Correct. Unlike zigbee and zwave Matter does not define a single communication technique.
It can be used with thread, or over a standard tco TCP IP network.
Typically, Matter devices will support either thread or WiFi, but there’s no definite distinction to Matter itself.
If you also want to use Matter over Thread devices, you will need a thread dongle. The ZBT-1 can do either thread OR zigbee but not both at once.
In fact, the biggest issue I see with Matter is that there’s no real easy way to tell if the device uses WiFi or thread.
There are a lot of Matter devices out there now, but only a few use the Thread protocol.
If I’m in the bedroom, I may want my ceiling lights on if someone is in there if it’s dark outside, but if my wife and I are in bed, then only turn on the baseboard lights, at 1% brightness when someone is still in bed. Presence sensors aren’t that fine grained, and I certainly don’t want to wake up my wife when this old fart gets up to go pee again. She’s grumpy when awakened. 🤣
