Connect Shelly BLU Door/Window to HA via Atom lite bluetooth proxy

Hi have a Atom Lite module configured as BT proxy via ESPHome.
Setup via Ready-Made Projects — ESPHome

I bought several Shelly BLU Door/Window sensors that only communicate over bluetooth which I like to connect to via the Atom lite.

FYI: I do not own Shelly plus a device.

Is this possible and if so, how can I get these D/W sensor visble in home assistant?

Thanks

Yes, it is possible and you have to use BTHome integration.

Good day, did you manage to integrate the sensors in HA?
Can you share your experience?
Thank you

I only could manage to crreate the BT proxies, see screenshot.

I struggle how I can add the BLU sensor from here.
I tried to tripple click the BLU sensor but I don’t see it appear under new devices in HA.

Any tips?

When the sensor is detected by BT Proxy, HA will prompt you to configure it with BTHome integration.

I ordered one to test and can confirm it immediately appeared in HA via BT Home. It reports illuminance, rotation/angle, open/close, battery, packetid and signal strength.
