I've had roomies that were in IT, and generally most things weren't "smart" appliances. I think the fanciest thing they had was a plex server. We all know how insecure the IoT is.

I've also had non-IT roomies and yeah, they were putting up surveillance cameras and shit and being super-creepy with monitoring.

I once very, very quietly tried to wash a dish at 1am in the kitchen (and most roomies conclude I'm a ninja as I'm generally extremely quiet to anyone who isn't hyper-aware of noises already), and my roommate charged out trying to find the water leak.

I realized later she had some sort of monitoring alert on the water heater that woke her up, and because the house was dark because I didn't want to wake anyone up with lights so her cameras were dark too, she went into a panic instead of using her common sense. I'd accidentally evaded half her surveillance trying to be a considerate roomie while I washed something quietly in the dark and she lost her frickin' mind.
