# The device record: tabs and cards of the machine

The **Devices** area lists the machines behind the displays, including those with no display attached right now. Every piece of information has its tab. Look up the tab instead of searching the whole record.

> **Type:** reference
> **For:** anyone looking after a device who wants to know where a piece of information is
> **Prerequisite:** an account in your organization. Commands need the Manager or Owner role, the **Lifecycle** tab the Owner role.
> **Where in the portal:** **Devices** › device

## The list under Devices

The search field **Name, model, serial number or display …** searches all four fields. Next to it are two filters: **Displays** with **All devices**, **With a display**, and **Without a display**, and **Display software version** with **All versions** and **Display software outdated**. The second shows every device whose display software does not run the version that its channel has released. There is no filter for the status, because every device in the list is paired.

| Column | What it says |
|---|---|
| **Device** | the name of the device. By default it is **Player** followed by the last four characters of the serial number, for example **Player 7AA9**. |
| **Build** | **Raspberry Pi 5**, **Raspberry Pi 4**, **Linux machine**, or **Web display**, for a host app its name, for example **Fire TV app**. As long as nothing is reported, it says **not reported yet**. |
| **State** | **paired**. If a device has left your organization, for example after **Re-pair** or **Report as lost**, it no longer appears in the list. |
| **System** | what the display software runs on. For a player, it says **SzeneraOS** with version and channel, for example **SzeneraOS 0.3.35** and **Stable**, and **Browser** for every device without SzeneraOS. Below it is the version of the display software, for example **Display software 0.4.11**, and **outdated** if it does not match the version of its channel. As long as nothing is reported, it says **not reported yet**. |
| **Displays** | the displays on this machine. If none is attached, it says **no display**. |
| **Last reported** | time of the last report, otherwise **never reported** |

If nothing is paired yet, it says **No device paired yet.** If no device matches the selection, it says **No device matches this selection.**

## The header of the record

Above the tabs are the device name, then the model, serial number, and **known since …**, and next to them two badges: the state and the build. For a host app, the name of the app appears in place of the build, for example **Fire TV app**. Owners and Managers can change the name in the device record. When the device leaves your organization, it falls back to the factory name.

## The seven tabs

| Tab | What it says |
|---|---|
| **Overview** | how the machine is doing: state, key figures, its displays, connection, system, abilities, latest events |
| **Remote service** | the commands to the machine, running orders, the full operations log, and the history of the commands |
| **Hardware** | what the machine measures about itself: processor, memory, disk, network, connected TV or monitor, system state, history |
| **System** | software versions and the content that is on the device |
| **Offline stock** | how much of the program’s media actually sits on the disk |
| **Location** | the position that the device determined from its radio environment |
| **Lifecycle** | the four actions with which the device leaves your organization |

### Overview

| Card | Content |
|---|---|
| **State of the device** | **Reporting in**, **Delayed**, **No connection**, or **Never reported**, plus **One screen is showing content** or **N of M screens are showing content** or **No screen attached**, **Running for …** and, where applicable, **Throttling** and the temperature |
| Key figures | the same statements as a number, colored by their limit |
| **Displays on this device** | each connected TV or monitor with **Display 1**, **Display 2** …, connector and cable state (**connected**, **No cable**, **connector gone**), plus **Add display**. If none is attached: **No display is attached to this device.** |
| **Connection** | **Wi-Fi**, **Network**, **Response time**, **IP address**, **Last reported**, and **Realtime channel** (**connected** / **disconnected**) |
| **System & runtime** | the parts of the software that the device has, with the same rows as the **Software** card on the **System** tab, plus **System image** while a switch is running, **Running for**, and **Throttling**. What the parts mean is explained under [Key terms](/docs/getting-started/key-terms#what-runs-on-a-device). |
| **What this device can do** | **System updates** and **Multiple outputs** as **available** or **not available**. If something is missing, the reason appears next to it, for example **This device drives one screen**. |
| **Latest events** | an excerpt of the operations log. **Full log** opens the complete log. |

### Remote service

Four blocks one below the other: **Device remote service** with the commands, **Orders in progress**, the **Operations log** in full length, and **Commands on this machine**. The last table lists **all** orders to this device, including those to its displays. The **Applies to** column names whom an order affected. The commands themselves are described in [Maintain a device remotely](/docs/devices/maintain-device-remotely).

### Hardware

| Card | Content |
|---|---|
| **Processor & heat** | **Processor**, **Cores**, **Load average 1 / 5 / 15 min**, **Temperature** with **Peak**, **Frequency**, **Core voltage**, **Throttling**, **Image slot** |
| **Memory** | **Installed**, **Used**, **Free**, **Display process** |
| **Storage** | **System** and **Content** separately, each with **Total size**, the used share, and **free**, plus **Health** |
| **Network** | **Connection** (**Wi-Fi** or **Wired**, with the name of the interface behind it), **Network**, **Signal**, **Band**, **Frequency**, **Link rate**, **IP address**, **MAC**, **Gateway**, **Cloud reachable**, **Response time**, **Remote access** |
| **Screen** | **Connector**, **Manufacturer**, **Model**, **Serial number**, **Diagonal**, **Video mode**, and whether it is **connected** or reports **no signal** |
| **System state** | the running image slot, **trial boot**, and **Display access valid until** |
| **History** | **Temperature**, **Wi-Fi signal**, **Response time**, **Free storage**, **Processor load**, and **Memory** over **24 hrs**, **7 days**, or **90 days**. Conspicuous series carry the mark **notable**. |

Periods without a report stay empty in the history and are not drawn as zero.

