Shelly Presence Gen4 – mmWave presence and light sensor
Shelly Presence Gen4 – mmWave presence and light sensor is a revolutionary smart sensor that uses advanced radar technology (mmWave) to solve the biggest drawback of traditional PIR motion sensors. It is capable of detecting breathing and micro-movements, meaning it knows exactly when you are in a room, even if you are sitting perfectly still or sleeping. With support for Wi-Fi 6, Bluetooth 5, Zigbee 3.0, and Matter, it represents a superior multi-protocol hub for seamless automation of any modern smart home.
Main features
-
True presence detection (mmWave): The sensor does not just detect motion; it uses a 60-64 GHz radar to monitor your actual presence in the room. This prevents annoying automatic light shut-offs while reading or watching TV.
-
Multi-person tracking and zonal detection: It can track up to 6 people simultaneously and allows for the setup of up to 10 customizable zones within a room (up to 42 m²). This enables turning on specific lights only in the part of the room where someone is actually located.
-
Built-in light sensor: Contains an ambient light sensor that distinguishes between dark, twilight, and bright light. This allows you to create scenarios where lights only turn on when it is dark enough.
-
Full multi-protocol support: Equipped with an ESP-Shelly-C68F (Gen4) processor and natively supports Wi-Fi 6, Bluetooth 5 LE, Zigbee 3.0, and Matter-over-Wi-Fi. The sensor can also act simultaneously as a Wi-Fi range extender and a BLE gateway for other devices.
-
Advanced filtering ("pet-friendly"): With advanced sensitivity settings, the sensor can ignore floor-level movements, preventing false triggers caused by pets or robot vacuum cleaners.
-
Local control and privacy: It detects people completely without the use of cameras, ensuring privacy. The device supports local scripting, webhooks, and MQTT, allowing your automations to run instantly and reliably even without an internet connection.
