The Israel Sirens panel (internal id oref-sirens) surfaces the OREF (Israel Home Front Command / Pikud HaOref) civil-defence siren feed in real time. When sirens are active, the panel shows the impacted localities; when none are active, it shows 24-hour history grouped into waves so an analyst can see the recent pattern at a glance.

​
What the panel shows

Two states under a single panel frame:
  • Active siren state — current OrefAlert[] with impacted areas and threat labels.
  • History state — the last 24 hours of siren activity grouped into waves (historyWaves: OrefHistoryEntry[]). The count badge shows the total wave count in view (MAX_HISTORY_WAVES = 50).
Summary counters surface across the panel:
  • 24-hour count — number of siren waves in the last 24h.
  • Total history count — full retained waves.
  • Configured state — when the OREF relay isn’t configured, the panel renders an explicit “not configured” empty state rather than a silent zero.
A 3-minute client cache (HISTORY_TTL = 3 * 60 * 1000) and an in-flight flag (historyFetchInFlight) prevent thundering-herd re-fetches when the panel re-renders. Panel id is oref-sirens; canonical component is src/components/OrefSirensPanel.ts. Title from i18n (panels.orefSirens); config name: “Israel Sirens”.

How you reach it

  • Cmd+K: type siren or oref.
  • Availability by variant: registered and enabled by default in the full/geopolitical variant only (priority: 2). The full-variant registration layers premium: 'locked' on desktop (_desktop && { premium: 'locked' as const }), so the panel is free on web and PRO-locked on desktop. Not present in the tech, finance, commodity, or happy variants. Source: 'oref-sirens' in FULL_PANELS of src/config/panels.ts.

​
Data sources

  • fetchOrefHistory() in @/services/oref-alerts — backed by /api/oref-alerts (a Railway relay that mirrors the OREF feed; documented under Proxies).
  • Live sirens are delivered separately via the same relay; the panel’s setData() path accepts an OrefAlertsResponse with the configured flag + active alert list.

​
Refresh cadence

Real-time for active sirens. History is client-cached for 3 minutes to damp re-fetch on re-render.

​
Tier & gating

Free on web; PRO-locked on desktop. Registered without premium on the web path; the desktop variant spreads premium: 'locked' via the _desktop && clause.

API reference

  • /api/oref-alerts — relay proxy documented under Proxies.
