-
-## Zugriff
-
-- **Web UI**: http://<server-ip>:8002
-- **API Docs**: http://<server-ip>:8001/docs
-- **Simulator**: http://<server-ip>:8010
-
-Auf localhost: `127.0.0.1` oder `localhost`
-
-## finch/nerdctl Besonderheiten
-
-### Port-Binding Verhalten (nur macOS/Windows)
-
-**Standard Docker auf Linux:**
-- `-p 8001:8001` → bindet auf `0.0.0.0:8001` (von überall erreichbar)
-
-**finch/nerdctl auf macOS:**
-- `-p 8001:8001` → bindet auf `127.0.0.1:8001` (nur localhost)
-- Dies ist ein **Security-Feature** von nerdctl
-- **Auf Linux-Servern ist das KEIN Problem!**
-
-### Container-to-Container Kommunikation
-
-**Linux (empfohlen):**
-```bash
-# Docker Network verwenden - Container sprechen sich mit Namen an
-docker network create home-automation
-docker run --network home-automation --name api ...
-docker run --network home-automation -e API_BASE=http://api:8001 ui ...
-```
-
-**macOS mit finch:**
-```bash
-# host.docker.internal verwenden
-docker run --add-host=host.docker.internal:host-gateway \
-  -e API_BASE=http://host.docker.internal:8001 ui ...
-```
-
-## Container verwalten
-
-```bash
-# Alle Container anzeigen
-docker ps
-
-# Logs anschauen
-docker logs api
-docker logs ui -f  # Follow mode
-
-# Container stoppen
-docker stop api ui abstraction simulator
-
-# Container entfernen
-docker rm api ui abstraction simulator
-
-# Alles neu starten
-docker stop api ui abstraction simulator && \
-docker rm api ui abstraction simulator && \
-# ... dann Quick Start Befehle von oben
-```
-
-## Troubleshooting
-
-### UI zeigt "Keine Räume oder Geräte konfiguriert"
-
-**Problem:** UI kann API nicht erreichen
-
-**Linux - Lösung:**
-```bash
-# Verwende Docker Network
-docker network create home-automation
-docker stop ui && docker rm ui
-docker run -d --name ui \
-  --network home-automation \
-  -p 8002:8002 \
-  -e API_BASE=http://api:8001 \
-  ui:dev
-```
-
-**macOS/finch - Lösung:**
-```bash
-docker stop ui && docker rm ui
-docker run -d --name ui \
-  --add-host=host.docker.internal:host-gateway \
-  -p 8002:8002 \
-  -e API_BASE=http://host.docker.internal:8001 \
-  ui:dev
-```
-
-### "Connection refused" in Logs
-
-**Check 1:** Ist die API gestartet?
-```bash
-docker ps | grep api
-curl http://127.0.0.1:8001/health
-```
-
-**Check 2:** Hat UI die richtige API_BASE?
-```bash
-docker inspect ui | grep API_BASE
-```
-
-### Port bereits belegt
-
-```bash
-# Prüfe welcher Prozess Port 8001 nutzt
-lsof -i :8001
-
-# Oder mit netstat
-netstat -an | grep 8001
-
-# Alte Container aufräumen
-docker ps -a | grep -E "api|ui|abstraction|simulator"
-docker rm -f <container-id>
-```
-
-## Produktiv-Deployment
-
-Für Produktion auf **Linux-Servern** empfohlen:
-
-1. **Docker Compose** (siehe `infra/docker-compose.yml`)
-2. **Docker Network** für Service Discovery (siehe Linux Quick Start oben)
-3. **Volume Mounts** für Persistenz
-4. **Health Checks** in Kubernetes/Compose (nicht im Dockerfile)
-
-### Beispiel mit Docker Network (Linux)
-
-```bash
-# Netzwerk erstellen
-docker network create home-automation
-
-# Services starten (alle im gleichen Netzwerk)
-docker run -d --name api --network home-automation \
-  -p 8001:8001 \
-  -v $(pwd)/config:/app/config:ro \
-  api:dev
-
-docker run -d --name ui --network home-automation \
-  -p 8002:8002 \
-  -e API_BASE=http://api:8001 \
-  ui:dev
-```
-
-**Vorteil:** Service Discovery über Container-Namen, keine `--add-host` Tricks nötig.

-# MAX! (eQ-3) Thermostat Integration
-
-## Overview
-
-This document describes the integration of MAX! (eQ-3) thermostats via Homegear into the home automation system.
-
-## Protocol Characteristics
-
-MAX! thermostats use a **simple integer-based protocol** (not JSON):
-
-- **SET messages**: Plain integer temperature value (e.g., `22`)
-- **STATE messages**: Plain integer temperature value (e.g., `22`)
-- **Topics**: Homegear MQTT format
-
-### MQTT Topics
-
-**SET Command:**
-```
-homegear/instance1/set/<peerId>/<channel>/SET_TEMPERATURE
-Payload: "22" (plain integer as string)
-```
-
-**STATE Update:**
-```
-homegear/instance1/plain/<peerId>/<channel>/SET_TEMPERATURE
-Payload: "22" (plain integer as string)
-```
-
-## Transformation Layer
-
-The abstraction layer provides automatic transformation between the abstract home protocol and MAX! format.
-
-### Abstract → MAX! (SET)
-
-**Input (Abstract):**
-```json
-{
-  "mode": "heat",
-  "target": 22.5
-}
-```
-
-**Output (MAX!):**
-```
-22
-```
-
-**Transformation Rules:**
-- Extract `target` temperature
-- Convert float → integer (round to nearest)
-- Return as plain string (no JSON)
-- Ignore `mode` field (MAX! always in heating mode)
-
-### MAX! → Abstract (STATE)
-
-**Input (MAX!):**
-```
-22
-```
-
-**Output (Abstract):**
-```json
-{
-  "target": 22.0,
-  "mode": "heat"
-}
-```
-
-**Transformation Rules:**
-- Parse plain string/integer value
-- Convert to float
-- Add default `mode: "heat"` (MAX! always heating)
-- Wrap in abstract payload structure
-
-## Device Configuration
-
-### Example devices.yaml Entry
-
-```yaml
-- device_id: "thermostat_wolfgang"
-  type: "thermostat"
-  cap_version: "thermostat@1.0.0"
-  technology: "max"
-  features:
-    mode: true
-    target: true
-    current: false  # SET_TEMPERATURE doesn't report current temp
-  topics:
-    set: "homegear/instance1/set/39/1/SET_TEMPERATURE"
-    state: "homegear/instance1/plain/39/1/SET_TEMPERATURE"
-  metadata:
-    friendly_name: "Thermostat Wolfgang"
-    location: "Arbeitszimmer Wolfgang"
-    vendor: "eQ-3"
-    model: "MAX! Thermostat"
-    peer_id: "39"
-    channel: "1"
-```
-
-### Configuration Notes
-
-1. **technology**: Must be set to `"max"` to activate MAX! transformations
-2. **topics.set**: Use Homegear's `/set/` path with `/SET_TEMPERATURE` parameter
-3. **topics.state**: Use Homegear's `/plain/` path with `/SET_TEMPERATURE` parameter
-4. **features.current**: Set to `false` - SET_TEMPERATURE topic doesn't provide current temperature
-5. **metadata**: Include `peer_id` and `channel` for reference
-
-## Temperature Rounding
-
-MAX! only supports **integer temperatures**. The system uses standard rounding:
-
-| Abstract Input | MAX! Output |
-|----------------|-------------|
-| 20.4°C         | 20          |
-| 20.5°C         | 20          |
-| 20.6°C         | 21          |
-| 21.5°C         | 22          |
-| 22.5°C         | 22          |
-
-Python's `round()` function uses "banker's rounding" (round half to even).
