I’m not any kind of expert but I seem to recall that turning air conditioners off and on with a switched outlet is a bad thing… something to do with how they start and stop the compressor.
Also, unless you have no choice, stick with the dual hose models, because the single hose ones end up pushing conditioned air out the window. Even if a single hose model has a theoretically higher efficiency, it won’t translate to the real world because it’s blowing cooled air out the window.
Hacking something to replace the unit’s power button is probably your best option
