fix: MQTT topic matching + UI button fixes

- Fix MQTT topic pattern matching (_mqtt_topic_matches):
  * Implement proper # wildcard (multi-level)
  * Implement proper + wildcard (single-level)
  * Fix bug where first device got ALL messages
  * Now shaperorigin/# only matches shaperorigin/* topics

- Fix Stop Connection button (Odoo-style):
  * Remove manual commit() - let Odoo handle it
  * Use write() to update state
  * Handle case where service doesn't have connection

- Fix Test Connection hanging:
  * Add proper cleanup with sleep after disconnect
  * Catch cleanup exceptions

- Add @unittest.skip to real MQTT tests:
  * TransactionCase incompatible with paho-mqtt threads
  * See TODO.md M8 for details

- Fix run-tests.sh:
  * Remove -i flag (was hanging)
  * Simplify to direct output redirect

- Add TODO.md documentation
- Update .gitignore for test logs

+# TODO - Open Workshop MQTT (Stand: 28. Januar 2026)
+
+## Status-Übersicht
+
+### ✅ Phase 1: Python Prototyp (ABGESCHLOSSEN)
+- [x] M0: Projekt Setup & MQTT Verbindung
+- [x] M1: Shelly PM Mini G3 Integration
+- [x] M2: Event-Normalisierung & Unified Schema
+- [x] M3: Session Detection Engine
+- [x] M4: Multi-Device Support & Config
+- [x] M5: Monitoring & Robustheit
+- [x] Unit Tests (pytest)
+- [x] Integration Tests (mit echtem MQTT Broker)
+
+**Ergebnis:** `python_prototype/` ist vollständig implementiert und getestet
+
+---
+
+### 🚧 Phase 2: Odoo Integration (IN ARBEIT - 70% fertig)
+
+**Architektur:** Odoo macht ALLES direkt (kein REST API, keine externe Bridge)
+```
+Shelly PM → MQTT Broker → Odoo (MQTT Client) → Session Detection → Sessions
+```
+
+#### ✅ M6: Odoo Modul Grundgerüst (FERTIG - 100%)
+- [x] Modul `open_workshop_mqtt` erstellt
+- [x] Models implementiert:
+  - [x] `mqtt.connection` - MQTT Broker Verbindungen
+  - [x] `mqtt.device` - IoT Device Management
+  - [x] `mqtt.session` - Runtime Sessions
+  - [x] `mqtt.message` - Message Log (Debug)
+- [x] Views erstellt (List, Form, Kanban, Pivot, Graph)
+- [x] Security Rules (`ir.model.access.csv`)
+- [x] Services:
+  - [x] `mqtt_client.py` - MQTT Client (mit TLS, Auto-Reconnect)
+  - [x] `iot_bridge_service.py` - Singleton Service für Connection Management
+  - [x] **MQTT Client in Odoo** - Subscribed DIREKT auf MQTT Topics ✅
+- [x] Parsers:
+  - [x] `shelly_parser.py` - Shelly PM Mini G3
+  - [x] Generic Parser Support
+
+**Code-Location:** `/models/`, `/services/`, `/views/`
+
+**Flow:** Shelly → MQTT → Odoo (kein REST API nötig!)
+
+---
+
+#### ~~❌ M7: REST Endpoint & Authentication~~ (GESTRICHEN!)
+
+**Begründung:** Odoo hat bereits MQTT Client → REST API überflüssig!
+
+**NICHT NÖTIG** weil:
+- Odoo subscribed DIREKT auf MQTT Topics (via `mqtt_client.py`)
+- Keine externe Bridge erforderlich
+- `python_prototype/` bleibt als Standalone-Tool für Tests/Entwicklung
+
+---
+
+#### ~~❌ M8: Python-Bridge Integration~~ (GESTRICHEN!)
+
+**Begründung:** Python Prototype bleibt Standalone für Tests. Odoo macht Production!
+
+---
+
+#### 🚧 M7: Session-Engine in Odoo (TEILWEISE FERTIG - 20%) [war M9]
+
+**Was funktioniert:**
+- [x] `mqtt.session` Model existiert
+- [x] Basic Session CRUD
+- [x] Session Views (Pivot, Graph, Analytics)
+- [x] Device-Session Verknüpfung
+- [x] **VEREINFACHTE** Session Detection in `iot_bridge_service.py:543-594`:
+  - [x] Power > 0 → Session start
