For almost anything in your home today, there’s likely a smart version of it. However, a few major categories are gaining traction. One of these is safety and security, which includes smart locks, doorbells, alarms, window sensors and surveillance cameras. Another major category is lighting and power, which includes smart lighting, power strips and thermostats. Other popular devices include smart appliances (refrigerators, dishwashers and water heaters), home entertainment technology and smart home hubs. These can be used to control and automate your smart home devices through voice commands or an app.
