap.org/users/sign_up.
2. Open 'weather.py' and replace **Key Here** with your API key.
3. **Location** can be left as it is unless you want to add it to your display.
4. Get your **longitude** and **lattitude** using I used https://www.latlong.net and put that in as well.
5. Set CSV_OPTION to False if you would not like weather data appended to 'records.csv' after every refresh.
6. There is also a reminder for taking out the trash near the end of the script that you will want to change if your trash pickup doesn't come on Monday and Thursday like mine. :)

That's about it. Run the python file and you should see output on the display.

Note

If you are not using a 7.5 inch Version 2 display, you will want to replace 'epd7in5_V2.py' in the 'lib' folder with whichever one you have from https://github.com/waveshare/e-Paper/tree/master/RaspberryPi_JetsonNano/python/lib/waveshare_epd
Fairly extensive adjustments will have to be made for other sized screens.
