Make a low-power Wi-Fi e-paper badge with Badger 2040 W

Build the badge as a cached, occasionally refreshed display rather than a miniature always-online dashboard. Start from Badger OS examples, design a high-contrast monochrome layout, fetch only compact data, save the last good result locally, and spend most of the time asleep.
