# Lost Alert

## What is a <mark style="color:red;">"Lost"</mark> alert for?

The **"Material Lost"** alert is triggered when a piece of equipment **has not been detected for an abnormal length of time**. It lets you quickly identify potentially lost or stolen materials and act before they become unrecoverable.

It lets you:

* **Detect equipment absent from its monitoring zone**.

The alert is triggered when a material **equipped with a GPS tracker** has not been detected for a **defined length of time**. Once active, it lets you:

* **Receive an automatic alert** when a piece of equipment disappears from the tracking system.

***

## Elements subject to "Item lost" alerts

### Materials & Storage zones

* All connected materials or storage zones **tracked with a sensor or GPS tracker**.

{% hint style="success" %}
You have the option to **find the material again via a** [<mark style="color:green;">**Material Found**</mark>](#user-content-fn-1)[^1] alert as soon as it is detected again.
{% endhint %}

{% endstep %}

{% step %}

#### Configure the alert

Enter the **alert name**: give it a clear title (e.g. *Power tools lost 30d*).

Choose the elements this alert applies to:

* **Element type**:
  * Materials
  * Storage zones
* **Relevant material or zone type(s)**: select the relevant material or zone types (e.g. *Jackhammer*, *Aerial platform*).

Set the number of days to be considered lost, i.e. the number of days without a detection of your element to trigger the alert.

{% endstep %}

{% step %}

#### Staff notification

Set up the person or people to notify as soon as an alert is triggered.

* **Notify staff**: choose specific users to alert.
* **Notify teams**: you can also notify an entire team.

If no staff member is entered, the alert will simply be recorded without any notification.

You can also add several notification levels:

* when the alert is triggered,
* or at different deadlines (e.g. X days after the element switches to "lost").

<div data-with-frame="true"><figure><img src="https://610225865-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FZXGOc01SlXkWj62sepZX%2Fuploads%2F0SamNgU1G97ek3ns8HVn%2FCapture%20d%E2%80%99e%CC%81cran%202026-09-13%20a%CC%80%2020.32.49.png?alt=media&amp;token=db12ec48-bb07-40cb-8519-ea8ce3aa488f" alt=""><figcaption></figcaption></figure></div>

You can enable the ***"Add an 'Item found' notification"*** option to receive a notification when one of the elements that switched to "**lost**" status is detected again.

<div data-with-frame="true"><figure><img src="https://610225865-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FZXGOc01SlXkWj62sepZX%2Fuploads%2FWAj1n0Bh10Tli0QXtXzR%2FCapture%20d%E2%80%99e%CC%81cran%202026-09-13%20a%CC%80%2020.32.54.png?alt=media&amp;token=cdabeb10-28dc-4d43-82a7-39bb2988dc93" alt=""><figcaption></figcaption></figure></div>

The "**found"** status then stays displayed for 3 days on your platform before returning to the base "**equipped"** status.
{% endstep %}

{% step %}

Click "**Add an alert"** to activate your configuration.\
The alert will then appear in the list and will run automatically according to your settings.
