Shelly Presence Gen4 White - Intelligent Presence Sensor, mmWave Technology, Wi-Fi & Bluetooth, Light & Humidity Sensor

TheShelly Presence Gen4 White represents the pinnacle in human motion and presence detection, utilising advanced mmWave radar technology (5.8 GHz). Unlike traditional PIR sensors that only detect broad motion, Shelly Presence can detect "static presence" - a person sitting still on the couch, reading or sleeping. Equipped with new 4th Generation hardware, this device offers incredible accuracy, eliminating unpleasant situations where the lights accidentally go out while you're still in the room.

Key Benefits (Selling Points)

• Ultra-Precise mmWave Detection: The sensor can detect even micro-movements caused by breathing. It is the ideal solution for offices, bathrooms or living rooms, where traditional sensors often fail to keep the lights on.

• Built-in Ambient Light Sensor (LUX): Monitors the light level in the room to provide intelligent automation. You can set the lights to switch on only if presence is detected and natural light is insufficient.

• Temperature and Humidity Monitoring: In addition to presence, the device monitors the room's microclimate, allowing you to automatically control ventilation or air conditioning for optimal comfort.

• Configurable Detection Zones: Allows you to define specific monitoring zones and set the detection distance (up to 5-7 metres), ignoring movements outside the area of interest (such as passers-by in the hallway).

• Powerful Gen4 Hardware: The new generation brings a faster processor, expanded memory for complex local scripts and more stable and secure Wi-Fi/Bluetooth connectivity.

• Minimalist White Design: The sleek, compact white casing discreetly blends unobtrusively into any ceiling or wall, making it almost invisible in your interior decor.

Examples of Smart Automation

1. Office Efficient: The lights stay on as long as you're at your desk, even if you're typing or on a video call without moving around a lot. They switch off as soon as you leave the room, saving energy.

2. Bathroom Comfort: No more lights going out while you're in the shower. Shelly Presence detects your presence through the glass screens and keeps the system active.

3. Climate Control: If the humidity rises above a certain threshold and presence is detected in the room, the sensor can command a Shelly Plus 1 to turn on the exhaust fan.
