Entity Duplicates Manager

Entity Duplicates Manager is a Home Assistant integration designed to identify, manage, and clean up duplicate entities in your Home Assistant instance. It helps keep your entity registry clean by finding entities with suffix patterns like _2, _3 that often occur when devices are re-added or integrations are reconfigured.

Features

• Scan for Duplicates: Automatically scans your entity registry for potential duplicates based on configurable naming patterns.
• Interactive Card: A custom Lovelace card to view results, rename entities ("Fix"), or delete them directly from the dashboard.
• Configurable Filters:
  • Suffix Depth: Control how deep to look for suffixes (e.g., _2 to _5).
  • Exclude Patterns: Prevent specific entities or domains (like sensor.uptime*) from being flagged.
• Safe Operations:
  • Fix: Renames the duplicate entity to a desired ID (e.g., merging it back to the original name).
  • Delete: Removes the entity from the registry.
