Meet LinknLink eMotion Pro
LinknLink eMotion Pro is a smart presence sensor that combines powerful 24GHz mmWave radar technology with local intelligence to deliver accurate, real-time human presence detection—even when the person is completely still. Unlike typical PIR sensors that rely on motion, the eMotion Pro uses millimeter-wave radar to detect micro-movements like breathing, enabling smarter and more nuanced automations across a wide range of indoor environments. Despite its compact size, it packs in a rich feature set including distance sensing, 2D zone detection, ambient light measurement, and an integrated IR blaster. Whether you’re building a more responsive smart home or deploying automation in commercial spaces, eMotion Pro is a quiet powerhouse.
What sets the eMotion Pro apart from traditional motion sensors is its ability to detect stationary human presence—even if you’re sitting still or lying down. This alone is a game-changer for avoiding the constant frustration of lights turning off when you’re quietly reading, working, or watching a movie. With a detection range of 6 to 7 meters, the eMotion Pro surpasses many competitors in coverage. It accurately measures distance with up to 1 cm precision, enabling automations that react not just to presence, but to proximity. For example, dim the lights as you approach the bed, or gradually increase brightness as someone walks into a workspace.
While the eMotion Pro doesn’t offer 3D positioning like its sibling, the eMotion Max, it still excels in 2D zone detection—ideal for setups where defining zones like sofa, bed, or entryway on a flat plane is sufficient. You can assign actions to each area with simple drag-and-drop mapping in the LinknLink app.
A standout feature is the built-in IR blaster, allowing the eMotion Pro to function as a universal remote for AC units, TVs, fans, and more. Unlike the eMotion Max, which supports IR only through the app, the eMotion Pro adds compatibility with Home Assistant, making it even more useful for fully localized automations. The ambient light sensor adds another layer of intelligence. With real-time lux data, the sensor can help prevent wasteful lighting by only triggering illumination when the room is both occupied and dim.
Out of the box, the eMotion Pro supports MQTT, enabling fast, local communication with Home Assistant or other platforms. You get immediate access to distance, zone, and brightness data—no cloud required. This ensures not only lightning-fast automations but also local privacy and reliability. Whether you’re building a fully offline smart home or integrating into a complex commercial setup, the Pro’s native support gives you total control. The eMotion Max is ideal for users who need multi-person tracking, 3D spatial awareness, and advanced care monitoring—especially useful for elder care or hospitality environments. In contrast, the eMotion Pro is better suited for users looking for high precision, strong distance detection, and full IR control integration with Home Assistant, all at a more affordable price point.
The LinknLink eMotion Pro is a refined, responsive, and highly intelligent sensor for anyone looking to enhance their smart home with precision presence detection and local automation. Its combination of distance sensing, 2D zoning, and tight integration with Home Assistant gives users reliable control without relying on the cloud. For homes where privacy, responsiveness, and affordability matter, the eMotion Pro is a top-tier choice. Whether you’re looking to improve automation accuracy, reduce false triggers, or monitor occupancy non-intrusively, the eMotion Pro delivers exceptional value and versatility. Highly recommended for any serious smart home setup.
LinknLink eMotion Pro Main Features
– Precise Stationary Presence Detection. Millimeter-wave radar detects human presence—even if the user is sitting, lying down, or asleep—with high accuracy and without false positives from pets or background movement.
– Distance Detection. Unlike many radar sensors, eMotion Pro can estimate the distance of the target from the sensor (with ~1 cm precision), which can be used to trigger proximity-based automations.
– 2D Zoning Support. Define zones within a room (e.g., desk, bed, couch) using a simple 2D map via the LinknLink app, allowing different automations based on where someone is detected.
– Ambient Light Sensing. Built-in light sensor allows for automations that consider real-time brightness levels—great for adjusting lighting based on time of day or occupancy.
– Smart Integration Options. Supports MQTT, Home Assistant, Google Home, Alexa, and Apple Siri Shortcuts. Works locally over WiFi without needing cloud access.
Real-life scenarios where LinknLink eMotion Pro can be quite useful
– Smart Living Rooms: Trigger lights, fans, or entertainment systems when you enter specific zones.
– Bedrooms: Sleep detection avoids false triggers from minor movements.
– Elderly Monitoring: Real-time presence and inactivity tracking enhances care and safety.
– Home Offices: Automate lighting or HVAC based on seated presence.
– Short-Term Rentals: Monitor guest count without cameras, preserving privacy.
– Children’s Rooms: Detect presence and send alerts if no movement is detected for extended periods.
– Kitchens: Automate lighting or exhaust fans when someone enters and stays within the cooking zone.
– Bathrooms: Turn on mirror lights, warmers, or ventilation only when someone is present.
– Walk-in Closets or Pantries: Trigger lights only when someone steps inside, conserving energy.
– Media Rooms: Start movie mode (dim lights, close blinds, power on projector) when someone enters and sits down.
