My Russound AV controller uses TCP over IP (or RS232). I want to use Hubitat/webcore to send commands to the Russound. Can I do that?
Hubitat does expose a RAW Socket interface that may be able to be the basis for your new driver...

Unfortunately, I do not know the first thing about writing a driver.
