This device tells you whether your door or window is open or closed and sends notifications to your iOS device via Bluetooth. The app can give you statistics on the time and duration a door opens and closes. It works with Siri, allowing you to ask for the current open/closed state of a door in your home.
The best thing with this is it works with Apple HomeKit, which gives you full control of your smart home devices. You can set your other HomeKit-enabled devices to automatically respond with Eve Door & Window’s sensors. You can now set your AC to turn on when you open your front door from work or set your coffee maker to start brewing when you open your door from your bedroom in the morning.
It runs on long-lasting, replaceable ½ AA batteries, eliminating the hassle of dealing with power cords.
