Description
Shelly Presence Gen4 is a presence sensor that uses mmWave radar to reliably detect people, even when they are sitting still. It enables more natural room automation by sensing actual presence rather than just motion.
It is designed for precise, room-aware automations with customizable detection behavior for both real rooms and open spaces. With up to 10 customized zones, you can tailor how the sensor reacts in different areas and fine-tune it to match your layout.
Shelly Presence Gen4 connects via Wi-Fi 6, Bluetooth 5 LE, and Zigbee 3.0, and it supports Matter-over-Wi-Fi. It integrates with Shelly Cloud, Home Assistant, and other popular platforms. You can also manage and monitor it through its own Embedded Web interface.
