Use Your Older iPhone or iPad to Control Your Smart Home
Nowadays, it’s easier than ever to create a smart home. All you need is the right accessories and apps on your iPhone. You also don’t need to use your main iPhone or iPad to manage your home; you can use your older devices instead.
Since it’s an older device, you can leave it at home, allowing anyone to control features like lights or thermostats. They won’t need to bother you to change something, and you won’t waste battery life or storage space on apps you rarely use.
