# Game Bar

An overlay for [DankMaterialShell](https://danklinux.com/docs/dankmaterialshell/plugins-overview).

## Widgets

| Widget | Contents |
|---|---|
| **Audio** | Master output volume + mute, output device switching, microphone volume + mute, input device switching |
| **Apps** | Per-application volume sliders with individual mute, app icon and what is playing |
| **Media** | Now playing with album art, seek bar, previous/play/next, and a chip per MPRIS source to switch between players |
| **Performance** | CPU (usage, temperature), memory (used / total), network (rx/tx), disk (root usage, read/write) |
| **Home** | Home Assistant entities you pick: lights (toggle + brightness), numbers (slider over the entity's own min/max/step), switches/fans, media players (volume, mute, play/pause), covers, scenes and scripts, plus read-only sensors |

## Home Assistant

Settings → Plugins → Game Bar:

1. **Home Assistant URL**, e.g. `http://homeassistant.local:8123`
2. **Long-lived access token** — HA profile page → *Security* → *Create token*.
   It is stored in `plugin_settings.json`, which is world-readable by default
   (`chmod 600` it if that matters to you).
3. **Refresh**, then tick the entities you want in the Home widget.

State is polled (default every 5 s) only while the Home widget is open. The token is handed to
`curl` through the process environment, so it never shows up in the process list.

If a refresh fails, `dms ipc call gameBar homeStatus` shows what the plugin actually sent and got
back. A `401` means Home Assistant rejected the token; compare with

```bash
curl -H "Authorization: Bearer <token>" https://your-ha/api/
```
Note that editing `plugin_settings.json` by hand does not reach a running shell.

## Settings

Settings → Plugins → Game Bar (gear icon):

- **Home Assistant** — URL, access token, refresh interval, and the entity picker.
- **Reset widget positions** — back to the default arrangement on every monitor.
