wtf is ha-area-manager?

Area Manager is a Home Assistant custom integration that adds a sidebar panel for finding devices and entities that have no area assigned, then quickly assigning, ignoring, or deleting them, all without hunting through several settings pages. The panel has a switcher at the top that toggles between devices and device-less entities such as automations, scripts, scenes, and helper entities like input booleans, input numbers, counters, and timers. Both views share the same tabs, filtering, and bulk actions. The main list shows everything without an area assigned yet. You can assign an area to a single row from a dropdown, or select multiple rows with checkboxes and assign or ignore them all at once, with your selection kept even as you keep filtering. A separate Assigned tab lets you review devices and entities that already have an area, correct mistakes, or unassign them back to Without Area. Columns can be sorted by clicking their headers, and a filter bar lets you search by name, manufacturer, model, or entity ID, or filter by manufacturer or integration. Clicking any row opens a detail popup showing manufacturer, model, integration, current area, when it was added, and when it was last seen. From there you can rename or delete a device, though rename and delete only apply to devices, since a device-less entity's configuration lives in YAML or in whatever integration created it. You can also mark devices or entities to ignore if they intentionally have no area, and restore them later. Ignored items are stored in Home Assistant's storage, so they survive restarts. The interface is available in German and English, following your Home Assistant language setting. To use this you need Home Assistant 2024.1 or newer and HACS installed. Installation is one click through HACS using the provided badge, or manual by adding the custom repository, downloading the integration, and restarting Home Assistant. After restart, add the Area Manager integration through Settings, and it appears in the sidebar with no further configuration needed.
