I had 2 raspberry pi's, a 7" monitor and a 21" monitor that I used do some simple python apps on. I found an app on GitHub https://github.com/genebean/PiWeatherRock for a raspberry pi weather display using an online weather source.
So loaded it on my pi with 7" monitor. 7" has current weather, 4 hour hourly forecast and 4 hour daily forecast.
And then recoded the app to work on my 21" monitor. It has current weather, 7 hour and 7 day forecasts. Put the 7" on my desk and 21" out in my workshop.
Very cool Ronstar. I also know the Python coding language so we have more in common than I thought. I havent picked up a Pi. I considered it but hard to find time to do this.
