I loaded the latest OS from Raspberry Pi Imager.
I had 4 RPi's that were tv streamers no longer in service.
Two were too old to run Chromium which is all you need to display Weatherwizz. I did create a tinyurl.com for shorten the URL.
On the older two I did try different images but gave up.
One of them, I wrote a couple of bash scripts to load two tabs in chromium. Wizz on one and NOAA
https://water.weather.gov/ tide gauge on the other.
In the script I send a ctrl-tab to switch the pages displayed, --kiosk mode in chromium.
But there is an issue, that I haven't been able to figure out. The baro and wind graphs don't refresh and are blank.
If I also add a ctrl-F5 to refresh the wizz page, it displays the graphs.
This seems to be a chromium issue as switching tabs on the desktop works fine.