### System

The **Software** card first lists the parts of the software on the device. A row for a part that the device does not have is omitted.

| Row | What it says |
|---|---|
| **Display software** | the version, next to it the identifier of its build, and below it where it comes from: **bundle from …** on a player, **from the cloud** on a host app and on a web display |
| **Host** | on a player, the **Kiosk session** and next to it whether it is currently **rendering**. On a host app, its name with version appears, for example **Fire TV app 1.0.0**, and below it what it can do, for example **Screenshot, restart only with system permission**. If the app reports whether it starts by itself after power-on, **Autostart** or **Autostart blocked** appears in addition. On a web display with a display extension, it says **Display extension** with the version and below it **Screenshot**. |
| **Remote maintenance** | only on a player: the version and, where the device reports it, the identifier of its build |
| **SzeneraOS** | only on a player: the version, for example **0.3.35** |
| **Channel** | only on a player: **Stable**, **Beta**, or **Preview**. Display software, remote maintenance, and SzeneraOS follow it. We set it for each device. If the device has not yet adopted a new channel, that appears below. |

Next to the versions of display software, remote maintenance, and SzeneraOS is their state:

| State | Meaning |
|---|---|
| **up to date** | The device runs the version that its channel has released. |
| **updating** | The device has accepted the new version and is switching right now. Below it appears what is released in the channel. |
| **rolled back** | The device tried the new version and returned to the previous one because it did not report as healthy. Below it are both versions and the reason, for example **The display software stopped with an error while starting.** |
| **outdated** | The device still runs an older version, for example **This display software still shows 0.4.11. The new version arrives within the next hour.** |

If no state is shown, the channel has not yet released a version for this part, or the device does not report the identifier of its build. You do not have to trigger the switch, because it comes by itself ([How does a player update itself?](/docs/devices/about-player-updates)).

On a web display, the rows are followed by **This device is a web display. It has no remote maintenance and no SzeneraOS.**

After that come **System image** with **Last changed**, **Kernel**, **Boot slot**, **Last frame**, **Clock** (**in sync** or **not synchronized**), and **Time zone**. A web display has no system image, so **System image** and **Last changed** are omitted there. Below it is **Content on the device** with its state (**current** or **stale**), the **Revision** with the note **checked** and a time, and the table of app bundles: **App**, **Version**, **Size**, **State** (**current**, **Update** with the target version, **unused**), and **Last loaded**.

### Offline stock

The **Offline stock** card shows **Present**, **Used** with the limit, **Required**, and **Overflow**, and below them for each media item **Rendition**, **State** (**present** / **missing**), **Size**, and **Age**. If something is missing, **N items missing** appears at the top, otherwise **complete**. The app bundles are deliberately not listed here but on the **System** tab, because they age by a rule of their own.

### Location

The **Measured position** card shows **Resolved location**, **Address**, **Coordinates**, **Accuracy**, and **Last determined**, plus **Determined via**, either **via the radio environment** or **via the IP address**. The **Determine again** button starts a new measurement. This is a measured value, not a maintained location: You change that one on the display under **Settings**.

### Lifecycle

The **Lifecycle** card has four rows, each with its consequence in one sentence and a button of its own: **Re-pair …**, **Factory state …**, **Remove …**, and **Report lost …**. For a web display, only **Re-pair …** and **Remove …** appear. What each action does is explained under [Device lifecycle](/docs/devices/device-lifecycle).

## With a web display

Behind a web display is a browser and not a machine that can be measured. The display software runs there as on any device, and only remote maintenance and SzeneraOS are missing. Instead of processor and network card, there is the short **Browser** card with **Browser**, **Operating system**, **Window size**, and **Display extension** (**installed** or **not installed**). Below it, **Browser tab** with **rendering** or **in the background** appears as soon as the display software reports its tab. It does that without the extension too.

A host app such as the **Fire TV app** on a Fire TV or Android device shows the same **Browser** card. In place of the extension, it shows the **Host** with the name and version of the app, for example **Fire TV app 1.0.0**. There is no extension for these devices. What the app can do depends on the platform and version, so when something goes wrong, the version is the first thing support asks about. A Samsung or LG panel opens the display software in its browser today and is therefore a web display like any other.

## Why some things appear only here

History, app bundles, offline stock, location, and the full operations log belong to the machine and therefore appear once in the device record, instead of once more on every display.