+  - [x] Power == 0 → Session end
+  - [x] Duration Tracking (total_duration_s)
+
+**Was FEHLT (kritisch):**
+- [ ] **RICHTIGE Session Detection Logic** (aus Python Prototype übernehmen):
+  ```
+  Aktuell: power > 0 → start, power == 0 → end (ZU SIMPEL!)
+  Benötigt: Dual-Threshold State Machine aus session_detector.py
+  
+  ⚠️ WICHTIG: strategy_config EXISTIERT in UI + Model + Validation,
+             wird aber in _process_session() IGNORIERT!
+  ```
+  - [ ] Dual-Threshold Detection:
+    - [ ] Standby Threshold (z.B. 20W) - Maschine an, Spindel aus
+    - [ ] Working Threshold (z.B. 100W) - Spindel läuft
+    - ✅ UI Field existiert (mqtt_device_views.xml:106 - JSON Editor)
+    - ✅ Validation existiert (mqtt_device.py:195)
+    - ❌ Wird NICHT verwendet in _process_session()!
+  - [ ] Debounce Timer:
+    - [ ] Start Debounce (3s) - Power muss 3s über Threshold bleiben
+    - [ ] Stop Debounce (15s) - Power muss 15s unter Threshold bleiben
+    - ✅ In strategy_config definiert
+    - ❌ Wird NICHT verwendet!
+  - [ ] State Machine (5 States):
+    ```
+    IDLE → STARTING (debounce) → STANDBY/WORKING → STOPPING (debounce) → IDLE
+    ```
+  - [ ] Timeout Detection (20s keine Messages → Session end)
+    - ✅ message_timeout_s in strategy_config
+    - ❌ Wird NICHT geprüft!
+  - [ ] Duration Tracking:
+    - [ ] standby_duration_s (Zeit in Standby)
+    - [ ] working_duration_s (Zeit in Working - das ist die eigentliche Laufzeit!)
+  - [ ] State Recovery nach Odoo Restart
+  - [ ] `end_reason` Logic (normal/timeout/power_drop)
+
+**Aktueller Code-Location:**
+- ✅ Vereinfacht: `services/iot_bridge_service.py:543` (`_process_session()`)
+- ✅ UI + Validation: `models/mqtt_device.py` + `views/mqtt_device_views.xml:106`
+- ✅ Helper: `device.get_strategy_config_dict()` existiert
+- ❌ FEHLT: State Machine + strategy_config wird NICHT verwendet!
+
+**Implementation:**
+1. [ ] **Session Detector Service** portieren
+   - File: `services/session_detector.py`
+   - Class `SessionDetector` (aus Python Prototype)
+   - States: IDLE, STARTING, STANDBY, WORKING, STOPPING
+   - Config aus `mqtt.device.strategy_config` lesen
+
+2. [ ] **Integration in `iot_bridge_service.py`**
+   - `_process_session()` ersetzen durch SessionDetector
+   - Timeout Check Worker (jede Sekunde)
+   - State Recovery nach Restart
+
+3. [ ] **Session Model erweitern**
+   - Fields: `standby_duration_s`, `working_duration_s`
+   - Field: `state` (idle/starting/standby/working/stopping)
+   - Computed: `actual_working_time` (= working_duration_s)
+
+**Tests (parallel entwickeln):**
+- [ ] `test_session_detector.py`:
+  - [ ] test_idle_to_starting_transition()
+  - [ ] test_start_debounce_timer()
+  - [ ] test_standby_to_working_transition()
+  - [ ] test_stop_debounce_timer()
+  - [ ] test_timeout_detection()
+  - [ ] test_state_recovery_after_restart()
+  - [ ] test_duration_tracking()
+- [ ] `test_session_integration.py`:
+  - [ ] test_full_session_cycle() (MQTT → Session mit Debounce)
+  - [ ] test_session_timeout_scenario()
+
+**Code zu portieren:**
+- `python_prototype/session_detector.py` (515 Zeilen) → `services/session_detector.py`
+
+**Datei-Struktur:**
+```
+/services/session_detector.py       # Portiert aus Python
+/services/iot_bridge_service.py     # _process_session() erweitern
