Hello, thank you for this excellent Home Assistant addon. I use the Xantech MRAUDIO8X8.
I wanted to share with the community that I was able to get it working over ethernet for the last two years using these two devices:
Ethernet to serial converter: Amazon.com: USR-TCP232-302 Tiny Size RS232 to TCP IP Converter Serial RS232 to Ethernet Server Module Ethernet Converter Support DHCP/DNS : Electronics
Serial cable: Amazon.com: DTECH 5ft RS232 Null Modem Cable DB9 Serial Male to Male Cord Full Handshaking 7 Wire Crossover for Data Communication Compatible with Computer Network Switch Router (5 Feet, Black) : Electronics
and using this in the port configuration: socket://192.168.1.x:8234/
The x is set based on your static or DHCP address for the serial to USB converter and port number based on your configured port on the converter.
I have seen before other people mention having the control for balance, base and treble on these amplifiers. Are there any plans to add this even as attributes in Home Assistant to the standard integration if it is difficult to add it to the standard media player card?
