It sounds like each room (zone) has (2) sets of speaker cable and there is a passive volume control inline. If that is the case then I believe https://www.monoprice.com/product?p_id=10761 could work.
The unit does have zone control panels but if you are using RS232 i dont believe you need it connected. you would need Ethernet to RS232 adapter https://smile.amazon.com/gp/product/B01GPGPEBM/. I was able to integrated it into HomeAssistant and Hubitat (what i have done).
I do not have it integrated w/ a voice assistant. But do have control over input, volume control for each zone via home assistant or Hubitats webui.
