We buy technology for the convenience it gets us. When we can't rely on technology doing what it promised for us then we complain because we spent money on something that doesn't work as advertised. Even worse when it did work before and no longer does.

In any case, OPs reasons for wanting to turn off any light in any of their rooms are unknown to us.

Maybe they took their kids out to breakfast and realized they forgot to turn the lights off while they were driving. Good thing they bought those smart lights that can be controlled with siri! Oh no! It doesn't work the way it was advertised!

There's no reason to imply OP is a bad parent just because they want to turn off a light remotely.
