Keep /alive unchanged and serve a dashboard at / with status cards, latency graphs, an event timeline, and a Wi-Fi section. Background monitors on configurable intervals: TCP reachability, DNS resolution, public IP change detection, host reboot detection, Wi-Fi link quality, and Wi-Fi scan of networks in range via iw. The Wi-Fi interface is selected with WIFI_INTERFACE; the page lists visible interfaces and reports when none is available. Scan results stay in memory, other metrics go to SQLite on a mounted volume. Optional MQTT publishing with Home Assistant discovery groups all sensors under one device per host.
