I've been using the Meross Smart Smoke Alarm for about two months now, and I'm impressed. Setting it up with Apple HomeKit was a breeze, and I love that I can check the status from my phone. The overheating detection is a great feature, and the alarm is plenty loud enough. I even set up an automation to turn on the lights in the hallway if the alarm goes off. Great addition to my smart home!
I bought the Meross Smart Smoke Alarm with Hub after researching several options, and I'm so glad I did. The interlinked alarm system is fantastic – if one alarm goes off, they all do! I tested it, and it works perfectly. Installation was super easy, and the app notifications are instant. Knowing I'll get alerted even when I'm not home gives me real peace of mind. Definitely recommend for anyone serious about home safety.
