There is a somewhat strangely named German brand that sells private IoT door / security cams. Forgot the name, sadly. They’re quite expensive though. My guess is they might sell private lightbulbs.
For home audio, Sonos is great. Their voice assistant is completely locally processed.

Are you joking about Sonos? They force you to have account with them to use speakers and you have to enable location sharing on your app to connect (!!). They know more about people than their parents do.

And yet they're one of the few (only?) smart speaker that does locally processed commands. You and everyone else downvoting me are unknowledgeable clowns.
