Expand your Elgato Eve collection with the Elgato Eve Smoke. Connect the smart smoke detector to the free app on your smartphone (note: iOS only) and to Apple HomeKit. When the detector detects smoke, an alarm with an 85-decibel audio signal will go off. You'll receive a push notification on your phone at the same time. You'll always be notified in case of danger in your home. The smoke detector automatically checks if everything still works once a month. You'll receive a notification of this in the app. This way, you can be sure the smoke detector is still operational. The battery lasts for 10 years, so you won't have to worry about that anytime soon.
