The only thing I'd need to make smart is my box fan, because once I fall asleep it would be better to turn it off, but I like falling asleep with it on, and I can't turn it off if I'm already asleep.

So I could make that a smart device.

But I got those outlet power adaptors with a mechanical switch timer that just turns the power off when the timer dial rotates. It's got a 24 hour dial and multiple pins, so I could put my fan on a schedule if I wanted.

Cost like $5, I've been using them since 1995. Easy to repair and replace.

If it ain't broke.
