Even better: If you have a security camera on HomeKit, the notification will also display an image from that camera, making it easier to see if there's a true emergency, or if it's just a false alarm.Īpart from these abilities, the HomePod mini is a great little smart speaker in its own right, delivering great audio for its size, and bettering the Amazon Echo.

Like the Amazon Echo Dot, the Apple HomePod mini isn't a smart smoke detector in its own right, but it can listen for the sound of a smoke or carbon monoxide alarm going off, and then alert you via the HomeKit app on your phone, tablet, or Apple Watch. Alternatively, if you have a Nest Aware subscription (starting at $6/month), you can set your Google Home speakers to listen for alarms. It can also be connected to some of the best DIY home security systems, such as those from ADT and Ring. When enabled, your Alexa smart speakers will listen for smoke and CO2 alarms, and will send you an alert on your smartphone if they hear a siren. If you already have a number of non-smart smoke detectors, an inexpensive option is to use Alexa Guard with one of the best Alexa speakers. We also like that it performs a self-check every month, and can be linked with other Nest Protects. If you have one mounted near your kitchen, it will also send out a warning that it's about to go off, so you can silence it if all you're doing is cooking up some steaks. It's the most full-featured alarm, blaring out a loud siren and telling you where the problem is.

Our favorite for a few years running is the Nest Protect. There's not a lot of choice when it comes to smart smoke detectors.
