First Alert OneLink Wi-Fi Smoke and CO Alarm Review – Is It Really Smart?

The First Alert OneLink Wi-Fi Smoke and CO Alarm is HomeKit’s answer to the Nest Protect. It has a very good list of features that would make anyone want to go up and buy it immediately. But that list is only good on paper and not when it comes to actual performance. It is able to do quite a bit from push alerts to in-app silencing for false alarms. However, it suffers from a lot of mishaps and poor performance that makes this device hard to recommend.

First Alert OneLink Wi-Fi Smoke and CO Alarm Review - Is It Really Smart?

The First Alert OneLink Wi-Fi Smoke and CO Alarm Has a Performance That Only Looks Good on Paper

The First Alert OneLink Wi-Fi Smoke and CO Alarm comes in two versions – one hardwired and one battery-powered model. The latter is placed in a lower price point than the former, but the difference between the two models in terms of price is small and very forgivable.

At its core, it is a smoke and CO alarm. When it detects such elements, it will consistently respond by blaring its warning. In this aspect, it does even better than that of the Nest Protect. As for the accompanying app, for now it only offers the basics. Still on the app, it’s not the most useful one out there. To start, push notifications are horrendously slow, and for the most part become meaningless. This makes the connected functionality to be not as good enough. There are room for updates and hopefully First Alert would take heed of the shortcomings of their app.

But before you are faced with a lot of disappointment, the First Alert OneLink Wi-Fi Smoke Alarm does give out a stupendous performance when it comes to giving first impressions. The hardware is very solid, as it should be since it is made by a company known for manufacturing sturdy safety devices and products. The design looks great and installation is quite simple to accomplish.

For the alarm itself, it does offer solid smoke and CO detection performance. If someone is within hearing distance of its loud alarm, then you and your family can have better peace of mind. But if someone is outside hearing distance from the alarm and the only reliable way to know if the device detects smoke and CO is through the app, then there might be cause for worry.

Because of this, the First Alert OneLink Wi-Fi Smoke and CO Alarm is only ideal for places wherein there would always be a person that could hear the alarm should it detect smoke and/or CO. Relying solely on the app is not recommended at this time, unless First Alert does something with it to improve its performance.
