I’ve created a device that can be connected to my (and more) Rotel A12 amplifier so that i can control the amplifier and read info from Home Assistant.

It’s based on an ESP32-C3 super mini and a Max3232 Rs232 to TTL converter:

I used esphome as software on the ESP32.

These are the controls and the sensors that are made available:

Thanks for the share, did something quite similar but using some Kincony card that had RS-232 interface all built to control some serial devices :wink:
