This is on an reTerminal E1002 (using a Spectra 6 e-ink screen). It refreshes every 30 minutes to point to the current 30 minutes block + show the cost. Using checkerboard pattern to get more colours than the default 6 supported by the screen.

This looks pretty nice! I wonder if you could use pixel fonts to avoid the strange pattern on the lowercase 'o'.

Thanks! The current rate is already using a bitmap font, and so are the graph's labels (Neue Bit). The main title isn't (it's just Roboto), because Neue Bit bolded wasn't bolded enough. Trying to find a good mix of a good looking font that renders well when bolded that isn't too pixelly a font either
