ZHA: VZM32-SN mmWave entities unavailable and no FC32 reports received

[ToTheLastByte]

Environment

• Home Assistant OS: 17.3
• Home Assistant Core: 2026.5.4
• Supervisor: 2026.05.1
• Frontend: 20260429.4
• mmWave Visualizer Addon: 3.2.4
• Device: Inovelli VZM32-SN
• Zigbee Stack: ZHA
• Custom quirk installed per documentation

Issue Summary

After replacing the official Inovelli ZHA quirk with the modified mmWave Visualizer quirk (__init__.py and VZM32SN.py), the VZM32-SN is discovered successfully by the addon, but no mmWave data is ever received.

The addon reports:

ZHA: discovered Master Bathroom Lights (0c:2a:6f:ff:fe:f3:de:b2)
ZHA: monitoring 0c:2a:6f:ff:fe:f3:de:b2
ZHA: WARNING — no data received from 0c:2a:6f:ff:fe:f3:de:b2 after 10s. Cluster 0xFC32 binding may be missing.

No mmWave events are received by the addon and the visualizer never populates.

Important Observation

When using the stock Inovelli VZM32SN.py quirk:

• All mmWave entities are available and readable.
• The switch functions normally.

When replacing it with the Visualizer-modified quirk:

• All mmWave entities become unavailable.
• No mmWave reports are received.
• Visualizer receives no data.

This suggests the problem is specific to the modified Visualizer quirk rather than the switch, firmware, or ZHA itself.

Device Discovery

Addon debug output:

ZHA: Connected to Home Assistant WebSocket API successfully.

ZHA Events

Button events are received correctly:

event_type: zha_event
data:
  device_ieee: 0c:2a:6f:ff:fe:f3:de:b2
  endpoint_id: 2
  cluster_id: 6
  command: "off"

However:

• No mmwave_anyone_in_area
• No mmwave_target_info
• No other mmWave-related events

are ever emitted.

Cluster Verification

The custom clusters are present in ZHA:

InovelliVZM32SNCluster (0xFC31)
InovelliVZM32SNMMWaveCluster (0xFC32)

So the custom quirk appears to load successfully.

Bindings

In the ZHA Bindings page:

• FC31 appears
• Standard clusters appear
• FC32 does NOT appear

This seems consistent with the addon's warning:

Cluster 0xFC32 binding may be missing

Entity State

All FC32/mmWave entities exist but remain unavailable:

Examples:

number.master_bathroom_lights_mmwave_depth_maximum_far
unavailable

number.master_bathroom_lights_mmwave_hold_time
unavailable

number.master_bathroom_lights_mmwave_width_minimum_left
unavailable

select.master_bathroom_lights_mmwave_sensitivity
unavailable

Every FC32-backed entity shows:

restored: true

indicating the entities were created but values were never successfully read from the device. I believe these were originally created by the Inovelli stock py files.
