What Is Smart Home Technology?

Smart home technology involves gadgets, devices, and home appliances with wireless connectivity. When connected to the home Wi-Fi internet network, they communicate with each other, a smart bridge, or a mobile phone app.

At the center of most smart homes is a smart hub. A smart hub could be a Zigbee/Z-Wave-based smart bridge, a smart speaker, or a mobile phone app. You need to connect any of these hubs to your home Wi-Fi. Home appliances like smart lights, smart coffee machines, smart thermostats, video doorbells, smart security cameras, smart door locks, and more will either connect directly to the home Wi-Fi or a central hub.
