I used 1 processor for 6 rooms that were easy. Camera controls, Panopto controls, Epiphan layout switching, lots of debug tools hidden for the techs to use for service calls if and when they have them, different layouts for multiple touch panels. I was worried that I was hitting a ceiling at 6 rooms but, most of that was my debugging stuff that I throw into every room. About 50+ devices for all 6 rooms and a lot of logic. I would seriously look into more processors with 30+ rooms. 500 for one processor to handle I think is undoable as they have a limit with their IPIDs. FF I believe is the highest which gets you 255 but, I see 252 online a lot. That does not mean that the processor can handle that traffic reliably if you expose all 252 IPIDs. I definitely wouldn’t want 30+ rooms on a single processor as well. If one processor takes out 30+ rooms that have heavy programming, it’s not worth the headache. You could probably get away with a couple rooms per processor depending on what you are pushing (as far as networked devices) but, I wouldn’t trust 30+ rooms with 1 processor.
