v0.3.9

Added

• Device name display (use_device_names) — new toggle in Advanced Settings. When enabled, offline/recovered sensor states show the HA device name (e.g. "Entrance Smoke Detector") instead of the entity friendly name (e.g. "Smoke Detector Density"). Applies to Offline Entities, Recently Offline, Recently Recovered, and Low Battery sensors, including their combined-group counterparts. Falls back to entity friendly name for entities not linked to an HA device (helpers, template sensors, virtual entities). Opt-in, default off — existing groups are unaffected.

Changed

• Coordinator: state-change debounce reduced from 2 s to 0.5 s. The debounce coalesces rapid same-entity event bursts before triggering a coordinator refresh; false-alarm filtering is handled separately by the cooldown setting. 0.5 s fully absorbs real protocol flap windows (Zigbee/Z-Wave/WiFi all settle within 1 s) while cutting offline-detection latency by 75 %.
