 # SillyHome Next
 
-Lokaler, datenschutzfreundlicher API-Prototyp für Home Assistant.
-
-## Reifegrad
-
-Die aktuelle Entwicklungslinie stellt eine gehärtete technische Basis bereit:
-Home-Assistant-Entities und Historie lesen, Sensoren klassifizieren,
-regelbasierte Bausteine sowie ein lokal trainierbares statistisches
-Baseline-Modell mit persistenter Registry, Confidence und echten
-Evaluationsmetriken.
+Modern, lokal-first und datenschutzfreundliches Smart-Home-Intelligenzsystem für Home Assistant.
 
 ## Motivation
 TheSillyHome zeigte die Idee: statt statischer Regeln das Zuhause aus Verhaltensmustern verstehen. Diese Architektur modernisiert den Ansatz in Richtung Explainable AI, hybride Intelligenzebenen und langlebige Wartbarkeit.
@@ -20,59 +12,3 @@ TheSillyHome zeigte die Idee: statt statischer Regeln das Zuhause aus Verhaltens
 - Automationen vorschlagen und direkt generieren
 - Lokal-first ohne Cloudpflicht
 - Erweiterbar, testbar, dokumentiert
-
-## Quickstart
-1. Python-Venv anlegen und Abhängigkeiten installieren:
-```bash
-python -m venv .venv
-source .venv/bin/activate
-pip install -e ".[dev]"
-```
-
-2. Konfiguration aus `.env.example` übernehmen und anpassen:
-```bash
-cp .env.example .env
-```
-
-3. API starten:
-```bash
-uvicorn app.main:app --reload
-```
-
-4. Erreichbar unter:
-- `http://127.0.0.1:8000/health` - Health-Check
-- `http://127.0.0.1:8000/docs/` - OpenAPI-Dokumentation
-- `http://127.0.0.1:8000/v1/entities` - Home-Assistant-Entities
-- `http://127.0.0.1:8000/v1/discovery` - klassifizierte, filterbare Entities
-- `http://127.0.0.1:8000/v1/history` - normalisierte numerische Zeitreihen
-- `http://127.0.0.1:8000/ml/health` - Registry-/Serving-Health
-- `POST http://127.0.0.1:8000/ml/retrain` - Modell-Metadaten aktualisieren
-- `POST http://127.0.0.1:8000/ml/evaluate` - MAE/RMSE/Coverage berechnen
-
-Ohne vollständige HA-Konfiguration liefert `/v1/entities` bewusst `503`.
-
-### Docker Compose
-
-```bash
-cp .env.example .env
-docker compose up --build -d
-curl --fail http://127.0.0.1:8000/health
-```
-
-Compose veröffentlicht die API standardmäßig nur auf `127.0.0.1`. Für Zugriff aus
-dem Netz muss ein authentifizierender Reverse Proxy vorgeschaltet werden.
-
-### ENV-Konfiguration (`.env.example`)
-- `SILLYHOME_HA_URL` – Basis-URL deiner Home-Assistant-Instanz (z. B. `http://homeassistant.local:8123`)
-- `SILLYHOME_HA_TOKEN` – Long-Lived Access Token eines dedizierten HA-Benutzers mit minimalen Rechten
-- `SILLYHOME_MODEL_STORE` – Verzeichnis für persistierte Modell-Metadaten
-
-Niemals Administrator-Tokens oder Passwörter eintragen. `.env` gehört nicht ins
-Versionskontrollsystem.
-
-### Tests
-```bash
-pytest
-ruff check .
-mypy
-```

-# Home-Assistant-Datenpipeline
-
-SillyHome Next trennt aktuelle Entity-Metadaten, Discovery und historische
-Messwerte. Dadurch gelangen nur klassifizierte, geeignete Daten in spätere
-Trainings- und Erklärungsprozesse.
-
-## Entity Discovery
-
-`GET /v1/discovery` klassifiziert Home-Assistant-Entities in:
-
-- `measurement`: numerische Messsensoren, für Training geeignet
-- `binary_context`: binäre Kontextsensoren wie Bewegung oder Anwesenheit
-- `context`: Personen-, Wetter- und Standortkontext
-- `actuator`: mögliche Automationsziele, nicht als Trainingssensor verwendet
-- `unsupported`: noch nicht klassifizierte Entity-Typen
-
-Optionale Query-Parameter:
-
-- `domain=sensor` kann mehrfach angegeben werden
-- `learnable=true|false` filtert nach Trainingsrelevanz
-
-## Historische Daten
-
-Historische Zustände werden über Home Assistants
-`/api/history/period/<start>`-Schnittstelle geladen. Abfragen verlangen:
-
-- mindestens eine Entity-ID, maximal 100
-- zeitzonenbehaftete Start- und Endzeit
-- ein Enddatum nach dem Startdatum
-- maximal 31 Tage pro Abfrage
-
-Die Normalisierung übernimmt nur endliche numerische Zustände. `unknown`,
-`unavailable`, nichtnumerische Werte, `NaN` und unendliche Werte werden nicht
-als Trainingsdaten verwendet. Ergebnisse werden je Entity chronologisch
-sortiert.
-
-## Datenschutz und Betrieb
-
-Die Daten bleiben lokal. Home-Assistant-Tokens gehören ausschließlich in die
-Umgebungskonfiguration und dürfen nicht protokolliert oder versioniert werden.
-Die API sollte nur lokal oder hinter einem authentifizierenden Reverse Proxy
-erreichbar sein.

