Event is generic concept that allows to track, log, and work with important events that happen on the device.
Additionally to the historical event tracking, events can also be used for notifications which can be sent over email, delivered as push notifications to user's smartphone, or sent as an SMS.
Events are pre-configured in Blynk.Console and can be triggered with a from device or using .
Examples of an Event:
Log a moment when a temperature reached a certain threshold and send a notification to selected users
Track total working hours of the device. If it approaches or goes beyond a max value, you would need to notify technical support so that they can replace the device or provide warranty service
There are three types of Events in Blynk:
System Events: Default Blynk platform events.
Custom Events: Events you can create and configure for your needs
Content Events: Informative events that are shown separately in the app
You can't delete the system events, but you can configure them.
