What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the hardwired version of Kidde's smart smoke + CO alarm is the right pick when local code (or an existing hardwired system) forces your hand, but it earns the most polarized signal mix in this pool. Good Housekeeping's review praised the Wi-Fi-enabled real-time alerts and noted the alarm sits at about twice the price of a non-smart equivalent. Costco.com verified-purchase reviewers describe the units as premium-feeling and responsive in tests.
What reviewers liked
- AA battery backup keeps detection alive during power outages
- Hardwired interconnect meets code requirements in most jurisdictions
- Good Housekeeping recognizes the Ring-integrated Kidde line for real-time phone alerts
- Voice alerts distinguish 'Fire' from 'Carbon Monoxide' instead of generic beeps
- Drop-in compatible with existing Kidde hardwired alarms
Where it falls short
- 3.5-star Amazon average across 134 reviews is notably weaker than non-smart Kidde alarms
- r/Ring users document significant setup and notification-management headaches in multi-detector homes
- r/firealarms specialists explicitly recommend avoiding 'smart' detectors for life-safety duty
- Requires hardwiring — DIY install is harder than battery-only alternatives
- Some advanced Ring monitoring features require a paid subscription
Across the reviewers we read, the hardwired version of Kidde's smart smoke + CO alarm is the right pick when local code (or an existing hardwired system) forces your hand, but it earns the most polarized signal mix in this pool. Good Housekeeping's review praised the Wi-Fi-enabled real-time alerts and noted the alarm sits at about twice the price of a non-smart equivalent. Costco.com verified-purchase reviewers describe the units as premium-feeling and responsive in tests. r/homeautomation and r/smarthome regulars are broadly positive on Kidde's hardwired interconnect ecosystem.
The disagreement is loud, though. The Amazon rating sits at 3.5 stars across 134 reviews — well below the rest of the Kidde lineup — and a widely-cited r/Ring thread titled 'Kidde Ring Smoke Detector nightmare' details setup struggles across an 8-detector install. r/firealarms commenters specifically caution against consumer smart alarms when reliability is paramount. Reviewers agree the underlying detection hardware is fine; the friction is on the Ring app side, which is exactly where the 'smart' premium goes. Buyers replacing an existing Kidde hardwired chain will likely find the upgrade smooth; buyers starting from scratch with many units should brace for app friction.

When every second counts, this Wi-Fi-enabled alarm sends an alert to your smart phone.
Just remember they should be replaced every 10 years. Most places require hardwire to meet code. I used this model from first alert SMICO105-AC.
I love my kidde detectors, 120v powered, interconnect wire so we don't miss an alarm in the basement untility room, 10 year lithium battery ...
