+# Modul: Odchozí signály (Loxone / HTTP)
+
+## Účel
+
+- EMS šle **logické signály** (např. `EXPORT_BAN_ACTIVE`) na externí cíle přes **DB konfigurované routy** (`ems.signal_route`).
+- Každý pokus o odeslání se zapisuje do **`ems.signal_outbound_journal`** (retry, HTTP metadata, stav `queued` → `sent` → `verified`).
+- **`ems.signal_state`** drží poslední požadovanou / odeslanou / ověřenou hodnotu pro **idempotenci** a diagnostiku readbacku.
+
+Kritické řízení výkonu (**Deye, EV, TČ**) zůstává ve **Modbus exporteru** a tabulce **`ems.modbus_command`**. Tento modul **nenahrazuje** plánované zápisy výkonu do invertoru ani paralelní zápis na stejné Modbus výstupy.
+
+## Hranice: signál vs. Modbus
+
+| Typ akce | Kde |
+|----------|-----|
+| Plán, ekonomika, limity výkonu, zápis registrů Deye / nabíječky / TČ | `control_exporter` + `ems.modbus_command` |
+| Indikace (LED), informativní stav do Loxone, jednoduchý HTTP přepínač (Shelly) | `ems.signal_*` + `services/signal_service.py` |
+
+Duplicitní ovládání **stejného fyzického výstupu** přes Modbus i přes signálový HTTP kanál se vyhýbe — jedna autoritativní cesta na výstup.
+
+## Destinace
+
+| `destination_type` | Chování |
+|--------------------|---------|
+| `loxone_vi` | `GET {base}/dev/sps/io/{destination_key}/{value_text}` (stejná konvence jako legacy `send_loxone_setpoints`). |
+| `http_rest` | Zápis z `route_config_json` (`method`, `path_template` s `{value}` / `{v}`). Verify přes `verify_config_json` (`read_path`, volitelně `json_path` pro JSON odpověď). |
+
+## Worker běh
+
+- Zařazení (`enqueue_site_signals`) probíhá po **každém** dokončeném pokusu o `export_setpoints` (včetně předčasných returnů u AUTO bez plánu), v `finally` bloku — aby LED mohla klesnout i při chybějícím plánu.
+- Odeslání a verify běží v **APScheduler** jobech v `backend/app/lifespan.py` (interval řádů sekund).
+
+## Konfigurace (příklad Loxone + readback)
+
+Viz [Loxone integrace – VI/VO](../loxone-integration.md) (`EMS_ExportBan_Active`, `EMS_ExportBan_Active_FB`).
