You can receive notifications on your phone if there’s an emergency while you are away; however, you need to buy a Wink hub to do so, which is an extra expense. Of all the smoke alarms we reviewed, this Kidde model fared the worst in our detection tests. Smoke must be very dense and concentrated for the alarm to sound. This underscores the need for multiple smoke detectors in several places in your home.

Other smart smoke alarms have more traditional warranties that last only a couple years. This smoke detector also has a carbon monoxide sensor to further improve the safety of your home. If it detects a problem, you'll get three alerts: a loud tone, voice alerts and a mobile notification to help you respond to the situation accordingly. We found this unit easy to set up and connect to Wi Fi.
