3. Operating Instructions
3.1 Remote Monitoring and Notifications
Once sub-devices are paired with the S3 Hub, you can monitor their status remotely via the BroadLink app. For example, with a door sensor, if someone opens the door, you will receive an instant notification on your phone, allowing you to react promptly.
3.2 Home Security Applications
The S3 Hub and its connected sensors can enhance your home security. By receiving real-time alerts for events like door openings, you can be informed of potential intrusions and take necessary actions.
