The Kidde Smart Smoke Alarm with Ring ($54.97) and the Kidde Smart Smoke and CO Alarm with Ring ($74.97) are hardwired alarms with battery backup. They will launch this April at The Home Depot and come to more retailers later in 2025, according to Kidde.

While smoke and fire are always top-of-the-list for a smoke detector’s priorities, the best smart smoke detectors can detect many hazards, including carbon monoxide, natural gas, VOCs (volatile organic compounds), and radon. Some of the most advanced models can even monitor for fluctuations in temperature, humidity, and air quality.

Ring is teaming up with Kidde on a collection of Smart Smoke and Combination Alarms (Smoke + CO) alongside a new optional 24/7 Smoke & CO Monitoring service.

Kidde fire and smoke detectors (some of our favorites) now work with the Ring security app at CES 2025, and Ring's got a new monitoring plan to match.
