ESPHome has this feature (called btproxy). It works well with BTLE devices. I use it for remote temperature sensors and a few other IoT btle devices.

This seems to be specific to Home Assistant:

> Note that while this component is named bluetooth_proxy, only BLE devices (and their Home Assistant integrations) are supported.

One specific use-case I have in mind is controlling a Chromecast over the internet. So a smartphone should have its bluetooth signal relayed over an IP network. I haven’t found anything that would allow me to do that yet.
