Another owner noted that the mounting bracket is nonstandard, and it took a lot of effort to attach the smoke detector. "Alexa integration is pretty good," she write, "but you can't change the wake word, which is a problem if you have two installed within earshot of each other. And I kind of had to speak loudly to get its attention in a room with an air conditioner. Which meant that the upstairs one heard me, too. But, hey, it plays music. And the speaker's okay.

Yellow means there's a malfunction or a low battery, while red means there's a fire or smoke condition. Onelink's alarm uses photoelectric technology, which is generally better at detecting smoldering fires than are alarms that use ionization technology. However, the latter are better at detecting fast burning fires. The Onelink can be connected to HomeKit and Alexa but not Google Assistant, so you can ask both Siri and Amazon's voice assistant for the status of the smoke detector, but not much else. By contrast, if the Nest Protect detects fire or carbon monoxide, you can have it automatically turn on a security camera, open Lutron blinds, turn on Philips Hue lights, turn off your heat and more. Setup should theoretically be easy—just scan a HomeKit code in the Onelink app—but it took a few tries to get it to work. The Onelink smoke and carbon monoxide alarm is good on its own, but the Nest Protect does more for the same price. What to look for in a smart smoke detectorFire and smoke detection sensors. All smoke detectors use one of two types of sensors to detect fires. Ionization type sensors are best at detecting fast burning fires, while photoelectric sensors are generally better at alerting you about smouldering, or slow burning fires. You should have both types of alarms in your house.

UL is not alone in this recommendation; many other fire safety organizations make the same suggestion. If you want more information on smoke detectors, we recommend checking out the National Fire Protection Association's helpful guide, "Safety Messages About Smoke Alarms. "How We TestedEase of UseOur testing team built a custom apparatus designed specifically to analyze each smoke alarm’s detection capabilities. It was placed in the center of a room measuring 25. 33 x 18. 83 feet. We mounted and hardwired each of the detectors to the apparatus and noted how long it took to install each one using the included manufacturer instructions. After connecting each alarm to a Wi Fi network, we installed its associated mobile app on a smartphone. We evaluated how easy each app is to use and tested how long it takes for notifications to arrive on your mobile device when there is an emergency. We also assessed how well each device connects to third party smart home automation systems. We contacted each company, when possible, to assess how helpful its representatives are when resolving potential technical problems.
