The Google Nest Protect S3000BWES is a smart smoke and carbon monoxide detector that offers several advanced features. It provides early warnings in a friendly voice and sends phone alerts, even when you're away from home. The Split-Spectrum Sensor detects fast-burning and smoldering fires, while the CO detector identifies the location of carbon monoxide. 

With the Nest app, you can silence the alarm and receive low-battery notifications. The device also offers a Pathlight feature and self-testing capabilities. It provides phone alerts and remote silencing, offering enhanced safety and convenience for connected homes.

Google Nest Protect - Smoke Alarm - Smoke Detector and Carbon Monoxide Detector - Battery Operated , White - S3000BWES  - Best Smart Smoke Detectors Guide, smart fire alarms - grandgoldman.com

The Nest Protect has truly revamped home safety for me. I've got both the first and second-gen versions, both wired and battery-operated, totaling six for my house. The second-gen outshines the first in almost every way, except for one hiccup I'll get to in a bit.

Setting these up is a breeze, and they seamlessly join my Nest device family. Installation is straightforward, and the app integration makes monitoring a breeze. The path light feature is a game-changer, providing just the right illumination in the dark. The rectangular design can be a tad tricky to align, especially on ceilings in hallways, but it's a minor trade-off. I appreciate having a couple of wired ones to track power cuts – a handy feature for both safety and my curious mind. The app's history and Nest integration enhance the overall experience.

Despite a few install quirks and a slightly steeper price tag, the Nest Protect is a solid investment for safety-conscious homes. The path light alone adds a practical touch, and the photoelectric sensors ensure top-notch fire detection. While some may grumble about the 10-year replacement cycle, the safety it provides is worth the periodic upgrade in my opinion.






2. X-SENSE: Best value

What a nifty gadget—I'm thrilled I picked it up! Despite having regular smoke detectors in my place, this smart one has added a whole new layer of peace of mind, especially with two dogs in the house.

X-Sense Smart Smoke Detector Fire Alarm with Replaceable Battery, Wi-Fi Smoke Detector, App Notifications with Optional 247 Professional Monitoring Service, XS01-WX - Best Smart Smoke Detectors Guide, smart fire alarms - grandgoldman.com

First off, it's tiny! Much smaller than I expected, but the fact that it's packed with "smart" features at that size is impressive. Downloading the app, setting up an account, and seamlessly adding the detector is a breeze. Mounting it on the wall is a piece of cake. After that, a quick test from the app lets you check its status, test the alarm, monitor battery life, and even assess the signal strength with your router.

You can also add a friend or neighbor to your account, so if the alarm goes off and isn't silenced in time, it sends a notification to them. Of course, it alerts you too. While there are paid services for automatic fire truck dispatch, I find the free features more than sufficient.

My main concern was being notified of smoke or fire when I'm away, ensuring a quick response from a neighbor who could help save my dogs if needed. The fear of a fire while I'm out has always lingered, but this little device has given me the confidence to go about my day worry-free. Plus, it's LOUD! Highly recommend.






3. KIDDE: Easiest to install

I've been on the hunt for a smart smoke detector that isn't Nest for nearly two years—I'm just not into Google products. Finally stumbled upon this gem, and it's the first one that actually does the trick. Setting it up was a breeze, but I must admit, I've got a knack for electrical stuff. Swapped out an 8-year-old hardwired First Alert smoke detector, disconnected the wire connectors, and voila, I already had a neutral wire in place. Lucky break, or maybe that's just the norm—I'm not quite sure.

Installed the new harness, followed the instructions to download their app, and synced up the smoke detector. Exactly what I was looking for, and the price was right on the money. The only improvement would be if Kidde had integrated with Home Assistant, but it seems the Home Assistant community is on the case.

I had a prior run-in with a another brand smart smoke detector. Utterly useless as a smart device—it only syncs with Apple HomeKit, which is a pain to use. The Kidde device is miles ahead, no contest.

Having lived with six Onelink Safe & Sound devices for a few months, I've become well-acquainted with their perks. Here's a rundown of what I value most, listed in order of priority:

AirPlay 2 Speakers: The standout feature for me. These devices serve as AirPlay 2 speakers, offering seamless whole-home audio for Apple iPhone, HomePod, or AppleTV users. With power wired to all smoke detector locations in my home, I can play music throughout, syncing perfectly between devices.

HomeKit Compatibility: Being Apple HomeKit-compatible means these devices integrate seamlessly with the Apple Home app, allowing convenient control via Siri.

Multi-color LED Night-light: The customizable night lights illuminate hallways and stairwells. Using HomeKit's automation, I tweak the color and brightness based on the time of day, adding a practical touch to the home.

Easy Installation: Replacing existing wired smoke detectors is a breeze with a ladder and screwdriver, taking only about 3 minutes per room. This simplicity is complemented by the ingenious use of AC power for whole-home audio.

Smoke & CO2 Detection: While I haven't experienced a fire, the First Alert reliability assures me of their effectiveness. These devices offer more than just smoke detection, making them a comprehensive choice.

Alexa Capability: Although I'm an Apple enthusiast and seldom use the Amazon features, the built-in Alexa capability works fine for tasks like controlling smart lights.

In a nutshell, Onelink Safe & Sound goes beyond the mundane smoke detector, enhancing my home with music, smart features, and peace of mind. Despite the higher price point, the combination of safety and smart functionality justifies the investment.

This is a great product. I have a separate garage, an attic and a basement where a regular smoke detector would not provide a proper warning in case of a fire. This is a great system. First, they make a lot of noise when activated. But better still, you get an alert on your cellular phone. 

If there is a fire when you are not home, you will know instantly, and can call for help. Every smoke detector should be WIFI enabled.

These are both smoke detectors and carbon monoxide detectors, so two birds with one stone. I had to rewire my ceiling a/c wires since the old alarm plug-ins didn't fit these. As can be seen, these come with their own wire plug-in set up. I pressed the middle button to test, and all three worked in unison. 

Nice voice warning with this detector too. I like the illuminated green ring around the test button showing it is active. Some rudimentary electrical know-how is needed for the wiring part. For the price, this 3 set is great.

We all need smoke and CO2 detectors, but they wear out, and codes change. Despite having wired smoke and plug CO2 detectors, I realized I lacked one on the first floor. I appreciate the working LED, voice announcements, and the app's ability to provide current and past readings. 

Installing multiple units enables communication for those crucial extra seconds to reach safety. Now, I'm considering more for each bedroom. Setup was a breeze, and everything is included. While pricier than budget options, the peace of mind is priceless. Remember to change batteries annually; the detector should last a solid 10 years.
