Meet LinknLink eMotion Max
As smart home technology continues to evolve, precision presence detection is becoming a cornerstone of effective automation. The LinknLink eMotion Max sets a new benchmark in this category by combining 60GHz mmWave radar, IR remote control, and a light sensor into one powerful, cost-effective package. Designed for seamless integration with platforms like Home Assistant, Alexa, and Google Home, the eMotion Max goes beyond basic motion sensing to deliver zone-based tracking, multi-person detection, and even ambient light monitoring.
The LinknLink eMotion Max is arguably the most advanced and affordable radar-based presence sensor currently available. Its multi-zone tracking, real-time human detection, IR control, and native Home Assistant support make it an all-in-one solution for smart home enthusiasts and professionals alike.
The unboxing experience of the eMotion Max is straightforward and satisfying. Inside the minimalist yet informative packaging, you receive the eMotion Max sensor unit with its sleek, round design, a USB-C power cable, a wall mount with an adhesive pad, a quick start guide, and a safety and regulatory information sheet. The device itself feels premium in hand, featuring a smooth matte finish and a compact form factor measuring just 61 by 61 by 25 millimeters, allowing it to blend seamlessly into any room’s decor without drawing attention.
Using the eMotion Max in my own space truly felt like stepping into a smarter, more responsive environment. From the moment I powered it on, its 60GHz mmWave radar impressed me with just how accurately it detected presence — not just movement, but subtle things like when I was sitting still working or even lying down reading. Unlike PIR sensors I’ve used before, there were no false triggers from sunlight or passing pets, and it could “see” through curtains without issue. Setting up zones through the app was intuitive and surprisingly powerful. I defined areas for the sofa, desk, and entryway, and quickly set automations — lights would fade on when I walked into the living room, and my AC kicked in only when I sat at the desk. It’s incredibly satisfying watching your home respond so precisely to where you are.
What really stood out for me was the multi-person detection. When guests came over, I could actually see how the device tracked each person separately. It felt futuristic but practical — especially imagining its value for elder care, where subtle presence tracking is essential. The live tracking map gave a clear sense of where people were in the room at any given time. The built-in light sensor added another layer of intelligence. Instead of relying solely on motion, the system also considered room brightness, which meant no more lights turning on in daylight unnecessarily. And with the IR blaster, I was able to ditch several remotes — my AC, TV, and even a fan were easily programmed and controllable right from the app or through Google Assistant. What sealed the deal for me, though, was how smoothly it integrated with Home Assistant using MQTT. It exposed a rich set of data — not just presence, but zone-based detections, brightness, and even headcounts. Within minutes, I had advanced automations running locally with no delay or cloud dependency. It’s clear that this device isn’t just a motion sensor — it’s the brain of a truly intelligent room.
Integration is where the eMotion Max really shines — it’s not just a standalone presence sensor; it’s designed to be the backbone of a responsive, automated environment. For anyone serious about smart home control, its support for MQTT, Home Assistant, and Modbus TCP is a game-changer.
Starting with MQTT, this lightweight messaging protocol is the gold standard for fast, reliable communication between smart devices. eMotion Max uses MQTT natively, meaning it sends real-time updates directly to your smart home system without delay. Whether you’re tracking someone entering a room or adjusting automation based on zone occupancy, you get instant, precise feedback — no cloud, no lag. That local control also means better security and reliability.
With Home Assistant, the integration is seamless. The eMotion Max exposes a rich set of entities — including detailed zone data, light levels, headcount, and presence state — all ready to be used in automations. For example, I was able to create custom scripts like “if someone is detected in the sofa zone and brightness is low, turn on the ambient lights.” You’re not limited to simple on/off logic; you can build nuanced, room-aware behavior tailored to how you actually live.
Then there’s Modbus TCP, which may not be as familiar to the average smart home user but is essential for industrial and commercial environments. It allows the eMotion Max to plug into larger building automation systems used in offices, factories, and hotels — places where reliability, standardization, and scalability are key. With Modbus TCP, facility managers can use the same presence data to optimize energy use, HVAC control, or security across entire buildings.
In short, these integrations make the eMotion Max more than just a smart sensor — they make it a versatile platform that fits equally well in a personal smart home, a sophisticated DIY setup, or a large-scale commercial building. It adapts to your system, not the other way around.
One small but important tip from my experience: make sure to update the firmware right away before you start testing the eMotion Max. I initially skipped this step and noticed that some of the advanced features weren’t behaving as expected. Once I installed the latest firmware update through the app, everything clicked into place — responsiveness improved, the zone detection became sharper, and the integration with Home Assistant was flawless. Also, don’t forget to clear the app cache after the firmware update. It may seem like a minor step, but it made a noticeable difference in syncing the latest settings and ensuring smooth operation. It’s a quick fix that saves you from unnecessary head-scratching later — something I learned the hard way during my setup.
Whether you’re looking to improve automation accuracy, reduce false triggers, or monitor occupancy non-intrusively, the eMotion Max delivers exceptional value and versatility. Highly recommended for any serious smart home setup.
LinknLink eMotion Max Main Features
– Stationary Human Detection. Say goodbye to waving at outdated PIR motion sensors! Powered by advanced millimeter-wave radar, eMotion Max detects even the slightest movements — like your heartbeat or breathing — while you’re sitting still or sleeping. Customizable delay settings help maintain accurate presence detection and prevent false triggers.
– Multi-Zone Positioning & Smart Automations. No need for multiple sensors! With up to 4 customizable detection zones (e.g., sofa, bed, desk), simply tap and draw on a 100-grid map within the app. Set personalized automation rules for each zone with precision and ease.
– Multi-Person Counting & Live Tracking. No cameras. No privacy concerns. eMotion Max detects and tracks up to 4 people in real-time, identifying their locations within the detection range. Ideal for hotels or Airbnb hosts to monitor and limit guest numbers without compromising privacy.
– Advanced Elderly Care Monitoring. Support independent living with smart elderly care. eMotion Max detects unusual inactivity and triggers alerts if no movement is sensed within a set time. It also syncs live positions to the cloud and uses AI to analyze movement patterns, helping assess well-being and provide families with timely care insights.
– Seamless Home Assistant Integration. eMotion series devices work entirely locally after setup. Built-in MQTT support allows for instant integration with Home Assistant and other third-party platforms. Enjoy real-time zone updates and ultra-fast, local automations—plus full compatibility with Alexa, Google Assistant, and Siri.
– IR Blaster & Ambient Light Sensor. The built-in 360° IR blaster supports universal control of TVs, air conditioners, audio systems, and more, with a range of up to 15m (49ft). The integrated light sensor detects ambient brightness and works with presence detection to automate lighting when the room is dark and occupied.
– Superior Anti-Interference Accuracy. eMotion Max intelligently filters out non-human movement in 3D space. Define interference zones in the app to exclude items like plants, curtains, or pets, and set a filtering height to ignore fan movement or crawling pets—ensuring accurate human presence detection every time. Note: eMotion Max requires a certified 5V/2A power adapter. Please refer to the “Installation Guide” in the App for setup instructions.
