Use Your Old iPhone as a Smart Home Controller

Turning your home into a smart home can be a bit pricey, especially because of all the extra accessories you will need to buy. However, you won’t need to buy a smart home hub, at least not at first. You can use your iPhone instead.
By default, all your smart home accessories will connect seamlessly to your iPhone, which means you can control everything from your security cameras to your lights with just a couple of taps.
But what if you don’t want to carry your iPhone around to control your home? Well, you can leave your old iPhone in a place like the kitchen or the living room and use it specifically as a dedicated smart home controller.