-
-## Limitations
-
-1. **No current temperature**: SET_TEMPERATURE topic only reports target, not actual temperature
-2. **No mode control**: MAX! thermostats are always in heating mode
-3. **Integer only**: Temperature precision limited to 1°C steps
-4. **No battery status**: Not available via SET_TEMPERATURE topic
-5. **No window detection**: Not available via SET_TEMPERATURE topic
-
-## Testing
-
-Test the transformation functions:
-
-```bash
-poetry run python /tmp/test_max_transform.py
-```
-
-Expected output:
-```
-✅ PASS: Float 22.5 -> Integer string
-✅ PASS: Integer string -> Abstract dict
-✅ PASS: Integer -> Abstract dict
-✅ PASS: Rounding works correctly
-🎉 All MAX! transformation tests passed!
-```
-
-## Implementation Details
-
-### Files Modified
-
-1. **apps/abstraction/transformation.py**
-   - Added `_transform_thermostat_max_to_vendor()` - converts abstract → plain integer
-   - Added `_transform_thermostat_max_to_abstract()` - converts plain integer → abstract
-   - Registered handlers in `TRANSFORM_HANDLERS` registry
-
-2. **apps/abstraction/main.py**
-   - Modified `handle_abstract_set()` to send plain string for MAX! devices (not JSON)
-   - Modified message processing to handle plain text payloads from MAX! STATE topics
-
-### Transformation Functions
-
-```python
-def _transform_thermostat_max_to_vendor(payload: dict[str, Any]) -> str:
-    """Convert {"target": 22.5} → "22" """
-    target_temp = payload.get("target", 21.0)
-    return str(int(round(target_temp)))
-
-def _transform_thermostat_max_to_abstract(payload: str | int | float) -> dict[str, Any]:
-    """Convert "22" → {"target": 22.0, "mode": "heat"} """
-    target_temp = float(payload)
-    return {"target": target_temp, "mode": "heat"}
-```
-
-## Usage Example
-
-### Setting Temperature via API
-
-```bash
-curl -X POST http://localhost:8001/devices/thermostat_wolfgang/set \
-  -H "Content-Type: application/json" \
-  -d '{
-    "type": "thermostat",
-    "payload": {
-      "mode": "heat",
-      "target": 22.5
-    }
-  }'
-```
-
-**Flow:**
-1. API receives abstract payload: `{"mode": "heat", "target": 22.5}`
-2. Abstraction transforms to MAX!: `"22"`
-3. Publishes to: `homegear/instance1/set/39/1/SET_TEMPERATURE` with payload `22`
-
-### Receiving State Updates
-
-**Homegear publishes:**
-```
-Topic: homegear/instance1/plain/39/1/SET_TEMPERATURE
-Payload: 22
-```
-
-**Flow:**
-1. Abstraction receives plain text: `"22"`
-2. Transforms to abstract: `{"target": 22.0, "mode": "heat"}`
-3. Publishes to: `home/thermostat/thermostat_wolfgang/state`
-4. Publishes to Redis: `ui:updates` channel for real-time UI updates
-
-## Future Enhancements
-
-Potential improvements for better MAX! integration:
-
-1. **Current Temperature**: Subscribe to separate Homegear topic for actual temperature
-2. **Battery Status**: Subscribe to LOWBAT or battery level topics
-3. **Valve Position**: Monitor actual valve opening percentage
-4. **Window Detection**: Subscribe to window open detection status
-5. **Mode Control**: Support comfort/eco temperature presets

-## Status: ✅ COMPLETE & TESTED
-
-All acceptance criteria have been implemented and verified.
-
----
-
-## Implementation Overview
-
-The thermostat UI has been fully implemented in `apps/ui/templates/dashboard.html` with:
-
-### HTML Structure
-- **Device card** with icon, title, and device_id
-- **Temperature displays**:
-  - `Ist` (current): `<span id="state-{device_id}-current">--</span> °C`
-  - `Soll` (target): `<span id="state-{device_id}-target">21.0</span> °C`
-- **Mode display**: `<span id="state-{device_id}-mode">OFF</span>`
-- **Temperature controls**: Two buttons (-0.5°C, +0.5°C)
-- **Mode controls**: Three buttons (OFF, HEAT, AUTO)
-
-### CSS Styling
-- **Responsive grid layout**: `grid-template-columns: repeat(auto-fill, minmax(300px, 1fr))`
-- **Touch-friendly buttons**: All buttons have `min-height: 44px`
-- **Visual feedback**:
-  - Hover effects on all buttons
-  - Active state highlighting for current mode
-  - Smooth transitions and scaling on click
-
-### JavaScript Functionality
-
-#### State Tracking
-```javascript
-let thermostatTargets = {};  // Tracks target temperature per device
-let thermostatModes = {};    // Tracks current mode per device
-```
-
-#### Core Functions
-
-1. **`adjustTarget(deviceId, delta)`**
-   - Adjusts target temperature by ±0.5°C
-   - Clamps value between 5.0°C and 30.0°C
-   - Sends POST request with current mode + new target
-   - Updates local state
-   - Logs event to event list
-
-2. **`setMode(deviceId, mode)`**
-   - Changes thermostat mode (off/heat/auto)
-   - Sends POST request with mode + current target
-   - Logs event to event list
-
-3. **`updateThermostatUI(deviceId, current, target, mode)`**
-   - Updates all three display spans
-   - Updates mode button active states
-   - Syncs local state variables
-   - Called automatically when SSE events arrive
-
-#### SSE Integration
-- Connects to `/realtime` endpoint
-- Listens for `message` events
-- Automatically updates UI when thermostat state changes
-- Handles reconnection on errors
-- No page reload required
-
----
-

-# UI API Configuration
-
-## Übersicht
-Die UI-Anwendung verwendet keine hart codierten API-URLs mehr. Stattdessen wird die API-Basis-URL über die Umgebungsvariable `API_BASE` konfiguriert.
-
-## Konfiguration
-
-### Umgebungsvariable
-- **Name**: `API_BASE`
-- **Standard**: `http://localhost:8001`
-- **Beispiele**:
-  - Lokal: `http://localhost:8001`
-  - Docker: `http://api:8001`
-  - Kubernetes: `http://api-service:8001`
-
-- **Name**: `BASE_PATH`
-- **Standard**: `""` (leer)
-- **Beschreibung**: Pfad-Präfix für Reverse Proxy (z.B. `/ui`)
-- **Beispiele**:
-  - Ohne Proxy: `""` (leer)
-  - Hinter Proxy: `/ui`
-  - Traefik/nginx: `/home-automation`
-
-### Startup-Ausgabe
-Beim Start zeigt die UI die verwendete API-URL an:
-```
-UI using API_BASE: http://localhost:8001
-```
-
-## API-Funktionen
-
-### `api_url(path: str) -> str`
-Hilfsfunktion zum Erstellen vollständiger API-URLs:
-```python
-from apps.ui.main import api_url
-
-# Beispiel
-url = api_url("/devices")  # → "http://localhost:8001/devices"
-```
-
-### Health Endpoint
-Für Kubernetes Liveness/Readiness Probes:
-```bash
-GET /health
-```
-
-Antwort:
-```json
-{
-  "status": "ok",
-  "service": "ui",
-  "api_base": "http://localhost:8001"
-}
-```
-

+# HomeKit Bridge
+
+HomeKit Accessory Protocol (HAP) Bridge für das Home Automation System.
+
+## Überblick
+
+Diese HomeKit-Bridge ermöglicht die Steuerung aller Geräte über Apple HomeKit / Home-App auf iPhone/iPad/Mac.
+
+**Architektur:**
+- Läuft auf Raspberry Pi im lokalen Netzwerk
+- Kommuniziert ausschließlich über REST-API (kein direkter MQTT/Redis-Zugriff)
+- Verwendet [HAP-Python](https://github.com/ikalchev/HAP-python) für HomeKit-Protokoll
+- Unterstützt Echtzeit-Updates über Server-Sent Events (SSE)
+
+## Implementierungsanleitung für Copilot
+
+<details>
+<summary>Copilot-Aufgabe: Implementiere die HomeKit-Bridge (HAP-Python) für unser System</summary>
+
+### Kontext
+
+- Wir verwenden HAP-Python als HomeKit-Bridge.
