A smart sensor to automate Apple households

This wireless motion sensor is part of Elgato’s lineup of HomeKit-compatible accessories and can be used to trigger “scenes” and rules based on your movement (or the lack thereof) around your house.


Like most HomeKit accessories, the Eve Motion is a snap to set up. It runs on two batteries and uses Bluetooth low energy (BLE) to communicate with your other iOS devices and Apple TV. No hubs or Wi-Fi setup required.

While you can use Apple’s Home app to configure the Motion, it makes more sense to download the dedicated Elgato Eve one, which gives you more options. After inserting the two included AA batteries into the sensor and launching the Eve app, you choose to add a new device and the Eve Motion should pop up immediately. After that, it’s simply a matter of scanning the unique HomeKit code on the sensor with your iPhone or iPad, selecting the room where you’ll be using it, and then updating the sensor’s firmware. All told, the process takes about six minutes.

You can also tweak the motion sensitivity and duration values during this initial app setup. The latter is used to determine how quickly the motion sensor will re-detect motion after it’s been triggered.

As with Apple’s Home app, you can use the Eve app to create “scenes” that execute multiple actions simultaneously with a single command (An “I’m Home” scene could trigger all the HomeKit-enabled lights in your home to turn on when the Eve sensor detects motion, for instance). You can also create timers and rules to set scenes automatically at specific times or with specific motion triggers.

To test the Eve Motion, we used it in various parts of our home—including the living room, basement, bedroom, and office—creating location-specific scenes, timers, and rules based on our movements.