-# ML-Serving-API
-
-Diese Dokumentation beschreibt die REST-Endpunkte der aktuellen

-```
-
-### `POST /ml/evaluate`
-
-Vergleicht Modellvorhersagen mit Validierungsdaten und liefert MAE, RMSE und

-## Fehlerfälle
-
-- `404 Not Found`: Modell nicht registriert.
-- `422 Unprocessable Content`: Sensor wird vom Modell nicht unterstützt oder Eingabe ist ungültig.
-- `503 Service Unavailable`: Registry ist nicht initialisiert.
-
-## Betrieb
-
-Die produktive App lädt Artefakte aus `SILLYHOME_MODEL_STORE`. Neue Artefakte
-werden über `/ml/retrain`, `RetrainingService` oder direkt über
-`ModelRegistry.register(...)` registriert. Die Registry speichert validiertes
-JSON atomisch und lädt es beim Neustart. Die API sollte nur in einem
-vertrauenswürdigen Netz oder hinter einem authentifizierenden Reverse Proxy
-erreichbar sein.

-# ML Training- und Evaluations-Workflow
-
-SillyHome Next trainiert ein lokales statistisches Baseline-Modell pro Sensor
-und Merkmal. Es benötigt keine Cloud und keine externe ML-Laufzeit.
-
-## 1. Daten sammeln
-
-Alle Trainingsvektoren werden über `FeatureStore.add(...)` oder `add_batch(...)` eingepflegt. Jeder Vektor enthält eine Sensor-ID sowie ein Dictionary mit Merkmalen.
-
-## 2. Statistisches Artefakt erzeugen
-
-```python
-store = FeatureStore()
-store.add(FeatureVector(sensor_id="sensor.kitchen", values={"temperature": 21.0}))
-pipeline = TrainingPipeline(store)
-artifact = pipeline.run("my_artifact")
-pipeline.export("my_artifact")
-```
-
-`TrainingPipeline.run(...)` berechnet für jedes numerische Merkmal:
-
-- Stichprobenzahl
-- Mittelwert und Standardabweichung
-- Minimum und Maximum
-- linearen Trend mit Steigung und Achsenabschnitt
-
-Die nächste Vorhersage kombiniert den letzten beobachteten Wert mit der
-trainierten Trendsteigung. Die Confidence berücksichtigt Datenmenge und
-Stabilität.
-
-## 3. Modell evaluieren
-
-```python
-evaluator = Evaluator(pipeline)
-report = evaluator.evaluate(artifact.artifact_id, validation_samples)
-```
-
-Der Report enthält echte numerische Vergleichsmetriken:
-- `artifact_id`
-- `sample_size`
-- `mae` (Mean Absolute Error)
-- `rmse` (Root Mean Squared Error)
-- `coverage` für den Anteil auswertbarer Merkmale
-
-## 4. Modell registrieren
-
-Das trainierte Artefakt kann anschließend über `ModelRegistry.register(artifact)` bereitgestellt werden. Die ML-Serving-API stellt es unter `/ml/predict` und `/ml/batch` zur Verfügung.
-
-## 5. Retraining ausführen
-
-`RetrainingService.retrain(...)` führt genau einen Trainingslauf aus und ersetzt
-ein vorhandenes Artefakt mit derselben ID atomisch in der Registry:
-
-```python
-service = RetrainingService(registry)
-result = service.retrain("home-model", vectors)
-```
-
-Scheduler, Cronjobs oder Home-Assistant-Automationen können alternativ die
-zustandslose Funktion `retrain_model(registry, artifact_id, vectors)` aufrufen.
-Der Service startet bewusst keinen eigenen Hintergrundprozess. Über
-`POST /ml/retrain` kann derselbe Ablauf per API angestoßen werden.
-
-## Hinweise
-- Für reproduzierbare Sensor-Reihenfolgen wird in `TrainingPipeline.run(...)` eine sortierte Sensor-Liste verwendet.
-- Fehlende Trainingsdaten lösen `ValueError` aus; nicht registrierte Artefakte lösen `KeyError` aus.
-- Nur endliche numerische Werte werden trainiert.
-- `coverage` bleibt im Bereich 0 bis 1.
