Switchbot Air Purifier Matter over WiFi is failing

Configuration Matter/Thread
1

I want to connect my Switchbot Air Purifier via Matter over Wi-Fi with my Home Assistant (2025.10.2) but it is failing because the device is not trustworthy.

Pairing failing video

I can see this in the logs.

I could successfully connect my Meross MS315 via Matter over WiFi.

Can someone support me please.

Similar to me. It’s connected already to Apple Home and I used the option to activate the pairing mode and then the provided code to add it to HA.
With other devices (EVE plugs and sensors) this worked instantly, however with the Switchbot Air Purifier it fails to connect it to HA with the provided code. It did not work as well to directly use the matter code provided on the device.
