What receiver are you planning to use? For example some people have had issues turning on marantz via IP so that's better done Serial, then integra IP, then some revivers don't have driver so need to be IR
You can add multiple instances of any driver to allow control of multiple of the same device.
If you feel like you're in over your head a little bit shoot me an email,
[email protected] as a dealer I'd be happy to help
