Home automation adoption has jumped fast, yet the bigger surprise is how much impact those devices can have on both energy use and security risk. In 2019, 19.2% of U.S. households already had at least one smart home device, but study after study shows the real gains come from smarter control, not just added hardware. Alongside that progress, NIST estimates networked device misconfiguration can increase attack surface by about ten times, making this industry’s growth as much a cyber challenge as it is a convenience story.
Key Takeaways
- 3 in 10 U.S. internet users (30%) reported owning a smart home device in 2016
- ~4 in 10 U.S. internet users (41%) reported owning a smart home device in 2018
- ~4 in 10 U.S. adults (40%) owned a smart home device in 2021
- Smart thermostats are forecast to reach 150 million units shipped in 2027 (IDC)
- A 2023 EPRI study found that smart thermostat deployment can reduce residential space heating energy use by 4%–11% (average across scenarios)
- A 2014 peer-reviewed study reported smart thermostats reduce heating energy consumption by 10% on average
- A 2020 peer-reviewed study found smart lighting controls can reduce lighting energy use by 20%–60% depending on occupancy and control strategy
- Average cost of a basic smart thermostat installation is ~$200–$300 in the U.S. (Angi)
- Average cost of smart door lock installation is ~$250–$400 in the U.S. (Angi)
- Average cost of smart security system installation is ~$1,200 in the U.S. (HomeAdvisor report via Angi)
- The global smart lighting market is expected to grow at a 14.9% CAGR from 2024 to 2032
- The global smart home security market is forecast to reach $26.2 billion by 2029
- U.S. residential buildings have on average 102 million square feet of ceiling area cooled by HVAC systems
- In 2023, ransomware and extortion were the leading cybercrime threat types targeting organizations, accounting for 18% of cases in one global dataset
Smart thermostats and other connected devices are rapidly spreading and can cut energy use, while cybersecurity risks grow with networked misconfiguration.
