Can you use BLE proxy in addition to bluetooth dongle?

Hi There, I have a Broadcom based USB BT dongle that works well with HA and my newly setup Theengs add on. I also have quite a few 2nd gen Shelly devices spread around the house, and wondering if it’s possible to use their BT proxy (like HA does?).

Thanks!

Hello I’ve got a similar question. My BM2 battery monitor devices connected to my cars batteries report well to the OMG when in range. I’ve got a Shelly 4PM that I would like to use it’s proxy features to listen to the BM2 close to it then forward to OMG, is it possible ?