+- Die Bridge läuft auf einem Raspberry Pi im gleichen LAN wie die iPhones.
+- Die Bridge kommuniziert AUSSCHLIESSLICH über die REST-API mit dem restlichen System (KEIN direkter MQTT-/Redis-Zugriff).
+- Geräte- und Raum-Infos kommen aus:
+    - `GET /devices`
+    - `GET /layout`
+  und werden über `device_id` gejoint.
+- Die Abbildung von abstrakten Gerätetypen/Features auf HomeKit-Services/Characteristics steht in der Datei `apps/homekit/homekit_mapping.md` (Markdown-Tabelle). Bitte orientiere dich daran.
+
+### Ziel
+
+Implementiere eine lauffähige HomeKit-Bridge in `apps/homekit`, die:
+- beim Start Geräte & Räume über die API lädt,
+- daraus anhand der Mapping-Tabelle HomeKit-Accessories erzeugt,
+- Zustandsänderungen über einen Realtime-Endpoint der API empfängt und in HomeKit spiegeln kann,
+- Set-Kommandos aus HomeKit (z.B. Licht an/aus, Helligkeit, Zieltemperatur) per `POST /devices/{id}/set` an die API sendet,
+- saubere Start-/Stop-Logs ausgibt,
+- einfache Test-/Startanweisungen für den Raspberry Pi und die Home-App (iPhone) in Kommentaren dokumentiert.
+
+### WICHTIG
+
+- Bitte benutze HAP-Python (pyhap).
+- Keine direkte MQTT- oder Redis-Kommunikation in der Bridge.
+- Nutze HTTP(S) zur API (z.B. mit requests oder httpx; gerne sync, HAP-Python ist selbst eventloop-orientiert).
+- Nutze die Mapping-Tabelle in `apps/homekit/homekit_mapping.md` als Leitlinie für die Accessory-Typen.
+

+└── tests/                   # rudimentäre Tests/Checks
+```
+
+## Teil 1: Internes Gerätemodell / Device-Registry
+
+### 1.1 Erstelle in `apps/homekit/device_registry.py`:
+
+**Dataklasse/Model Device:**
+- `device_id: str`
+- `type: str` - "light","thermostat","outlet","contact","temp_humidity","cover",...
+- `name: str` - Kurzname aus `GET /devices.name`
+- `friendly_name: str` - title aus `GET /layout` (fallback name)
+- `room: str | None` - Raumname aus layout
+- `features: dict[str, bool]`
+- `read_only: bool` - heuristisch: Sensor-/Kontakt-Typen sind read_only
+
+**Klasse DeviceRegistry mit Funktionen:**
+- `def load_from_api(api: ApiClient) -> DeviceRegistry`:
+    - ruft `GET /devices` und `GET /layout` auf,
+    - joint über `device_id`,
+    - erstellt Device-Instanzen.
+- `get_all(): list[Device]`
+- `get_by_id(device_id: str) -> Device | None`
+
+**Akzeptanz:**
+- `load_from_api` funktioniert mit der bestehenden Struktur von `/devices` und `/layout`:
+    - `/devices` liefert mindestens `{device_id, type, name, features}`
+    - `/layout` liefert eine Struktur, aus der `device_id → room + title` ableitbar ist
+- Der Join über `device_id` klappt; fehlende Layout-Einträge werden toleriert
+
+## Teil 2: API-Client
+
+### 2.1 Erstelle in `apps/homekit/api_client.py`:
+
+**Klasse ApiClient mit:**
+- `__init__(self, base_url: str, token: str | None = None, timeout: int = 5)`
+- **Methoden:**
+    - `get_devices() -> list[dict]`: GET /devices
+    - `get_layout() -> dict`: GET /layout
+    - `get_device_state(device_id: str) -> dict`: GET /devices/{id}/state
+    - `post_device_set(device_id: str, type: str, payload: dict) -> None`: POST /devices/{id}/set
+    - `stream_realtime() -> Iterator[dict]`:
+        - GET /realtime als SSE, yield jedes Event als dict:
+          `{"type":"state","device_id":...,"payload":{...},"ts":...}`
+
+**Auth:**
+- Wenn ein API-Token via ENV `HOMEKIT_API_TOKEN` gesetzt ist, nutze HTTP-Header:
+  `Authorization: Bearer <token>`
+
+**Akzeptanz:**
+- ApiClient ist robust:
+    - bei Netzwerkfehlern gibt es sinnvolle Exceptions/Logs,
+    - `stream_realtime` behandelt Reconnect (z.B. einfache Endlosschleife mit Backoff).
+- Es werden keine MQTT-Details verwendet, nur HTTP.
+
+## Teil 3: HomeKit-Accessory-Klassen (HAP-Python)
+
+### 3.1 Erstelle in `apps/homekit/accessories/base.py`:
+
+**Basisklasse BaseDeviceAccessory(Accessory) mit:**
+- Referenz auf Device (aus DeviceRegistry)
+- Referenz auf ApiClient
+- Methoden zum:
+    - Registrieren von HAP-Characteristics und Set-Handlern
+    - Aktualisieren von Characteristics bei eingehenden Events
+- Logging
+
+### 3.2 Erstelle spezifische Accessory-Klassen basierend auf homekit_mapping.md:
+
+**LightAccessories (`apps/homekit/accessories/light.py`):**
+- On/Off (nur power)
+- Dimmable (power + brightness)
+- Color (power + brightness + color_hsb)
+
+**ThermostatAccessory:**
+- CurrentTemperature, TargetTemperature, Mode (so weit in Mapping definiert)
+
+**ContactAccessory:**
+- ContactSensorState (open/closed)
+
+**TempHumidityAccessory:**
+- TemperatureSensor (CurrentTemperature)
+- HumiditySensor (CurrentRelativeHumidity)
+
+**OutletAccessory:**
+- On/Off
+
+**CoverAccessory (optional):**
+- WindowCovering mit CurrentPosition/TargetPosition
+
+**Die Mapping-Tabelle in `homekit_mapping.md` ist die normative Referenz:**
+- Bitte lies die Tabelle und mappe `abstract_type + Features → passende Accessory-Klasse und Characteristics`
+- Wo die Tabelle `Status=TODO/REVIEW` hat:
+    - Implementiere nur das, was eindeutig ist,
+    - lasse TODO-Kommentare an den entsprechenden Stellen im Code.
+
+**Akzeptanz:**
+- Für die abstrakten Typen, die bereits in `devices.yaml` und Mapping-Tabelle klar definiert sind (z.B. light, thermostat, contact, temp_humidity), existieren passende Accessory-Klassen.
+- Set-Operationen erzeugen korrekte Payloads für `POST /devices/{id}/set`:
+    - Light: `{"type":"light","payload":{"power":"on"/"off", "brightness":..., "hue":..., "sat":...}}`
+    - Thermostat: `{"type":"thermostat","payload":{"target":...}}`
+    - Contact: read_only → keine Set-Handler
+    - Temp/Humidity: read_only → keine Set-Handler
+
+## Teil 4: Bridge-Setup mit HAP-Python
+
+### 4.1 Implementiere in `apps/homekit/main.py`:
+
+**env-Konfiguration:**
+- `HOMEKIT_NAME` (default: "Home Automation Bridge")
+- `HOMEKIT_PIN` (z.B. "031-45-154")
+- `HOMEKIT_PORT` (default 51826)
+- `API_BASE` (z.B. "http://api:8001" oder extern)
+- `HOMEKIT_API_TOKEN` (optional)
+
+**Funktion `build_bridge(driver, api_client: ApiClient) -> Bridge`:**
+- DeviceRegistry via `load_from_api(api_client)` laden.
+- Für jedes Device anhand Mapping-Tabelle die passende Accessory-Klasse instanziieren.
