Not worth it
Review: I purchased seven of these alarms in 2021 (five standard and two speaker models). Unfortunately, we’ve experienced around a dozen false smoke alarms over the years, almost always in the middle of the night. The most recent one woke the entire house at 3:44 AM with no smoke or fire present. The smart features have also been disappointing. The app often provides little useful information after an alarm, and it doesn’t reliably identify which detector actually triggered the system. HomeKit...
False Alarms and End of Life after 2 years
I purchased 7 of these for a new home build with vaulted ceilings. I wanted ones that I could silence through an app on my phone because I knew reaching them was going to be almost impossible with them mounted about 14 -- 22 feet up on the ceiling per code requirements. Getting them to register with my WiFi for app alerts was difficult to begin with but after I finally got them connected, I found that the control for silencing them was a Bluetooth connection and doesn't even go through the WiFi....
10 year device didn't make it 3 years.
[Employee of lowes] It was easy to set up, and I really liked some of the features. I liked having multiple devices linked so if an alarm is activated in the kitchen it will also announce in the bedrooms. Occasionally the kitchen device is activated when cooking and I really like being able to silence it from my phone instead of getting out the ladder and climbing up to press the button. Unfortunately the 10 year battery lasted less than 3 years. I contacted the manufacturer who said that...

No better than a "dumb" alarm
I bought this hoping I could add one smart alarm, interconnect it with my existing First Alert "dumb" alarms, and receive notifications on my phone. I hooked it up, tested it by setting off another alarm in my house, watched it too go off with all of the others, and then waited, waited, and waited for a notification that NEVER came to my phone. I also tried by setting off this Onelink alarm directly but still no notification despite it blaring as loud as possible that I needed to evacuate. I set...

Looks good but a few minor issues
Looks good. Easy to install except that the screws provided were poor quality and did not fit holes in junction box. Setup in the app took two tries, but ended up working. Unit has a nightlight that can be dimmed in the app, but it doesn’t turn completely off and while the manufacturer online description showed the light color could be changed, this does not appear to be possible in the app. The square shape means you have to pay attention to the alignment of the bracket so that the unit does no...

Great product, crappy tech help
The alarm was easy to setup, but when I migrated to a new network, the alarm was unable to complete Wi-Fi connection process, after a factory default reset. Customer service escalated to tier 2 when I called the first time, promising a return phone call or email. I have yet to hear back from Tech help. Customer service hints at an issue with mesh Wi-Fi, but nothing concrete. The I only communication I received was a request for a review of the customer service department, as of one week after...

Total junk, please stay away!
I need to replace 6 smoke/co detectors. My requirement was Apple HomeKit integration, and to my surprised, this is the only model that does it. This detector is soo dumb it is shame that they call it smart. The HomeKit integration is useless, it takes many tries to setup (must first setup thru OneLink app which half the time does not work); second, you can't do anything with it inside HomeKit - for instance, I cant control the light which also has minimal controls inside the OneLink app. I am a ...

Great Smart Product
I have two of these First Alert alert detectors in my home. I will be converting the other 3 detectors in my home. The app was easy to use and I was able to connect it to my Apple Homekit very easily. I really like that each detector you add connects to the others and they work together. I ran a test and when I made the smoke detector go off in one room it lets you know what room has the issue and the other detectors tell you that information. It also will send you a notification to your phone. ...
Get beyond programming. Works great/functional
Would of been 5 Stars but had initial programming issues. Install of the actual device was easy. Programming had glitches and was initially frustrating. Called company for assistance, they were helpful. Discovered we needed to install & PROGRAM one alarm at a time. App is functional, light birghtness is adjustable. Of course we will see over time how alram actually works.
So many false alarms
These were easy to install. Our family was excited to have an extra layer of protection in our home. Then came the torment. These alarms have gone off so many times. My kids no longer exit the house. They come to me and tell me to turn it off. My younger kids wake up from naps in complete terror. Oh and when it comes to shutting them off, the buttons don’t work. After less than a year of owning them we have had to completely hardwire remove them to disable the false alarm. Yet when actual smoke ...
