Apple has recently activated a feature that enables the HomePod and HomePod mini smart speakers to recognize the sound of smoke and carbon monoxide alarms and send a notification alert to your iPhone or iPad. In this episode of our podcast, Thomas Domville walks us through the process of setting this up.

The Sound Recognition feature uses the always-on microphone inside the HomePod to listen out for a home's existing smoke and carbon monoxide detector. When it hears the alarm, the HomePod sends a notification to your iPhone or iPad via the Home app. This means you don't need to invest in new internet-connected smoke alarms systems, as the HomePod can simply enhance the utility of your existing "dumb" offline smoke alarms. If you have HomeKit-compatible security cameras in your house, the notification will include a live video feed so you can remotely assess what's happening.

To enable Sound Recognition, follow these simple steps: open the Home app on your iPhone or iPad, then navigate to the Home Settings -> Safety & Security screen. There, you can enable the Sound Recognition feature. In addition, you can manage critical notification alerts from supported safety and security devices in your home, and even allow home members to "check in" and listen to the sounds in the home. It's worth noting that the Sound Recognition settings can also be accessed via a HomePod's dedicated Settings. Simply perform a long press on the HomePod's tile in the Home app to access its settings.

(If the Safety & Security section is dimmed out, ensure your HomePod and all other Apple devices are up-to-date with the latest software.