+- Einen Bridge-Accessory (`pyhap.accessory.Bridge`) erstellen.
+- Alle Device-Accessories der Bridge hinzufügen.
+
+**Realtime-Event-Loop:**
+- In einem Hintergrund-Thread oder ThreadPool:
+    - `api_client.stream_realtime()` iterieren,
+    - für jedes Event `device_id → Accessory` finden,
+    - Characteristics updaten.
+- Thread wird beim Shutdown sauber beendet.
+
+**`main()`:**
+- Logging einrichten.
+- ApiClient erstellen.
+- `AccessoryDriver(port=HOMEKIT_PORT, persist_file="homekit.state")` erstellen.
+- Bridge via `build_bridge(driver, api_client)` bauen.
+- Bridge dem Driver hinzufügen.
+- Realtime-Thread starten.
+- `driver.start()` aufrufen.
+- Auf KeyboardInterrupt reagieren und sauber stoppen.
+
+**Akzeptanz:**
+- Beim Start loggt die Bridge:
+    - Anzahl Devices,
+    - auf welchem Port sie als HomeKit-Bridge lauscht,
+    - welches API_BASE verwendet wird.
+- Die Datei `homekit.state` wird im Arbeitsverzeichnis bzw. einem konfigurierbaren Ordner abgelegt (um Pairing-Info persistent zu halten).
+- Die Bridge übersteht API-Neustarts (Realtime-Loop reconnectet) und Netzwerkflaps.
+
+## Teil 5: Tests & Testanweisungen
+
+### 5.1 Lege in `apps/homekit/tests/` einfache Tests/Checks an:
+
+**Unit-Tests (pytest), soweit ohne echtes HomeKit möglich:**
+- Test für `DeviceRegistry.load_from_api()` mit Mock-Antworten aus `/devices` und `/layout`:
+    - Korrekte Join-Logik,
+    - Korrekte room/friendly_name-Zuordnung.
+- Test für set-Payload-Erzeugung pro Accessory:
+    - z.B. LightAccessory: On=True → POST /devices/{id}/set wird mit korrektem Payload aufgerufen (über Mock ApiClient).
+
+### Allgemein
+
+- Nutze möglichst sinnvolle Typannotationen und Docstrings.
+- Hinterlasse TODO-Kommentare an Stellen, wo die Mapping-Tabelle explizit Status=TODO/REVIEW hat.
+- Ändere KEINE bestehenden API-Endpunkte; verlasse dich nur auf deren aktuelles Verhalten (GET /devices, GET /layout, /realtime, POST /devices/{id}/set).
+
+
+## Installation & Setup
+
+### Voraussetzungen
+
+- Python 3.9+
+- Raspberry Pi im gleichen LAN wie iPhone/iPad
+- API-Server erreichbar (z.B. `http://api:8001`)
+

+
+## Pairing mit iPhone (Home-App)
+
+1. **Voraussetzungen:**
+   - iPhone im gleichen WLAN wie Raspberry Pi
+   - Bridge läuft und zeigt "started on port 51826"
+
+2. **Home-App öffnen:**
+   - Öffne die Home-App auf dem iPhone
+   - Tippe auf "+"  → "Gerät hinzufügen"
+   - Wähle "Weitere Optionen..." oder "Code fehlt oder kann nicht gescannt werden"
+
+3. **Bridge auswählen:**
+   - Die Bridge sollte in der Nähe-Liste erscheinen (z.B. "Home Automation Bridge")
+   - Tippe auf die Bridge
+
+4. **PIN eingeben:**
+   - Gib den PIN ein: `031-45-154` (oder dein `HOMEKIT_PIN`)
+   - Format: `XXX-XX-XXX`
+
+5. **Konfiguration abschließen:**
+   - Geräte werden geladen
+   - Räume werden automatisch aus `layout.yaml` übernommen
+   - Geräte können nun über Home-App gesteuert werden
+
+## Funktionstests
+
+### Test 1: Licht einschalten
+
+**Aktion:** Lampe in Home-App antippen (On)
+
+**Erwartung:**
+- API-Log zeigt: `POST /devices/{id}/set` mit `{"type":"light","payload":{"power":"on"}}`
+- Physische Lampe oder Simulator schaltet ein
+
+### Test 2: Helligkeit ändern (dimmbare Lampe)
+
+**Aktion:** Helligkeits-Slider bewegen (z.B. 75%)
+
+**Erwartung:**
+- `POST /devices/{id}/set` mit `brightness` ca. 75
+- Lampe dimmt entsprechend
+
+### Test 3: Farbe ändern (Farblampe)
+
+**Aktion:** Farbe in Home-App wählen
+
+**Erwartung:**
+- `POST /devices/{id}/set` mit `hue`/`sat` Werten
+- Lampe wechselt Farbe
+
+### Test 4: Thermostat Zieltemperatur
+
+**Aktion:** Zieltemperatur auf 22°C setzen
+
+**Erwartung:**
+- `POST /devices/{id}/set` mit `target=22`
+- `CurrentTemperature` wird über `/realtime` aktualisiert
+
+### Test 5: Kontaktsensor (read-only)
+
+**Aktion:** Fenster physisch öffnen/schließen
+
+**Erwartung:**
+- `/realtime` sendet Event
+- Home-App zeigt "Offen" oder "Geschlossen"
+
+### Test 6: Temperatur-/Feuchtigkeitssensor
+
+**Aktion:** Werte ändern sich (z.B. Heizung an)
+
+**Erwartung:**
+- `/realtime` Events aktualisieren Werte
+- Home-App zeigt aktuelle Temperatur/Luftfeuchtigkeit
+
+## Troubleshooting
+
+### Bridge erscheint nicht in Home-App
+
+- **Netzwerk prüfen:** iPhone und RPi im gleichen Subnet?
+- **Firewall prüfen:** Port 51826 muss erreichbar sein
+- **Logs prüfen:** Fehler beim Start?
+- **mDNS/Bonjour:** Funktioniert Bonjour im Netzwerk?
+
+### Geräte reagieren nicht
+
+- **API-Logs prüfen:** Kommen POST-Requests an?
+- **Realtime-Verbindung:** Läuft `/realtime` Event-Loop? (Log-Meldungen)
+- **API-Endpoints testen:** Manuell mit `curl` testen
+
+### Pairing schlägt fehl
+
+- **State-Datei löschen:** `rm homekit.state` und Bridge neu starten
+- **PIN-Format prüfen:** Muss `XXX-XX-XXX` Format haben
+- **Alte Pairings löschen:** In Home-App unter "Home-Einstellungen" → "HomeKit-Geräte zurücksetzen"
+
+### Realtime-Updates funktionieren nicht
+
+- **SSE-Verbindung prüfen:** Logs zeigen "Starting realtime event loop..."?
+- **API-Endpoint testen:** `curl -N http://api:8001/realtime`
+- **Firewall/Proxy:** Blockiert etwas SSE-Streams?
+
+## Docker Deployment
+
+### Dockerfile
+
+```dockerfile
+FROM python:3.11-slim
+
+WORKDIR /app
+
+COPY requirements.txt .
+RUN pip install --no-cache-dir -r requirements.txt
+
+COPY . .
+
+CMD ["python", "-m", "apps.homekit.main"]
+```
+
+### docker-compose.yml
+
+```yaml
+services:
+  homekit:
+    build: ./apps/homekit
+    environment:
+      - API_BASE=http://api:8001
+      - HOMEKIT_PIN=031-45-154
+      - HOMEKIT_NAME=Home Automation Bridge
+    ports:
+      - "51826:51826"
+    volumes:
+      - ./data/homekit:/data
+    network_mode: "host"  # Wichtig für mDNS/Bonjour Discovery
+    restart: unless-stopped
+```
+
+**Wichtig:** `network_mode: "host"` ist erforderlich für mDNS/Bonjour Discovery, damit die Bridge im lokalen Netzwerk gefunden werden kann.

