Blue Series mmWave Presence Sensing Dimmer • Advanced mmWave Configuration

Note: This article explains the advanced functionality of the mmWave sensor on the VZM32-SN Zigbee mmWave switch. Most users will likely only need to perform basic configuration described in this article: mmWave Switch Configuration Guide | Inovelli Help Center

This cluster enables configuration of detection, interference, stay, and Z-axis range zones, giving precise control over where the sensor should detect motion and where it should ignore movement.

For example, interference zones can be used to exclude regions such as moving fans, vents, or reflective surfaces that might otherwise cause false presence triggers.

Note: To get reports from this cluster you need to 1) Bind to EP1 Cluster 0xFC32, and 2) Enable "Target Info Report" Attribute 107. Take note, this will cause 0x01 Report Target Info reports up to every 1 second when a target is detected.

0x00 – Anyone In The Reporting Area

Purpose: Indicates presence detection across up to four predefined sub-areas.

Field	Data Type	Description
`area1`	`uint8`	`0x00` – No target `0x01` – Target present

`area3`	`uint8`	`0x00` – No target `0x01` – Target present
`area4`	`uint8`	`0x00` – No target `0x01` – Target present

0x01 – Report Target Info

Purpose: Reports real-time location and movement data of detected targets.

Client → Server Commands

0x00 – Control Instruction

Purpose: Sends control commands to manage mmWave module behavior.

Control ID	Action
`0x00`	Restore mmWave module to factory configuration
`0x01`	Auto-generate interference area
`0x02`	Obtain interference and detection regions
`0x03`	Clear interference areas
`0x04`	Reset detection areas
`0x05`	Clear stay areas

0x01 – Set Interference Area

Purpose: Manually defines the coordinates of an interference area, which is an ignored zone where targets are not reported as present.
Up to four zones (area_id 0–3) can be defined.

Field	Data Type	Description
`area_id`	`uint8`	Range: 0–3. The mmWave module can store up to four interference zones.
`x_min`	`int16`	Minimum X-coordinate (–600 to 600 cm)

Practical Example: Zone Configuration Flow

Initialization
Send Control ID = 0x00 to restore the mmWave module to factory defaults.
Configure Zones
- Use Set Interference Area (0x01) to define up to four ignored areas (e.g., near a fan or vent).
  - Targets inside these areas will not trigger presence.
  - The Auto-generate interference area command automatically configures area_id 0.
- Use Set Detection Area (0x02) to define up to four active detection zones.
  - The attributes 101-106 configure dection area_id 0.
- Use Set Stay Area (0x03) for areas where stationary presence (e.g., someone sitting) should be detected.
Verification
Send the Control ID = 0x02 command to query current interference and detection area configurations.
The sensor will respond with Report Interference Area and Report Detection Area messages.
Monitor Activity
Listen for Anyone In The Reporting Area (0x00) and Report Target Info (0x01) messages to receive real-time presence and target position data.

Summary

The VZM32-SN mmWave cluster (0xFC32) provides advanced configuration options for fine-tuning detection zones, excluding interference areas, and managing vertical range.
By leveraging these features, integrators can optimize detection accuracy, reduce false triggers, and tailor sensing behavior to complex room layouts.
