# Device Lifecycle Reports

Akenza provides *daily* or *weekly* email reports on **device health** at the **Workspace** level, identifying *offline* devices, *weak* signals, or *low battery* levels. Each email includes a comprehensive list of new and ongoing alerts in each category, along with direct links to inspect the affected devices.

You can manage device lifecycle reports on the **General** page within the **workspace settings**. Any **Workspace Admin** can enable or disable these lifecycle notifications and manage a recipient list that can include multiple recipients.

![Lifecycle notifications](https://2165942204-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MMKXTFIN5ZlLOjBlfC4%2Fuploads%2FSvhEKyt3NSD6c2OrbIU6%2Fscreely-1685030703270.png?alt=media\&token=cd058f9d-bc08-4432-92a7-9675fb563bac)

On workspace creation, the notifications are **enabled by default**, and the workspace creator is set as the default recipient.

### Notification criteria

#### Offline

In order for a device to be marked as offline, the specified offline timeout is compared to the timestamp of the last received message. If the difference exceeds the specified threshold the device is marked as offline. 

{% hint style="info" %}
This metric is available for **all devices.**
{% endhint %}

#### Weak Signal

If a device reports a **Signal Quality Indicator (SQI)** of 1, it marked as having a **weak signal**. 

More information about SQI can be found in the [Uplink Metrics](https://docs.akenza.io/akenza.io/create-new-device/devices#uplink-metrics) section of the device reference.

{% hint style="info" %}
This metric is available for **LoRa devices** only.
{% endhint %}

#### Low Battery

If a device reports a battery level of **20% or lower**, it is counted as having a **low battery**.

The battery level can be calculated in a script or directly sent in the uplink payload (for passthrough devices). More information about Battery Level can be found in the [Uplink Metrics](https://docs.akenza.io/akenza.io/create-new-device/devices#uplink-metrics) section of the device reference.

{% hint style="info" %}
This metric is available for all devices, given the uplink payload or resulting sample contains the specified key and value which is used to determine the battery level.
{% endhint %}
