This component allows building email message by substitution of device attributes and message data into configurable templates.
During action configuration you are able to specify following templates: from, to, cc, bcc, subject and body. The template syntax is based on Velocity and is already described in alarm processor documentation.
Additionally, you can specify Send Flag property. This is an optional property that may be used in combination with isNewAlarm or left blank.
As a tenant administrator, you are able to review action example inside Rules->Demo Alarm Rule->Actions->Send Mail Action.
