Before setting up a smart home, make sure that your devices can communicate with each other through Bluetooth or WiFi. While companies are actively discussing the creation of a communications standard for all smart home devices, manufacturers (Apple, Amazon, Google and Samsung, among others) currently have their own platforms. When buying a new smart home device, you’ll need to make sure it works with the products you already own. Fortunately, there are compatibility guides that can help you select devices that will work together.
