Which Bluetooth Proxy is my device using?

I have a HomeAssistant setup with multiple bluetooth devices and proxies. How can I tell which proxy my device is using?

More generally is there anything that explains how the BT Proxies communicate? Does HA connect to the proxy and pull the BT data? Or does the proxy push the data to Home Assistant?

Enable debug logs for homeassistant.components.bluetooth. It will be shown in the log.


Well that was a journey!

Seems to work - but begs some questions about why this is so arcane! Iā€™d have though the proxy could have been part of the entity or something. [Another WTH question perhaps?]

Is there a guide to how the BLE Proxies work anywhere?