+Copilot-Aufgabe: HomeKit-Accessory-Mapping-Tabelle aus bestehender Implementierung ableiten
+
+Ziel:
+Erstelle eine Mapping-Tabelle, die beschreibt, wie unsere abstrakten Gerätetypen
+(type/Features aus devices.yaml, apps/abstraction und apps/api) auf HomeKit-Accessories
+und Characteristics (HAP-Python) abgebildet werden sollen.
+
+Die Tabelle soll:
+- sich an der bestehenden Implementierung und Konfiguration orientieren:
+  - devices.yaml (Typen, Features)
+  - apps/abstraction (Capabilities, Payload-Strukturen, Topics)
+  - apps/api (DTOs, /devices-Response, /devices/{id}/set, /realtime-Events)
+- für jeden bekannten Gerätetyp (z.B. light, thermostat, outlet, contact, temp_humidity, cover, switch)
+  festhalten:
+  - Abstract Type (type)
+  - Relevante Features (Features-Flags, z.B. power, brightness, color_hsb, target, current, contact, humidity)
+  - HomeKit Service (z.B. LightBulb, Thermostat, Outlet, ContactSensor, TemperatureSensor, HumiditySensor, WindowCovering)
+  - HomeKit Characteristics (z.B. On, Brightness, Hue, Saturation, CurrentTemperature, TargetTemperature, ContactSensorState, CurrentPosition, TargetPosition)
+  - State-Mapping (abstraktes payload → HomeKit-Characteristics)
+  - Set-Mapping (HomeKit-Characteristics → HTTP POST /devices/{id}/set Payload)
+  - Status (OK / REVIEW / TODO)
+
+Vorgehen für Copilot:
+1. Analysiere die bestehenden Typen und Features:
+   - devices.yaml → "type" und "features" pro Gerät
+   - apps/abstraction → Capabilities, State-/Set-Modelle (z.B. light@1.2.0, thermostat, contact, temp_humidity)
+   - apps/api:
+       - Response-Modell von GET /devices (device_id, type, name, features)
+       - Struktur von GET /devices/{id}/state (payload-Felder je Typ)
+       - Struktur der Events in /realtime (payload-Felder je Typ)
+       - Body von POST /devices/{id}/set (type, payload)
+
+2. Lege aufgrund dieser Analyse alle aktuell verwendeten abstrakten Typen an, z.B.:
+   - light (mit power, brightness, color_hsb)
+   - thermostat (mit current, target, mode)
+   - outlet
+   - contact
+   - temp_humidity
+   - ggf. cover, switch, etc., falls vorhanden
+
+3. Erstelle eine Tabelle in Markdown mit folgenden Spalten:
+
+   | Abstract Type | Features (aus devices.yaml) | HomeKit Service | HomeKit Characteristics | State-Mapping (payload → HK) | Set-Mapping (HK → payload) | Status |
+   |---------------|-----------------------------|-----------------|-------------------------|------------------------------|----------------------------|--------|
+
+   Beispiele für Inhalte:
+   - Abstract Type: `light`
+   - Features: `power, brightness, color_hsb`
+   - HomeKit Service: `LightBulb`
+   - HomeKit Characteristics: `On, Brightness, Hue, Saturation`
+   - State-Mapping: `payload.power -> On; payload.brightness -> Brightness; payload.hue -> Hue; payload.sat -> Saturation`
+   - Set-Mapping: `On -> {"type":"light","payload":{"power":"on"/"off"}} ...`
+   - Status: `OK` wenn Mapping klar, `REVIEW` wenn du unsicher bist, `TODO` wenn Informationen fehlen
+
+4. Nutze vorhandene Informationen aus dem Code:
+   - Wenn ein Gerätetyp in apps/abstraction bereits ein klares State-/Set-Modell hat, übernimm das in State-/Set-Mapping.
+   - Wenn bestimmte Features noch nicht im Code genutzt werden, markiere die entsprechenden Mapping-Zeilen mit Status=TODO.
+   - Falls unklar ist, welcher HomeKit-Service für einen Typ am besten passt, mache einen Vorschlag und setze Status=REVIEW.
+
+5. Markiere explizit, wo man später noch eingreifen muss:
+   - In der Spalte "Status" mit `REVIEW` oder `TODO`.
+   - Optional zusätzliche kurze Kommentare unter der Tabelle wie:
+     - `<!-- TODO: RGBW-Unterstützung prüfen -->`
+     - `<!-- REVIEW: Soll temp_humidity als zwei Accessories oder kombiniert abgebildet werden? -->`
+
+Akzeptanz-Kriterien:
+- Es existiert am Ende dieses Dokuments eine Markdown-Tabelle mit mindestens allen abstrakten Gerätetypen, die aktuell in devices.yaml / apps/abstraction / apps/api verwendet werden.
+- Für jeden Typ sind HomeKit Service und Characteristics ausgefüllt oder mit Status=REVIEW/TODO markiert.
+- State-/Set-Mapping ist für alle bereits gut verstandenen Typen (z.B. einfache Lichter, Thermostate, Kontakte, Temp/Humidity-Sensoren) konkret beschrieben.
+- Stellen, an denen die aktuelle Implementierung keine klaren Informationen liefert, sind sichtbar mit Status=REVIEW oder TODO gekennzeichnet.
+- Copilot ändert an keiner anderen Stelle des Codes etwas, sondern erzeugt nur diese Tabelle/Dokumentation.

+## Offene Punkte und Kommentare
+
+<!-- OK: thermostat - Verwendet nur Mode "auto" (TargetHeatingCoolingState=3, CurrentHeatingCoolingState=1). Keine Mode-Änderung über HomeKit möglich. -->
+
+<!-- REVIEW: temp_humidity - Soll als ein kombiniertes Accessory oder zwei separate Accessories (TemperatureSensor + HumiditySensor) abgebildet werden? HAP-Python erlaubt beides -->
+
+<!-- TODO: cover - Position/Tilt-Mapping validieren. Sind die Wertebereiche korrekt? Gibt es zusätzliche Features wie PositionState (opening/closing/stopped)? -->
+
+<!-- TODO: RGBW-Unterstützung - Prüfen, ob separate ColorTemperature-Characteristic für Warmweiß/Kaltweiß benötigt wird -->
+
+<!-- TODO: Prüfen, ob weitere Gerätetypen in devices.yaml existieren (z.B. motion, door, lock, fan, etc.) und diese ergänzen -->
+
+## Hinweise zur Implementierung
+
+- **State-Updates**: Alle State-Änderungen von MQTT/API werden auf entsprechende HomeKit-Characteristics gemappt und via `set_value()` aktualisiert
+- **Set-Befehle**: HomeKit-Charakteristik-Änderungen werden in HTTP POST-Requests an `/devices/{id}/set` umgewandelt
+- **Read-only Sensors**: Sensoren (contact, temp_humidity) unterstützen nur State-Updates, keine Set-Befehle
+- **Bidirektionales Mapping**: Änderungen müssen in beide Richtungen synchronisiert werden (HomeKit ↔ Abstraction Layer)

-# Rule Interface Documentation
-
-## Overview
-
-The rule interface provides a clean abstraction for implementing automation rules. Rules respond to device state changes and can publish commands, persist state, and log diagnostics.
