Hi All,

The device overview in HA is not using all of your screen estate, which makes it harder to read long entity names. thats why i (read AI) create this 1:2:1 responsive device overview via HACS.
Maybe its of use to anyone else :slight_smile:

HACS readme below:

Device Overview Responsive

Open this repository in HACS Open integrations in Home Assistant

Make Home Assistant device overview pages use the full browser width. Device Overview Responsive is a small HACS custom integration that registers a frontend module globally. It improves the built-in device detail pages under Settings by widening the narrow card columns on desktop screens.

It is built for Home Assistant setups with wide monitors, wall panels, large device pages, ESPHome devices, Z-Wave devices, Zigbee devices, diagnostic-heavy integrations, and dashboards where the default device overview leaves too much empty space.

Features

  • Detects Home Assistant device overview pages automatically.
  • Uses the available viewport width instead of keeping narrow default columns.
  • Applies a 2/8 - 4/8 - 2/8 distribution for three-column layouts.
  • Keeps the middle Controls/Sensors column wider on desktop screens.
  • Lets warning and repair cards span the full width.
  • Uses one column on narrow screens.
  • Re-applies after Home Assistant route changes and browser resizing.
  • Requires no dashboard YAML, Lovelace resources, entities, helpers, or automations.

Installation

HACS

Add this repository to HACS with My Home Assistant:

Add Device Overview Responsive to HACS

Or install manually:

  1. Open HACS in Home Assistant.
  2. Open the menu and choose Custom repositories.
  3. Add this repository URL:
https://github.com/matrover/ha-device-overview-responsive
  1. Select category Integration.
  2. Install Device Overview Responsive.
  3. Restart Home Assistant.
  4. Add Device Overview Responsive under Settings > Devices & services.
  5. Hard refresh the browser, clear frontend cache, or restart the Home Assistant companion app.

The integration serves and registers this frontend module automatically:

/device_overview_responsive/device-overview-responsive.js

The registered URL includes a version query string, for example:

/device_overview_responsive/device-overview-responsive.js?v=0.3.4

How It Works

When a Home Assistant device page opens, the module searches the rendered page for the built-in device overview card container. It then applies a responsive wrapping layout to that container.

On wide screens, three-column pages use weighted columns: the outer columns get 2 parts each and the middle column gets 4 parts. On smaller screens, the columns wrap naturally, and below the mobile breakpoint they stack into one column.

Supported Use Cases

  • Device overview pages on wide desktop monitors.
  • Device pages with Controls, Sensors, Activity, Automations, Scenes, Scripts, or Configuration cards.
  • Device pages with warning or repair cards above the main content.
  • ESPHome, Z-Wave, Zigbee, MQTT, UniFi, Shelly, Tuya, and other integration device pages.
  • Home Assistant instances where the default device page wastes horizontal space.

Limitations

  • This is a frontend layout integration. It does not create entities, helpers, automations, or dashboards.
  • It only targets built-in Home Assistant device overview pages under /config/devices/device/....
  • Home Assistant frontend internals can change between releases, so layout detection may need updates after major frontend changes.
  • HACS, reverse proxies, Cloudflare, browsers, and companion apps may cache old frontend modules until a hard refresh or app restart.

Troubleshooting

  • Layout unchanged: confirm the integration is installed and added under Settings > Devices & services.
  • Old layout still visible: hard refresh the browser or restart the Home Assistant companion app.
  • Still seeing an old version: check that the loaded module URL contains the current ?v= version.
  • Columns look wrong after resizing: wait a second or refresh; the module reapplies after route changes and resize events.
  • A column disappears or clips: update to the latest release and hard refresh the browser.

Update, made the max widht of the columns configurable. via settings:

Configuration

Open Settings > Devices & services > Device Overview Responsive > Configure.

Available option:

  • Maximum total column width: caps the complete column container width in pixels.

Use 0 to keep the current unlimited responsive behavior. This is the default.

After changing this option:

  1. Save the integration configuration.
  2. Hard refresh the browser tab or restart the Home Assistant companion app.

You do not need to restart Home Assistant after changing only this option. Installing or updating the integration through HACS still requires a Home Assistant restart. On narrow mobile screens, this limit is ignored so cards stay readable and inside the viewport.
