The LinknLink eMotion Ultra is a versatile presence sensor designed to automate your home by detecting human activity with high precision. It utilizes 60GHz mmWave radar technology, which allows it to track up to four people in real-time, sensing movement up to 6 meters away and detecting stationary individuals within a 4-meter range. To give you more control over your environment, you can configure up to four customizable 3D detection zones, ensuring the sensor only triggers actions in specific areas of a room. Beyond motion sensing, this compact round device serves as a powerful control center. It features a 360-degree IR blaster with a 15-meter range that can manage your infrared appliances, while the integrated brightness sensor and the included on-cable temperature and humidity sensor provide comprehensive environmental data. Because it acts as a BLE hub, you can connect up to 20 LinknLink accessories, such as contact sensors or fingerbots, consolidating your smart home ecosystem into one point. Measuring 61 x 61 x 25 mm, the unit is designed for flexible placement using a foldable adjustable stand equipped with double-sided magnets, making it easy to set on a desk, attach to a wall, or snap onto a metal surface. It connects via 2.4GHz Wi-Fi and Bluetooth, integrating locally with Home Assistant through MQTT, as well as with Alexa, Google Home, and Siri. The device is powered by a USB-C connection and is compatible with iOS 11.0 or Android 5.1 and above.
