LinknLink - 60GHz Millimeter Wave Radar Presence Sensor eMotion Ultra (compatible MQTT and Home Assistant)

eMotion Ultra Wi-Fi 24GHz mmWave Radar Presence Sensor

Created for today’s smart homes, eMotion Ultra transforms presence sensing with advanced mmWave radar technology and intelligent automation capabilities. It detects movement with exceptional accuracy, even when you remain completely still, and integrates smoothly with platforms such as Home Assistant, Alexa, and Google Home. This all-in-one sensor delivers powerful performance while helping protect your privacy. Whether used for security, energy efficiency, or smarter home routines, eMotion Ultra becomes a dependable hub for your connected space.

Stationary human detection and anti-interference

No more waving at traditional PIR motion sensors. With advanced mmWave radar, eMotion Ultra can identify subtle body movements, including breathing or heartbeat activity when facing forward, while you are seated, resting, or sleeping. In the app, you can create interference zones to ignore objects such as curtains, plants, or pets. A filtering height can also be set to reduce false triggers from fans or pet movement.

Multi-zone positioning and live tracking

One sensor can cover multiple areas. In the LinknLink App, simply tap and draw up to 4 custom detection zones, such as a sofa, bed, or desk, then assign automation rules for each zone through the app or Alexa and Google routines. eMotion Ultra can detect and follow up to 4 people in real time, showing their positions within the monitored range without affecting privacy.

Home Assistant, Alexa, and Google Home

eMotion Ultra works locally for fast integration with Home Assistant and other MQTT-compatible platforms, making entities such as zones, brightness, temperature, and humidity available. When connected to the internet, it also supports Alexa, Google Home, and Siri for third-party control and automation.

IR blaster, brightness, temperature, and humidity

The integrated 360° IR blaster provides universal control for TVs, air conditioners, audio systems, and other devices, with a range of up to 15m (49ft). A built-in light sensor and cable-mounted temperature and humidity sensor monitor environmental changes. Combined with presence detection, these sensors allow more advanced automations and can reduce the need for extra devices.

Alert notifications and cloud data export

Receive instant phone notifications whenever presence, brightness, temperature, or humidity status changes, even when the app is not open. Your data is stored securely in the cloud with a complete 3-year trackable history and can be exported in standard CSV format for review, analysis, or other uses.

BLE hub for extended accessories

eMotion Ultra also functions as a dedicated BLE hub, allowing you to connect and manage a wide selection of LinknLink Bluetooth accessories, including contact sensors, temperature and humidity sensors, fingerbots, curtain openers, and door locks. It supports up to 20 BLE accessories and can sync them with Home Assistant through MQTT.

Double-sided magnetic installation

The upgraded foldable and adjustable stand includes double-sided magnets for flexible placement, including desktop use, wall mounting, or magnetic attachment. Important notice: a certified 5V/2A power adapter is required. Check the Installation Guide in the app for setup instructions. Maximum detection range: 6m / 20ft for moving targets and 4m / 13ft for stationary targets.
