I'm looking for a wifi smart plug/outlet that has a timer feature so that when the plug is plugged in the timer activates and shuts off power after a programmed time. To turn it back on you need to replug or press a reset button. My need arises from putting a portable A/C unit in my Airbnb and want to avoid guests running it 24/7 or when they aren't home. I figure having a 3-4 hour timer would be sufficient. I've tried doing some research but product descriptions aren't very clear with what features are available or what they do specifically. Maybe someone has some other suggestions of ideas that might work for my situation as well?
