Back in January, Apple announced a new Sound Recognition feature alongside the launch of the HomePod 2. The feature lets your HomePod listen out for your home's smoke and carbon monoxide detectors and alert your iPhone via the Home app. It's a really nice addition to Apple's smart speaker that helps with knowing what's happening at home when you're out and about.

The feature uses the always-on microphone in your HomePod, HomePod 2, or HomePod mini, so you don't have to buy a fancy HomeKit smoke alarm. Now, Sound Recognition is finally available, and it's worth trying. Here's how.

Disclaimer: Apple's HomePod cannot be used as a smoke detector. This feature enables your HomePod to listen out for the sound of existing detectors in your home, and will only alert you if it hears an existing alarm. 

How to enable HomePod Sound Recognition

  1. Open the Home app
  2. Tap the three dots in the top right corner
  3. Tap Home Settings
  4. Choose Safety & Security
  5. Turn Sound Recognition on

You'll need the latest update for your HomePod and your Home app with the latest architecture, so make sure everything is up to date; otherwise, the option will be greyed out.

It's straightforward to set up and a fantastic new free feature to add to your HomePod to make it an even better smart home device. 

Make your home smarter

The Sound Recognition feature is a welcome addition to the HomePod lineup. It gives users added smart home functionality without purchasing one of the best HomeKit smoke and CO detectors

If you're ever worried that the fire engine speeding past is heading toward your apartment block, then worry no more, as HomePod's new feature will notify everyone in your household if a noise is detected. Hopefully, this is the start of further HomePod updates that can make devices more useful without looking for more HomeKit accessories.
