LinknLink eMotion Pro Presence Sensor — 24GHz mmWave, WiFi, MQTT, Alexa & Google

Meet the LinknLink eMotion Pro Presence Sensor

The eMotion Pro is a compact, WiFi-enabled presence sensor built around 24GHz third‑generation mmWave radar. It detects occupancy with high precision and integrates smoothly into modern smart homes without a hub. With native compatibility for Home Assistant via MQTT, and support for Alexa and Google Assistant, you can craft responsive scenes that adapt to real-world movement and light levels while keeping setup simple and scalable.

Designed for flexible installation, the sensor shines in a variety of spaces—from open living areas to cabinets or awkward corners—thanks to its broad front‑side detection range and barrier‑breaking capability. The device not only detects presence but also interfaces with other devices through its infrared (IR) blaster and a built‑in brightness sensor, enabling nuanced automations that react to ambient light and user activity.

What it detects and how it helps

• 24GHz mmWave radar offers precise presence detection, reducing uncertain triggers and ensuring smarter room awareness.
• Wide detection up to 6 meters supports flexible placement and reliable sensing from multiple angles.
• Direction-agnostic sensing allows placement in a variety of orientations, including concealed spots like cupboards.

Smart control at your fingertips

• IR control extends reach up to 15 meters, enabling remote operation of compatible devices such as lights or climate controls.
• Built‑in brightness sensor provides ambient light context for smarter lighting and climate automation.
• Seamless automation with Home Assistant via Motion2MQTT bridges presence data to your routines and scenes.

Seamless integration and voice support

• Alexa and Google Home compatibility unlocks voice alerts and routine triggers based on presence.
• No hub is required—connects over WiFi for a quick, plug‑and‑play setup that scales with your smart home.

Remote monitoring and real-time insights

The LinknLink app keeps you informed with real‑time alerts, activity history, and easy data export. Android and iOS widgets provide quick status checks, so you stay in the loop wherever you are.

Compared to traditional sensors, the eMotion Pro emphasizes practical benefits: accurate presence cues, flexible placement, and a cohesive automation workflow that can evolve with your needs. While outcomes depend on your unique setup and routines, the device is designed to offer reliable signals you can build on without overpromising results. Use it to shape lighting, climate, and security workflows that feel natural and effortless.
