You Can Already Control Your Smart Home
By connecting to iCloud, you can turn your Apple TV into a smart home hub to control your HomeKit devices. While this is a nice feature, it’s really not worth buying an Apple TV. For one, not all of your smart devices may be compatible with HomeKit (although it’s worth checking to see).
Also, many other different devices can function as a smart home controller, including an Amazon Echo speaker (which includes voice command technology) and even the iPhone you already own. You could even choose a smart display like the Lenovo Smart Display or Echo Show 2, which add their own touchscreens that can help you better control your smart home. The Apple TV just doesn’t have as much to offer here..