+/models/mqtt_session.py              # Fields erweitern
+/tests/test_session_detector.py     # Tests!
+/tests/test_session_integration.py  # Tests!
+```
+
+**Feature Request Referenz:** Section 6 (Verarbeitungslogik), Anhang C (Shelly Examples)
+
+---
+
+#### 🚧 M8: Test-Infrastruktur reparieren (BLOCKIERT - 0.5 Tag) [war M10]
+
+**Problem:**
+- Alte Tests mit echtem MQTT Broker hängen in TransactionCase
+- `test_mqtt_mocked.py` erstellt, aber nicht aktiv
+
+**TODO:**
+1. [ ] **Alte hängende Tests deaktivieren**
+   ```bash
+   cd tests/
+   mv test_mqtt_connection.py DISABLED_test_mqtt_connection.py
+   mv test_device_status.py DISABLED_test_device_status.py
+   mv test_session_detection.py DISABLED_test_session_detection.py
+   mv test_start_stop.py DISABLED_test_start_stop.py
+   ```
+
+2. [ ] **Mock-Tests aktivieren und testen**
+   - `test_mqtt_mocked.py` aktiv lassen
+   - `run-tests.sh` durchlaufen lassen
+   - Verifizieren: Tests laufen durch ohne Hanging
+
+3. [ ] **Test-Coverage erweitern** (parallel zu M7-M9)
+   - Tests werden bei jedem Milestone erstellt (siehe oben)
+   - Nicht am Ende, sondern während der Entwicklung!
+
+**Dokumentation (am Ende):**
+- [x] README.md erstellt
+- [x] Feature Request aktuell
+- [x] TODO.md (dieses Dokument)
+- [ ] API Dokumentation (`/docs/API.md`)
+  - Endpoint Schema (Event v1)
+  - Authentication
+  - Error Codes
+- [ ] Deployment Guide (`/docs/DEPLOYMENT.md`)
+  - Production Setup
+  - Docker Compose Example
+  - Systemd Service
+- [ ] Troubleshooting Guide (`/docs/TROUBLESHOOTING.md`)
+
+---
+
+## Zusammenfassung: Was ist implementiert vs. was fehlt?
+
+### ✅ FUNKTIONIERT (Odoo Integration)
+1. **MQTT Connection** - Broker Verbindung mit TLS, Auto-Reconnect ✅
+2. **Device Management** - Devices anlegen, konfigurieren ✅
+3. **Message Parsing** - Shelly PM Mini G3 Payloads parsen ✅
+4. **VEREINFACHTE Session Detection** - Power > 0 → Session ✅ (ABER ZU SIMPEL!)
+5. **Views & UI** - Forms, Lists, Pivot Tables, Graphs ✅
+
+### ❌ FEHLT (Nur noch 2 Dinge!)
+1. **RICHTIGE Session Detection** - Dual-Threshold State Machine fehlt ❌
+   - Aktuell: `power > 0 = start, power == 0 = end` (ZU SIMPEL!)
+   - Benötigt: Standby/Working Thresholds, Debounce, Timeout
+2. **Odoo Tests** - Tests hängen, Mocks nicht aktiv ❌
+
+### ~~NICHT MEHR NÖTIG~~
+- ~~REST API Endpoint~~ - Odoo macht MQTT direkt ✅
+- ~~Event Storage Model~~ - `mqtt.message` reicht für Debug ✅
+- ~~Python Bridge~~ - Odoo ist die Bridge ✅
+
+---
+
+## Prioritäten (Nächste Schritte)
+
+### 🔥 HIGH PRIORITY (Phase 2 abschließen - NUR NOCH 2-3 Tage!)
+
+**Reihenfolge (mit Tests!):**
+
+1. **M8: Test-Infrastruktur reparieren** (0.5 Tag - ZUERST!)
+   - Alte hängende Tests deaktivieren
+   - `run-tests.sh` zum Laufen bringen
+   - → **Dann** können wir TDD machen!
+
+2. **M7: Session-Engine portieren + Tests** (1-2 Tage)
+   - ✅ State Machine Tests → State Machine Code
+   - ✅ Debounce Tests → Debounce Logic Code
+   - ✅ Timeout Tests → Timeout Detection Code
+   - Portierung aus Python Prototype (Tests existieren bereits!)
+   - **Das ist der einzige große Brocken!**
+
+3. **Dokumentation** (0.5 Tag - parallel)
+   - Setup Guide
+   - Troubleshooting
+
+**M7+M8 (REST/Bridge) GESTRICHEN** = **2 Tage gespart!** 🎉
+
+### 🟡 MEDIUM PRIORITY (Optional M11)
+
+5. **POS Integration** (später)
+   - Realtime Display
