Shelly Presence Gen4 Advanced Motion & Presence Detector (White)

The Shelly Presence Gen4 offers all the benefits of a motion detector such as the Shelly BLU Motion, with a wide and varied range of further improvements; instead of just detecting and relaying motion, the Presence Gen4 can detect presence and movement in real-time, plotting them on a field with up to ten different detection zones - each with fully customisable automation possibilities. For example, if a room has multiple lighting areas, the Shelly Presence Gen4 can detect which zone is currently occupied, and can instruct a Shelly Dimmer Gen3 to raise or lower specific lights.

The Presence Gen4 can track up to six people in real-time, and can even detect continued presence even when still - for example, when sleeping or reading - meaning that lights won't deactivate if a person is present but not moving. It has a customisable sensitivity and can filter out smaller presences as required like pets or robot vacuums, and features an embedded light sensor with three different detectable lux levels.

Shelly's Presence Gen4 includes a stand to mount it on a desk, shelf or other flat surface, but this stand can be removed from the device to mount it on the wall, either with screws or with the included adhesive pad.
