I don't know - with the research they've done over the past few decades about circadian rhythm, I can see a lot of benefit from lighting that responds in both intensity and color to time and or motion. Likewise with HVAC. But neither of these needs the outside 'net.
Where I really see benefit from external communication would be mostly Boolean data such as whether the kids made it home from school, is there a break in the dog's underground fence line, is moisture pooling where it's not supposed to, or whether the CO/smoke detector has alerted. For information that goes in instead of out, I could also see a benefit for automatic storm shuttering when NOAA issues a severe thunderstorm warning and an automatic disabling of the sprinkler system if the county passes a watering moratorium (i.e. save me from fines if I'm absentminded and forget about turning it off).
Where's a better place for a discussion which may introduce truth and actual intellectual debate? Maybe someone there will point out a real conservative viewpoint such as Augustine's from around AD 400 which by using the text of the Bible alone came up with the conclusion that a strictly (simplistic) literal interpretation was impossible and also never intended. Augustine also pointed out that some of the greatest damage that can be done to the Church is by scientifically-ignorant believers who attempt to lecture scientific experts about how the experts are wrong in their views.
Unfortunately for Christians, and just about every other group ever organized with a human membership component, ignorance at the adult stage is usually manifest in a self reinforcing mindset and not one welcome to instruction.
