The LinknLink Emotion Pro utilizes 24GHz Microwave Doppler Radar to detect human presence, including the micro-movements associated with stationary occupants. Technical analysis reveals a Wi-Fi-based communication architecture that eliminates the need for Zigbee or Z-Wave hubs. The internal chipset is optimized for local polling, facilitating integration with Home Assistant via the Tuya Local protocol. Material specifications indicate a required constant USB power source, as the active radar module exceeds the power density provided by standard battery configurations.
Aggregated data confirms that the 24GHz radar waves are capable of penetrating low-density materials; as such, software-defined sensitivity and distance thresholds are provided to mitigate false triggers from external movement. The device's performance is optimized for environments where PIR sensors would fail to maintain an "Occupied" state, such as offices, bedrooms, or seating areas. Operational reliability is enhanced through the assignment of static IP addresses to prevent disconnection during DHCP lease renewals.
- Static Presence Detection: Maintains active triggers during sleep or sedentary work.
- Hub-Free Integration: Connects directly to local 2.4GHz Wi-Fi networks.
- Adjustable Detection Radius: Allows for fine-tuning of the radar field to fit specific room dimensions.
While the hardware is part of the Tuya/Smart Life ODM ecosystem, the firmware is specifically calibrated for presence-sensing stability. It serves as a middle-tier solution for users requiring more than basic PIR motion sensing without the complexity of 60GHz spatial mapping systems.
If your automation strategy requires native Matter support without the use of a software bridge, the Meross 3-in-1 Smart Sensor provides an alternative Wi-Fi presence solution with broader cross-platform certification.
This device is an essential component of the motion and presence sensors class, focused on Wi-Fi-based presence detection.
