Got my ESP32-based e-ink weather station running!

For the sake of my finances can you please not do cool things I want to duplicate? Thanks

Looks great! Can you post links to the device? And code?

I suggest you use this one:

::: spoiler Raw bytes

This is a drop-in replacement for the array in Adafruit's glcdfont.c.
