What feature distinguishes a smart smoke detector?

A smart smoke detector is distinguished primarily by its ability to connect to a home Wi-Fi network. This connectivity allows the device to communicate with other smart home systems and devices, enabling it to send alerts to smartphones or other devices when smoke or carbon monoxide is detected. This feature enhances the functionality of the smoke detector beyond traditional alarms by providing real-time notifications and remote monitoring capabilities.

In contrast, while some smart smoke detectors may indeed have a louder alarm, that is not a defining characteristic of what makes a smoke detector "smart." The use of batteries is common in both traditional and smart detectors, so this feature does not differentiate smart devices from conventional ones. Additionally, while professional installation may be recommended for certain models, particularly those integrated into broader security or smart home systems, many smart smoke detectors are designed for easy DIY installation. Therefore, professional installation is not a characteristic that specifically defines a smart smoke detector.
