Smart home technology allows homes to be automated through the use of devices that can be controlled remotely or programmed to perform tasks automatically. Sensors can monitor conditions like temperature and humidity, while devices like smart locks, lights and thermostats can be controlled from a phone app. Challenges include security issues if devices are hacked, compatibility problems between different brands, and over-reliance on technology that may fail. However, future advances may lead to increased automation through artificial intelligence, seamless integration of all devices, and greater energy efficiency in homes.
