Monitor device health

Check which check in scanners are online, offline, or low on battery during an event, and ping a device to get a staffer's attention.

The Devices page for an event shows the status of every scanner signed in to it — whether each device is online, how much battery it has, and how recently it last synced. Use it to spot a scanner that has dropped offline or is running low on power before it becomes a problem at the door.

Requirements: An event with at least one device signed in. See Install the check in app.

Two Devices pages

There are two, and they show different things:

  • Inside an event (Onsite → Devices) — only the scanners whose staff member is assigned to that event. This is the one to watch during a show, and the one this article covers.
  • Check In → Devices in the main sidebar — every device on your account. Use this one to see all your devices, to manage your plan’s device limit, or when a device is missing from the event list.

Open the Devices page

  1. Open the event.

  2. In the sidebar, under Onsite, click Devices.

The page lists every device whose staff member is assigned to this event, with summary tiles across the top.

Read the status tiles

The tiles at the top of the page count devices by health:

  • Online — devices currently connected.
  • Offline — devices that have lost their connection.
  • Low battery — devices reporting under 20% battery.

Click the icon next to a count to open the list of just those devices — for example, to see every scanner that is low on battery so you can have them brought back to charge.

Read the device table

Each row is one scanner. The columns report the device’s name, the staff member signed in, its station, whether it’s online, when it last reported in, when it last synced, and its battery level. The scan counts (successful, unsuccessful, total) link to the matching scans, so you can click a count to see exactly which scans that device recorded.

Ping a device

Use Ping to get the attention of whoever is holding a scanner — for example, to ask them to charge it or move stations.

  1. Find the device in the list.

  2. Click Ping.

The device shows an alert. Pinging needs the device to be online; an offline device receives the ping the next time it reconnects.

Reassign a device

Use Edit to rename a device or move it to a different station.

  1. Find the device in the list.

  2. Click Edit.

  3. Change the Name, or pick a different station, and save.

FAQ

A device shows offline but the staffer says it’s working

Offline means the device hasn’t reported in to Guest Manager recently, usually because of weak Wi-Fi or cellular signal. The Check In app keeps scanning offline and uploads its scans once it reconnects, so an offline device can still be checking attendees in. Move it to better signal to bring its status and scan counts up to date.

Why does the battery level look stale?

The battery level comes from the device’s last report, shown in the last reported column. If a device has been offline, its battery reading is from the last time it connected, not the current moment.

A device is missing from the list

The event’s Devices page only lists scanners whose staff member is assigned to that event, so a device you own can be missing from it and still be perfectly fine.

To see every device on your account, go to Check In → Devices in the main sidebar. If the device is there but not on the event page, assign its staff member to the event and make sure they are signed in on the device.

I can’t find all my devices, or the count looks wrong

Use Check In → Devices — the event page is filtered by event roster and will not show everything.

On that page, check the Filter button as well. Archived at defaults to Unarchived, so archived devices are hidden and the count under the table (“Showing 1 to 5 of 5 entries, filtered from 17 total entries”) can be far smaller than your real device count. Clear that filter to see every device.

See Device management and limits for what counts toward your plan’s limit.
