Read the full reviewBest ValueKidde KN COSM B RF$49. 72 View at AmazonCheck Walmart?Detects both smoke and carbon monoxideDoesn’t require a hardwired connectionCan connect to multiple alarms via Wi FiPerformed poorly in our detection testsRequires extra equipment for the mobile appOnly compatible with Wink smart home platformThis alarm is two devices in one: a smoke detector and a carbon monoxide detector. It’s very easy to install
because it runs on changeable batteries so you don’t have to hardwire it into your home’s electrical grid. If the Kidde KN COSM B RF detects an emergency in your home, it sets off a tone alarm as well as a voice alarm that gives instructions and tells you what the danger is. It also uses voice notifications to let you know when you need to change the battery. If you buy more than one of these detectors – and you should!– you can network them through your home’s Wi Fi network. Once they are connected to the internet, you can
download the Wink smart home app to control your smoke detectors, as well as many other devices, remotely. You can receive notifications on your phone if there’s an emergency while you are away; however, you need to buy a Wink hub to do so, which is an extra expense. Of all the smoke alarms we reviewed, this Kidde model fared the worst in our detection tests. Smoke must be very dense and concentrated for the alarm to sound. This underscores the need for multiple smoke detectors in several places in your home.
