Users & Devices
Preview feature
The Users & Devices tab requires the LCARdS HA integration (v2026.3.0+) with the scoped_storage capability. If the integration is absent or on an older version, the tab is hidden.
The Users & Devices tab in the LCARdS Config Panel is the central place to view and manage the devices and users that have stored per-device or per-user setting overrides.
It has three sections. Non-admin users see only Current Session. HA admins see all three.
Current Session
Shows the identity of the current browser session — this is your device record as seen by LCARdS.
| Field | Description |
|---|---|
| Device name | Human-readable label for this browser. Editable by any user — click the edit icon, type a new name, and save. Also settable via the URL parameter ?lcards_device=My%20Tablet on first visit. |
| Device ID | Stable UUID stored in this browser's localStorage. Persists across page reloads and HA logins from the same browser profile. |
| Last seen | Timestamp of this device's last heartbeat to the backend. |
| User agent | Browser/OS string recorded at last registration. |
Setting a device name is optional but makes it much easier to identify sessions in the Devices list and when using targeted HA services.
Users (admin only)
Lists every HA user who has at least one stored per-user override. For each entry you can see:
- The HA display name (resolved from the HA auth list)
- The opaque HA user ID
- A Clear overrides action — removes all per-user scoped settings for that user, reverting them to Device → Global fallback
Clearing overrides does not affect the user's device records or any global settings.
Devices (admin only)
Lists every device that has ever registered a heartbeat with the LCARdS backend. For each device:
| Column | Description |
|---|---|
| Name | Display name — click the edit (pencil) icon to rename inline |
| Last seen | ISO timestamp of the last heartbeat |
| Device ID | Stable UUID for targeting services |
| Delete | Removes the entire device record from the backend (requires confirmation). Any scoped overrides stored for this device are also deleted. |
Deleting a device does not prevent it from re-registering — if the browser visits the dashboard again it will create a new record with the same UUID.
How scoped settings work
LCARdS settings (currently: sound scheme, per-event sound overrides) are resolved in this order, using the first non-null value found:
Device scope → User scope → Global scope → HA helper fallback- Device overrides apply to any HA user logged in on that specific browser.
- User overrides apply to a specific HA user regardless of which device they use.
- Global is the installation-wide default, shared by everyone.
Per-user and per-device overrides are configured in the individual feature tabs (e.g. Sound → Per-User / Per-Device Overrides section). The Users & Devices tab is the admin view for managing existing records — it does not expose raw setting values.
