Problem description:
When connecting the IKEA Starkvind air purifier table successfully through Home Assistant with the ZBT-1 Zigbee device, the PM2.5 sensor data stays unknown. What I have noticed is, that when I try to reconfigure it, then the PM25Cluster binding works but the measure_value attribute is marked as UNSUPPORTED_ATTRIBUTE.

HA Core version:
2025.3.4

Zigbee device:
Home Assistant Connect ZBT-1

Connected device:
IKEA Starkvind table with air purifier (article number: 805.019.51)