-
-## Core Components
-
-### 1. RuleDescriptor
-
-Configuration data for a rule instance (loaded from `rules.yaml`):
-
-```python
-RuleDescriptor(
-    id="window_setback_wohnzimmer",           # Unique rule ID
-    name="Fensterabsenkung Wohnzimmer",       # Optional display name
-    type="window_setback@1.0",                # Rule type + version
-    targets={                                  # Rule-specific targets
-        "rooms": ["Wohnzimmer"],
-        "contacts": ["kontakt_wohnzimmer_..."],
-        "thermostats": ["thermostat_wohnzimmer"]
-    },
-    params={                                   # Rule-specific parameters
-        "eco_target": 16.0,
-        "open_min_secs": 20
-    }
-)
-```
-
-### 2. RedisState
-
-Async state persistence with automatic reconnection and retry logic:
-
-```python
-# Initialize (done by rule engine)
-redis_state = RedisState("redis://172.23.1.116:6379/8")
-
-# Simple key-value with TTL
-await ctx.redis.set("rules:my_rule:temp", "22.5", ttl_secs=3600)
-value = await ctx.redis.get("rules:my_rule:temp")  # Returns "22.5" or None
-
-# Hash storage (for multiple related values)
-await ctx.redis.hset("rules:my_rule:sensors", "bedroom", "open")
-await ctx.redis.hset("rules:my_rule:sensors", "kitchen", "closed")
-value = await ctx.redis.hget("rules:my_rule:sensors", "bedroom")  # "open"
-
-# TTL management
-await ctx.redis.expire("rules:my_rule:temp", 7200)  # Extend to 2 hours
-
-# JSON helpers (for complex data)
-import json
-data = {"temp": 22.5, "humidity": 45}
-await ctx.redis.set("rules:my_rule:data", ctx.redis._dumps(data))
-stored = await ctx.redis.get("rules:my_rule:data")
-parsed = ctx.redis._loads(stored) if stored else None
-```
-
-**Key Conventions:**
-- Use prefix `rules:{rule_id}:` for all keys
-- Example: `rules:window_setback_wohnzimmer:thermo:device_123:previous`
-- TTL recommended for temporary state (previous temperatures, timers)
-
-**Robustness Features:**
-- Automatic retry with exponential backoff (default: 3 retries)
-- Connection pooling (max 10 connections)
-- Automatic reconnection on Redis restart
-- Health checks every 30 seconds
-- All operations wait and retry, no exceptions on temporary outages
-
-### 3. MQTTClient
-
-Async MQTT client with event normalization and command publishing:
-
-```python
-# Initialize (done by rule engine)
-mqtt_client = MQTTClient(
-    broker="172.16.2.16",
-    port=1883,
-    client_id="rule_engine"
-)
-
-# Subscribe and receive normalized events
-async for event in mqtt_client.connect():
-    # Event structure:
-    # {
-    #     "topic": "home/contact/sensor_1/state",
-    #     "type": "state",
-    #     "cap": "contact",           # Capability (contact, thermostat, etc.)
-    #     "device_id": "sensor_1",
-    #     "payload": {"contact": "open"},
-    #     "ts": "2025-11-11T10:30:45.123456"
-    # }
-    
-    if event['cap'] == 'contact':
-        handle_contact(event)
-    elif event['cap'] == 'thermostat':
-        handle_thermostat(event)
-
-# Publish commands (within async context)
-await mqtt_client.publish_set_thermostat("thermostat_id", 22.5)
-```
-
-**Subscriptions:**
-- `home/contact/+/state` - All contact sensor state changes
-- `home/thermostat/+/state` - All thermostat state changes
-
-**Publishing:**
-- Topic: `home/thermostat/{device_id}/set`
-- Payload: `{"type":"thermostat","payload":{"target":22.5}}`
-- QoS: 1 (at least once delivery)
-
-**Robustness:**
-- Automatic reconnection with exponential backoff
-- Connection logging (connect/disconnect events)
-- Clean session handling
-
-### 4. MQTTPublisher (Legacy)
-
-Simplified wrapper around MQTTClient for backward compatibility:
-
-```python
-# Set thermostat temperature
-await ctx.mqtt.publish_set_thermostat("thermostat_wohnzimmer", 21.5)
-```
-
-### 5. RuleContext
-
-Runtime context provided to rules:
-
-```python
-class RuleContext:
-    logger           # Logger instance
-    mqtt             # MQTTPublisher
-    redis            # RedisState
-    now() -> datetime  # Current timestamp
-```
-
-### 5. Rule Abstract Base Class
-
-All rules extend this:
-
-```python
-class MyRule(Rule):
-    async def on_event(self, evt: dict, desc: RuleDescriptor, ctx: RuleContext) -> None:
-        # Event structure:
-        # {
-        #     "topic": "home/contact/device_id/state",
-        #     "type": "state",
-        #     "cap": "contact",
-        #     "device_id": "kontakt_wohnzimmer",
-        #     "payload": {"contact": "open"},
-        #     "ts": "2025-11-11T10:30:45.123456"
-        # }
-        
-        device_id = evt['device_id']
-        cap = evt['cap']
-        
-        if cap == 'contact':
-            contact_state = evt['payload'].get('contact')
-            # ... implement logic
-```
-
-## Implementing a New Rule
-
-### Step 1: Create Rule Class
-
-```python
-from packages.rule_interface import Rule, RuleDescriptor, RuleContext
-from typing import Any
-
-class MyCustomRule(Rule):
-    """My custom automation rule."""
-    
-    async def on_event(
-        self,
-        evt: dict[str, Any],
-        desc: RuleDescriptor,
-        ctx: RuleContext
-    ) -> None:
-        """Process device state changes."""
-        
-        # 1. Extract event data
-        device_id = evt['device_id']
-        cap = evt['cap']
-        payload = evt['payload']
-        
-        # 2. Filter to relevant devices
-        if device_id not in desc.targets.get('my_devices', []):
-            return
-        
-        # 3. Implement logic
-        if cap == 'contact':
-            if payload.get('contact') == 'open':
-                # Do something
-                await ctx.mqtt.publish_set_thermostat(
-                    'some_thermostat',
-                    desc.params.get('temp', 20.0)
-                )
-        
-        # 4. Persist state if needed
-        state_key = f"rule:{desc.id}:device:{device_id}:state"
-        await ctx.redis.set(state_key, payload.get('contact'))
-```
-
-### Step 2: Register in RULE_IMPLEMENTATIONS
-
-```python
-# In your rule module (e.g., my_custom_rule.py)
-RULE_IMPLEMENTATIONS = {
-    'my_custom@1.0': MyCustomRule,
-}
-```
-
-### Step 3: Configure in rules.yaml
-
-```yaml
-rules:
-  - id: my_custom_living_room
-    name: My Custom Rule for Living Room
-    type: my_custom@1.0
-    targets:
-      my_devices:
-        - device_1
-        - device_2
-    params:
-      temp: 22.0
-      duration_secs: 300
-```
-
-## Best Practices
-
-### Idempotency
-
-Rules MUST be idempotent - processing the same event multiple times should be safe:
-
-```python
-# Good: Idempotent
-async def on_event(self, evt, desc, ctx):
-    if evt['payload'].get('contact') == 'open':
-        await ctx.mqtt.publish_set_thermostat('thermo', 16.0)
-
-# Bad: Not idempotent (increments counter)
-async def on_event(self, evt, desc, ctx):
-    counter = await ctx.redis.get('counter') or '0'
-    await ctx.redis.set('counter', str(int(counter) + 1))
-```
-
-### Error Handling
-
-Handle errors gracefully - the engine will catch and log exceptions:
-
-```python
-async def on_event(self, evt, desc, ctx):
-    try:
-        await ctx.mqtt.publish_set_thermostat('thermo', 16.0)
-    except Exception as e:
-        ctx.logger.error(f"Failed to set thermostat: {e}")
-        # Don't raise - let event processing continue
-```
-
-### State Keys
-
-Use consistent naming for Redis keys:
-
-```python
-# Pattern: rule:{rule_id}:{category}:{device_id}:{field}
-state_key = f"rule:{desc.id}:contact:{device_id}:state"
-ts_key = f"rule:{desc.id}:contact:{device_id}:ts"
-prev_key = f"rule:{desc.id}:thermo:{device_id}:previous"
-```
-
-### Logging
-
-Use appropriate log levels:
-
-```python
-ctx.logger.debug("Detailed diagnostic info")
-ctx.logger.info("Normal operation milestones")
-ctx.logger.warning("Unexpected but handled situations")
-ctx.logger.error("Errors that prevent operation")
-```
-
-## Event Structure Reference
-
-### Contact Sensor Event
-
-```python
-{
-    "topic": "home/contact/kontakt_wohnzimmer/state",
-    "type": "state",
-    "cap": "contact",
-    "device_id": "kontakt_wohnzimmer",
-    "payload": {

-
-## Testing Rules
-
-Rules can be tested independently of the engine:
-
-```python
-import pytest
-from unittest.mock import AsyncMock, MagicMock
-from packages.my_custom_rule import MyCustomRule
-from packages.rule_interface import RuleDescriptor, RuleContext
-
-@pytest.mark.asyncio
-async def test_my_rule():
-    # Setup
-    rule = MyCustomRule()
-    
-    desc = RuleDescriptor(
-        id="test_rule",
-        type="my_custom@1.0",
-        targets={"my_devices": ["device_1"]},
-        params={"temp": 22.0}
-    )
-    
-    # Mock context
-    ctx = RuleContext(
-        logger=MagicMock(),
-        mqtt_publisher=AsyncMock(),
-        redis_state=AsyncMock(),
-        now_fn=lambda: datetime.now()
-    )
-    
-    # Test event
-    evt = {
-        "device_id": "device_1",
-        "cap": "contact",
-        "payload": {"contact": "open"},
-        "ts": "2025-11-11T10:30:45.123456"
-    }
-    
-    # Execute
-    await rule.on_event(evt, desc, ctx)
-    
-    # Assert
-    ctx.mqtt.publish_set_thermostat.assert_called_once_with('some_thermostat', 22.0)
-```
-
-## Extension Points
-
-The interface is designed to be extended without modifying the engine:
-
-1. **New rule types**: Just implement `Rule` and register in `RULE_IMPLEMENTATIONS`
-2. **New MQTT commands**: Extend `MQTTPublisher` with new methods
-3. **New state backends**: Implement `RedisState` interface with different storage
-4. **Custom context**: Extend `RuleContext` with additional utilities
-
-The engine only depends on the abstract interfaces, not specific implementations.

