Yes, I am very happy that everything is now working as it should.
This will now be a good starting point for me to learn MicroPython and get used to the RP2040.

Im new to all this but could you share the weather.py info, I’m trying to do the same thing and no luck.
I don’t know if @alphanumeric created their own weather.py file. Otherwise, you can check Pimoroni’s Github page for tufty2040’s examples.

This is my latest version, let me know what you think of it.
