The Best Smart Home Devices in the UK for 2021

What is a Smart Home Device?

There are many different types of smart products and appliances including, TV’s, refrigerators, speakers, doorbells and home security, lighting and thermostats and many more. These products and appliances are connected to the internet so they can be controlled from apps on your phone or a voice command.

If you add a smart hub, which can connect to your smart home devices, then your smart products and appliances can communicate with each other. For instance, when your kids come home from school the lights turn on automatically and the door locks behind them or when you issue the command “Alexa it’s movie time” the lights will dim, and the TV will come on.
