I rejected wireless intercoms at the time because every wireless thing I bought had horrible sound quality, like the worst walkie-talkie. Even with simple analog electronics, wired had good sound quality.

I did install some speaker wires, but the times when I wanted to play music in one room and hear it in another are just about never.

Guess I'm just not finding any point to home automation. Even if I had installed a home automation system, the intervening years would have turned it into expensive obsolete junk anyway. I've heard of people, when they try to sell their homes, having to rip it all out and put in conventional wiring.

What did pay off was running Cat5 and RG6 cables in a star configuration. Wifi has improved greatly, but it's nothing like a wired connection for smooth, problem free operation.

I have speakers around my house, including on my deck, wired to a stereo receiver for music and I do use it. But Sonos didn't exist when I had the various renovations done when the wiring was added. If I were doing it today, I'd almost certainly just go with some sort of wireless system.
