Can I have 2 sets of (PlayBars+Sub) for 2 sets of TV at home?

Yes absolutely no problem.

And I do, actually. One full set in the living room, one full set in the bedroom.

You can have up to 16 paired play bar+subs on the same Sonos system - your only limit is the 32 device max limit of Sonos.

To be really pedantic, I THINK the 32 limit includes controllers

It doesn't. 🙂 You can have 32 targets and 32 IP controllers.

Actually I think you are right. I stand corrected.

With most people's network setups, of course, 32 is probably the combined limit if they're lucky, but with good design, Sonos put in an artificial 32 cap on each - based on the ability to stream 32 FLAC streams at once, if memory serves from the rep, those many years ago.
