HA Optimizer is a custom integration for Home Assistant, the popular open-source home automation platform. Over time, a Home Assistant setup accumulates clutter: devices get removed but their software records (called entities) linger, automations break silently, and the internal database grows large because some sensors write updates too frequently. HA Optimizer automatically scans for all of these problems and gives you a safe way to clean them up. The main scanner categorizes every lingering entity by risk level so you know what is safe to remove. Rather than deleting things immediately, it uses a soft-delete approach: items are disabled and moved to a trash bin first, where they can be restored if needed, and only permanently removed after a configurable number of days. It also analyzes the recorder database (which stores historical sensor data) to find which entities write the most and whether those writes are useful. A dashboard analyzer checks UI panels for cards referencing entities that no longer exist. An automation analyzer scans for automations that act on deleted devices. An anomaly detection feature compares today's system behavior against a rolling 30-day history to flag unusual spikes in database writes or automation activity. A built-in add-on manager shows all installed Home Assistant add-ons with live CPU and RAM usage, and real-time system resource gauges appear at the top of every tab. The interface supports 12 languages and 11 visual themes. It installs via HACS (the Home Assistant Community Store) and requires Home Assistant 2023.1 or newer.
