So what you’re saying is - every house is now a haunted security house.

I think that would be an amazing idea for something like an actual house or a gallery you could visit It would be full of IoT devices, full of reminders about firmware updates and letters introducing a subscription service, and none of these devices will work because of that

The real fright would come from whatever monster amalgamation manages to interoperate...

That is actually a pretty good twist to the classic trope.
