Cloud Meta Element

The cloud meta element is used to change the meta information of a device on Atmosphere, such as a device’s geolocation or status. Device status is based on the following priority order, listed from highest to lowest:

• Missing
• Critical
• Warning
• Info
• Good
• None

Status can either be manually set or escalated using the above priority order. For status escalation, the status will increase to a specified state if it’s a higher priority than the device’s current status; otherwise the status will remain in its current state.

The cloud meta element is located in the Element Toolbox within Studio’s Cloud tab.

Properties

The following properties can be changed for the cloud meta element:

Name

The name of the element.

Triggers

The following triggers are available to execute events from within the cloud meta element:

Triggered

Execute an event when the source element connected to the cloud meta triggers.

Abilities

The following abilities are available for the cloud meta element when its source element triggers:

Trigger
