From c1df940daf7a8fd446178e4c481cb094a0801dcd Mon Sep 17 00:00:00 2001 From: "matthias.lotz" Date: Wed, 4 Feb 2026 16:46:13 +0100 Subject: [PATCH] feat(mqtt): IoT Bridge Phase 1.3 - Session Detection mit Integration Tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - IoT Bridge Grundstruktur (config, logging, MQTT client) - Session Detector mit 5-State-Machine und Aggregation - Heartbeat Events alle 10s (configurable) - Aggregation: interval_working_s, interval_standby_s, avg_power_w - Unit Tests: 9/9 passed (session_detector) - Integration Tests: 7/7 passed (mit Shelly Simulator) - Lokaler Mosquitto Container Support (docker-compose.dev.yaml) - --config CLI argument für main.py - Auto-Reconnect und TLS Support Test Coverage: - Session Start/End Detection - State Transitions (IDLE→STANDBY→WORKING) - Heartbeat Emission mit Aggregation - Multi-Device Parallel Sessions - Timeout Detection (20s) Phase 1.3 ✅ COMPLETE --- open_workshop_mqtt/IMPLEMENTATION_PLAN.md | 262 ++++++++++ open_workshop_mqtt/iot_bridge/.gitignore | 48 ++ open_workshop_mqtt/iot_bridge/Dockerfile | 26 + open_workshop_mqtt/iot_bridge/README.md | 392 +++++++++++++++ open_workshop_mqtt/iot_bridge/config.py | 90 ++++ open_workshop_mqtt/iot_bridge/config.yaml | 36 ++ .../iot_bridge/config.yaml.example | 35 ++ open_workshop_mqtt/iot_bridge/logger_setup.py | 35 ++ open_workshop_mqtt/iot_bridge/main.py | 329 +++++++++++++ open_workshop_mqtt/iot_bridge/mqtt_client.py | 144 ++++++ open_workshop_mqtt/iot_bridge/odoo_client.py | 65 +++ .../iot_bridge/requirements.txt | 33 ++ .../iot_bridge/session_detector.py | 305 ++++++++++++ .../iot_bridge/shelly_parser.py | 79 +++ .../iot_bridge/tests/__init__.py | 1 + .../iot_bridge/tests/integration/__init__.py | 1 + .../integration/test_bridge_integration.py | 459 ++++++++++++++++++ .../iot_bridge/tests/tools/__init__.py | 1 + .../tests/tools/shelly_simulator.py | 190 ++++++++ .../iot_bridge/tests/unit/__init__.py | 1 + .../tests/unit/test_session_detector.py | 233 +++++++++ 21 files changed, 2765 insertions(+) create mode 100644 open_workshop_mqtt/IMPLEMENTATION_PLAN.md create mode 100644 open_workshop_mqtt/iot_bridge/.gitignore create mode 100644 open_workshop_mqtt/iot_bridge/Dockerfile create mode 100644 open_workshop_mqtt/iot_bridge/README.md create mode 100644 open_workshop_mqtt/iot_bridge/config.py create mode 100644 open_workshop_mqtt/iot_bridge/config.yaml create mode 100644 open_workshop_mqtt/iot_bridge/config.yaml.example create mode 100644 open_workshop_mqtt/iot_bridge/logger_setup.py create mode 100644 open_workshop_mqtt/iot_bridge/main.py create mode 100644 open_workshop_mqtt/iot_bridge/mqtt_client.py create mode 100644 open_workshop_mqtt/iot_bridge/odoo_client.py create mode 100644 open_workshop_mqtt/iot_bridge/requirements.txt create mode 100644 open_workshop_mqtt/iot_bridge/session_detector.py create mode 100644 open_workshop_mqtt/iot_bridge/shelly_parser.py create mode 100644 open_workshop_mqtt/iot_bridge/tests/__init__.py create mode 100644 open_workshop_mqtt/iot_bridge/tests/integration/__init__.py create mode 100644 open_workshop_mqtt/iot_bridge/tests/integration/test_bridge_integration.py create mode 100644 open_workshop_mqtt/iot_bridge/tests/tools/__init__.py create mode 100644 open_workshop_mqtt/iot_bridge/tests/tools/shelly_simulator.py create mode 100644 open_workshop_mqtt/iot_bridge/tests/unit/__init__.py create mode 100644 open_workshop_mqtt/iot_bridge/tests/unit/test_session_detector.py diff --git a/open_workshop_mqtt/IMPLEMENTATION_PLAN.md b/open_workshop_mqtt/IMPLEMENTATION_PLAN.md new file mode 100644 index 0000000..f319d30 --- /dev/null +++ b/open_workshop_mqtt/IMPLEMENTATION_PLAN.md @@ -0,0 +1,262 @@ +# Implementation Plan: IoT Bridge & Odoo Integration + +**Ziel:** Sidecar-Container-Architektur mit periodischer Session-Aggregation +**Stand:** 03.02.2026 +**Strategie:** Bridge zuerst (standalone testbar), dann Odoo API, dann Integration + +--- + +## 📦 Bestandsaufnahme + +### Vorhanden (wiederverwendbar) +- ✅ `python_prototype/` -
