This is my config for using an SDM630 via MBMD with Home Assistant.

I did some slight adjustments for the general public, but you probably need to adjust some more things:

1. Setup a proper MQTT user+pass and configure that in mbmd.yaml
2. Adjust the serial device name. I recommend the by-id variant over /dev/ttyUSBx, especially if you have multiple devices (for me it's the RS485 interface and the Zigbee controller)
3. Maybe adjust the serial device config (baudrate and comset)
4. My mbmd is reachable via mbmd.server.lan, you probably want to adjust that in the sdm630.yaml

What I recommend:

/* Melbus CDCHGR Emulator
 * Program that emulates the MELBUS communication from a CD-changer (CD-CHGR) in a Volvo V70 (HU-xxxx) to enable AUX-input through the 8-pin DIN-contact. 
 * This setup is using an Arduino Nano 5v clone
 * 
 * The HU enables the CD-CHGR in its source-menue after a successful initialization procedure is accomplished. 
 * The HU will remove the CD-CHGR everytime the car starts if it wont get an response from CD-CHGR (second init-procedure).
