The Inovelli Red Series mmWave Presence Dimmer (VZW32-SN) is a Z-Wave 800 in-wall dimmer with a built-in millimeter-wave presence sensor and a lux sensor. It dims wired lighting and reports occupancy and ambient light locally over Z-Wave JS.

Roles it can fill
The mmWave sensor detects true presence even when occupants are still, while the built-in lux reading can hold lights off in daylight. No neutral required when a bypass is fitted; it carries the RGB notification LED bar and multi-tap scene control and is fully local over Z-Wave JS.
Events and automation triggers
Presses on this device reach Home Assistant as device triggers through
the
Z-Wave
integration, which you pick in the automation editor after pairing.
The button list, and whether each button also becomes an
event
entity, comes from what the device reports at pairing time, so it
appears once the device is on the network.
Read from Home Assistant 2026.8.3: the integration declares these trigger types, and core holds no per-model button list for this device.
