I built a Raspberry Pi with an e-ink panel showing server health, backup state, camera status, and currently active users. It is genuinely pleasant: a glance gives me local, persistent status without opening a browser or depending on a remote dashboard. E-ink also suits information that does not need rapid updates, since it is readable in bright conditions and can retain its last image without power.
But the same glance is available to anyone visiting the room. “Camera offline,” named users, backup timestamps, or recurring uptime patterns could reveal routines, absences, household activity, or weaknesses. My current view is that the panel is worth keeping only if it shows coarse states—“OK” or “attention”—while names, timestamps, hostnames, IPs, and failure details stay behind authentication. Would you build one? What would you hide, and what safer alternatives or examples have you tried?