+   - WebSocket Feed
+   - Live Power Consumption
+
+6. **Maintenance Integration**
+   - Link zu `maintenance.equipment`
+   - Usage Tracking
+   - Separate Module `open_workshop_mqtt_maintenance`
+
+### 🟢 LOW PRIORITY (Nice-to-have)
+
+7. **Performance & Scale**
+   - Last-Tests (20 Devices, 1h)
+   - Queue Optimization
+   - Database Indexes
+
+8. **Security Hardening**
+   - IP Allowlist
+   - Rate Limiting (Reverse Proxy)
+   - Token Rotation
+
+---
+
+## Bekannte Probleme
+
+### 🐛 BUGS
+
+1. **Tests hängen mit echtem MQTT Broker**
+   - Location: `tests/test_mqtt_connection.py`, etc.
+   - Reason: TransactionCase + Background Threads inkompatibel
+   - Solution: Mock-basierte Tests (erstellt, aber nicht aktiv)
+   - Status: WORKAROUND erstellt, muss aktiviert werden
+
+2. **Manual Session Start/Stop TODO**
+   - Location: `models/mqtt_device.py:327, 349`
+   - Methods: `action_start_session()`, `action_stop_session()`
+   - Status: Placeholder, nicht implementiert
+
+3. **Topic Matching ohne Wildcards**
+   - Location: `services/iot_bridge_service.py:498`
+   - TODO Comment: Implement proper topic matching (+, #)
+   - Status: Funktioniert nur mit exakten Topics
+
+### ⚠️ TECHNICAL DEBT
+
+1. **Session Detection zu simpel**
+   - Problem: `power > 0 = start` ist zu vereinfacht
+   - Impact: Flackernde Sessions bei Power-Spikes
+   - Solution: Session-Engine aus Python portieren (M7) ← **DAS IST ALLES**
+- [ ] **M7**: REST Endpoint `/ows/iot/event` funktioniert
+  - [ ] Auth Tests: ✅ Alle Tests grün
+  - [ ] Manual Test: `curl -H "Authorization: Bearer xxx" -X POST ...` → 200 OK
+- [ ] **M7**: Events werden in `mqtt.event` persistiert
+  - [ ] Test: Event in DB sichtbar nach POST
+- [ ] **M8**: Python Bridge sendet Events an Odoo
+  - [ ] Integration Test: ✅ Event kommt in Odoo an
+  - [ ] Manual Test: Bridge läuft, Events in Odoo UI sichtbar
+- [ ] **M9**: Session-Detection läuft in Odoo (Dual-Threshold!)
+  - [ ] Unit Tests: ✅ State Machine korrekt
+  - [ ] Integration Test: ✅ Shelly → Session mit Debounce
+  - [ ] Manual Test: Maschine an/aus → Session startet/stoppt korrekt
+- [ ] **End-to-End**: Shelly → MQTT → Bridge → Odoo → Session sichtbar
+  - [ ] Test: Kompletter Flow funktioniert
+- [ ] **Dokumentation**: API, Setup, Troubleshooting komplett
+
+**Test-Driven Development:**
+- Jeder Milestone hat Tests BEVOR Code geschrieben wird
+- Keine manuelle UI-Klickerei zum Testen
+- `run-tests.sh` läuft jederzeit durch
+
+**Geschätzter Aufwand:** 4-6 Tage (bei fokussierter TDD-rt
+- [ ] Python Bridge sendet Events an Odoo (statt nur File)
+- [ ] Events werden in `mqtt.event` persistiert
+- [ ] Session-Detection läuft in Odoo (nicht nur Python)
+- [ ] Sessions werden automatisch bei Events aktualisiert
+- [ ] Tests laufen durch (Mock-basiert)
+- [ ] End-to-End Test: Shelly → MQTT → Bridge → Odoo → Session sichtbar
+- [ ] Dokumentation komplett (API, Setup, Troubleshooting)
+
+**Geschätzter Aufwand:** 4-6 Tage (bei fokussierter Arbeit)
+
+---
+
+## Changelog
+
+**2026-01-28 (Update 2):** Architektur vereinfacht - Odoo macht ALLES direkt
+- Phase 1: ✅ Komplett (Python Prototype)
+- Phase 2: 🚧 70% (Odoo Integration)
+- M7+M8 (REST/Bridge) GESTRICHEN → 2 Tage gespart!
+- Nur noch: M7 (Session-Engine portieren) + M8 (Tests reparieren)
+- Geschätzt: **2-3 Tage** statt 4-6!