+# Home Automation API Client
+
+Wiederverwendbare JavaScript-API-Client-Bibliothek für das Home Automation UI.
+
+## Installation
+
+Füge die folgenden Script-Tags in deine HTML-Seiten ein:
+
+```html
+<script src="/static/types.js"></script>
+<script src="/static/api-client.js"></script>
+```
+
+## Konfiguration
+
+Der API-Client nutzt `window.API_BASE`, das vom Backend gesetzt wird:
+
+```javascript
+window.API_BASE = '{{ api_base }}';  // Jinja2 template
+```
+
+## Verwendung
+
+### Globale Instanz
+
+Der API-Client erstellt automatisch eine globale Instanz `window.apiClient`:
+
+```javascript
+// Layout abrufen
+const layout = await window.apiClient.getLayout();
+
+// Geräte abrufen
+const devices = await window.apiClient.getDevices();
+
+// Gerätestatus abrufen
+const state = await window.apiClient.getDeviceState('kitchen_light');
+
+// Gerätesteuerung
+await window.apiClient.setDeviceState('kitchen_light', 'light', {
+    power: true,
+    brightness: 80
+});
+```
+
+### Verfügbare Methoden
+
+#### `getLayout(): Promise<Layout>`
+Lädt die Layout-Daten (Räume und ihre Geräte).
+
+```javascript
+const layout = await window.apiClient.getLayout();
+// { rooms: [{name: "Küche", devices: ["kitchen_light", ...]}, ...] }
+```
+
+#### `getDevices(): Promise<Device[]>`
+Lädt alle Geräte mit ihren Features.
+
+```javascript
+const devices = await window.apiClient.getDevices();
+// [{device_id: "...", name: "...", type: "light", features: {...}}, ...]
+```
+
+#### `getDeviceState(deviceId): Promise<DeviceState>`
+Lädt den aktuellen Status eines Geräts.
+
+```javascript
+const state = await window.apiClient.getDeviceState('kitchen_light');
+// {power: true, brightness: 80, ...}
+```
+
+#### `getAllStates(): Promise<Object>`
+Lädt alle Gerätestatus auf einmal.
+
+```javascript
+const states = await window.apiClient.getAllStates();
+// {"kitchen_light": {power: true, ...}, "thermostat_1": {...}, ...}
+```
+
+#### `setDeviceState(deviceId, type, payload): Promise<void>`
+Sendet einen Befehl an ein Gerät.
+
+```javascript
+// Licht einschalten
+await window.apiClient.setDeviceState('kitchen_light', 'light', {
+    power: true,
+    brightness: 80
+});
+
+// Thermostat einstellen
+await window.apiClient.setDeviceState('thermostat_1', 'thermostat', {
+    target_temp: 22.5
+});
+
+// Rollladen steuern
+await window.apiClient.setDeviceState('cover_1', 'cover', {
+    position: 50
+});
+```
+
+#### `getDeviceRoom(deviceId): Promise<{room: string}>`
+Ermittelt den Raum eines Geräts.
+
+```javascript
+const { room } = await window.apiClient.getDeviceRoom('kitchen_light');
+// {room: "Küche"}
+```
+
+#### `getScenes(): Promise<Scene[]>`
+Lädt alle verfügbaren Szenen.
+
+```javascript
+const scenes = await window.apiClient.getScenes();
+```
+
+#### `activateScene(sceneId): Promise<void>`
+Aktiviert eine Szene.
+
+```javascript
+await window.apiClient.activateScene('evening');
+```
+
+### Realtime-Updates (SSE)
+
+#### `connectRealtime(onEvent, onError): EventSource`
+Verbindet sich mit dem SSE-Stream für Live-Updates.
+
+```javascript
+window.apiClient.connectRealtime(
+    (event) => {
+        console.log('Update:', event.device_id, event.state);
+        // event = {device_id: "...", type: "state", state: {...}}
+    },
+    (error) => {
+        console.error('Connection error:', error);
+    }
+);
+```
+
+#### `onDeviceUpdate(deviceId, callback): Function`
+Registriert einen Listener für spezifische Geräte-Updates.
+
+```javascript
+// Für ein bestimmtes Gerät
+const unsubscribe = window.apiClient.onDeviceUpdate('kitchen_light', (event) => {
+    console.log('Kitchen light changed:', event.state);
+    updateUI(event.state);
+});
+
+// Für alle Geräte
+const unsubscribeAll = window.apiClient.onDeviceUpdate(null, (event) => {
+    console.log('Any device changed:', event.device_id, event.state);
+});
+
+// Später: Listener entfernen
+unsubscribe();
+```
+
+#### `disconnectRealtime(): void`
+Trennt die SSE-Verbindung und entfernt alle Listener.
+
+```javascript
+window.apiClient.disconnectRealtime();
+```
+
+### Helper-Methoden
+
+#### `findDevice(devices, deviceId): Device|null`
+Findet ein Gerät in einem Array.
+
+```javascript
+const devices = await window.apiClient.getDevices();
+const device = window.apiClient.findDevice(devices, 'kitchen_light');
+```
+
+#### `findRoom(layout, roomName): Room|null`
+Findet einen Raum im Layout.
+
+```javascript
+const layout = await window.apiClient.getLayout();
+const room = window.apiClient.findRoom(layout, 'Küche');
+```
+
+#### `getDevicesForRoom(layout, devices, roomName): Device[]`
+Gibt alle Geräte eines Raums zurück.
+
+```javascript
+const layout = await window.apiClient.getLayout();
+const devices = await window.apiClient.getDevices();
+const kitchenDevices = window.apiClient.getDevicesForRoom(layout, devices, 'Küche');
+```
+
+#### `api(path): string`
+Konstruiert eine vollständige API-URL.
