v0.3.0

[3dg1luk43]

[0.3.0] - 2024-12-31

This release marks a significant milestone for HA WashData, introducing intelligent profile-based cycle detection, a dedicated dashboard card, a completely rewritten configuration experience, and major improvements to cycle detection and time estimation.

Added

Custom Dashboard Card

Brand new in v0.3.0! A native-feeling Lovelace card designed specifically for washing machines, dryers, and dishwashers.

• Compact Tile Design: A sleek 1x6 row layout that fits perfectly with standard Home Assistant tile cards
• Dynamic Styling: Configure a custom Active Icon Color (e.g., Green or Blue) that lights up only when the appliance is running
• Program Display: Directly shows the detected or selected program (e.g., "Cotton 60°C") via the new Program Entity selector
• Smart Details: Toggle between "Time Remaining" (estimated) and "Progress %" as the primary status indicator
• Shadow DOM Implementation: Isolated styling to prevent conflicts with other Home Assistant components

Intelligent Profile Matching System

New cycle detection capabilities powered by NumPy:

• Profile-Based Detection: Learns appliance cycle patterns and uses shape correlation matching (MAE, correlation, peak similarity) to identify cycles in real-time
• Predictive Cycle Ending: Short-circuits the off_delay wait when a cycle matches with high confidence (>90%) and is >98% complete, reducing unnecessary wait times by up to 30 seconds
• Confidence Boosting: Adds a 20% score boost to profile matches with exceptionally high shape correlation (>0.85)
• Smart Time Prediction: Detects high-variance phases (e.g., heating) and "locks" the time estimate to prevent erratic jumps during unstable phases
• Cycle Extension Logic: Automatically extends cycles when profile matching indicates the appliance is still running, preventing premature cycle end detection
• Sub-State Reporting: Displays detailed cycle phases (e.g., "Running (Heating)", "Running (Cotton 60°C - 75%)") for better visibility
• Profile Persistence: Detected cycle profile names are now persisted and restored across Home Assistant restarts

Program Selection Entity

• New select.<name>_program_select entity for manual program overrides and system teaching
• Allows users to manually select the active program, helping the system learn and improve detection accuracy

Enhanced Configuration Wizard

The configuration flow has been rebuilt from the ground up to be friendlier and more organized:

• Two-Step Wizard:
  • Step 1 (Basic): Essential settings (Device Type, Power Sensor) and Notifications are now properly grouped here
  • Step 2 (Advanced): Accessible via the "Edit Advanced Settings" checkbox, containing fine-tuning options for power thresholds and timeouts
• Smart Suggestions: The "Apply Suggested Values" feature is now integrated into the Advanced step, helping you easily adopt values learned by the engine
• Reactive Synchronization: All profile/cycle modifications (create/delete/rename/label) trigger updates to keep the select entity in sync
• Precision UI: Replaced sliders with precise text-based box inputs for all configuration parameters
• Start Duration Threshold: Now configurable in advanced settings (previously hard-coded)

Advanced Cycle Detection

New logic to handle tricky appliances and prevent false detections:

• Start Debounce Filtering: Configurable debounce period to ignore brief power spikes before confirming cycle start
• Running Dead Zone: A new setting to ignore power dips during the first few seconds of a cycle (useful for machines that pause shortly after starting)
• End Repeat Count: Requires the "Off" condition to be met multiple times consecutively before finishing a cycle, preventing false cycle ends during long pauses/soaking
• Ghost Cycle Prevention: Added completion_min_seconds to filter out short "noise" cycles from being recorded as completed
• Device Type Configuration: Support for multiple appliance types (washing machine, dryer, dishwasher, coffee machine) with device-type-aware progress smoothing thresholds

Smoother Estimation Engine

• EMA Smoothing: Implemented Exponential Moving Average smoothing for progress and time-remaining sensors, eliminating the "jumping" behavior seen in previous versions
• Monotonic Progress: The progress percentage is now (almost) strictly enforced to never go backwards, ensuring a consistent countdown experience
• Smoothed Progress Initialization: _smoothed_progress is now properly initialized in __init__ to avoid runtime errors
• Smart Phase Detection: High-variance phases are detected and handled separately to prevent estimate instability

Pre-Completion Notifications

• Configurable alerts (notify_before_end_minutes) before estimated cycle end
• Helps users prepare for cycle completion without constant monitoring

Enhanced Testing Infrastructure

• Data-Driven Tests: New test suite tests/test_real_data.py replays real-world CSV/JSON cycle data
• Manager Tests: New tests/test_manager.py for comprehensive manager functionality testing
• Profile Store Tests: New tests/test_profile_store.py for storage and matching validation
• Restart Persistence Tests: New tests/repro/test_restart_persistence.py to verify state recovery
• Cycle Detector Improvements: Enhanced tests/test_cycle_detector.py with new test cases
• Conftest Utilities: Added tests/conftest.py with shared test fixtures

Development & DevOps

• GitHub Actions Workflows: Added hassfest.yml and validate.yml for automated validation
• Enhanced Mock Tooling: devtools/mqtt_mock_socket.py now supports:
  • --speedup X: Compresses time for faster testing
  • --variability Y: Adds realistic duration variance (default 0.15) for shape matching validation
  • --fault [DROPOUT|GLITCH|STUCK|INCOMPLETE]: Injects anomalies for resilience testing
• Secrets Template: Added devtools/secrets.py.template for easier development setup

Documentation & Assets

• Enhanced README: Completely rewritten with detailed configuration options, examples, and troubleshooting
• Updated IMPLEMENTATION.md: Reflects new architecture with NumPy-powered matching and profile persistence
• Improved TESTING.md: Enhanced verification guide with new test scenarios
• Screenshot Assets: Added screenshots in img/ directory:
  • integration-controls.png
  • integration-diagnostics.png
  • integration-profiles.png
  • integration-sensors.png
  • integration-settings.png
• GitHub Funding: Added .github/FUNDING.yml for sponsor support
