Elgato appears to be growing its stable of home automation devices, with the the first HomeKit compatible motion sensor spotted, called the "Eve Motion."

Spotted at the IFA Berlin trade show by Giga.de, the new motion sensor by long-time Apple accessory vendor Elgato has a 120 degree sensor, has a temperature sensor, and is splash-proof. The device runs on a pair of AA batteries, with a lifetime of a year.

Through the Home app, the motion sensor can be used to switch devices, or as a trigger for pre-configured scenes.

Connectivity is as normal with HomeKit, through Bluetooth or Wi-Fi depending on user configuration and needs. As with any other HomeKit setup, an Apple TV is needed as a hub if the devices are to be accessible outside the local network.

Elgato has not yet officially announced the product. Giga.de expects it to cost around 50 euros ($56 U.S.).
