+## Timescale continuous aggregates (střídač → dashboard)
+
+Nad `ems.telemetry_inverter` běží dva **continuous aggregate** (TimescaleDB); oba se periodicky obnovují (řádově každých 15 minut). Definice CA je ve **verzovaných** migracích (`V011`, `V039`); **view** nad CA držíme v **repeatable** souborech (`db/views/R__*.sql`), aby šla měnit jedna aktuální definice bez nové V migrace.
+
+| Objekt | Bucket | View pro PostgREST / UI | Poznámka |
+|--------|--------|-------------------------|----------|
+| `ems.telemetry_inverter_hourly` | 1 hodina | `ems.vw_telemetry_hourly_7d` | CA a view v **V011**; `security_invoker` v **V031**. Hodinové trendy. |
+| `ems.telemetry_inverter_15m` | 15 minut | `ems.vw_telemetry_15m_7d` | **`db/views/R__vw_telemetry_15m_7d.sql`** – posledních 7 dní, zarovnání s 15min sloty přehledu. |
+
+**Frontend přehled** (`frontend/src/hooks/useDashboardData.ts`): skutečné výkony a SoC po slotech bere z **`/vw_telemetry_15m_7d`** (klíč slotu = začátek 15min intervalu v UTC, stejně jako `floorSlotUtcMs` v grafu). Horní karty a **aktuální SoC** v grafu jsou dál z **`vw_site_status`** (poslední 1min vzorek) a z WebSocketu `/ws/telemetry`, aby „teď“ odpovídalo boxu i po refreshi agregátu.
+
+**Plánovač** počáteční SoC nečte z těchto view – bere poslední řádek z `ems.telemetry_inverter` (`planning_engine._load_site_context`).
