Matter uses a combination of Ethernet, Thread (a low-power connectivity method for battery-powered devices), Wi-Fi, and Bluetooth Low Energy to setup and manage smart home devices. The goal of Matter is to create one shared ecosystem that works with all smart home devices and hubs — with any luck, the pain of shopping for Apple HomeKit-compatible devices or double-checking that a certain light bulb works with Alexa should become a distant memory.
Now that Matter has officially arrived, we should see the first certified devices and hubs show up soon. Google’s new Nest Wi-Fi Pro router, for example, promises to be a Matter hub once it goes through the required certification.
