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.

Choose eMotion Air when you need a battery-powered mmWave sensor

eMotion Air is the easiest LinknLink presence sensor to place when a room needs accurate occupancy detection but wiring is hard. Use it for bedrooms, hallways, rentals, shelves, desks, or temporary smart home layouts where a compact battery-powered sensor is more practical than a wired device.

Battery-powered placementPlace it where presence detection is useful first, then refine automations after you see real room behavior.
Better stillness detection than PIRmmWave presence sensing helps keep lights or scenes active while someone is reading, working, or resting.
Good first mmWave sensorStart with one room before expanding into Pro, Ultra, or gateway-based Home Assistant scenes.
Need Best choice Why
Battery-powered, flexible placement eMotion Air Best for quick deployment, rentals, shelves, and rooms where cable routing is inconvenient.
Presence detection plus AC/TV IR control eMotion Pro Choose eMotion Pro if you need IR control in the same room.
Premium 60GHz tracking and multi-zone sensing eMotion Ultra Choose Ultra for higher precision and multi-sensor room control.
Recommended setup: start with eMotion Air in one high-impact room where lights turn off too early. After the automation works reliably, add eMotion Pro for rooms that need IR control or eMotion Ultra for premium 60GHz tracking.

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.
