Why eMotion Air converts organic shoppers
eMotion Air is a battery-powered mmWave presence sensor for rooms where wiring is hard but reliable occupancy automation still matters. It helps Home Assistant users keep lights, climate, and routines responsive when people are sitting still, not just walking past a PIR sensor.
- Battery-powered placement: test presence automation in bedrooms, offices, and rental rooms without opening walls.
- mmWave presence detection: detect subtle occupancy for scenes where motion sensors often turn off too early.
- Home Assistant room automation: use presence data to coordinate lights, comfort, and energy-saving routines.

Proven Professional mmWave Presence Sensor Supplier
As a truly innovative smart home solution provider, LinknLink has taken a different path from day one. Unlike traditional smart home companies, we focus exclusively on two core product categories: smart gateways and presence sensors.
From the very beginning, we moved away from conventional PIR technology. Over the past three years, we have successfully developed multiple generations of our eMotion product line — starting with the first-generation 5.8 GHz eMotion, followed by the 24 GHz eMotion Pro, and advancing to our high-end 60 GHz eMotion Max and eMotion Ultra. These products have received broad recognition and positive feedback from the market.
The technology and expertise we have accumulated in mmWave presence sensing are proven, reliable, and truly differentiated. You can trust not only our technical foundation, but also the strong validation from real-world users and numerous smart home influencers who have reviewed and recommended our products.
Frequently Asked Questions
Does eMotion Air detect a person who is sitting still?
Yes. eMotion Air uses 24GHz mmWave radar to detect subtle micro-movements, so it can keep automations active when someone is sitting on a sofa, working at a desk, or staying still in a room.
What is the difference between eMotion Air and a PIR motion sensor?
A PIR sensor mainly reacts to larger motion and heat changes. eMotion Air is designed for presence sensing, so it can support more reliable lighting, comfort, and energy-saving automations when movement is minimal.
Can eMotion Air work with Home Assistant?
Yes. eMotion Air is positioned for Home Assistant users who want local access to presence, climate, light, and button entities for faster and more private automations.
Does eMotion Air need wiring?
No. eMotion Air uses 3xAAA batteries and supports magnetic, adhesive, screw, corner, and tabletop mounting, making it suitable for renters and rooms where wiring is not convenient.
Can eMotion Air trigger Alexa or Google Home routines?
Yes. eMotion Air can connect with Alexa or Google Home for presence-based triggers and voice status checks. Temperature and humidity automations may be limited by the platform.
Is eMotion Air privacy-friendly?
Yes. eMotion Air is not a camera. It uses sensor data for presence, light, temperature, humidity, and button actions instead of recording visual images.
