Smart home adoption in the U.S. rose from 30% of internet users in 2016 to 40% of adults in 2021. The impact goes beyond convenience, with smart thermostats cutting residential heating energy use by 4% to 11% and smart lighting controls reducing lighting energy use by 20% to 60%. The risks are rising too, as NIST found that common device misconfiguration can expand smart home attack surface by about 10 times.
