Shelly has detailed its upcoming Presence Gen4 sensor, a mmWave-based device designed to detect occupancy more accurately than traditional motion sensors, including when occupants remain largely still. The device is part of Shelly’s wider Gen4 range, which is positioned around broader protocol support, including Matter for integration with platforms such as Apple Home.
Unlike PIR-based sensors that rely on movement, Presence Gen4 uses mmWave radar to continuously track presence within a space. Shelly states the sensor can monitor areas of up to 42 sq m, while supporting up to 10 configurable detection zones. However, we’ve yet to confirm if these 10 separate zones are exposed separately in Apple Home, or other platforms for that matter. It’s…
