“Smart” anything is something of a misnomer as the “smarts” are on some “cloudy” server far away.

That is just wrong, there are tons of smart devices without any cloud server whatsoever. I think Phillips Hue lights even works locally for the “I don’t know what technology is” crowd who can’t set their own control server up.

There are also the professional smart devices you might use if you wire up a whole building. KNX smart devices also fully support local installations.

Don’t listen to the ads that tell you that you need some Google or Amazon server dependant artificially stupid smart device.
