Notifications (Alerts)

Notifications/Alerts is a crucial part of any IoT solution. Blynk offers extensive set of features to send and receive in-app (push), email, and SMS notifications from devices.

There are three main approaches you can take:

1. End-users can set up Notifications using Automations (if allowed so by their role and set of permissions). Once Automation is set up, Blynk.Cloud monitors the data and sends notification to the specified recipients when the condition is met.

2. Device-driven notifications

3. Content events
