v0.4.2

[0.4.2] - 2026-02-11

✨ Features

• Advanced Parameter Auto-Suggestion:
  • New SuggestionEngine that analyzes your appliance's actual power traces to recommend optimal settings.
  • Automatically suggests values for start_threshold_w, off_delay, watchdog_interval, and more based on observed behavior.
  • Periodic background optimization to keep settings tuned as your appliance ages or use patterns change.
• Electric Vehicle (EV) Support:
  • Added new "Electric Vehicle" device type with optimized defaults.
  • New icons and phase heuristics ("Charging", "Maintenance").
• Divergence Detection:
  • Improved matching logic to detect when a cycle starts diverging from its matched profile.
  • Automatically reverts to "Detecting..." if confidence drops significantly below the cycle's peak (default 40% drop).
• Card Animation:
  • Added native spinning animation to the dashboard card icon when the appliance is running.
• Configurable Stability Thresholds:
  • Added DEFAULT_MATCH_REVERT_RATIO and DEFAULT_DEFER_FINISH_CONFIDENCE to const.py for easier fine-tuning.
• Profile-Aware Watchdog:
  • The watchdog now uses "look-ahead" logic from the matched profile to prevent premature cycle termination during long legitimate pauses (e.g., dishwasher drying).
  • Automatically extends silence timeouts if the cycle is within its expected profile duration.
• Zombie Protection:
  • Implemented a hard "Zombie Killer" limit that force-ends cycles exceeding 200% of their expected profile duration (min 2 hours).
• Stuck Power Prevention:
  • Automatically resets the power sensor to 0W when a cycle is forced to end by the watchdog or manual stop, fixing issues where the entity remained at a high value.
• Zero-Latency Low-Power Processing:
  • Power updates below min_power now bypass all debouncing, smoothing, and sampling interval filters, ensuring immediate cycle-end detection.
• Program Detection Stability:
  • Implemented temporal persistence for profile matching: requires 3 consecutive consistent matches before switching from "detecting..." to a profile, or before unmatching a profile.
  • Added a minimum confidence gap for mid-cycle profile switching to prevent "flapping" between similar programs.
• Total Duration Sensor:
  • New total_duration sensor providing the predicted total cycle time (Elapsed + Remaining).
  • Designed specifically to support full progress bars in timer-bar-card.
  • Dynamically updates as estimates are refined.
    -Languages
  • Added many new languages

🛠️ Improvements

• Manual Recording Robustness:
  • Increased gap threshold to 6 hours to support very long Eco cycles with multi-hour silent phases.
  • Unified automatic trimming threshold to 1.0W across the integration.
• Clean Card UI:
  • Removed redundant "off" label from completion details when the appliance is inactive.
• Zigbee2MQTT Guidance:
  • Added optimized configuration tips for Z2M smart plug users in README.

🐛 Bug Fixes

• Profile Alignment Error (#112):
  • Fixed a critical TypeError: 'float' object is not subscriptable in the profile matching pipeline.
• Terminal State Persistence:
  • Fixed a bug where finished and interrupted states were not resetting to off after the intended 30-minute timeout.
• Profile Shrinking:
  • Fixed an issue where maintenance tasks would aggressively trim trailing silence from completed cycles, causing profiles to shorten over time.
• Termination Hangs:
  • Restricted "Deferred Finish" logic to require high confidence (> 0.55) or a verified pause, preventing cycles from hanging on mismatched long profiles.
• Long Drying Phase Support:
  • Fixed an issue where dishwashers with multi-hour silent drying phases were being split into multiple cycles by the watchdog.
  • Recognizes "Verified Pause" from profile envelope to extend silence timeouts.
• Test Stability:
  • Resolved several TypeError issues in the test suite and improved mocking reliability for sensors and configs.