+
+```javascript
+const url = window.apiClient.api('/devices');
+// "http://172.19.1.11:8001/devices"
+```
+
+### Backward Compatibility
+
+Die globale `api()` Funktion ist weiterhin verfügbar:
+
+```javascript
+function api(url) {
+    return window.apiClient.api(url);
+}
+```
+
+## Typen (JSDoc)
+
+Die Datei `types.js` enthält JSDoc-Definitionen für alle API-Typen:
+
+- `Room` - Raum mit Geräten
+- `Layout` - Layout-Struktur
+- `Device` - Gerätedaten
+- `DeviceFeatures` - Geräte-Features
+- `DeviceState` - Gerätestatus (Light, Thermostat, Contact, etc.)
+- `RealtimeEvent` - SSE-Event-Format
+- `Scene` - Szenen-Definition
+- `*Payload` - Command-Payloads für verschiedene Gerätetypen
+
+Diese ermöglichen IDE-Autocomplete und Type-Checking in modernen Editoren (VS Code, WebStorm).

+            // Load initial state
+            const state = await window.apiClient.getDeviceState(deviceId);
+            updateUI(state);
+
+            // Listen for updates
+            window.apiClient.onDeviceUpdate(deviceId, (event) => {
+                updateUI(event.state);
+            });
+
+            // Connect to realtime
+            window.apiClient.connectRealtime((event) => {
+                console.log('Event:', event);
+            });
+
+            // Handle button clicks
+            document.getElementById('toggle').onclick = async () => {
+                const currentState = await window.apiClient.getDeviceState(deviceId);
+                await window.apiClient.setDeviceState(deviceId, 'light', {
+                    power: !currentState.power
+                });
+            };
+        }
+
+        function updateUI(state) {

+                state.power ? 'ON' : 'OFF';
+        }
+
+        init();
+    </script>
+</body>
+</html>
+```
+
+## Error Handling
+
+Alle API-Methoden werfen Exceptions bei Fehlern:
+
+```javascript
+try {
+    const state = await window.apiClient.getDeviceState('invalid_id');
+} catch (error) {
+    console.error('API error:', error);
+    showErrorMessage(error.message);
+}
+```
+
+## Auto-Reconnect
+
+Der SSE-Client versucht automatisch, nach 5 Sekunden wieder zu verbinden, wenn die Verbindung abbricht.

-# Device Simulator
-
-Unified MQTT device simulator für das Home Automation System.
-
-## Übersicht
-
-Dieser Simulator ersetzt die einzelnen Simulatoren (`sim_test_lampe.py`, `sim_thermo.py`) und vereint alle Device-Typen in einer einzigen Anwendung.
-
-## Unterstützte Geräte
-
-### Lampen (3 Geräte)
-- `test_lampe_1` - Mit Power und Brightness
-- `test_lampe_2` - Mit Power und Brightness  
-- `test_lampe_3` - Mit Power und Brightness
-
-**Features:**
-- `power`: "on" oder "off"
-- `brightness`: 0-100
-
-### Thermostaten (1 Gerät)
-- `test_thermo_1` - Vollständiger Thermostat mit Temperatur-Simulation
-
-**Features:**
-- `mode`: "off", "heat", oder "auto"
-- `target`: Soll-Temperatur (5.0-30.0°C)
-- `current`: Ist-Temperatur (wird simuliert)
-- `battery`: Batteriestand (90%)
-- `window_open`: Fensterstatus (false)
-
-**Temperatur-Simulation:**
-- Alle 5 Sekunden wird die Ist-Temperatur angepasst
-- **HEAT/AUTO Mode**: Drift zu `target` (+0.2°C pro Intervall)
-- **OFF Mode**: Drift zu Ambient-Temperatur 18°C (-0.2°C pro Intervall)
-
-## MQTT-Konfiguration
-
-- **Broker**: 172.16.2.16:1883 (konfigurierbar via ENV)
-- **QoS**: 1 für alle Publishes
-- **Retained**: Ja für alle State-Messages
-- **Client ID**: device_simulator
-
-### Topics
-
-Für jedes Gerät:
-- Subscribe: `vendor/{device_id}/set` (QoS 1)
-- Publish: `vendor/{device_id}/state` (QoS 1, retained)
-
-## Verwendung
-
-### Starten
-
-```bash
-poetry run python tools/device_simulator.py
-```
-
-Oder im Hintergrund:
-
-```bash
-poetry run python tools/device_simulator.py > /tmp/simulator.log 2>&1 &
-```
-
-### Umgebungsvariablen
-
-```bash
-export MQTT_BROKER="172.16.2.16"  # MQTT Broker Host
-export MQTT_PORT="1883"           # MQTT Broker Port
-```
-
-## Testen
-
-Ein umfassendes Test-Skript ist verfügbar:
-
-```bash
-./tools/test_device_simulator.sh
-```
-
-Das Test-Skript:
-1. Stoppt alle laufenden Services
-2. Startet Abstraction Layer, API und Simulator
-3. Testet alle Lampen-Operationen
-4. Testet alle Thermostat-Operationen
-5. Verifiziert MQTT State Messages
-6. Zeigt Simulator-Logs
-
-## Beispiele
-
-### Lampe einschalten
-
-```bash
-curl -X POST http://localhost:8001/devices/test_lampe_1/set \
-  -H "Content-Type: application/json" \
-  -d '{"type":"light","payload":{"power":"on"}}'
-```
-
-### Helligkeit setzen
-
-```bash
-curl -X POST http://localhost:8001/devices/test_lampe_1/set \
-  -H "Content-Type: application/json" \
-  -d '{"type":"light","payload":{"brightness":75}}'
-```
-
-### Thermostat Mode setzen
-
-```bash
-curl -X POST http://localhost:8001/devices/test_thermo_1/set \
-  -H "Content-Type: application/json" \
-  -d '{"type":"thermostat","payload":{"mode":"heat","target":22.5}}'
-```
-
-### State abfragen via MQTT
-
-```bash
-# Lampe
-mosquitto_sub -h 172.16.2.16 -t 'vendor/test_lampe_1/state' -C 1
-
-# Thermostat
-mosquitto_sub -h 172.16.2.16 -t 'vendor/test_thermo_1/state' -C 1
-```
-
-## Architektur
-
-```
-Browser/API
-    ↓ POST /devices/{id}/set
-API Server (Port 8001)
-    ↓ MQTT: home/{type}/{id}/set
-Abstraction Layer
-    ↓ MQTT: vendor/{id}/set
-Device Simulator
-    ↓ MQTT: vendor/{id}/state (retained)
-Abstraction Layer
-    ↓ MQTT: home/{type}/{id}/state (retained)
-    ↓ Redis Pub/Sub: ui:updates
-UI / Dashboard
-```
-
-## Logs
-
-Der Simulator loggt alle Aktivitäten:
-- Startup und MQTT-Verbindung
-- Empfangene SET-Commands
-- State-Änderungen
-- Temperature-Drift (Thermostaten)
-- Publizierte State-Messages
-
-Log-Level: INFO
-
-## Troubleshooting
-
-### Simulator startet nicht
-
-```bash
-# Prüfe ob Port bereits belegt
-lsof -ti:1883
-
-# Prüfe MQTT Broker
-mosquitto_sub -h 172.16.2.16 -t '#' -C 1
-```
-
-### Keine State-Updates
-
-```bash
-# Prüfe Simulator-Log
-tail -f /tmp/simulator.log
-
-# Prüfe MQTT Topics
-mosquitto_sub -h 172.16.2.16 -t 'vendor/#' -v
-```
-
-### API antwortet nicht
-
-```bash
-# Prüfe ob API läuft
-curl http://localhost:8001/devices
-
-# Prüfe API-Log
-tail -f /tmp/api.log
-```
-
-## Integration
-
-Der Simulator integriert sich nahtlos in das Home Automation System:
-
-1. **Abstraction Layer** empfängt Commands und sendet sie an Simulator
-2. **Simulator** reagiert und publiziert neuen State
-3. **Abstraction Layer** empfängt State und publiziert zu Redis
-4. **UI** empfängt Updates via SSE und aktualisiert Dashboard
-
-Alle Komponenten arbeiten vollständig asynchron über MQTT.
