Which humidifiers can be automated?

[SillyKeiki]

My humidifier recently died, and I would like to buy a new one, but I have a very particular project in mind for my new humidifier.

I want to have it automated (domotized?) with a smart plug. These smart plugs can be controlled via app to turn on/off the power. That way I would be able to control the humidifier connected to it from anywhere.

However, there are some requirements to meet if I want to do this: the humidifier must not have electronic buttons. It must have only a physical on/off button that can be left on the ON setting so that turning on the power will automatically activate it. I don't know if I have explained myself properly.

I would like it to have at least 4L capacity at least as well.

Any suggestions? Anybody is using the same method and could share which humidifier model they are using?

EDIT: I am referring to cool mist humidifiers.
