Devices

The device catalog at /devicer/devices.

Overview

The page — Mobile Devices in the navigation, headed Mobile Device Management — lists every mobile device connected to the farm. Filtering, sorting, and paging are performed by the backend, so the list stays usable on large fleets. The list refreshes every five seconds while the browser tab is visible, and pauses while a device is being connected.

The current filter state is written to the URL, so a filtered view can be shared as a link.

Status Tabs

Tab	Shows
All Devices	The whole fleet
Available	Devices that are online and free
In Use	Devices that are busy or reserved
Automation	Devices running an automation session
Offline	Devices that are not connected

Each tab carries a count badge taken from the backend fleet statistics.

Search, Filters, and Sort

Search matches as you type, with a short debounce.

The filter menu offers:

Group	Options
Status	Online, Busy, Offline (available on the All Devices tab only)
Device Type	Real, Emulator / Sim
Platform	iOS, Android
Version	Every OS version present in the fleet

Status, type, platform, and version are all multi-select. Selections appear as removable chips under the toolbar, alongside a Clear all control.

Sort offers Availability (the default), Name (A-Z), and Name (Z-A).

View Modes

Four view modes sit at the right of the toolbar.

Mode	Description
Compact	Dense card grid, the default
Grid	Larger detail cards
List	Table rows
Tree	Platform, model, and version drill-down

Tree View

Tree view replaces the flat grid with cascading columns: Platform, then Model for that platform, then Version for that model. Each entry shows a count, and each column scrolls independently so the page height stays fixed no matter how large the fleet is.

Choosing a platform reveals the model column, and choosing a model reveals the version column and the matching device cards below. A breadcrumb under the columns tracks the current selection, and Clear selection resets it.

The active status tab scopes both the counts and the device cards, so the tree agrees with the tab above it. The search box still applies; the filter and sort menus are hidden in tree view because the columns take their place.

Device Cards

Each card shows:

• Device name, or its alias when one has been set.
• Platform icon and OS version.
• A type badge: Real, Emu for Android emulators, or Sim for iOS simulators.
• Hardware summary — chipset or CPU architecture and installed RAM, when reported.
• Current status, and who is using the device when it is busy.
• A favorite star.

Hovering a card shows a tooltip with the original device name when an alias is set, the full device type, the RAM and chipset, the current user, and when the device was last used.

Device Types

The backend uses a single Emulator value for both Android emulators and iOS simulators. The interface splits the label by platform, so iOS entries read Simulator and everything else reads Emulator.

iOS simulators accept a .app bundle or a zipped .app rather than an .ipa; real iOS devices accept an .ipa.

Renaming a Device

Administrators, account owners, and managers can give a device an alias. Select the pencil next to the name, type the new name, and confirm. The original device name is preserved and shown in the card tooltip.

Starting a Session

Select Start on an available device. The session is created and you are taken to /devicer/live-testing/{sessionId}, where a loading screen reports the provisioning progress until the stream is ready.

If the device cannot be used, the page explains why instead of failing silently:

Message	Meaning
Device is in maintenance	The device is in maintenance mode
Node is draining	The node hosting the device is being drained
Hub is in maintenance	The hub serving the device is in maintenance mode
Device unavailable for this session type	The device is not accepting this kind of session right now
Hub not connected	The hub is not currently connected
Unable to start session	Any other failure, with the reason returned by the service

Maintenance and draining are shown as warnings because they are expected to clear on their own.

Other Card Actions

Action	Available when	Description
Reserve	The device is online and free, with session permission	Opens the reservation form for that device
View	The device has a session you can view	Opens the running session
Open	The session is still starting	Opens the session that is being provisioned
End	You own the session, or you are an admin or manager	Ends the running session
Favorite	Always	Stars the device

See Reservations for the full scheduling flow, and Device Control for what happens once a session is open.
