Is your feature request related to a problem? Please describe.

I use the Batmon HA integration to connect my two Supervolt batteries to HA. The Bluetooth connection with my RPI 3 is running but stopped after short or long time. The RPI 3 does have a high CPU load and is not able to build ESPHome firmware files. The Bluetooth connection with my RPI 4 is very bad and I got not a connection. My RPI 4 is placed in a metallic case with passive cooling. I would like to use a Bluetooth Proxy to connect the RPI 4.

Describe the solution you'd like

Please add the Supervolt BMS from Batmon HA in your integration. I will perform the test of this connection with my both batteries. I have a description of the communication protocol. see attachments.
