No i mean like this kinds of weather stations, which predict sun or rain or clouds, without data from the internet, only from the onboard sensors
How can you predict weather from temperature, humidity and pressure data, dht11 an bmp 280 sensor, links to websites would also be helpfull,
A forecast at approx. 09:00 local Solar Time is allegedly better than 90% accurate ! - even though it takes no account of rate of barometer change, wind speed or temperature.
