My understanding is it gives them an IPv6 address, but that does not mean they have internet access unless there is a hub that connects between the two. There's no WiFi, they use Zigbee behind the scenes, what changed is that they are addressed via IP, but it's still a strictly local network.

> There's no WiFi > Matter uses Bluetooth Low Energy for provisioning via a QR code, while it relies on Wi-Fi for high-data rate connectivity and Thread for low-data-rate communications. So you say no WiFi but the post specific says WiFi. And if there's wifi then I have to set up my network to ensure they don't have internet access, thats not something Im going to leave up to the honor system.

  The WiFi is in the hub. You should read it more carefully.

    Yes. it says "Wi-Fi for high-data rate connectivity and Thread for low-data-rate communications" Wi-Fi in the hub but not in the devices would make no sense. Why have Wi-Fi in the hub if devices aren't going to use Wi-Fi to connect to it? Also I went back, and searched the post for Wi-Fi, and the thing I quoted is the only reference to Wi-Fi. It uses Wi-Fi for high data rate connectivity. IE, a camera transferring data to the hub. so the camera has wifi. You can't transmit data over Thread, it's not high bandwidth enough. No where in the linked post, though, or in the source press release does it mention that Wi-Fi is optional, but other more informed users here have said that it is optional, and only necessary for high bandwidth stuff like cameras, so lightswitches could be Thread only. So some devices apparently won't have it. But many will. Reading the actual CSA press release, it says > Wi-Fi enables Matter devices to interact over a high-bandwidth local network and allows smart home devices to communicate with the cloud. So yes. The goal for the Wi-Fi is both to transmit high bandwidth stuff like camera feeds over local network, but also to allow "smart devices to communicate with the cloud" aka "reach the internet". So yes, the devices _will_ have WiFi. You should read it more carefully.

Thread and Zigbee are entirely distinct protocols; Matter does not use Zigbee in any way, at any layer of the stack, with the exception of some influence on the high-layer device/data modeling
