A self-hosted iPhone monitor that tracks wine-fridge temperature through a Raspberry Pi and Zigbee sensor.

Landing page captured for the 2026-08-31 issue.

Field notes

Monitoring is split across three local components: a Zigbee sensor reports to a Raspberry Pi server, while the iPhone reads live and historical data and receives alerts. The page specifies per-fridge temperature ranges, six-hour-to-one-year history, battery and signal reporting, and alarms when a sensor goes silent. Remote access is handled through Tailscale from inside the app, with no router ports opened; listed hardware examples total roughly €75–95.
