My only recommendation is that you should spend a little more money on specifically an evaporative humidifier. They’re a bit louder (I think I’ve got a Vornado EV100 or something?) but the cheap humidifiers on Amazon will cover everything in the room in very fine white powder after a few weeks/months, which gets super annoying. The evaporative-type humidifiers don’t do that. Not sure about smart-plug compatibility, though.
