The LinknLink eMotion Ultra is a stylish, all-in-one smart sensor that combines motion, brightness, temperature, and humidity detection in a compact design, delivering accurate real-time data for automation, energy efficiency, and enhanced home security. Together with the LinknLink App, it provides an intuitive interface for monitoring, device management, firmware updates, and automation routines, ensuring seamless integration, remote control, and a secure smart home experience.

Arm eMotion Ultra before you leave home, and rest assured knowing it will monitor for any unauthorized activity. Should it detect a potential threat, it immediately sends alerts to your smartphone. You can even configure it to activate sound notifications through Amazon Echo or Google Home for an added layer of security and peace of mind.

Traditional PIR motion sensors will mark you as “not detected” if you’re sitting still, as they only sense changes in the heat radiated from subjects. This lack of accuracy often leads to incorrect automation triggers, with the sensors assuming you’ve left. Radar sensors, operating at 60GHz frequencies, can detect even the slightest movements – such as your breathing and heartbeat. Only these radar sensors can accurately determine if a space is truly occupied, preventing false triggers and ensuring reliable automation. The eMotion Ultra radar sensors surpass traditional PIR infrared motion sensors with its capability to cover up to 40 square meters (430 square feet) using just one device. eMotion Ultra can be configured with up to 4 zones (e.g., sofa, bed, or desktop) within 100 grids, enabling personalized automation for each zone. The maximum detection range is 7 meters (23 feet) in front. Please refer to the detection range illustration and testing video below for more detail

The eMotion Ultra can track the movements of up to four individuals when multiple people are active in the same space, allowing users to easily monitor the number of people in a room. This feature is especially useful for hotels or Airbnb accommodations, where it can be employed to monitor and limit the number of guests staying. It also provides you with a map of live motion tracks, so you’ll know roughly where people are in the room. The eMotion Ultra accurately filters out interference sources in a 3D space. Through its app, users can designate specific areas to exclude objects like plants and curtains, and set a filtering height to disregard non-target movements such as pets or fans. This significantly enhances the precision of human detection.

Same as other sensors from LinknLink, eMotion Ultra offers world’s longest FREE data storage for up to 3 years. You can view detailed data history after years and export full data to Excel file at any time for records tracking.

No third-party integration is required! Adding the device to Home Assistant has never been easier. Simply enter basic information in the LinknLink app, and it will be automatically discovered in Home Assistant via the MQTT service. Detection syncs instantly to Home Assistant, making it the ideal presence sensor for local automations. Every feature of the eMotion Ultra supports voice control through Alexa, Google Home, and Siri without the need for an additional hub. It’s compatible with products across various brands and categories, allowing users to fully customize their smart home automation. This provides the ultimate solution for smart home enthusiasts seeking seamless interoperability and control.

The LinknLink eMotion Ultra is more than just a presence sensor—it’s a smart home command center. With its precise mmWave radar detection, rich environmental sensing, and powerful integration capabilities, it outclasses traditional sensors and even replaces multiple standalone devices. For homeowners, smart home enthusiasts, and professionals looking to create intelligent, responsive environments, the eMotion Ultra is an indispensable addition. Ideal for: Smart home power users, Home Assistant enthusiasts, and anyone seeking accurate, flexible presence detection with deep automation potential.
