Very interesting that it has Thread too. I wonder if that will be a somewhat viable system in a decade. (Show me where I can buy a cheap Thread border gateway that isn't an Apple or Google voice assistant or whatever.)
The Aqara Hub M100 is a nice cheap Thread border router.
TLDR: privacy, security.
I mostly use Eve devices. My AppleTV serves as the hub and I keep it plugged into Ethernet. HomePods scattered about keep the mesh strong.
