Cannot add Bluetooth integration while having functional ESP32 Bluetooth proxy

… is this an issue? I have devices connected via ESP32 Bluetooth Proxy, but because of the mighty Microsoft HyperV I my actual OS doesn’t have a bluetooth device. Is seems silly I cannot add bluetooth integration, but yet again I don’t really know what it offers. And yet again, it seems like most of my bluetooth devices are not getting found. If all is good and logical, maybe this just needs an explinatory popup, or maybe all is not good?

Tell me I’m an idiot and shouldn’t concern myself with things above my pay and I’m happy.

You don’t need the bluetooth integration to use proxies. That one is for a bluetooth adapter hooked to your HA machine, somehow.

Why your devices are not found is another story.
What are they?
Are you positive they are supported by HA?
