Aqara in Homekit and HASS

Hey Guys,

I use my Aqara Hub directly with HomeKit. Its perfect for me. Now I want use one Aqara Windows Sensor for HASS to make my Gas Counter Smart.

But my HASS can´t find the Bridge.

In the past my HASS recognized the bridge. But I’m not sure if I already connected this to Homekit at that time. Is this a more common problem? Here in the forum I haven’t read anything specific.

Could somebody explain
