The Inovelli Blue Series mmWave Presence Dimmer (VZM32-SN) is a Zigbee 3.0 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 ZHA or Zigbee2MQTT.

Roles it can fill
The mmWave sensor detects true presence even when occupants are still, so lights can hold on while a room is in use, and the built-in lux reading can gate them by daylight. No neutral required when a bypass is fitted; it carries the RGB notification LED bar and multi-tap scene control, and control is fully local.

Events and automation triggers
Presses on this device reach Home Assistant as device triggers through
the
Zigbee Home Automation
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.
