Hi, where can I download the jpeg-files referenced in line 102, 104?

        icon="greycloud.jpeg"
    else:
        icon="sunny.jpeg"

@KHome - These are custom images I've created by downloading images from the internet and resized. You will need to create your own.
On the version of the code now shown above, I use the images now called 01d.jpg and 01n.jpg for example

@KHome I have found some icons that are licenced under the creative commons licence. So I have made up a full set of them you can download from https://talktech.info/wp-content/uploads/2023/03/weather.7z

You need to unzip those and load them into the PicoW internal memory.

I have made some quality of life changes. It was not getting the time correctly unless run from thony.
Now I can get it to sync better.
Also added some "on display" debug notes so you can tell if it is connected to the Wifi or not
