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).

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.
