Actually, if you install the Bluetooth binding it all works again.
I’ve recently merged a preliminary Bluetooth proxy that allows your ESPHome device to also work as a proxy to other Bluetooth devices. For now only one way support works meaning devices that broadcast data can be picked up. I’ve tested this with GitHub - rbaron/b-parasite: 🌱💧 An open source DIY soil moisture sensor devices and a Shelly BLU button - they all send BTHome protocol data. BTHome data is supported by the openHAB BTHome binding.
I simply forgot at about this dependency when I merged this 6 month old PR, but I’ll try to find a way to mark the Bluetooth binding as an optional bundle/feature dependency. If any of you knows how to do this I’m happy for any hints
