STATIONARY HUMAN DETECTION & ANTI-INTERFERENCE – Say goodbye to waving at outdated PIR motion sensors! Powered by advanced mmWave radar, eMotion Ultra detects even the slightest movements — like your heartbeat or breathing (facing front) — while you’re sitting still or sleeping. Define in-app interference zones to exclude plants, curtains, or pets. Set a filtering height to ignore fan or pet movement.
MULTI-ZONE POSITIONING & LIVE TRACKING – No need for multiple sensors! Simply tap and draw max 4 customizable detection zones (e.g., sofa, bed, desk) in LinknLink App and set personalized automation rules for each zone in app or Alexa/Google routines. eMotion Ultra detects and tracks up to 4 people in real-time, identifying their locations within the detection range without compromising privacy.
HOME ASSISTANT, ALEXA, GOOGLE HOME – eMotion Ultra operates entirely locally for instant integration with Home Assistant and other MQTT-supported platforms, making all entities (zones, brightness, temperature, humidity, etc.) available. With an internet connection, it also supports Alexa, Google Home, and Siri for third-party control and automations.
IR BLASTER, BRIGHTNESS, TEMPERATURE & HUMIDITY – 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 and on-cable temperature humidity sensor detect ambient environmental changes. These sensors collaborate with presence detection to enable complex automation, reducing or eliminating the need for additional sensors.
ALERT NOTIFICATIONS & CLOUD DATA EXPORT – Get real-time notifications directly to your phone whenever there’s a change in status whether it’s presence, brightness, temperature, or humidity, even if the app isn’t open. Your data is securely kept on the cloud with a comprehensive 3-year trackable history and can be downloaded in standard CSV format for analysis or other purposes.
BLE HUB FOR EXTENDED ACCESSORIES – Connect and manage more devices with eMotion Ultra, which acts as a dedicated BLE hub for a wide range of LinknLink BLE accessories: Contact sensors, Temperature and humidity sensors, Fingerbots, Curtain openers and Door locks. Supports max 20 BLE accessories and sync them with Home Assistant via MQTT.
DOUBLE-SIDED MAGNETIC INSTALLATION – Improved foldable and adjustable stand features double-sided magnets for flexible installation options: Desktop placing, Wall mounting or Magnetic attaching. IMPORTANT NOTICE: Requires a certified 5V/2A power adapter. Refer to “Installation Guide” in app for setup instructions. Max detection range: 6m / 20ft (moving) and 4m / 13ft (stationary)
