Shelly Presence Gen4

The Shelly Presence Gen4 detects real presence - even without movement - tracking up to 6 people in 10 zones for accurate, reliable automation. Prevents false triggers, cuts energy waste, and integrates easily with smart lighting, HVAC, and home systems.

Shelly Presence Gen4 brings next-level precision to your smart automations, with multi-protocol connectivity including Wi-Fi, Zigbee and Bluetooth (and Matter certified). Using advanced radar technology, it can detect even the slightest human presence - whether someone is actively moving or simply sitting still.

With multi-person tracking, zone-based sensing, and smooth integration into your smart home ecosystem (including Home Assistant), it's the perfect upgrade for lighting, HVAC, and energy-saving scenarios.

The Presence Gen4 includes adjustable sensitivity and a built-in light sensor to further tweak and support automations, and is powered via USB-C (5V 1A). A USB-C cable is included.

Available in white or black - please select an option before adding to cart.
